Uses of menthol
Menthol is an ingredient found in many topical and oral preparations as both a flavoring, counterirritant, mild local anesthetic. It is used for minor pain and cold symptoms. Menthol is a compound derived from mint plants, typically peppermint oil. Other sources of menthol include spearmint and corn mint.
How should I take menthol?
Because menthol is available in combination products, it should be applied as directed on the packaging.
For topical preparations (e.g. oils, creams, ointments):
First, apply a thin layer of product to the affected area. Gently rub the skin to allow the product to be absorbed. Afterward, thoroughly wash your hand with soap and water.
In addition, avoid touching your eyes, mucous membranes, or any open wounds. In case some product gets into these areas, quickly rinse it with clean, running water.
For oral preparations (e.g. mouthwashes, oil, lozenges):
For mouthwashes and toothpastes, use about 20 mL of the solution or a pea-sized amount. Gently swish and gargle the mouthwash solution for 30 to 60 seconds. For toothpaste, gently brush your teeth using a toothbrush for 2 minutes. Do not swallow.
For lozenges, place one piece onto your tongue or cheek and allow it to dissolve slowly. Do not bite or chew the lozenge. In addition, avoid giving children lozenges as they mistake it for candy and it can be a choking hazard.
For oils, it may be necessary to mix the menthol in another liquid. Mix and drink the solution as directed.
