Traditional Uses

In traditional Chinese medicine, Huang Yao Zi has historically been used in decoctions and external washes, traditionally associated with clearing heat, resolving phlegm, and supporting healthy thyroid function in classical practice. It was often prepared alone or combined with other herbs according to practitioner direction. Because the raw bulb is considered potentially toxic, traditional texts emphasize careful processing and professional supervision rather than self-directed use.
