<div style="text-align:justify;">The word ‘Rasa’ literally means taste sensation, essence, fluid, mercury, flavours. This chapter is related with the tastes of food substance and its importance in diet related to health. [[Dosha]] and rasa are the prominent factors for the assessment of diseases and drugs respectively. There are six rasas - madhura (sweet), amla (sour), lavana (saline), katu (pungent), tikta (bitter), and kashaya (astringent). These have pacifying and provoking effect on physiological status of [[dosha]] in body. This effect of rasas on [[dosha]] is due to conjunction of rasas and [[dosha]] by virtue of their similar and dissimilar properties. Their proper use in accordance with the body constitution maintains health, otherwise they vitiate the [[dosha]] (increase or decrease) which leads to various disorders in the body. This interaction of rasa and [[dosha]] is described in details. Eight specific factors of dieting and twelve guidelines about eating food have been described in this chapter, which are of immense value for those seeking a healthy and long life. These rules set the criteria for categorizing food as wholesome or unwholesome. </div>

<div style="text-align:justify;">

The chapter [[Rasa Vimana]] deals with ''rasa'' and [[dosha]], since ''rasa'' is the primary trigger for the action of drugs on [[dosha]]. Three ''rasas'' act as either enhancers or suppressors for each [[dosha]]. Once the action of a particular ''rasa'' on a [[dosha]] is known, the effect of ''dravya'' can be predicted in the same manner and after knowing the action of [[dosha]] one can understand the disease process. Prolonged usage of certain food articles is known to vitiate [[dosha]]. For example, if a person is consuming ''kshaara'' (alkali) and ''lavana'' (salt) for a long time, he is advised to decrease the quantity gradually to prevent the effect on [[dosha]]. Typically, it is advised to take meals that have all the six ''rasas'', since that helps neutralize the effect of any particular ''rasa'' on a [[dosha]].

Thus, considering the beneficial and harmful effects of food, eight types of dietary regimen have been described in [[Ayurveda]], collectively called ''ashta ahara vidhi vishesh aayatana'', with special instructions like eating freshly prepared warm food that is unctuous, neither more or less in quantity, is suitable to the individual’s capacity to digest, is suitable to the location, and that the food is not eaten too slow or too quickly.

Another agent discussed in this chapter is drugs used in pacifying aggravated [[dosha]]. The use of a ''dravya'' (agent) in a specific scenario depends on its intrinsic ''rasa'' and ''guna'' and its effect on a [[dosha]]. In cases where the use of a food article or an agent/''dravya'' results in direct action that is well understood, is called ''prakriti samavaya''. For example, ''taila'' (oil), ''ghrita'' (clarified butter) and ''madhu'' (honey) are known to pacify [[vata]], [[pitta]] and [[kapha]] respectively.

This rule is, however, not applicable for all afflictions or agents because when a ''dravya'' is combined with another ''dravya'' in different quantity and/or of varying purity, then the outcome could be quite different than that of a basic ''dravya''. Such outcomes are known as ''vikrati visham samavaya''. Rasa, dravya, [[dosha]] and ''vikara prabhava'' are based upon these two principles.  The three ''dravyas'' mentioned earlier (''taila, ghrita'' and ''madhu'') are largely used in formulations of other drugs, as diet, or as ''anupana'' (concomitant drug). These three do not have any side effects. On the other hand, ''pippali'' (piper longum), alkaline and saline substances invariably vitiate [[dosha]] on frequent use and are advised for limited use.

After comprehending the features of a disease in terms of its etiology, prodromal features, signs and symptoms, suitability, number, predominance of morbid factor, classification, proportional variation, intensity and duration, the physician should assess carefully the features of the drugs, agents, and the constitution of the patient ([[dosha]], drugs, place, time, strength, body, constitutional dominance of one or the other [[dhatu]], diet, suitability, psyche, constitution and age) because the therapeutic interventions depend on the knowledge of the features of [[dosha]], etc. A physician having no knowledge of the features of [[dosha]] is incapable of controlling the disease. Hence O Agnivesha! For the knowledge of the features of [[dosha]], etc., we shall describe this section on ''vimana'' (specific features) [3]

To start with, we shall talk about the effects of ''rasa, dravya'' (substance), [[dosha]] and ''vikara'' (disorder). ''Rasas'', as we know, are six – sweet, sour, saline, pungent, bitter and astringent. These maintain the body in harmony if used appropriately otherwise vitiate the [[dosha]]. [4]

Three ''rasas'' aggravate one [[dosha]] while the other three pacify it. For example, pungent, bitter and astringent (''rasa'') aggravate [[vata]] while sweet, sour and saline pacify it. Likewise, pungent, sour and saline rasas aggravate pitta while sweet, bitter and astringent ones pacify it. Sweet, sour and saline ''rasa'' aggravate [[kapha]] while pungent, bitter and astringent pacify it. [6]

Whether it is an agent (generically termed ''dravya'' in Sanskrit) with multiple ''rasas'' or a disorder having afflictions of various [[dosha]], one should first critically analyze the role of each rasa or dosha individually and then determine the effect of the ''dravya'' and the disorder. [9]

But this rule is not applicable universally because in case of complex disorders (and ''dravyas'') where the effect is not exactly in accordance with the cause due to multiple causative factors operating, with differing (often conflicting) modes of operation, it is not possible to determine the effect of the ''dravya'' or the disease on the basis of the effect of individual ''rasas'' or ''doshas''.

