Verification of ice flakes
Borneol, originally named Longnaoxiang, was introduced to China more than two thousand years ago and first appeared in the "Record of Famous Doctors". Later on, many herbal medicines were recorded, and the name "Borneol" was used in the "Bencao Mengqi". Borneol, as a precious Chinese medicinal herb, has always been imported until modern times when synthetic Borneol was imported into China from Germany and Japan before and after the Opium War, becoming the main source of Borneol. In the 1980s, China discovered a chemical type of camphor tree (Longnao Camphor) with a high content of right-handed Longnao. Through distillation and crystallization techniques, we obtained a natural borneol product that is similar to the ancient Longnao fragrance and named it Natural Borneol.
