Hello, borneol, also known as borneol, also known as dipterocarp in ancient times, is a processed crystallized product of dipterocarp resin from the evergreen tree Dipterocarpaceae and is one of the commonly used traditional Chinese medicines. Natural borneol can be divided into dipterocarp and moxa. The latter is the crystal extracted from the leaves of the Asteraceae plant. Dipterocarp is the authentic product of borneol, and its main component is borneol. Synthetic borneol is mainly synthesized by chemical processing using camphor and turpentine as the main raw materials. In addition to borneol, it also contains a large amount of isoborneol, which is the epimer of borneol. Natural borneol mainly contains borneol, while synthetic borneol mainly contains borneol and isoborneol.
