Trishna and pipasa are two commonly used words denoting desire for water, the difference between the two is, trishna is pathological and pipasa is physiological. Generally, desire for water is physiological process to maintain fluid balance but if dosha are vitiated then they can lead to excessive thirst and can produce trishna, a disease in which person constantly craves for the water. Beside independent disease, trishna or thirst is also seen as prodromal symptom, clinical feature, complication, poor prognostic sign etc. in various clinical conditions. In this chapter, etiological factors, premonitory symptoms, pathogenesis, clinical features and complications of trishna as a disease are discussed.
‘Water is not necessary to life but rather life itself’ – This quotation describes importance of water in our life. Water is the most abundant constituent in the body, comprising approximately 50% of body weight in women and 60% in men. It is crucial for survival as it performs various functions. It transports nutrients to the tissues, removes metabolic waste products, detoxifies body elements, regulates body temperature, maintains pH, electrolyte balance etc. and homeostasis of body. In normal physiological process, certain amount of fluid is lost continuously. If this fluid balance is not maintained then, both acute and chronic fluid deficits may lead to number of adverse health outcomes. Even modest fluid deficits may precipitate adverse events, especially in young children, in the frail elderly and in those with poor health. Fluid balance in body is maintained via thirst, a feedback-controlled variable, regulated acutely by central and peripheral mechanisms. Thirst is physiological but when it exceeds its threshold it becomes pathological and is common in many diseases. Modern science accepts it as symptom only and have not given it as an entity of ‘disease’. Ayurveda is more comprehensive and broader in its approach. Fluid imbalance is a major cause of morbidity and mortality and considering this fact ‘thirst’ which is an indicator of fluid imbalance has been described as separate disease and not merely a symptom.
The other meaning of trishna is greed or insatiable desire for something. It can be referred that word trishna not only denotes physical craving but includes psychological desires also. In morbid thirst both body and mind crave and there are conditions like psychogenic polydypsia in which thirst is only due to mental involvement. As mind plays an important role in thirst as a disease this chapter has been named as trishna chikitsitam (or Trishna Chikitsa) not pipasa chikitsitam.
Trishna word in Ayurveda is interchangeably used for physiological as well as pathological thirst. Normally, vata and pitta are the two dosha inseparably involved in causing trishna as they have shoshana guna (property to absorb the water element) but the difference is vata absorbs the moisture by its dry property, whereas pitta does it by its hot property. Thirst is function of unvitiated pitta and clinically presents as mukha shosha (dry mouth) which occurs due to vata. So, it can be said that both dosha are inseparably involved in thirst production. When they are ‘unvitiated’, physiological thirst is produced and when ‘vitiated’ they can cause trishna. Based on etiological factor and pathogenesis involved, trishna is classified into five types – vataja, pittaja, amaja, kshayaja and upasargaja. These dosha absorb water from the saumya dhatu like rasa dhatu, udaka and kapha (tissues in which water content is more). Three more types – kaphaja, bhaktodhabhavaja (after excess eating) and kshataja (thirst produced due to external injury).
Presently we rely only on fluid and electrolyte supplementation to treat thirst. Treatment of trishna by ayurvedic principles may open newer vistas in the cases where thirst is difficult to treat. Increased mortality due to dehydration, especially in vulnerable populations, it is commonly observed during periods of abnormally warm weather. Mortality rate is high in remote areas where health care facilities are not good enough. Ayurvedic preparations mentioned in this chapter are easy to make, can be life saving where sophisticated medical care is not available. Based on Ayurvedic principles, rules regarding use of water in various diseases have been also given in this chapter.

