A dried powder or mass processed from the leaves of Baphicacanthus cusia, Polygonum tinctorium, or Isatis indigotica. Cold and salty, entering the Liver and Lung channels. Clears heat, resolves toxicity, cools the blood, and dissipates macules. Usually taken in pill or powder form or applied externally; not suitable for prolonged decoction.
Reference range for non-pregnant adults. Not a personalized prescription. Pregnancy, lactation, and pediatric use require specialist supervision.
Protective guidance only — when to avoid or use with caution. This block deliberately omits pregnancy, lactation, and pediatric dosing: any such use must be managed by a qualified TCM practitioner or appropriate specialist.
（时珍曰）青黛解诸药毒，小儿诸热惊痫，天行头痛寒热，煎水服之；小儿丹热，和水研服。
