The dried whole plant of Viola yedoensis (Violaceae). Cold, bitter and pungent, entering the Heart and Liver channels. Clears heat, resolves toxicity, and disperses abscesses, especially boils and deep-rooted sores. Commonly combined with Pu Gong Ying and Jin Yin Hua in Wu Wei Xiao Du Yin (Five-Ingredient Toxin-Dispersing 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.
