Punarnava

Punarnava (Boerhavia diffusa), meaning "one that rejuvenates," is a powerful herb in Ayurveda known for its diuretic, anti-inflammatory, and detoxifying properties. Widely used for kidney health, liver detoxification, and managing water retention, Punarnava helps balance the Kapha and Pitta doshas while mildly pacifying Vata.
