Function：
1. Menthol can stimulate the cold sensory receptors of human skin and mucous membranes, bring a cool feeling and relieve pain and discomfort
2. Menthol has a good relieving effect on skin itching.
3. Menthol has certain anti-inflammatory and antibacterial effects.
4. Menthol is volatile and its odor can stimulate the mucous membrane of the respiratory tract and reduce mucous membrane congestion and edema.
Application：
1. Menthol is contained in many topical pain-relieving and anti-itching ointments and oils.
2. In some oral drugs, menthol is used as an auxiliary ingredient to improve the taste and odor of the drug. For example, in some cold and flu medications, menthol can help relieve sore throats, coughs and nasal congestion.
3. Menthol is the main flavor ingredient in mint-flavored candies and chewing gums; it is also used in mint tea, refreshing beverages, mint-flavored yogurt, ice cream, and so on.
5. Menthol is a common ingredient in oral care products such as toothpaste and mouthwash. It provides a refreshing cool taste and also has some antibacterial properties that help prevent oral diseases and maintain oral hygiene.
6. In skin care products (e.g. creams, lotions, masks), menthol can provide a cooling sensation. In hair care products (e.g. shampoos, conditioners), it can stimulate the scalp and promote blood circulation, and its cooling sensation can alleviate scalp itching and other uncomfortable symptoms.
7. Menthol is an important raw material for the preparation of various flavors. It can be used to blend edible flavors, such as for the production of mint flavored seasonings, baked goods flavors, etc.; can also be used to blend daily flavor, such as in perfumes, air fresheners and other products.
