Kalpana chatushka (tetrad on applications of medicine) starts with the chapter on oleation therapy. This chapter describes details of oleation therapy including the source of lipids, their types, properties, administration method, time, dose, alternative methods of administration in the form of recipe (vicharana). It also describes the indications, contraindications, symptoms of proper, inadequate and excess oleation. Adipose tissue in the form of fat is essential component of body. It provides lubrication to all viscera and other interstitial spaces due to its unctuous property. Lipids are integral part of cell membrane that allows entry of lipid soluble substances/drugs into the cells. The selection of lipids for oleation therapy depends upon the specific integrity of gut, severity of the disease, and specific indications of lipids. Lipids processed with medicines can be prescribed in diabetes or skin diseases where natural fat is contra-indicated. Apt oleation therapy results in normal functions of vata, increase in digestive power, softening of (hard) feces, and making the body supple and soft. Improper implementation of methods or violation of guidelines, results in complications such as skin diseases, itching, hemorrhoids, ascites, fainting, indigestion etc. Oleation and sudation (induced sweating) are pre-requisites or pre-treatment procedures for purification (shodhana) therapies to aid in moving vitiated dosha to gut (for an eventual expelling out of the body and achieve purification). The present chapter can be considered as a first step in purification therapies described.
Keywords: Sneha(lipids), snehana (oleation therapy), fat and lipid metabolism, abhyanga (therapeutic massage), ghee, oil, marrow, fat, alternative options for oleation therapy, indications, dose, clinical applications.
The chapter Snehadhyaya is the first chapter of Kalpana Chatushka (tetrad describing planning of purification therapies). It follows the Vatakalakaliya Adhyaya, the last chapter of Nirdesha Chatushka (tetrad describing guidelines for clinical practice). This sequential order of the tetrad suggests the logical progression in the clinical training of Ayurveda learners – from a foundational course in therapeutics to more specialized procedures (including purification therapies). Oleation (Snehana) is the first step before purification therapies, like therapeutic emesis [vamana] and therapeutic purgation [virechana], and is also the best medicine suggested for vitiated vata - the key pathological factor responsible for many diseases.
History and broad outline of chapter
The earliest reference to snehana is found in the ancient text Markandeya Purana where ghrita (clarified butter), taila (oil), vasa (muscle fat) and majja (bone marrow) were quoted as sneha drugs (Mar. 165, 166, 244-245). However, a detailed description of snehana- swedana (sudation) with complications and their treatments is only found in Charak Samhita and related Ayurveda texts. The Snehadhyaya provides comprehensive information about sneha (lipids) and snehana (its therapeutic administration/oleation).
Sneha (lipids): Sneha is any substance that produces unctousness, softness, moisture, increased secretions etc. in the body. [Cha.Sa.Sutra Sthana 22/11] Sneha is predominantly composed of basic elements - prithvi (earth) and jala (water). [Su.Sa.Sutra Sthana 41/11] Hence it is responsible for moisture [Hemadri on A.H. Sutra Sthana 1/18], providing softness to the body while also playing a major role in producing strength. [Su.Sa.Sutra Sthana 46/516] Sneha qualities can be described using adjectives such as guru (heavy), sheeta (cold), sara (agility), snigdha (unctuous), manda (slow), sukshma (penetrating), mridu (soft), drava (fluid), and pichchila (slimy). [Cha.Sa.Sutra Sthana 22/15] and [A.H. Sutra Sthana 16/1] These qualities make oleation therapy a prerequisite for most of the Panchakarma (five purification) procedures since they help in ejecting impurities out through the gut. All dhatu (body tissues) require sneha for growth and maintenance. Sneha adds unctuousness to food preparations, necessary in the process of digestion. [Cha.Sa.Chikitsa Sthana 15/6] Kapha and pitta are two basic doshas that have snigdha i.e. unctuousness. [A.H. Sutra Sthana 1/11-12] Sneha therapy is mainly indicated for alleviation of vata dosha, which is the main etiological factor responsible for most diseases. Modern science also gives importance to fats. Vitamins A, D, E, and K are fat-soluble , meaning they can only be digested, absorbed, and transported using fats. Fats are also sources of essential fatty acids, an important dietary requirement. Fats play a vital role in maintaining healthy skin and hair, insulating body organs against shock, maintaining body temperature, and promoting healthy cell function.
The glycerol formed from catabolism of fats can be converted to glucose by the liver and thus used as a source of energy. Fat also serves as a useful buffer against a host of diseases. When a particular substance - chemical or biotic—reaches unsafe levels in the bloodstream, the body can effectively dilute, or at least maintain, an equilibrium of the offending substances by storing them in a new fat tissue. This helps in protecting vital organs, until such time as the offending substances could be metabolized and/or removed from the body by such means as excretion, urination, accidental or intentional bloodletting, sebum excretion, and hair growth. Beside pacifying vitiated dosha, enhancing nutritional value and aiding in metabolic functions, sneha can be utilized for body purification, as described earlier. Sneha i.e. fats like ghrita, oils etc. are used for Panchakarma and related purification processes since fats are essential component of cell membrane and thus, have easy access to all parts of the body. Fats have multidimensional properties that can be utilized for therapeutic purpose. Thus, this chapter on sneha is important from the standpoint of therapeutics.

