Dravyaguna refers to the study of medicinal properties and therapeutic uses of plants and other substances. It involves classifying substances based on their taste (rasa), quality (guna), potency (virya), post-digestive effect (vipaka), and specific action (prabhava).
In Ayurveda the action of a herbs is first considered organoleptic (an impression of the sensory organs), such as the aroma, taste, colour and flavour.
Ayurvedic practitioners use the principles of Dravyaguna to understand the qualities and effects of various herbs and substances, helping them prescribe treatments tailored to an individual's constitution and health condition.
In Ayurveda, "Rasa/ โtaste. โGuna/ quality,โ "Virya/ potency,โ and "Vipaka/โ post digestive taste are fundamental concepts used to understand the properties and effects of substances:
1. Rasa (Taste):
There are six tastes (sweet, sour, salty, pungent, bitter, and astringent). Each taste is associated with specific qualities and impacts on the doshas (Vata, Pitta, Kapha) and bodily functions.
2. Guna (Quality):
Describes the inherent qualities of substances, categorized into ten pairs of opposite qualities (heavy/light, cold/hot, unctuous/dry, dull/sharp, smooth/rough, dense/liquid, soft/hard, stable/mobile, gross/subtle, cloudy/clear).
3. Virya (Potency):
Refers to the heating or cooling effect of a substance. Substances are classified as either "ushna" (hot) or "shita" (cold). Understanding virya helps balance the doshas.
4. Vipaka (Post-digestive Effect):
Describes the long-term effect of a substance after digestion. It includes three categories: sweet (madhura), sour (amla), and pungent (katu). Each vipaka has specific effects on the body.
5. Prabhava
The specific potency of a drug is called Prabhava
These principles are crucial in Ayurveda for assessing the nature of herbs, foods, and other substances, allowing practitioners to tailor recommendations based on an individual's constitution and health condition.
