The dried aerial part of Equisetum hyemale (Equisetaceae). Neutral, sweet and bitter, entering the Lung and Liver channels. Disperses wind-heat and removes superficial visual obstruction from the eyes. A key herb for red eyes with pterygium; also stops bleeding for hemorrhoidal and intestinal bleeding.
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）木贼与麻黄同形同性，故亦能发汗解肌，升散火郁风湿，治眼目诸血疾也。
