How Kashaya (Herbal Decoction) Affects Vata, Pitta & Kapha

Ayurveda reads every food through the three doshas — your Ayurvedic body types. Here is how kashaya (herbal decoction)’s qualities interact with each:

vata

Kashaya (Herbal Decoction) helps pacify Vata. Its hot virya (potency) and light, dry and sharp qualities, with its bitter, astringent and pungent rasa (taste), counterbalance Vata's tendencies — which is why it traditionally suits Vata body types in regular use.

pitta

Kashaya (Herbal Decoction) helps pacify Pitta. Its hot virya (potency) and light, dry and sharp qualities, with its bitter, astringent and pungent rasa (taste), counterbalance Pitta's tendencies — which is why it traditionally suits Pitta body types in regular use.

kapha

Kashaya (Herbal Decoction) helps pacify Kapha. Its hot virya (potency) and light, dry and sharp qualities, with its bitter, astringent and pungent rasa (taste), counterbalance Kapha's tendencies — which is why it traditionally suits Kapha body types in regular use.
