Menthol is an organic compound, more specifically a monoterpenoid, made synthetically or obtained from the oils of corn mint, peppermint, or other mints. It is a waxy, clear or white crystalline substance, which is solid at room temperature and melts slightly above.
The main form of menthol occurring in nature is (−)-menthol, which is assigned the (1R,2S,5R) configuration. Menthol has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation. Menthol also acts as a weak κ-opioid receptor agonist.
Menthol is a substance naturally found in mint plants, such as peppermint and spearmint. It gives a cooling sensation and is often used to relieve minor pain and irritation. Menthol is added to products as a flavoring including cough drops, beverages, gum and candy. However, none of these products are smoked or inhaled when used. Tobacco companies on the other hand, are using this natural plant in cigarettes and other electronic cigarettes devices.
