The dried rhizome of Smilax glabra (Liliaceae/Smilacaceae). Neutral, sweet and bland, entering the Liver and Stomach channels. Resolves toxicity, eliminates dampness, and frees the joints. Historically the primary herb for syphilis in the Ming dynasty; now broadly used for damp-heat skin conditions and joint swelling.
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.