As a result of shock/excess distress, fear, fatigue, grief, anger, extreme starvation, alcoholism, regular use of alkaline and sour substances, use of excessive salt, pungent, salty, dry and dehydrated food, emaciation due to excessive loss of basic body forming elements and emaciation due to disease, excessive use of purifactory procedures, excessive exposure to sunlight, pitta and vata get severely vitiated and dry up the watery contents of the body. These two dosha vigorously dehydrate the fluid carrying ducts and channels situated at the base of the tongue, throat, palate and kloma which causes morbid thirst in a man. Though the patient perpetually drinks water yet his thirst is not quenched. Such morbid thirst arises as a complication in the persons suffering from emaciation due to grave diseases. [4-8]

Dryness of mouth, hoarseness of voice, giddiness, burning sensation all over body, delirium, rigidity, dryness and roughness of palate, lip, throat and tongue, stupefaction, loss of concentration, protrusion of the tongue, anorexia, auditory impairment, burning sensation in vital organs and exhaustion are the symptoms of morbid thirst. Now listen carefully the symptoms of each of the five varieties of morbid thirst separately.[9-10]
Vata dominant trishna
अब्धातुं देहस्थं कुपितः पवनो यदा विशोषयति |
तस्मिञ्शुष्के शुष्यत्यबलस्तृष्यत्यथ विशुष्यन् ||११||
abdhātuṁ dēhasthaṁ kupitaḥ pavanō yadā viśōṣayati|

Vitiated vata absorbs the watery elements in the body. As a result of absorption of these fluids, the weak person gets dehydrated and consequently suffers from morbid thirst. 
निद्रानाशः शिरसो भ्रमस्तथा शुष्कविरसमुखता च स्रोतोऽवरोध इति च स्याल्लिङ्गं वाततृष्णायाः ||१२||

Lack of sleep, giddiness, dry mouth, distaste, and occlusion of the channels are the symptoms of the vataja morbid thirst. 
Pitta dominant trishna

The pitta is regarded as the thermal elements in the body which on vitiation, heats the watery elements to cause morbid thirst and person suffers from excessive burning sensation.
Bitter taste in the mouth, burning sensation in the head, cravings for cold things, fainting and yellowish discoloration of eyes, urine and feces, are the clinical features of pittaja morbid thirst.[13-14]
Trishna due to ama vitiation
तृष्णा याऽऽमप्रभवा साऽप्याग्नेयाऽऽमपित्तजनितत्वात् |
लिङ्गं तस्याश्चारुचिराध्मानकफप्रसेकौ च ||१५||

Morbid thirst, which originates from incomplete transformation or metabolism of food, is also a pittaja type as it originates from ama and pitta (pitta obstructed due to vitiated ama). Its clinical features are anorexia, flatulence and excessive salivation. 
Trishna due to depletion of body elements
देहो रसजोऽम्बुभवो रसश्च तस्य क्षयाच्च तृष्येद्धि |
दीनस्वरः प्रताम्यन् संशुष्कहृदयगलतालुः ||१६||

deho rasajo~ambubhavo rasashca tasya kShayAcca tRuShyeddhi |
dInasvaraH pratAmyan saMshuShkahRudayagalatAluH ||16||
The body is composed of watery elements and the colloidal fluids of the body are in turn composed of the aqueous elements. The loss of these watery elements induces thirst, low voice (altered voice), fainting, dryness of throat and palate. 
Trishna due to complications of other diseases
भवति खलु योपसर्गात्तृष्णा सा शोषिणी कष्टा |
bhavati khalu yōpasargāttrishna sā śōṣiṇī kaṣṭā|
jvaramēhakṣayaśōṣaśvāsādyupasr̥ṣṭadēhānām  ||17||

In a condition where person after indulging in heavy food, milk and unctuous articles, which during the digestive process cause thirst by obstructing the channels, in such condition vata and the thermal elements act as the causative factors.
Alcohol by its quality being tikshna (the property which causes sharp action and quick penetration), salty, sultry and dry, provokes pitta and vata. These two factors (pitta and vata) dry up the watery elements of the body in alcohol addicts. Just as hot sand absorbs and dries up the water poured on it, similarly relief is obtained by pouring of the cold water.[19-22]

Due to the loss of watery elements, man becomes dehydrated and dies soon due to thirst; the patients should therefore drink pure rain water mixed with honey, or any other water having similar properties that of rain water.
The water, that has slight astringent, secondary taste, which is light to digest, cool, possess good smell and taste and devoid of channel blocking quality, should be considered equal to rain water in effect though it may be terrestrial.[25-26]

