Kochiae Fructus (Kochia scoparia (L.) Schrad.)

Nature and flavour. Acrid, bitter, cold; Kidney and Bladder systems.

Classically described as clearing damp-heat, promoting urination and relieving itching. It is one of the herbs the classical texts reach for in itchy skin eruptions attributed to damp-heat, and it is used both internally and as an external wash — the external use is the better-attested of the two.

性味归经。辛、苦，寒；归肾、膀胱经。

传统记载为清热利湿、利尿通淋、止痒。古籍用于湿热所致的皮肤瘙痒、风疹湿疹，既可内服亦可煎汤外洗，其中外用的记载更为充分。

Classical category · no formulas, no dosages, no herb-drug combinations are given.
Safety. Cold in nature; classically avoided where there is no damp-heat and in cold deficiency of the Spleen and Stomach. Avoid in pregnancy and breastfeeding — reliable human safety data are lacking. Allergic skin reactions are reported with the plant, and external use can irritate already broken skin; widespread or weeping rashes, or itch with fever, call for medical assessment rather than repeated washing.

性寒，传统列为无湿热及脾胃虚寒者不宜。孕期与哺乳期避免使用 —— 人体安全性数据不充分。有该植物引起过敏反应的报告，外用于已破损的皮肤亦可能刺激。范围广泛或渗液的皮疹、伴发热的瘙痒应当就医评估，不宜反复外洗自行处理。
