Topical health benefits of the wintergreen plant are listed in the following sections.
Analgesic Activity of Wintergreen
Methyl salicylate is obtained from wintergreen leaves and is used topically for pain relief in inflammatory conditions. When applied to the skin, salicylates are hydrolyzed by esterases and yield salicylic acids that are present in the dermis and epidermis. This alleviates muscle and joint pain and reduces the severity of symptoms in individuals suffering from rheumatic conditions. The underlying mechanism of pain relief is the inhibition of the activity of cyclooxygenase, an enzyme that is responsible for producing inflammatory mediators modulating pain. 
Wintergreen for Acne Treatment
Acne vulgaris is commonly treated by antibiotics, however, accompanying adverse side effects and emergence of antibiotic resistance disfavor their use. Herbal liposomes containing Gaultheria procumbens extract are efficient for the treatment of acne owing to their antibacterial properties and favor the long-term release of constituents for maximum benefits.