To remove all doubts (of Agnivesha), Punarvasu replied, “Dear (Agnivesha) snehayoni (sources of fats) are of two types: Sthavara (Vegetable origin) and Jangama (Animal origin).
Among sthavara (plant fats), tila (sesame), priyala (Buchanania lanzan), abhishuka (pistacia vera Linn), vibhitaka (belliric myrobalan), chitra (Baliospermum montanum, or red physic nut), abhaya (chebulic myrobalan), eranda (Ricinus communis), madhuka (madhuka indica), sarshapa (mustard), kusumbha (Brassica nigra Koch), bilva (Aegle marmelos Corr, or bael fruit), aruka (Prunus persica Linn), mulaka (Raphanus sativas Linn, or radish), atasi- Linseed (Linum usitatissimum Linn), nikochaka(pistachio), akshoda (Aleurites moluccana, or wild walnut), karanja (Indian beech-Pongamia pinnata Merr), shigruka (Moringa oleifera Lam, or drumstick) contains fat suitable for consumption. Among jangama (animal fats), matsya (fish), mriga (antelopes) and pakshi (birds), curd, milk, ghee, meat, muscle fat and bone marrow are the animal sources of fat. [9-11]

Among all varieties of oils, sesame oil is considered the best and is ideal for giving strength and unctuousness. Castor oil is the best for virechana (purgation). It is pungent, ushna virya (hot potency), alleviates vitiated vata and kapha, guru (dense, viscous or heavy) in nature and when used with astringent, sweet, bitter drugs it also helps mitigate aggravated pitta. 
Four major lipids
सर्पिस्तैलं वसा मज्जा सर्वस्नेहोत्तमा मताः| एषु चैवोत्तमं सर्पिः संस्कारस्यानुवर्तनात्||१३||
sarpistailaṁ vasā majjā sarvasnēhōttamā matāḥ| ēṣu caivōttamaṁ sarpiḥ saṁskārasyānuvartanāt||13||
sarpistailaM vasA majjA sarvasnehottamA matAH| eShu caivottamaM sarpiH saMskArasyAnuvartanAt||13||
Ghrita (clarified butter), oil (of sesame), vasa (muscle fat) and majja (bone marrow) are considered the best sneha. Among these, ghrita is superior as it possesses the qualities of samskara i.e. blending with other substances having different properties without losing its own properties.

- Ghrita alleviates pitta and vata, and is beneficial for rasa, shukra and ojas. Provides relief from burning sensation, softens the tissues, improves voice and complexion. 
- Sesame oil alleviates vitiated vata, does not aggravate kapha (rather, it improves strength). It is very beneficial for the skin, ushna virya, increases stability, and purifies or cleanses the vagina/ uterus. 
- Vasa (muscle fat) is useful in healing punctured wounds, fractures, accidental trauma, prolapsed vagina, pain in ear and head, enhancing virility, oleation and for those doing physical exertion. 
- Majja (bone marrow) improves strength, semen, rasa, kapha, meda and majja. It especially strengthens bones and useful for oleation. 
Time of administration
सर्पिः शरदि पातव्यं वसा मज्जा च माधवे| तैलं प्रावृषि नात्युष्णशीते स्नेहं पिबेन्नरः||१८||
sarpiḥ śaradi pātavyaṁ vasā majjā ca mādhavē| tailaṁ prāvr̥ṣi nātyuṣṇaśītē snēhaṁ pibēnnaraḥ||18||
sarpiH sharadi pAtavyaM Vasa Majja ca mAdhave| tailaM prAvRuShi nAtyuShNashIte SnehaM pibennaraH||18||
Ghrita (ghee) should be consumed in sharada (autumn) season, while vasa (muscle fat) and majja (bone marrow) in madhava (spring) season, and taila (oil) during pravrita (early monsoon). Sneha should be consumed at a time when it is neither very hot nor cold. 
वातपित्ताधिको रात्रावुष्णे चापि पिबेन्नरः| श्लेष्माधिको दिवा शीते पिबेच्चामलभास्करे||१९||

vātapittādhikō rātrāvuṣṇē cāpi pibēnnaraḥ| ślēṣmādhikō divā śītē pibēccāmalabhāskarē||19||
In case of aggravation of vata - pitta dosha, and in hot (summer) season, sneha should be consumed at night (evening time). In aggravation of kapha and in cold season, it should be consumed at day time. 
अत्युष्णे वा दिवा पीतो वातपित्ताधिकेन वा| मूर्च्छां पिपासामुन्मादं कामलां वा समीरयेत्||२०||

Sneha consumed at night during cold season or by person who has great aggravation of kapha, can causes diseases such as flatulence, loss of taste, pain in abdomen, or anemia. [20-21]
Vehicle for lipids
जलमुष्णं घृते पेयं यूषस्तैलेऽनु शस्यते| वसामज्ज्ञोस्तु मण्डः स्यात् सर्वेषूष्णमथाम्बु वा||२२||

