Camphor oil has been traditionally used in various cultures for skin ailments, including rashes and hives. Its use is rooted in folk medicine, particularly in South Asia and China, where camphor is applied topically to relieve itching, irritation, and inflammation associated with minor skin eruptions. The cooling sensation provided by camphor is thought to distract from itchiness, offering symptomatic relief. Some over-the-counter balms and ointments for skin irritation contain low concentrations of camphor (generally less than 11%) for this purpose. However, scientific validation for camphor oil's efficacy in treating rashes and hives is limited. Most studies on camphor focus on its analgesic and antipruritic (anti-itch) effects, often in combination with other ingredients such as menthol. The mechanism relates to its action as a counterirritant, stimulating nerve endings to reduce sensation of pain and itching. There is little to no robust clinical evidence specifically supporting its use for hives (urticaria) or allergic rashes. Furthermore, improper use or application of concentrated camphor can cause skin irritation or toxicity, particularly in children. In summary, while camphor oil's use for rashes and hives is primarily traditional and widely practiced in folk medicine, scientific support is modest and indirect at best. Caution should be exercised, and it is not a first-line, evidence-based treatment for these conditions.
