Birch and Wintergreen essential oil have 98% the same chemistry and smell almost identical, but wintergreen has a stronger aroma being more fruity, fresher, greener, and sweeter smelling. What makes them chemically the same is that they share a key ingredient called methyl salicylate, and they are the heaviest essential oils known to date. Each plant is 98% esters, which turn into methyl salicylate after acetylation from the fermented fresh leaves in warm water induces an enzymatic reaction to free the glycoside bound methyl salicylate.
Wintergreen was traditionally used for its key ingredient methyl salicylate, which was used as food flavouring for confections, non-alcoholic drinks, chewing gum, and toothpaste. It has also been used by the perfume and pharmaceutical industry but is now replaced by a cheaper synthetic alternative. It has a long history of use by Native Americans as a pain reliever and it is used in the form of teas, baths, and ointments. Methyl salicylates are aspirin like compounds.
Wintergreen grows in open woods, moist soil and underneath evergreens. The creeping stems send up erect branches 2-6 inches high. Alternate oval leathery leaves with serrate margins hold nodding white waxy flowers near the top of the stem. It blooms anywhere from May to September. Gaultheria fragrantissima from the Himalayas, Sri Lanka, Malaysia and East Asia is a different species but it is used in the same way and has the same chemistry too.