[23-25]
Preferred form of lipid

Dose of sneha: Dose is divided into maximum, moderate and minimum based upon the time taken for it to get digested as follows:
- Pradhana (maximum): Dose that digests in one day and night (24 hours).
- Madhyama (moderate): Dose that digests in one day (12 hours).
- Hrasva (minimum): Dose that digests in half day (6 hours).
Thus, these three doses of sneha are administered by size (or quantity) of the dose, keeping in mind their ability to get digested. Further I will explain to you their usage depending upon individual patient. [29-30]
Persons suitable for maximum dose and its benefits
Those persons who consumes large quantity of sneha daily, those who can tolerate hunger and thirst, whose digestive and bodily strength is strong, who suffer from gulma (inflammation in digestive tract), snakebite cases, patients of visarpa (erysipelas), unmada (insanity), mutrakrichchra (dysuria) and constipation are advised to consume maximum dose of sneha. Maximum dose when used correctly quickly cures diseases. It removes excess of vitiated dosha out of the body, reaches all body channels, improves strength and rejuvenates the body, sense organs, and the mind. [31-34]
Persons suitable for moderate dose and its benefits
Patients of arushka (eruptions on scalp), sphota (vesicles), pidaka (big eruptions), itching, pama (scabies), kushtha (skin disorders), prameha (diabetics), vatashonita (gout), those who never consume large quantities of food, those with mridukoshtha (soft bowel habit) ,and those having moderate strength are advised to consume moderate dose of sneha.
A moderate dose never causes any serious complication. It never reduces strength, provides oleation with ease, and can be used for shodhana (body purification). [35-37]
Persons suitable for lowest dose and its benefits
Those who are old, young (children), those with tender physique, living luxurious life, those who cannot tolerate hunger or have difficulty with empty stomach, those suffering from poor digestion, patients suffering from fever, diarrhea and cough, those having poor body strength are advised to consume the smallest dose of sneha.
The lowest dose of sneha has minimal restrictions for its consumption. It does oleation and produces stoutness in the body, acts as an aphrodisiac, gives strength to the body, never causes any complication and can be used for longer duration. [38-40]

On the day before administration of sneha, one should take warm, liquid diet in proper quantity. The food should not increase secretions, possess unctuousness or material with opposing properties.
If sneha is for the purpose of samshamana (pacification of dosha internally), it should be taken at the time of meals and if meant for shuddhi (purification) it should be given when food consumed in the previous night has been digested. [60-61]

- Do not suppress the urge to pass feces, urine, flatus and belching
- Do not engage in physical exercises and rein in emotions, talking loudly, getting angry, or becoming upset, etc
- Do not get sleep or sit while exposed to snow, sunlight and breeze
One who after consuming sneha takes oily food and does not follow the aforementioned guidelines gets affected by severe diseases. [62-64]

Individuals with soft bowel movement require a maximum dose of three days of acchapana (sneha alone) while those suffering from krura koshtha (hard bowel) require the seven-day long (maximum) dose regimen.
Individuals with soft bowel movement require the following as purgatives: jaggery, sugarcane juice, whey of curd, milk, water of curd, milk pudding, krishara (rice cooked with black gram), ghee, juice (decoction) of kashmari (Gmelina arborea), triphala (combination of Terminalia chebula, Terminalia bellirica and Emblica officinalis), pilu (Salvadora persica Linn.), draksha (Vitis vinifera Linn), warm water or fresh wine.
These do not help an individual suffering from hard bowel movement because of the prominence of vata in their grahani (duodenum). “Soft bowel individuals” have predominance of pitta and less kapha and vata in their duodenum, and hence gets purgation easily. [65-69]

Individuals with highly aggravated pitta in duodenum have excessive digestive strength, and therefore are able to digest or metabolize fat easily. Since their ojas gets displaced and their digestive power produces thirst, even great quantities of solid food consumption does not quench the fire stimulated by drinking fat, and therefore they do not find relief even with cold water. They suffer from the burning sensation of agni in them as if they have ingested snake venom.
When the sneha consumed does not undergo digestion and there is thirst then the physician should get it out through emesis, make the patient drink copious amounts of cold water, eat dry food items, and then make him vomit again.
Ghrita should not be taken when only pitta is increased and especially when there is ama in the body. Consuming ghrita in such cases could change the physical complexion of the person to that of pitta, lead to loss of consciousness or even death.
Stupor, nausea, flatulence, fever, rigidity of the body, skin diseases, itching, pallor, edema, hemorrhoids, tastelessness, diseases of stomach and duodenum, feeling of numbness, loss of speech, abdominal pain, and various diseases related with ama could be caused by improper administration of sneha. In these conditions, oleates should be ejected out of one’s system using emesis or sudation. The physician should then give mild purgation, after an interval of time, and also factoring in the severity of the disease and the condition and predisposition of the patient. Administering takrarishta, using dry food items, drinking cow urine and consuming triphala are some of the medicines recommended for cure of complications caused by the consumption of sneha. [70-78]

Therapeutic purgatives should be given three days after sneha consumption and during these three days warm and creamy (unctuous) mamsa rasa (mutton soup) and rice should be consumed. Therapeutic emesis should be administered a day after stopping sneha , and guidelines for purgation should be followed.[80-81]

