Traditional Uses

In TCM practice, Chang Shan has long been included in classical decoctions, most famously paired with herbs such as betel nut seed and grass-leaved sweetflag in traditional formulas. It was traditionally associated with resolving phlegm accumulation and was historically used around seasonal changes. Because of its cold and acrid nature, traditional texts advise careful processing and measured use rather than long-term self-administration.
