Borneol is a bicyclic organic compound and a terpene derivative. The hydroxyl group in this compound is placed in an endo position. The exo diastereomer is called isoborneol. Being chiral, borneol exists as enantiomers, both of which are found in nature: d-borneol (also written (+)-borneol) and l-borneol (or (−)-borneol).

Although borneol is not an herb per se, it is nevertheless a common ingredient in many traditional Chinese herbal formulas. Borneol is actually a compound derived from dryobalanops aromitaca, a tree that belongs to the teak family. The compound is formed by tapping the trunk of the tree, then cooling the substance and allowing it to harden into ...