Persons who dislike sneha, use fats daily, have soft bowel, can withstand strain, and who consume alcohol often are suitable for vicharana (therapy involving administration of fats mixed with other food items or preparations). Soup of meat of lava (common quail), taittira (black partridge), peacock, swan, boar, fowl, cow, goat, urabhra (wild sheep) and fish help in oleation.
A person with excessive dryness in body should consume the following: yava (barley), kola (Bengal gram), kulattha (two flowered dolichos) mixed with fats, jaggery and sugar, juice of dadima (pomegranate), curd added with vyosha ( combination of black pepper, ginger and long pepper), sesame consumed before food, phanita (molasses) added with fats, krishara (rice cooked along with sesame, mutton etc.) added with more fats, tila kambalika (buttermilk cooked with more of tila), phanita (molasses) and sringavera (ginger) or oil of sesame added to sura (beer), roasted meat of animals . He should take meals after this is digested.
Warm milk directly from the udder of the cow added with fat, or milk added with sugar, or dadhisara (precipitate of curd) mixed with phanita (molasses), or panchaprasrita peya, or payasa (milk pudding) mixed with powders of masha (black gram) or many fats cooked with milk acts as an effective preparation for oleation.
Peya (gruel) prepared with one prasrita (96 gram) each of ghrita, oil, muscle fat, bone marrow and rice is known as panchaprasritiki peya. This peya, or drink, may be consumed by the person desirous of oleation. [82-90]

For oleation of patients suffering from skin diseases, edema and diabetes, one should not use meat of animals either domesticated, or of marshy regions or those living in water. Jaggery, curd, milk and sesame seeds are also to be avoided. They should be given suitable fat boiled with pippali, haritaki or triphala. The physician may prepare sneha by boiling it with draksha (grape), amalaki (emblica officinalis) or with sour curd added with vyosha (combination of black pepper, ginger and long pepper). The sneha processesd with decoction of yava (barley), kola (Bengal gram), kulattha (two flowered dolichos), yava kshara (alakali prepared from yava), sura(beer), curd, milk and ghee is best in these cases. [91-94]

Just as a piece of cloth only absorbs water as much as it can and leaves off the excess, similarly agni (digestive power) digests fat as much as it can and expels the excess from the body. Just as a mud ball expels excess water without getting over-moistened when water is poured over it quickly, similarly the body expels fat that has been consumed very quickly. [96-97]
Use of salt to expedite oleation

Sneha added with salt produces oleation quickly since salt is abhishyandi (produces more moisture in the tissues), not dry, subtle (enters minute pores), hot in potency and vyavayi (spreads to all parts quickly and then undergoes digestion). 
Sequence for oleation and sudation

