What is methol?

Menthol is a white crystalline compound that is derived from peppermint or other mint oils. It has a strong, minty odor and is used in a variety of consumer products, including cough drops, toothpaste, and mouthwash. Menthol is also used medicinally to alleviate symptoms such as sore throat, headache, and muscle pain. It works by producing a cooling sensation that numbs the affected area and reduces inflammation. However, it can also cause side effects such as skin irritation, allergic reactions, and respiratory problems if ingested or inhaled in large amounts. Menthol is also sometimes used as an additive to cigarettes to enhance the flavor and cooling effects of smoking.
