Traditional Uses

In TCM tradition Huang Yao Zi is classified as bitter in flavor and cold in nature, traditionally associated with the liver and lung channels. It has historically appeared in folk formulas for resolving nodules and swellings, most often prepared as a decoction or external wash. Because the raw herb can be harsh, traditional practice pairs it with moderating herbs and uses it only under professional guidance.