Tattva Vimarsha (Fundamental Principles)
- There are two sources of lipids recommended for oleation: vegetable and animal origin. Ghrita (Clarified butter), oil (of sesame), vasa (muscle fat) and majja (bone marrow) are the best forms of lipids. [9-13]
- These lipids are essential for pacifying dosha and maintaining equilibrium. Ghee or ghrita is the best processing media as it adopts the properties of the processed drug without losing its own properties. Ghee pacifies vata and pitta. Oil pacifies vata without aggravating kapha. Muscle fat is best for improving virility and helpful in healing fractures and dislocations. Bone marrow is specifically beneficial for enhancing strength of bones, bone marrow and shukra (sperms). [13-17]
- The ideal season for administration of ghee is sharada (autumn), that for muscle fat and bone marrow is vaishakha (mid April to mid May), and the time for oil administration is pravrit (early rains). 
- Lipid shall be administered according to its indication, at specific time, with correct vehicle, and for a specific duration. Otherwise improper administration may lead to severe disorders. [19-22]
- The dose of lipids intended for purification treatment should be decided as per the digestive capacity of the recipient. The time taken for complete digestion of consumed lipid shall be considered. Thus, the dose is essentially personalized. 
- The effects of lipids are dose dependent. The larger dose, medium dose and small dose have different pharmaco-dynamic effects and different indications. [30-40]
- Ghee, oil, muscle fat and bone marrow have specific receptors that decide their indications, systemic effects and end results. [41-50]
- Oleation therapy shall be administered until the desirable signs of proper oleation are observed. Specific diet and lifestyle shall be followed during oleation therapy, otherwise it leads to severe diseases. [57-64]
- Duration for oleation therapy is three to seven days.
- Oleation leads to aggravation of kapha dosha in body. The status of kapha is key factor for deciding time of therapeutic emesis or purgation. Therapeutic emesis shall be prescribed immediately after one day of completion of oleation therapy when kapha is in aggravated state. Therapeutic purgation shall be prescribed when the kapha is less in body i.e. after three nights of completion of oleation therapy. [80-81]
- Oleation followed by sudation are essential procedures before body purification. These two are performed before purification in order to channelize dosha from shakha (periphery) to koshtha (gut). 
Vidhi Vimarsha(Applied Inferences)
Sources of Sneha
Sneha i.e. fats that are available today can be categorized in sthavara (vegetable origin) and jangama (animal origin) as a part of therapeutics or dietetics. E.g.
Sthavara Sneha (vegetable sources)
Mineral oil, olive oil, palm oil, soybean oil, rapeseed oil, sunflower oil, peanut oil, cottonseed oil, coconut oil, rice bran oil, grape seed oil, corn oil, hazelnut oil etc. Moreover, most of essential oils used in cosmetics and therapeutics are also sthavara type, as they are derived from sections of plants. For e.g. rose oil, clove oil, peppermint oil, cedarwood oil etc.
Jangama Sneha (Animal sources)
Cod liver oil, shark liver oil, all ghee, milk, milk products, curd, all types of meats, etc. are sources of animal fats.[verse 9-11]
Reasons for superiority of sesame oil
Sesame oil is considered the best among all oils because it provides strength and unctuousness in body. It is ushna (hot) in nature, possesses kapha-vatahara (pacifying kapha and vata dosha) properties, and is beneficial for voice and complexion. It also cures fractures and dislocations, purifies dhatu (body tissues) and vrana (wound). [Ka.Sa.Sutra Sthana. 22/7] Ongoing research also indicates that the rich presence of antioxidants and polyunsaturated fats in sesame oil could help control blood pressure.
Due to high Vitamine E content , Sesame oil is an antioxidant and improves skin health and complexion while also lowering cholesterol levels. Sesame oil also contains magnesium, copper, calcium, iron, zinc, and vitamin B6. Copper provides relief for rheumatoid arthritis. magnesium supports vascular and respiratory health. Calcium helps prevent colon cancer, osteoporosis and migraine. Zinc promotes bone health. Clinical studies have shown that a sesame oil massage of infants improved their weight and length, as well as their mid-arm and mid-leg circumferences.
Properties of Castor oil
The United States Food and Drug Administration (FDA) has categorized castor oil as "generally recognized as safe and effective" (GRASE) for over-the-counter use as a laxative with its major site of action in the small intestine (where it is digested into Ricinoleic acid). At low doses, castor oil is readily absorbed. As the oral dose increases, percent absorption decreases and laxation occurs. Castor oil is widely used in treatment of musculo-skeletal and spine disorders. It is considered useful in ama dominant conditions like rheumatoid arthritis where less absorption of sneha, vata alleviation and body purification are expected simultaneously. Castor oil in large doses is administered for therapeutic purgation. [verse 12]
Best Sneha and their Therapeutic Applicabilities
Ghrita (clarified butter / ghee)
Ghee is the best oleate due to prominence in its unctuousness. This property of fats is indicated by saponification value which is highest in ghee ( 225-235 ) as compared to sesame oil (188-193),and animal fat (190-205) etc. Samskara (processing) leads to transformation of inherent attributes of a substance. But this change is due to changes in the basic composition of a drug. Ghee has a unique quality to adopt properties of herbs processed with it without losing its own. If ghee is processed with drugs with nourishment properties, then it is indicated in degenerative diseases. If it is processed with drugs having hot and strong properties, then it is indicated in obstructive diseases. Therefore, it is considered as the best media for processing. One or the other medicated ghee preparation is indicated in almost all diseases. It pacifies vata due to snigdha guna (unctuous properties) and pitta due to madhura (sweet) and sheeta (cold) properties. [Cha.Sa.Nidana Sthana 1/39] It increases shukra and ojas due to similar properties.
Vasa (muscle fat)
Vasa i.e. intramuscular fat is a normal content of human body and its function is to lubricate the muscles while also serving the role of a fat store to be used up by the body when subjected to energy-intensive activities, such as physical workouts where it may contribute up to 20% of total energy turnover. This is a possible reason for it to be recommended for individuals engaged in intensive physical acitivities, as well as for oleation therapies.
Majja (bone marrow)
Bone marrow contains about 96 percent fat. It contributes to 50 to 175 g of protein required by body each day. It has all the amino acids needed for good health. Each serving of marrow provides 3% of the calcium required each day. Calcium is commonly understood to strengthen bones and decrease risk of developing brittle, easily-broken bones as one gets older. All these factors explain why bone marrow is beneficial, especially for one’s bone health. In Ayurvedic clinical practice, soup of bone marrow is prescribed for osteoporosis and degenerative disorders of the vertebrae.[verse 13-17]
Proper season and time for sneha consumption
The proper season for consumption of a sneha depends upon the physiological dominance of dosha in the body during that particular season, as well as the inherent properties of the sneha. On the basis of its inherent properties, ghee is indicated in sharada (autumn) season, when pitta dosha is increased. Muscle fat and bone marrow do not possess much hot or cold potency, and hence are advised in sadharana kala (i.e. seasons that are not very hot or cold), except in Chaitra month (mid-March to mid-April) when it may vitiate kapha dosha. Oils are the best medicines for vata, hence they are recommended for consumption in the pravritta (early rainy) season. These rules are to be followed universally according to seasonal and temperature variations. If this is not followed, then complications in oleation therapy could be observed.[verse 18-21]
