Camphor is a white, crystalline substance with a strong aroma, derived from the wood of the camphor tree (Cinnamomum camphora). It has been used for centuries in traditional medicine, as well as in cooking and religious rituals. Camphor is known for its cooling properties and is often found in ointments and balms to relieve pain and itching. In addition to its medicinal uses, camphor is also used in the production of plastics, cellophane, and explosives. It can be found in some household products, such as mothballs and air fresheners. However, camphor should be used with caution, as it can be toxic in large amounts.
