Rating (out of 5): 1

Japanese camphor (Cinnamomum camphora) has a long history of use in traditional medicine systems, particularly in East Asia, as a remedy for various minor ailments, including skin irritations and itching. In the context of itching ears, camphor is sometimes included in topical ear preparations, primarily in the form of camphor oil or ointments. The rationale for its use is based on its cooling sensation and mild local anesthetic properties, which can temporarily distract from the itch by stimulating nerve endings and producing a sensation of relief. Historical texts and traditional pharmacopeias document the use of camphor as a counterirritant and antipruritic (anti-itch) agent. However, there is limited scientific validation for the efficacy or safety of camphor specifically for itching ears. Most modern clinical guidelines do not recommend camphor for otic (ear) use due to potential risks, such as irritation or even toxicity if misapplied. The evidence for its effectiveness remains largely anecdotal and rooted in tradition rather than rigorous clinical research. Thus, while traditional practices support the use of Japanese camphor for itching ears, evidence from well-controlled scientific studies is lacking, and caution is advised due to potential adverse effects, especially if the ear drum is perforated or with prolonged use.
