Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Japanese camphor (Cinnamomum camphora) has a long history of topical use in traditional Asian medicine, including in Japan and China, for a variety of skin conditions such as rashes, hives, itching, and irritation. Historically, camphor has been used in ointments and balms for its cooling sensation and its perceived ability to soothe inflamed or irritated skin. The mechanism is thought to be related to its action on nerve endings, providing a counterirritant effect that distracts from the sensation of itching or pain.

There is limited scientific evidence to directly support the efficacy of camphor specifically for rashes and hives. Most available studies and clinical data on camphor focus on its use as a topical analgesic, antipruritic (anti-itch), and as a component in products for coughs and muscular aches. Some modern over-the-counter creams and ointments include camphor for relief of itching and mild irritation, but robust clinical trials for its effect on conditions like urticaria (hives) or various rashes are lacking. Furthermore, safety concerns exist: camphor can be toxic if ingested or used excessively on the skin, especially in children.

In summary, while camphor’s use for rashes and hives is well established in traditional medicine, scientific validation is limited and evidence quality is low. Its use should be approached with caution, and it is best to consult a healthcare provider before using camphor for these conditions.
