Traditional Uses

In traditional Chinese medicine, Qing Dai has long been valued as a cold, salty heat-clearing agent. It was traditionally applied externally in powders and pastes, often combined with other herbs such as Huang Bai or Gypsum, and appears in classical external preparations. Because of its concentrated nature, it has historically been used in small amounts within compounded formulas rather than as a standalone daily herb.
