Menthol Vs. Methyl Salicylic Acid

Menthol and methyl salicylic acid are both used as ingredients in topical pain ointments. They are also used as flavorings in candies, gums and mouthwash. And they have been studied to see if they will kill ticks as well as thymol.

Origins

• Menthol is extracted from peppermint leaves. Methyl salicylic acid, otherwise known as oil of wintergreen, is derived from birch leaves.

Internal Use

• Both of these extracts can be used internally as flavoring or medicinal tincture, but only in very small doses.

Topical Use

• Menthol creates a cooling sensation in skin and muscle tissue with topical use. Methyl salicylic acid is a warming agent. They are often used together in the same pain relief ointments.

Safety

• The form of each found in topical ointments and essential oil must never be taken internally as they are poisonous. Wash your hands thoroughly after touching on ointment with these ingredients. Never let these ingredients get in your eyes.

Other Possible Uses

• These oils were tested to see if they would be effective against bovine ticks. They did not appear to have any effect on the ticks as compared to thymol (thyme oil) according to a study published by Novalino da Silviera of the Universidad Federal de Juiz de Fora.
