The dried rhizome of Picrorhiza scrophulariiflora (Scrophulariaceae). Cold and bitter, entering the Liver, Stomach, and Large Intestine channels. Abates vacuity heat and eliminates gan-accumulation fever; also clears damp-heat. Despite sharing 'Huang Lian' in its name, it is botanically unrelated to Coptis and focuses on clearing vacuity heat rather than draining repletion fire.
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.