The gargles of milk, sugarcane juice, jaggery water, sugar, honey, and wine prepared from sugarcane, grape wine, kokam (Garcinia cambogia) and citron fruit are beneficial in curing dryness of the palate.
The application of jambu (Syzgium cumini), Indian hog plum jujube, country willow, barks of five herbs (panchavalkal) and the herbs of panchamla group mixed with ghee over pericardial region, face are curative of fainting, giddiness and thirst.
When external application of paste prepared from pomegranate, wood apple, lodhra (Symplocos racemosa), white yam and citron or of whitish emblica myrobalans mixed with ghee and sour wheat porridge is done over head area it proves useful.
Paste prepared from moss, mud, and lotuses or with roasted paddy powder mixed with sour articles and ghee or application of wet cloth soaked in whey or sour wheat conjee or application of lotuses or of garlands of precious stones should be done. The contact of the breast and hands of resplendent and beloved women clad in wet silken garments and besmeared with cool and fragrant waters or sandal paste, proves beneficial.
The thinking of or listening to the description of Himalayan caves, woods, streams, lakes, lotuses, breezes, moonlight, and other cool things as well as of lovely cool waters- these have an allaying effect on morbid thirst.[34-39]

Kshayaja trishna is serious in nature as like kshayaja kasa (cough due to wasting), therefore this type of thirst should be treated with medications mentioned in cough due to wasting. Medications mentioned in kshatakshina and shosha are helpful.
In polydipsia due to alcoholism, a potion of wine diluted with equal amount of water mixed with sour, salt and liberal quantity of fragrant substances are advised. In thirst immediately after a cold bath, a drink of diluted wine or jaggery water is recommended. If thirst is due to abstinence from food or due to indigestion of unctuous diet, the patient may take thin medicated gruel; if the thirst is due to ingestion of heavy meal, the patient should vomit out the food.
If patient is strong enough, he may drink a dose of wine and water or warm water before vomiting and after cleaning mouth with long pepper, he may take a demulcent drink with sugar.
If the thirsty patient has good strength and he suffers from dry palate, he may drink ghee or use it in his food; if the patient is weak, he may take milk seasoned with ghee or unctuous meat juice.
The people who are extremely dehydrated and are weak can pacify their thirst immediately by milk or the cool and sweet meat juice of goat seasoned with ghee.
The thirst resulting from eating unctuous food should be quenched with jaggery water; and the thirst in a person who has fainted should be remedied by medication mentioned in murchha (fainting).[50-56]

In thirst caused by sannipata (vitiation of all dosha) tridoshaja, water cooled after boiling is beneficial.
Warm water is useful in condition like hiccough, dyspnea, acute fever, coryza, after consumption of ghee, disorders of flanks and throat, diseases caused by kapha and vata, or when the dosha are still not moving properly in the body and just after the purificatory treatment.
In anemia, abdominal disease, gulma, meha, depleted digestive power, diarrhea and splenic disorders water intake is not beneficial; but if the thirst is unbearable, the patient may drink water in less quantity.
If the patient is suffering from the above mentioned diseases and has become miserably afflicted with thirst and craving for water and if he does not get water, he may soon die or be afflicted with chronic illness then such thirsty patient may drink coriander water mixed with honey and sugar, or other medicated water which is wholesome in this condition.
If the thirst is remedied, it is facile to subdue the complication arising from it; therefore thirst should be treated first in all diseases. [57-62]

