The chapter Rasa Vimana deals with rasa and dosha, since rasa is the primary trigger for the action of drugs on doshas. 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 doshas. For example, if a person is consuming kshaar (alkali) and lavana (salt) for a long time, he is advised to decrease the quantity gradually to prevent the effect on doshas. 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.

The chapter [[Rasa Vimana]] deals with ''rasa'' and ''dosha'', since ''rasa'' is the primary trigger for the action of drugs on ''doshas''. 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 ''doshas''. 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 ''doshas''. 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 doshas. 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), ghrit (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, ghrit 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.
