Pharmacology and Application of Camphor

Camphor (C₁₀H₁₆O), a white crystalline solid with enantiomeric R and S forms, is a terpene historically obtained from the heartwood of the Cinnamomum camphora tree by steam distillation. It has a long history of application in traditional medicine across cultures for its characteristic cooling sensation and diverse array of pharmacological activities. Camphor has been known to have antipyretic, antibacterial, antifungal, antiviral, antioxidant, antiinflammatory, and antitumor activities, and serves as a skin penetration enhancer too. Camphor has been widely used to treat minor conditions like pain, irritation, inflammation, congestion, and infections. In recent studies, camphor has shown promising uses outside what has traditionally been known. Some of the Cinnamomum camphora components have proven to be anti-mutagenic against other human cancer cell lines, differentiating between cancer and healthy cells without harming the latter. It is also of increasing interest for the possible treatment of severe ailments such as cancer and diabetes. The compound is biosynthetically similar to alpha-pinene, which is a product of catalytic reactions, indicating its chemical importance even further. This review of the literature is intended to investigate the past and present applications of camphor, paying particular attention to its use in general health cures and future medical studies. In addition, it suggests further scientific examination of camphor's impacts on neurodegenerative and memory disorders, hopefully to unleash novel therapeutic uses. With this review, we hope to bridge ancient knowledge with contemporary pharmacology and stimulate additional studies into this useful natural compound.
