Production method and use
Production method	Menthol can be purified from natural peppermint crude oil or synthesized. The aboveground part (stem; Twig; The essential oil obtained by steam distillation is called peppermint crude oil, and the oil yield is 0.5-0.6. There are many ways of synthesizing thin synthetic brain. Both menthol and racemic menthol can be used as toothpaste. Perfume; An odorant used in beverages and sweets. In medicine, it is used as a stimulant, acting on the skin or mucous membranes, and has a cooling and itching relief effect. It can be taken internally as an antiseptic for headache and nose; Pharynx; Laryngitis, etc. Its esters are used in fragrances and medicines.