Tattva Vimarsha (Fundamental Principles)
- Morbid thirst is caused by severe vitiation of pitta and vata dosha.
- Etiological factors for trishna are vitiated vata and pitta as both dosha have absorbent (shoshaka) property which damage the rasavaha and udakavaha srotas and manifest the symptom of constant craving for water.
- Severely vitiated dosha vigorously dehydrate the fluid carrying ducts and channels situated at the base of the tongue, throat, palate and kloma leading to morbid thirst in a person.
- Constant craving for water is the cardinal symptom of pathological thirst.
- The morbid thirst is classified into vata dominant, pitta dominant, that due to vitiation of ama, due to excess depletion of body elements and as a complication of other diseases.
- Rain water is the best remedy to pacify thirst. The water, that has slight astringent taste, light to digest, cool properties, possess good smell and taste and is devoid of channel blocking quality, should be considered equal to rain water in effect though it may be terrestrial. Various recipes having same properties are used in management of thirst.
- The management principle of trishna includes rehydration with pure rain water, medicated water, external application of medicinal pastes.
- The temperature of water plays key role in the management of trishna. Hot water, normal water and cold water shall be used after proper assessment of dosha dominant condition.
- Nourishment of all body elements (dhatu) depends on ahara rasa. Rasa is predominantly apya (dominated by water element) in nature. So, diminution of rasa dhatu ultimately leads to loss of water content in body and production of trishna.
Vidhi Vimarsha (Applied Inferences )
Differentiation between trishna and pipasa
Trishna and pipasa are two commonly used terms. Trishna is pathological thirst while pipasa is physiological. Physiological thirst is relieved after adequate water intake, whereas, pathological thirst is not relieved even after repeated water intake. Both of them are due to vata and pitta dosha. In pipasa they are in balanced state while in trishna they are vitiated. Trishna is manifestation of decrease in saumya dhatu (body elements composed of predominantly water) in body rasa dhatu, rakta dhatu, lasika, kleda, meda dhatu, and urine. One common channel, udakavaha srotas regulates all the water content of the body. It is situated between palate, tongue and throat.
The root of transport channels of water are talu and kloma which have more than anatomical importance. They include the area of brain where thirst center is located and also throughout the body where the osmo-regulators are situated. They signal to higher integrative centers, where ultimately the conscious craving arises. As described in context of udara chikitsa, kloma should be understood as a physiological entity and may be compared with interstitial fluid which has definite role in pathogenesis of thirst as described in the chapter.
Fluid balance, normal quantity of water and other elements
The regulation of the volume and composition of body fluids (udaka), their distribution throughout the body, and balancing the pH of body fluids is crucial to maintaining overall homeostasis and health. The water and dissolved solutes throughout the body constitute the body fluids. Regulatory mechanisms involving the kidneys and other organs normally maintain homeostasis of the body fluids. Malfunction in any or all of them may seriously endanger the functioning of organs throughout the body.
Body fluids are present in two main “compartments”—inside cells and outside cells. About two-thirds of body fluid is intracellular fluid (ICF) or cytosol, the fluid within cells. The other third, called extracellular fluid (ECF) includes all other body fluids.
About 80% of the ECF is interstitial fluid, which occupies the microscopic spaces between tissue cells, and 20% of the ECF is plasma, the liquid portion of the blood. Other extracellular fluids that are grouped with interstitial fluid include lymph in lymphatic vessels; cerebrospinal fluid in the nervous system; synovial fluid in joints; aqueous humor and vitreous body in the eyes; endolymph and perilymph in the ears; and pleural, pericardial, and peritoneal fluids between serous membranes. The body is in fluid balance when the required amounts of water and solutes are present and are correctly proportioned among the various compartments. Water is by far the largest single component of the body, making up 45–75% of total body mass, depending on age and gender.
It may be noted that udaka has been mentioned to be present in quantity of ten anjali and this quantity is irrespective of rasa which is nine anjali in quantity and rakta is eight anjali in quantity. But this udaka acts as a replacement for rakta and rasa dhatu as and when necessary. Sweda, lasika, kapha, etc. are also jaliya (watery) entity which are closely related with udaka.
Mechanisms of fluid balance
- Osmosis is the primary means of water movement between intracellular fluid and interstitial fluid, the concentration of solutes in these fluids determines the direction of water movement. Because most solutes in body fluids are electrolytes, inorganic compounds that dissociate into ions, fluid balance is closely related to electrolyte balance. Because intake of water and electrolytes rarely occurs in exactly the same proportions as their presence in body fluids, the ability of the kidneys to excrete excess water by producing dilute urine, or to excrete excess electrolytes by producing concentrated urine, is of utmost importance in the maintenance of homeostasis. Sama anayati iti samanam is the definition of samana vayu. Samana has a seat in sweda, dosha and ambhuvaha srotas. As discussed above maintaining the pH (sami karoti) is brought about by specific ionic movement and this particular force is provided by samana vayu. It maintains the pH by maintaining a specific ratio of solutes and solvents and if this specific ratio is disturbed it leads to various diseases for e.g. a decrease in blood volume causes blood pressure to fall. This change stimulates the