Anupana (after consumption)
Most of the sneha gets stuck in upper gastrointestinal tract due to stickiness. The vehicles or after-drinks assure proper transport of the sneha (oleate or lipid or fat) to its intended site of digestion and absorption, and help in proper metabolism to increase bio-availability. However, those after-drinks should not affect the actions of the sneha. Warm water liquefies ghrita and facilitates its transport and absorption. Similar facilitation is seen in the use of lentil soup and scum of gruel after consuming oil and vasa-majja respectively. However, warm water is usually accepted as an after-drink in all cases of sneha consumption (with an exception of bhallatak and tuvaraka oil.)[verse 22]
Pravicharana (medium of administration)
Pravicharana implies the medium of administration of sneha advisable for those who need to undergo oleation therapy but are unfit to consume sneha as such. In such cases, optional modes of administration of oleation are suggested based on palatability of the oleate and the tolerance (and the digestive power) of the person. Ideally, food and external applications are considered as Pravicharana. Cooked rice, gruel, meat juices etc. mixed with fats are administered and external massage, unctuous enema, oil through nose and ears etc. are considered optional modes of administration of oleation therapy.[verse 23-25]
Acchapana (drinking fat alone) as a preferred mode for oleation
There are number of factors that affect the absorption of any drug ,
- Total surface area available for absorption of fat
- Contact duration at the absorption surface
- Quantity of food in the gastro-intestinal Tract
- Gastrointestinal pH changes
- Gastric emptying time & rate
- Pancreatic and intestinal enzymes
- Bile acids & biliary function
- Gastrointestinal flora
- Drug/food interaction
Dose of sneha
The recommended dose of sneha would be different for every individual, depending upon the individual’s agni (digestive capacity), koshtha (bowel habit) etc. However, for ease in therapeutic applicability, specific doses in pala, karsha etc. are advised by Arunadatta in his commentary on Ashtangahridaya (Sutra Sthana Chapter 16/17). Two pala (96 ml) as minimum, four pala (192ml) as medium, and six pala (288ml) as maximum dose have been suggested. Sharangadhara (Madhyama Khanda 1/7) and Bhavamishra (Bhavaprakash I-79 iv. 6) suggest the quantities of one pala (48ml), three karsha (36ml) and two karsha (24ml) as the best, medium and least doses respectively.[verse 29-30]
In a research on 29 individuals, it is observed that increasing dose of fat after considering status of agni and bowel habit of individuals gives better results in oleation therapy. The onset of various symptoms of adequate oleation occur in a sequential manner which is helpful in predicting the duration of oleation and signs of oleation in gastro intestinal tract and peripheral tissues.
Deciding suitable dose
Ayurveda acharyas have advised three dosage forms - high, medium and low doses. The following points need to be considered to determine the applicable dose for an individual:
- Severity of disease
- Habitual use of sneha in diet
- Agni (digestive power)
- Body strength
- Purpose of oleation
When a disease is severe or chronic in nature, it implies a “deep-seated” or a chronic case of (vitiated) dosha, blockages in microchannels, besides other imbalances and complications. In such conditions, the highest possible dose could be necessary to channelize and eject the dosha from its “seat” towards the gut. This quantity is beneficial for disorders of mind and sense organs. However, the patient needs to have strong digestive capacity and good strength of patient to be able to tolerate the highest dose. The body of the patient adapts to an increased fat intake (thereby increasing the rate of oxidation of fat) by two mechanisms:
- Expansion of the fat stores or
- Maintenance of the glycogen stores in a lower range.
Thus, for those using sneha routinely in diet, oleation is possible only when natural habitual intake of fats is exceeded to overcome this adaptation. This is also the possible reason for daily increase in dose of sneha, so that body can not get adapted to the dose administered on day before. Seven days is maximum duration for sneha consumption because sneha is adapted by body easily after seven days (Cha. Si. 1/7). This is based on the fact that for purpose of energy balance body adapts to fat oxidation within seven days of increased fat intake.
The medium dose is suitable when disease is of moderate severity, in person having soft bowel, moderate diet and strength. This dose is enough to reach all over body as there is less obstructions, no fat adaptation, hence produce least complications. This is the ideal dose for purification therapies.
Lowest dose of sneha consumption is fat substitute for diet. Thus, it holds more calorie contents, which strengthens body and is free from any complications. It can be used in old persons and children.[verse 31-51]
Formula for calculating strength of agni
Bio-fire (Agni) Strength Index (BSI) = (Total Dose / Given Dose) × T.
T = Time taken for the digestion of Ghee.
Lesser the BSI, more will be the intensity of bio-fire.
Indications of oleation
Oleation and sudation are essential pre-purification therapies to channelize dosha from all body parts to the gut.
Sneha in regular exercise
Those doing regular exercise require high calorific diet to maintain body weight and healthy fat deposits in the body. Hence sneha consumption is necessary for them. Fats also serve as energy stores for the body, containing about 37 kilojoules of energy per gram (8.8 Cal/g) (the highest in comparison to those of proteins and carbohydrates which provides 4 Cal/g of energy).  In case of starvation, fats are broken down in the body to release glycerol and free fatty acids. Glycerol is further converted to glucose by the liver and thus used as a source of energy.
Sneha in chronic alcoholics
Alcoholics gain weight because of excess energy intake with food and inhibition of fat oxidation from alcohol. But chronic alcoholics (Madyanitya) show a lower body weight due to fat mass reduction. This alteration could be due to induction of the non-alcohol dehydrogenase pathway, likely the microsomal ethanol oxidizing system. Moreover, ethanol might have direct effects on human adipocytes. Therefore, sneha is indicated in chronic alcoholics.
Sneha in excessive sex
Those who are involved in excessive sexual activity lose their ojass (vitality) leading to dhatukshaya (depletion of dhatu), vata aggravation and loss of unctuousness as mentioned in the pathology of rajayakshma. [Cha.Sa.Chikitsa Sthana 8/24-25] Hence oleation is required in such debilitated persons.
Contraindications of Sneha
Sneha is mainly contraindicated in conditions where there are excessive body secretions especially from mouth and rectum, ama formation, poor digestion, excess aggravation of dosha, and in cases where other therapies such as nasya and basti are being administered. Oleation therapy worsens the condition in these cases. [verse 52-56]
Signs of inadequate, proper and excess Sneha
