Camphor is a compound found in several plants, but it is most purely found in the camphor tree. It can be highly toxic when taken internally or allowed to penetrate into the body, so it is most typically used externally and as an aromatic for opening the lungs, easing asthma, and the discomfort associated with sprains, chest pain, arthritis, and sinus congestion.
