Borneol is a natural compound found in several medicinal plants, and it has been used in traditional Chinese medicine (TCM) for centuries. In the context of canker sores (aphthous ulcers), borneol appears in several classic Chinese topical formulations, such as “Bing Peng San” and “Liu Shen Wan,” which are traditionally applied to mouth ulcers and oral inflammations. Its use in these remedies is based on its reputed properties: clearing heat, reducing swelling, and providing analgesic effects.

However, there is a lack of robust scientific evidence from well-controlled clinical trials specifically validating borneol’s effectiveness for canker sores. A few laboratory and animal studies suggest borneol may have anti-inflammatory and analgesic effects, which could, in theory, help with symptoms of canker sores. Still, these findings have not been directly translated into high-quality human studies for this specific condition. Thus, while borneol’s use for canker sores is well established in traditional practice, scientific validation remains limited.

In summary, borneol is traditionally used to support the treatment of canker sores, but the evidence supporting its efficacy is primarily historical and not strongly substantiated by contemporary scientific research.