Oil possesses the properties of unctuousness, hotness and heaviness and as such pacifies ''vata'' when used regularly. ''Vata'' possesses roughness, coldness and lightness and is thus pacified by the habitual use of oil. In the same way, ghee’s sweetness, coldness and dullness overcomes ''pitta''’s  non-sweet, hot and sharp properties. Finally, honey’s  roughness, sharpness and astringency neutralizes the effects of ''kapha''’s unctuous, dull and sweet properties. Any other substance which is antagonistic in properties to ''vata, pitta'' and ''kapha'' will similarly help in pacifying them when used regularly. [14]

Salt is endowed with hotness, sharpness, moistening, laxative, and relishing qualities and is not so heavy and unctuous. Quite like long peppers, it has apparent benefits when used properly and sparingly, but causes accumulation of ''doshas'' when used habitually or excessively. Its excessive usage causes malaise, laxity and debility in the body. The people of villages, cities, communes and districts who use it continuously are exceedingly depressed, have loose muscles and blood and low tolerance for pain. Such inhabitants as those of ''Bahlika, Saurashtra, Sindhu'' and ''Sauveera'' (countries / regions in ancient times) even take salt with milk. Moreover, such regions of the world have barren, saline soil and plants – herbs, shrubs, trees and big trees – that do not grow or are stunted because of damage by salt. Hence one should not use salt too much. Even the persons who tend to use excessive salt fall victims to untimely baldness, graying of hair and wrinkles. [18]

One should eat when the previous meal is digested because if one eats before earlier meal is digested, mixing with undigested food will vitiate all the ''dosha'' quickly. On the other hand, when one eats after the previous meal is well digested, the ''dosha'' do not get vitiated or unsettled from their natural locations, agni is stimulated, appetite is increased, entrances of the channels get cleared, eructation is pure, heart is normal, there are natural urges to pass bodily wastes and there is no obstruction to their passage, and the eaten food enhances one’s life without afflicting any ''dhatu''. [25.4]

*[[Rasa]] (taste) is one of the attributes present in [[dravya]] (substances), which can be perceived by the tongue.

**There are six ''rasas, madhura'' (sweet), ''amla'' (sour), ''lavana'' (salty), ''katu'' (pungent)'', tikta'' (bitter) and ''kashaya'' (astringent).

**There are six [[rasa]], madhura'' (sweet), ''amla'' (sour), ''lavana'' (salty), ''katu'' (pungent)'', tikta'' (bitter) and ''kashaya'' (astringent).

**Each ''Rasa'' is composed of two ''mahabhutas'' (basic elements). Madhura rasa is made up of prithvi and apa, amla rasa of prithvi and agni, lavana of apa and agni, katu of vayu and agni, tikta of vayu and akasa , and kashaya is made up of vayu and  prithvi.

*Rasas influence doshas which influence health and disease. For example: madhura, amla and lavana aggravate kapha, while katu, tikta, and kashaya pacify it. Similarly, amla, lavana and katu aggravate pitta while madhura, tikta, and kashaya pacify it. And katu, tikta and kashaya aggravate vata, while madhura, amla and lavana pacify it. Thus, three rasa aggravate one dosha, whereas others pacify it. Proportionate use of all six rasas in a diet is considered healthy practice and forms the basis of a superior satmya.

**Manifestations of panchmahabhautic constitution of dravya follows rules of cause and effect in regards to relationship between rasa, vipaka and veerya and is known as prakriti samasamaveta with an exception of vikrati visham samveta. Same rule is followed by interplay between doshas in genesis of disease.

*The effect of ''rasas'' is subdued by ''vipaka,'' which is based on them. ''Vipaka'' is of three kinds i.e., ''madhura, amla'' and ''katu''. According to Agnivesha, it is often noted that the ''dravyas'' having ''katu, tikta'' and ''kashaya rasa'' have ''katu vipaka,'' while ''amla rasa dravyas'' have ''amla vipaka'' and ''dravyas'' with ''madhura'' and ''lavana rasa'' have ''madhura vipaka.''

*''Eka rasa satmyata'' (literally, one ''rasa'' suitability) provides minimal nutrition to the ''dhatus'' of body, whereas ''sarva rasa satmyata'' provides the most nutrition. ''Sarva rasa abhyasa'' (or, all ''rasa'' exercise/habit) is a practice that helps meet all the nutrient requirement of the body. Consumption of one ''rasa dravyas'' for prolonged periods of time can create imbalances in the body. For example, ''madhura rasa'' is rich in carbohydrates and its habitual consumption may lead to excess carbohydrate and lack of other nutrients.

*Some researchers in Finland reported that significant reduction of salt from their diets played a critical role in adding 5 to 6 years to the life expectancies of the Finnish population . They also reported that hypertension is the leading cause of death in developed countries. Reduction of salt intake is recommended as a key measure in the prevention and basic treatment of hypertension both in the United States and worldwide. The Renin-Angiotensin Aldosterone (RAA) system is maximally activated when an individual is subjected to prolonged very low sodium intakes of less than 5 mmol a day. Half-maximal stimulation (or inhibition) of plasma rennin activity takes place at sodium intake levels of approximately 30 mmol a day. Sodium intake at the level of 50 mmol a day suppresses secretion of the sodium-retaining hormone, aldosterone, almost completely. The control range of the RAA mechanism is therefore in excellent agreement with the sodium amounts, which can be derived from diets comprising only of natural articles without any artificial addition of salts or other sodium compounds. These findings strongly support the view that human beings are genetically programmed to eat foods that contain sodium in amounts that are naturally present but do not contain added salt.
