Camphor oil is a colorless or white crystalline substance that is extracted from the wood of the camphor tree or other plants in the Cinnamomum family. It has a strong, pungent, and medicinal aroma that is easily recognizable. The oil is commonly used in aromatherapy and is believed to have a number of therapeutic properties, such as being an anti-inflammatory, antimicrobial, and pain relieving. It is also used as a decongestant, and in inhalants, liniments, and ointments to relieve pain and itch. Additionally, camphor oil can be used to freshen the air, and repel moths, and insects. It should not be used in high concentrations or ingested.
