Root, seed and whole plant

Root is purgative, anti helminthic and febrifuge.
The active principle-punarnavine is a diuretic chiefly acting on the glomeruli of the kidney through the heart, increasing the beats and strength and raising the peripheral blood pressure. On the cells of the tubules it exerts little or no action. On liver the action is secondary.
