Varunadi Kwath

Varunadi Kwath (वरुणादि क्वाथ) is a classical Ayurvedic decoction formulation referenced in Ayurved Sar Sangrah, centred around Varun Ki Chaal (Crataeva nurvala bark). Varun is one of Ayurveda's most powerful herbs for the urinary system, particularly known for its ability to dissolve kidney and bladder stones (renal calculi).

The formulation combines Varun with Sonth (ginger), Gokhuru (Tribulus terrestris) and Passan Bhed (stone-breaker herb) — creating a synergistic combination that simultaneously dissolves urinary calculi, reduces inflammation, promotes diuresis and supports kidney function.

Varunadi Kwath is particularly effective for kidney stones, urinary tract calculi, bladder cysts and uterine diseases. Its name "Varunadi" (starting with Varun) signifies its primary therapeutic action on the urinary system.
