Camphor Powder Natural
Camphor is said to have been first used as a drug in the Arabian Peninsula around AD 600, and, eventually came to be used as a sacred panacea in Greece and Egypt.
In those days, camphor was obtained only from camphor wood (this product is known as natural camphor). In the 1920's, however, a mass-production synthesis method was developed in which camphor is obtained from rosin-derived turpentine oil. Currently, virtually all camphor is produced by this synthesis process.
Therefore, camphor is categorized into natural camphor and synthetic camphor.
Natural camphor
Camphor wood is subjected to a steam distillation process to obtain camphor. Synthetic camphor
Turpentine oil originating from rosin is synthesized and processed into camphor.
