Can geranium herb be used to treat prickly heat?
Geranium wilfordii (Old鹳grass) can usually help treat prickly heat to some extent, but it should be used under the guidance of a physician.

Geranium wilfordii has effects of clearing heat, detoxifying, relieving dampness, and alleviating itching. In traditional Chinese medicine, it is commonly used for treating eczema, skin itching, and similar symptoms. Prickly heat rash is a skin inflammation caused by blocked sweat pores, usually due to damp-heat. Therefore, for mild cases of prickly heat without other symptoms, washing the affected area externally with a decoction of Geranium wilfordii or applying it topically in the form of an ointment may help alleviate symptoms.
When using Geranium wilfordii, follow the instructions provided or the advice of a doctor. Usually, the ointment should be evenly applied to the affected area and gently massaged until absorbed. During use, observe any skin reactions carefully, and if adverse effects occur, discontinue use immediately and seek medical attention. Although Geranium wilfordii has some therapeutic effect on prickly heat, it should not be solely relied upon to resolve all issues. While treating prickly heat, it is also important to keep the skin dry and clean, and avoid prolonged exposure to hot and humid environments.
When using any herbal remedies, personal hygiene should be maintained, and the affected area should be kept clean and dry to promote recovery.
