Can geranium oil be used to treat prickly heat?

Geranium wilfordii (Old鹳grass) is commonly used to treat prickly heat rash; however, it should be used under the guidance of a physician.

When applied externally, Geranium wilfordii is typically used in the form of a liquid obtained from decocting the herb or as an ointment applied to the affected area. Geranium wilfordii has effects of clearing heat, detoxifying, reducing swelling, and relieving itching. For prickly heat rash caused by damp-heat, appropriate use of Geranium wilfordii may provide some relief. Provided there is no allergic reaction, using Geranium wilfordii as an adjunctive therapy may help alleviate discomfort caused by prickly heat rash.

In some cases, using Geranium wilfordii may cause local skin irritation, presenting as sensations of burning, stinging, dryness, or flaking. These symptoms are usually temporary and tend to subside gradually after discontinuation of the ointment. Additionally, there are various treatment options for prickly heat rash; besides topical medications such as Geranium wilfordii ointment, treatments such as local cold compresses, oral medications, laser therapy, and infrared therapy can also be considered.

During treatment, patients should ensure good indoor air circulation, wear breathable clothing, bathe frequently, and thoroughly dry the skin afterward to reduce skin friction and sweat accumulation, thereby accelerating the resolution of prickly heat rash.