Inadequate oleation does not pacify vata and disturbs agni leading to poor digestion. Proper oleation due to proper sneha improves digestion. The skin acts as a water resisting barrier to prevent flow of essential nutrients out of the body. The nutrients and oils that help hydrate the skin are covered by the outer layer of skin, the epidermis. Softness or tenderness of skin is a result of proper oleation since snehana adds to the functional improvement of fat deposits of the body. Excess oleation causes improperly formed faeces, which may be due to increase in colorectal transit time as a result of excess unctuousness in gastrointestinal lumen. Stools are formed in the colon in the last phase of digestion. Through peristalsis, the muscles of the colon and the abdomen advance the liquid feces through the colon and compress the fecal matter into stool. During this process the colon extracts water from liquid feces as it passes down. The water is absorbed by the lumen, leaving the larger waste particles to be further tumbled along and formed into stools. Due to excess oleation, blockage of microchnnels and villi occurs and absorptive function may become hampered leading to improperly formed stool. All other symptoms of excess oleation are due to increase in kleda (moisture) in body leading to heaviness, loss of digestive strength etc.[verse 57-59]
Do’s and Don’ts after Sneha Consumption
Guidelines to be followed after sneha consumption are intended:
- To maintain digestive power at optimum quality
- To avoid any physical exertion
- To keep mental balance intact
- To avoid any etiological factors for production of diseases.
Digestion and physical activities are associated with large and sometimes opposite changes in several physiological parameters. Gastric acid secretion during digestion causes increased levels of plasma bicarbonate ([HCO-3] (pl)), whereas activity leads to a metabolic acidosis with increased lactate and decrease in plasma bicarbonate. Thus naturally to keep digestion of sneha at optimum, person needs to avoid excess physical exertion.
Emotions affect physiological processes and actions which are responsible for nutrient malabsorption and digestive health. Saliva becomes more acidic under stress, depression and negative emotions due to alteration in salivary digestive enzyme, ptyaline. The negative emotions also affect the production of pepsin in the stomach, enzyme release from the pancreas and also liver bile flow. Anxiety, is responsible for "fight or flight" response, that takes up a lot of brain's resources, so to compensate it slows down parts of brain that are not as necessary, such as the muscles involved in digestion. Anxiety can also cause low serotonin, and that means that some of the messengers that are normally traveling into body are possibly being created at a lower rate, leading to digestive disorders. During the fight or flight response, body creates massive amounts of adrenaline to give extra energy. In order to create that energy, adrenaline needs to take it from "sugar storage" - While adrenaline does this, body starts processing nutrients at rates that aren't ideal. It changes how body processes nutrients as well and could conceivably affect digestive health. All these factors collectively may cause adverse effects of sneha due to impaired digestive power. Therefore, avoiding negative emotions is important in oleation therapy. Avoiding breeze, snow, sunlight etc. are a must in order to avoid any environmental infections or altered immune responses.[verses 62-64]
Bowel habits and duration of oleation therapy
Koshtha i.e. bowel habits are the outcome of dosha dominance in bowel. Vata, pitta and kapha dominance causes krura (hard), mridu (soft) and madhyam (moderate) koshtha (bowel habit) respectively. Vata due to its ruksha (dry) [Indhu on A.S. Sutra Sthana 1/ 11] properties causes fast absorption of sneha and also requires large doses and longer duration for complete oleation. Pitta has natural unctuousness associated with it due to its ushna (hot), sara (easy for dispertion), and drava (liquid) [A.H. Sutra Sthana 1/11] properties. These properties aid in the flow of sneha across all body parts and hence, an early push of dosha towards the bowel requires least dose and minimum duration. Kapha has similar properties as sneha. However, the bowel habit in a kapha person is moderate due to its sthira (stable) and sticky properties. [A.H. Sutra Sthana 1/12] Modern science also explains bowel habits, its effects and considers intestinal transit time responsible for it. 40-45 hours is the normal bowel or in Ayurvedic terminology madhyama koshtha person’s intestinal transit time. If it stays in the gut for longer than that, fluid is re-absorbed into the body and the stool becomes harder and dryer. Body secretes about eight liters of fluid during the course of a day —from the stomach, salivary glands and pancreas—to decompose food and push it through the digestive system. But if food passes through too quickly, there isn’t enough time for all of that liquid to get absorbed, and the stool emerges in a semi-solid or liquid state. Thus, it is the physiological differences based on intestinal transit time that decide the duration of oleation therapy. The nature of a food item or a drug ingested affects bowel movement and explains the differences mentioned above.[verses 65-69]
Complications of oleation therapy
Excessive thirst is a result of impaired digestion and absorption of lipids. Alpha-linolenic acid (an omega-3 fatty acid) and linoleic acid (an omega-6 fatty acid) are essential fatty acids supplied by almost all polyunsaturated fats. But any defect in their absorption may cause deficiency leading to excessive thirst and dry skin, brittle hair &nails, sleep and attention problems.
Bile, to some extent acts as a surfactant, helping to emulsify the fats in food. Without bile salts, most of the lipids in food would be excreted in feces, undigested leading to steatorrhea and vitamin deficiency. Thus sama pitta (pitta that is not formed well) can be due to improper functions of biliary system that can not digest fats properly and produce severe symptoms. Moreover, fats boiled with some medicines may cause correction in this metabolic defect thus advocated in sama pitta condition.
All the diseases produced as complications are basically of kleda (moisture) dominant and ama dominant in nature, hence dry, amapachaka drugs are indicated in therapy. Medicated buttermilk is indicated to counter the complications of oleation therapy. [Cha.Sa.Sutra Sthana 2/30] Therapeutic emesis, therapeutic purgation are prescribed to remove undigested sneha from gut preventing further complications.[verse 70-79]
Shodhana (purification) after oleation
Vamana (therapeutic emesis) is done in utklishta kapha (therapeutically aggravated kapha by oleation) condition. Virechana (therapeutic purgation) is done when kapha is reduced in body. [Cha.Sa.Siddhi Sthana 1/ 8-9], Hence, the rest period for performing virechana after oleation is more (three days) than that of vamana.[verse 80-81]
Vicharana (alternative methods of fat administration)
Sneha consumption alone is generally associated with considerable degree of nausea. Also, persons living luxurious lifestyles hate therapeutic fat consumption. Those habitual to fatty diets need larger doses of fats which in turn results in nausea. Soft bowel persons are naturally have rapid intestinal transit rate. Due to this, less fat absorption occurs and excreted without digestion. Those who cannot tolerate exertion also suffer from nausea due to sneha administration. Those having alcohol addiction can not suddenly discontinue their habit and thus they need fats to be given in some form of alcoholic preparation.
Benefits of pravicharana in palatability and taste perception
- Pravicharana can change the physical nature of sneha by addition of different substances.
- It may change chemical property to some extent by samskara (transformation)
- It can stimulate or inhibit cholecystokinin- pancreozymine secretions.
- Also, sneha can be made more palatable and pleasant to mind by considering taste.
Some important properties of vicharana have been enumerated in the following table:

