"The fruits of G. procumbens, considered its actual "teaberries," are edible, with a taste similar to Candy Hearts and the leaves and branches make a fine herbal tea, through normal drying and infusion process. For the leaves to yield significant amounts of their essential oil, they need to be fermented for at least 3 days." \\ | "The fruits of G. procumbens, considered its actual "teaberries," are edible, with a taste similar to Candy Hearts and the leaves and branches make a fine herbal tea, through normal drying and infusion process.

| In G.procumbens, a major part of methyl salicylate is bound to sugars, especially to the disaccharide primeverose (6-O-β-d-xylopyranosyl-d-glucose) to form gaultherin (26mg/g plant fresh weight). Gaultherin is enzymatically hydrolyzed upon tissue disruption and methyl salicylate is released as a protective mechanism for the plant. Total salicylate content of wintergreen tissues were found (mg/g fresh weight): leaves (3.8), flowers (6.4), stems (2.2), and berries (1.4). \\ |

Decoctions of the leaves and the essential oil are used in traditional medicine "... externally as a counterirritant to treat painful muscles and joints, including rheumatism. Infusions, decoctions or small amounts of the oil are rarely taken internally, as tonic, to treat rheumatism and to relieve minor stomach upsets. Canadian Natives traditionally made a refreshing tea from the leaves...

Nowadays, synthetic methyl salicylate has largely replaced the natural product...

Methyl salicylate is also main components of the leaf oil from Gaultheria fragrantissima (94.6-97.0%) and Gaultheria yunnanensis (99%). Minor component was eg. ethyl salicylate. \\ | Methyl salicylate is also the main component of the leaf oil of Gaultheria fragrantissima (94.6-97.0%) and Gaultheria yunnanensis (99%).
