Heat, Burning, Inflammation, Acid. Virya – Potency, Vigor, Semen.

Potency or action (warming or cooling). Virya has two meanings depending on context; the other is strength, although this is a less common definition. Sweet, bitter and astringent
rasas (tastes) have a cool virya and generally pacify pitta and decrease agni. Pungent, sour and salty rasas have a warm virya and generally pacify vata and kapha and increase agni.