kidneys to release renin, which promotes the formation of angiotensin II. Increased nerve impulses from osmo-receptors in the hypothalamus, triggered by increased blood osmolarity, and increased angiotensin II in the blood both stimulate the thirst center in the hypothalamus. Other signals that stimulate thirst come from (1) neurons in the mouth that detect dryness due to a decreased flow of saliva and (2) baroreceptors that detect lowered blood pressure in the heart and blood vessels. As a result, the sensation of thirst increases, which usually leads to increased fluid intake (if fluids are available) and restoration of normal fluid volume. Overall, fluid gain balances fluid loss. Sometimes, however, the sensation of thirst does not occur quickly enough or access to fluids is restricted, and significant dehydration ensues. This happens most often in elderly people, in infants, and in those who are in a confused mental state. Even though the loss of water and solutes through sweating and exhalation increases during exercise, elimination of excess body water or solutes occurs mainly by control of their loss in urine.
- The extent of urinary salt (NaCl) loss is the main factor that determines body fluid volume. The reason for this is that “water follows solutes” in osmosis, and the two main solutes in extracellular fluid (and in urine) are sodium ions (Na) and chloride ions (Cl). In a similar way, the main factor that determines body fluid osmolarity is the extent of urinary water loss. Because our daily diet contains a highly variable amount of NaCl, urinary excretion of Na and Cl must also vary to maintain homeostasis. Hormonal changes regulate the urinary loss of these ions, which in turn affects blood volume. The increased intake of NaCl produces an increase in plasma levels of Na and Cl (the major contributors to osmolarity of extracellular fluid). As a result, the osmolarity of interstitial fluid increases, which causes movement of water from intracellular fluid into interstitial fluid and then into plasma. Such water movement increases blood volume.
- Water balance and electrolyte balance are closely linked. The body works to keep the total amount of water and the levels of electrolytes in the blood constant. For example, when the sodium level becomes too high, thirst develops, leading to an increased intake of fluids. In addition, vasopressin (also called antidiuretic hormone), a hormone secreted by the brain in response to dehydration, causes the kidneys to excrete less water. The combined effect is an increased amount of water in the blood. As a result, sodium is diluted and the balance of sodium and water is restored. When the sodium level becomes too low, the kidneys excrete more water, which decreases the amount of water in the blood, again restoring the balance. Water flows passively (by osmosis) from one area or compartment of the body to another. This passive flow allows the larger volumes of fluid in the cells and the area around the cells to act as reservoirs to protect the more critical but smaller volume of fluid in the blood vessels from dehydration.
- Function of samana vayu needs to be understood. Sweda dosha ambuvaha srotas is the seat for samana vayu. Maintaining the balance is the function of samana vayu and it is brought about by grahanati (to retain food until digested), pachati (to digest) , vivechayati (differentiating between waste and useful product) and munchati (to release waste to apana) action. Samana vayu is vital for organisms to be able to maintain their fluid levels in very narrow ranges. One set of receptors responsible for thirst detects the concentration of interstitial fluid. The other set of receptors detects blood volume. Arterial baroreceptors sense a decreased arterial pressure, and signal to the central nervous system in the area postrema and nucleus tractus solitarii. Cardiopulmonary receptors sense a decreased blood volume, and signal to area postrema and nucleus tractus solitarii as well. This explains the function of srotas sthita maruta (vyana vayu) and manas due to its satva guna helps in getting knowledge about the surrounding.
- Osmometric thirst occurs when the solute concentration of the interstitial fluid increases. This increase draws water out of the cells, and they shrink in volume. The solute concentration of the interstitial fluid increases by high intake of sodium in diet or by the drop in volume of extracellular fluids (such as blood plasma and cerebrospinal fluid) due to loss of water through perspiration, respiration, urination and defecation. The increase in interstitial fluid solute concentration causes water to migrate from the cells of the body, through their membranes, to the extracellular compartment, by osmosis, thus causing cellular dehydration.
The above mechanisms are disturbed in trishna.
Etiopathogenesis of trishna
In morbid thirst, vata and pitta dosha are predominately involved. Etiological factors aggravate either vata, pitta or both and manifest trishna. Both dosha have absorbent (soshaka) property, vata dosha by its drying property and pitta by its heating property. Therefore excess exposure to various factors in diet and lifestyles leading to dryness and heat inside the body are considered as causative factors for trishna. Some of the commonly observed factors are enlisted below:
- Dietary causes: Regular use of alkaline & sour substances, use of excessive salt, pungent, salty, dry and dehydrated food, extreme starvation, alcoholism
- Lifestyle causes: Excess exercise [Cha.Sa. Sutra Sthana 7/33], excess distress, excessive exposure to sunlight, fatigue.
- Psychological causes: Fear, grief, anger
- Iatrogenic causes: Excessive use of purification procedures, improper snehapana (administration of therapeutic medicated ghee or similar unctuous substance) [Cha. Sa.Sutra Sthana 13/71]
- Due to chronic diseases leading to emaciation and excessive loss of basic body forming elements
- Associated symptom of diseases like shotha [Cha. Sa. Sutra Sthana 18/18], pitta dominant gulma [Cha.Sa. Chikitsa Sthana 5/36], vrana [Cha. Sa. Chikitsa Sthana 25/30], udavarta [Cha.Sa.

