Traditional Uses

In TCM practice, Qian Niu Zi is traditionally used in small doses within classical formulas, often stir-fried before use to moderate its nature. It is traditionally associated with promoting bowel movement and draining excess water accumulation, and is commonly paired with herbs such as Da Huang or Gan Sui in historical prescriptions. Because of its potency, it has traditionally been used briefly rather than as a daily tea, and always under the direction of a qualified practitioner.