In patients suffering from skin diseases, edema, diabetes, meat of domesticated animals and animals from marshy lands , or of aquatic animals is contraindicated. Moreover, jaggery, curd, milk and sesame are also not suitable for vicharana. All these articles increase moisture content in body causing aggravation of symptoms.
Mode of action of sneha
Sneha acts as a solvent and it increases apyamsha (liquid content) of the body which ultimately leads to utklesha (aggravation of dosha for removal).[verse 96-97]
I. Action as a solvent
Fats acts as good solvent for many metabolic wastes and it enters the cells easily because cell membrane is made up of phospholipids. Compared to other non-unctous substances, fat materials stays in the body for a stipulated period without causing any harm and also possesses better permeability. The large quantity of fats administered before purification therapies do not undergo digestion and metabolism cycle because the sneha is intended to increase and channelize dosha towards koshtha.
According to Sushruta, the disease occurs due to dislodgement of vitiated doshas in the channels during their circulation in the body. [Su.Sa.Sutra Sthana 24/10] Sneha administered internally reaches microchannels and acts as a solvent to remove the obstruction by dissolving doshas in it, resulting in the removal of obstructions in microchannels, which is one of the important steps in the treatment.
II. Increase in the apyamsha (liquid content) of the body
This particular phenomenon should be understood regarding vriddhi i.e. increase in the apyamsha i.e. liquid content of the body. This leads to utklesha and can be called as transient increase in rasa (body fluids) and kleda (moisture). Sneha has the predominance of apa mahabhuta, which is corroborated by the specific qualities. [Cha.Sa.Sutra Sthana 22/15], [A.H.Sutra Sthana 1/11] and it is hydrophilic in nature. After proper snehana, all the cells of body become completely saturated with fats. Then the fat material comes out of the cell to extra-cellular fluid by osmosis. So, due to the aqueous properties of sneha and liquefied waste brought from the tissues, the levels of fatty acids etc. increase in the blood resulting in the high plasma volume. To keep up the equilibrium of the normal plasma, the extra amount of liquid from it, reaches the koshtha for excretion. This is called as anu pravana bhava. Later on when emetics or purgatives are administered, this increased amount of the body fluids are evacuated by which the vitiated doshas and in-excreted malas also expelled out resulting in the radical cure of the disease. By the combined effect of oleation and sudation, excessive increase of dosha liquification of dosha, digestion of dosha, opening of micro-channels and control of vata occurs so that, the doshas come to the kostha by Anupravana Bhava, then they are expelled out through nearest route by proper shodhana karma. [Cha.Sa.Sutra Sthana 28/33]
Sadya snehana (instant oleation) and salt with fats for early oleation
Instant oleation is required in some conditions requiring immediate purification therapy. In exacerbation of asthma sadya snehana is done and vamana is performed to remove avarana (obstruction) by kapha. Salt is having hygroscopic nature, thus when consumed with fats it increases moisture content in the body, that eventually results in early oleation.[verse 89-98]
Common method followed for oleation purpose before purification therapies
Practically approximately 30 ml of sneha is administered on first day and based upon duration required for its digestion the dose of sneha to be administed is decided, which is the dose of sneha consumption on last day. For e.g. if a hard bowel person gets appetite after 2 hours of 30 ml sneha drinking and requires medium dose oleation (sneha dose which is digested in 12 hours) then the dose on last day will be approximately 180 ml, which is achieved by gradually increasing doses of sneha in seven days.

Scope for further research
- To improve palatability of fats, scientific research on the alternative methods of consumption i.e vicharana must be carried out and the number of vicharana should be increased based upon contemporaneous food preparations.
- There is a wide scope in research regarding changes in the properties of fats when boiled with other substances i.e Samskara.
- Therapeutic effects of oleation with fats used today should be ascertain clinically so that they can be accepted as medicinal sneha.
- Combination of fats is an area least evaluated and has scope for improvement in fat properties.
- Research is needed for standardization of dose and gradation of oleation or unctuousness.
- It is important to study effect of instant oleation (Sadyo snehana), in large dose (Avapeedaka Sneha), processed fats (Avartita Sneha) and administration after meals (Auttara bhaktika Sneha).