Etio-pathological factors in thirst
Acute fall in blood pressure and/or blood volume will also stimulate thirst. 15% or more reduction in circulating blood volume is required for this effect. However, the effects are short-lived and the effect of osmolality changes on thirst is more significant.
Thus classification may be done as follows:
A. Causes of excessive thirst without excessive urination
1. Dehydration due to:
- Excessive sweating (diaphoresis)
- Large loose stools after eating foods high in fiber
- Hyperventilation due to anxiousness, certain diseases, such as pneumonia, or at high altitudes.
2. Other causes of dry mouth
Acute (sudden) causes of dry mouth:
- Eating dry or spicy or salty foods
- Breathing dry air, breathing through the mouth, snoring, smoking, chewing tobacco
- Anxiety, depression, stress
- Disorder of salivary glands (mumps, side effect of irradiation)
- Shock (hypovolemic, septic, anaphylactic)
Chronic causes of dry mouth (xerostomia):
- Oral thrush caused by fungal [candida] infection
- Disorders of salivary glands (sialadenitis, stones)
- Autoimmune diseases: Sjögren’s syndrome, systemic lupus erythematosus (SLE), systemic sclerosis, sarcoidosis (neurosarcoidosis), rheumatoid arthritis
- Parkinson’s disease
- Alzheimer’s disease
- Mouth or throat cancer
- Cystic fibrosis
Dry mouth as a side effect of medications or supplements:
- Anti-acne drugs: tretinoin
- Anticholinergics (spasmolytics): atropine
- Antidepressants: fluoxetine
- Antidiarrheals: bismuth subsalicylate, loperamide
- Antiemetics (drugs to treat nausea/vomiting): chlorpromazine, metoclopramide, ondansetron, promethazine, scopolamine
- Antiepileptics: valproate, topiramate
- Antipsoriatics: acitretin
- Antipsychotics: modafinil, phenothiazines, risperidone, indapamide
- Antivirals: ritonavir, indinavir; antiretrovirals (to treat AIDS)
- Aspirin overdose
- Beta-blockers (for heart disease, hypertension): atenolol, propranolol
- Bronchodilators (to treat asthma): theophylline, salbutamol
- Chemotherapeutics: bortezomib, cisplatin
- Muscle relaxants
- Nasal decongestants (sprays)
- Non-steroidal anti-inflammatory drugs (NSAIDs): aspirin, diclofenac, ibuprofen, naproxen
- Opiates: morphine
- Sedatives (sleeping pills: diazepam)
- Stimulants: armodafinil
- Marijuana (cannabis)
- Ecstasy (MDMA)
B. Causes of excessive thirst with excessive urination
In most cases of polydipsia, people drink water to replace water they have lost due to excessive urination caused by certain organic disorders. Individuals with primary or psychogenic polydipsia (often associated with schizophrenia) have no organic disorder, but they believe or feel they should drink a lot of fluid. This can lead to water intoxication (hyponatremia), which can be life threatening.

