6. Potency, Post-Digestive Effect and Special Action
Taste is only the first layer. Ayurveda describes three more properties that explain exceptions — why honey is sweet yet reduces Kapha, or why ginger is pungent yet does not aggravate Pitta as much as chilli.
| Property | Meaning | Types | Examples | |
|---|---|---|---|---|
| Virya (potency) | The heating or cooling energy a food releases | Ushna (heating), shita (cooling) | Heating: ginger, sesame, mustard, curd, jaggery. Cooling: milk, ghee, coconut, fennel, coriander | |
| Vipaka (post-digestive effect) | The effect after digestion, mainly on elimination and tissues | Madhura (from sweet and salty), amla (from sour), katu (from pungent, bitter, astringent) | Ginger: pungent taste but sweet vipaka — gentler than chilli. Rice: sweet vipaka — nourishing | |
| Prabhava (special action) | An effect that cannot be explained by the other properties | Unique to the substance | Honey reduces Kapha despite its sweet taste; ghee cools yet kindles agni |
| Food | Rasa | Virya | Vipaka | Net effect | |
|---|---|---|---|---|---|
| Ghee | Sweet | Cooling | Sweet | Pacifies Vata and Pitta; kindles agni (prabhava) | |
| Honey | Sweet, astringent | Cooling | Pungent | Reduces Kapha; never heated | |
| Curd | Sour | Heating | Sour | Pacifies Vata; aggravates Pitta and Kapha | |
| Buttermilk | Astringent, sour | Heating (mild) | Sweet | Digestive; balances Kapha and Vata | |
| Fresh ginger | Pungent | Heating | Sweet | Kindles agni; pacifies Vata and Kapha | |
| Turmeric | Bitter, pungent | Heating | Pungent | Balances all three in culinary amounts | |
| Amla | Five tastes (mainly sour) | Cooling | Sweet | Pacifies all three — the great rasayana | |
| Moong | Sweet, astringent | Cooling | Pungent | Light; balances all three when cooked with ghee | |
| Jaggery (old) | Sweet | Heating | Sweet | Warming sweetness for winter | |
| Rock salt | Salty | Cooling (mild) | Sweet | The best salt in Ayurveda; less heating than sea salt |
