Sun Euphorbia Herb (Wartweed) zé qī · 泽漆

Euphorbiae Helioscopiae Herba (Euphorbia helioscopia L.)

Nature and flavour. Acrid, bitter, slightly cold; counted as toxic. Large Intestine, Small Intestine and Lung systems.

Classically described as draining water and dispersing swelling, transforming phlegm and dissipating masses, and — in external application — as dispersing swellings and killing parasites. The classical texts place it among the harsher water-draining herbs: the fresh plant yields a milky latex, and it is listed as toxic in the materia medica. In contemporary practice it appears far less often than the milder damp-draining herbs, and the traditional indications here are recorded rather than confirmed.

性味归经。辛、苦,微寒;有毒。归大肠、小肠、肺经。

传统记载为利水消肿、化痰散结,外敷则散结杀虫。古籍将其列入作用较峻的逐水一类:鲜品折断有白色乳汁,本草明确记为有毒。现代使用远少于性味平和的利水渗湿药;本条目只记录传统记载,不代表已经证实。

Classical category · no formulas, no dosages, no herb-drug combinations are given.
Safety. Listed as toxic in Chinese materia medica. The milky latex of the fresh plant irritates skin and eyes and can provoke blistering on contact; gloves are indicated when handling the fresh herb. Not for self-use, and not for internal use except under the direction of a qualified practitioner. Avoid in pregnancy and breastfeeding; avoid where the Spleen and Stomach are weak and cold. Swelling of the legs or abdomen with breathlessness, or swelling that appears abruptly, is a matter for medical assessment — oedema is not a self-managed condition.

中药文献列本品有毒。鲜品白色乳汁对皮肤与黏膜有刺激性,接触后可致红肿起疱,处理鲜药应戴手套。不作自用;内服须在有资质的执业者指导下进行。孕期与哺乳期禁用;脾胃虚寒者不宜。下肢或腹部水肿伴气促、或突然出现的水肿应当就医评估 —— 水肿不是可以自行处理的症状。