Principles of management
The treatment modalities intended to pacify vata and pitta dosha are applied for management of trishna. Specifically rain water, water processed with drugs having manda (mild) and sheeta (cool) properties, various medicated ghee mentioned in the text are used to manage trishna.
Various preparations used in management
Food and beverages
- Trina panchamula medicated water
Trina Panchamula contains five drugs namely kusha, kasha, nala, darbha and kandekshu. It pacifies pitta and it is indicated in trishna. In Bhaisajya Ratnavali, Shara is given in place of Nala. (Bhaisajya Ratnavali, Mutrakricharogadhikar 10)
Kusha – Desmostachya bipinnata
Kasha – Saccharum spontaneum
Shara – Saccharum munja
Darbha –Imperata cylindrical
Ikshu – Sugarcane – Saccharum officinarum
The above drugs should be taken along with water in ratio of 1:64 and then it should be reduced to half by boiling and later on filtered and used after cooling similar to Shadangapaniya vidhi as explained in Jwara Chikitsa.
- Laja sattu: Laja sattu is a thin gruel prepared from laja (parched rice) or roasted rice. It should be prepared with rain water and should be given to patient after mixing honey and sugar to it [Cha. Sa. Sutra Sthana 27/256].
- Yava medicated gruel: Yava (barley) is used in yava vatya (a gruel prepared out of one part of coarse powder of roasted yava (barley) and 14 parts of water).
- Peya is thin gruel of rice along with its solid portion (sikta). To prepare peya, 14 parts of water and one part of broken rice are taken and boiled well till all the rice particles become soft. Peya prepared with shali and koradusha (type of cereal) pacifies thirst.
- Food boiled with milk and mamsa rasa mixed with honey and sita (kind of sugar) should be given. Sita pacifies vata and pitta dosha so it is useful in patient of thirst .
- Trina panchamula, munjataka, priyala drugs should be mixed with mamsa rasa or kshira paka prepared from these should be given after mixing honey and sugar to it. All above drugs pacify pitta hence quench the thirst.
External application of shatadhauta ghrita is pitta shamaka so it should be used. Yusha is a soup prepared from pulses. Drugs which are madhura, tikta, sheeta and having jeevaniya properties, pacify pitta. They should be given to the patient for drinking as well as for external application.
Ghrita processed with drugs of madhuradi gana mentioned in Vimana Sthana 8th chapter should be used for drinking, massage and sprinkling purpose. Ghrita is best for pacifying pitta and vata.[Cha.Sa. Sutra Sthana 25/40] When processed with madhura gana drugs its property increases as it is yogavahi in nature (the one that accelerates the properties of others).
Various milk or juice of sugarcane when administered through nasal route decreases thirst. [Cha.Sa.Sutra Sthana 27/224] Following table enlists various diet recipes and medicinal formulations used in the management of trishna referred at various places.

