Traditional Uses

In TCM practice, Qian Niu Zi has traditionally been used to promote downward movement of water and food stagnation, and the black seed is one of the two seed colors traditionally recognized for this herb. It was classically prepared by grinding into powder for inclusion in decoctions or pills, often paired with other draining herbs in traditional formulas. Because of its traditional strength, it was generally used in small amounts and avoided during pregnancy in classical texts.