Gandusha (filling the mouth to its full capacity with liquid without allowing its movement in oral cavity) with various sweet and sour drugs is useful in thirst. Madhura rasa pacify pitta whereas amla rasa is cold on external application and increases salivation so both have soothing effect in dry mouth. Use of amla drugs in the form of external application has also been advocated as they have cooling effect on touch. Thinking about cold things and environment is a part of psychotherapy which helps patient to combat desire of water.
Management of vata dominant trishna
All dietary formulations and drugs used in vataja trishna must have property to pacify vata. Milk and ghrita mentioned in kshayaja kasa (like dwipanchamuladi ghrita, guduchyadi ghrita, kasmardadi ghrita etc.) pacify vata dosha effectively and thus these preparations can also be used in vataja trishna.
Management of pitta dominant trishna
Water obtained after quenching of baked earth is said to be best for pacifying excessive thirst in agrya prakarana. This simple method can be clinically evaluated in patients of morbid thirst. [Cha. Sa. Sutra Sthana 25/40].
Management of amaja trishna
To treat amaja trishna, it is necessary that first ama is removed. For ama pachana drugs which increase agni can be used as well. Treatment of kaphaja chhardi can be followed as kapha nasaka treatment helps to remove ama. If symptoms pertaining to ama are seen than ama should be removed by inducing emesis and warm water should be used to increase agni to remove ama. As discussed earlier kshaya refers to emaciation of tissues. So, treatment which helps in revitalizing the tissue can be used as mentioned in kshatakshina, shosha can also be used.
Management of trishna due to madatyaya
Use of alcohol for treating thirst induced due to alcohol is example of Hetu Vipritarthakari (treatment with a substance similar to the cause).
Effect of cold water and hot water on body fluid balance
In conditions of dehydration and where pitta is dominant (Dhaha, bhrama, madatyaya etc) cold water should be given as it restores water content in body as well as pacify pitta by its sheeta guna. After boiling, water becomes free from various micro-organisms. Boiled water should be used in sannipatika diseases after cooling, such diseases are difficult to treat. In a study it was found that temperature range from 55 to 65 degree C is critical for effective elimination of enteric/pathogenic bacterial components. As all three dosha are involved we can’t use hot or cold water as they will aggravate at least one of the dosha (hot will increase pitta, cold water will increase vata/kapha) so normal water should be used.
In conditions with vata/kapha/vata-kapha dominance like hikka-shwasa (kapha vata tamako), fever of recent origin (nutana jwara in samavastha) etc. Warm water should be given. After ghrita consumption, warm water should be used as it increases absorption of ghrita. Warm water increases agni in nutan jwara.[ Cha. Sa. Chikitsa Sthana 3/144], [ Cha. Sa. Vimana Sthana 3/40]
In a study it was concluded that drinking hot fluids transiently increases nasal mucus velocity and so hot liquid is superior to cold liquids in the management of fluids in upper respiratory tract infections.
Water is major constituent and is needed for normal physiological process of the body. Any disturbance in its homeostasis will lead to production of many diseases. Some diseases occur due to water deficit whereas in many diseases water retention in the body is their main cause. According to Ayurvedic principles in such conditions water use should be minimal. Due to same reason it is contraindicated in udara. In jalodara (ascites) excessive intake of water is one of the causes.[ Cha. Sa. Chikitsa Sthana 13/45]
In pandu there is presence of hemodilution and edema so water intake should be restricted to minimal. In gulma, mandagni is main causative factor. [Cha. Sa.Chikitsa Sthana 5/112]
Excessive intake of water causes mandagni and if, water is taken in mandagni stage excessively, strength of agni decreases further . So, water is contraindicated in mandagni stage. If needed, water can be given in less quantity. Nowadays we are using bottled water frequently. So, it is necessary that we analyze properties of bottled water also. Studies have shown that chemicals called phthalates, which are known to disrupt testosterone and other hormones, can leach into bottled water over time. One study found that water that had been stored for 10 weeks in plastic and in glass bottles contained phthalates, suggesting that the chemicals could be coming from the plastic cap or liner. The bacterial count in bottled water increased dramatically, from less than 1 colony per milliliter (col/mL) to 38,000 col/mL over 48 hours of storage at 37 degrees C. Bacterial growth was markedly reduced at cold temperatures (refrigeration) compared with room temperature, with 50% fewer bacterial colonies in 24 hours and 84% fewer colonies in 48 hours. Interestingly, tap water resulted in only minimal growth, especially at cold temperatures (< 100 col/mL at 48 hours). These findings may be useful to increase public awareness and development of guidelines on storage temperature and expiration time for bottled water once it is opened and used. In a study it was suggested that various types of unfinished beverages have microorganism growth and can include food borne pathogens and bacterial toxins. This suggests that proper and judicious use of water should be done in healthy as well as diseases condition.
