By\nIngrid Petres\n \nNever use wintergreen oil internally!!!\nIf using wintergreen externally properly dilute (1-2 drops per ounce of carrier)!\nAvoid use on children, pets, pregnant women, or broken skin\n \nCommon name: Wintergreen\nLatin Binomial: Gaultheria procumbens\nFamily: Ericaceae\nOther common names: Teaberry, Checkerberry, Mountain Tea\nPart used: leaves\nProduction method: Wintergreen essential oil is steam distilled from the leaves of the plant following maceration in warm water. Methyl salicylate, the main chemical constituent of the oil, is not present in the plant until formed by enzymatic action from a glycoside within the leaves as they are macerated in warm water. \nCountry of Origin: Native to North America, mainly Northeast USA and Canada.\nTypical Constituents: The essential oil is nearly 98% methyl salicylate, but may also contain triacontane, formaldehyde, gaultheriline and varies other aldehydes, ketones, and alcohols. Birch essential oil’s chemical makeup is nearly identical to wintergreen’s and can therefore be used interchangeably. Most wintergreen and birch oil on the market today is actually synthetically produced methyl salicylate, preferred by the food industry as a cheap flavoring but not by aromatherapists who look for the best available natural product with all its constituents intact.\nDescription of oil: Wintergreen essential oil is pale yellow or pinkish yellow in color. The smell is sweet, and fresh like mint. \nDescription of plant:Wintergreen is an evergreen shrub with white bell-shaped flowers and leathery, oval, slightly toothed leaves. Both its leaves and red, berry-like fruit are edible. \nHistory, Folklore and Myth: Wintergreen has been used ritually for hex breaking, protection and healing. \nProperties and uses:Methyl salicylate is formed when salicylic acid reacts with methanol. You might already know that aspirin (acetylsalicylic acid) is formed from salicylic acid and acetic acid. The chemical is beneficial to the body’s ability to manage pain and inflammation. The oil’s high concentration of methyl salicylate make it extremely analgesic, antispasmodic, and anti-inflammatory. It is mainly used for headache, arthritis, sore muscles, sciatica, and cramps. The oil should only be used topically and in very low dilution, if at all. Avoid use on pregnant women, children, or broken skin. \n * Antitussive\n* Antiseptic\n* Astringent\n * Carminative\n * Emmenagogue\n * Hepatostimulant\n * Galactagogue\n \nThe oil is also used as a flavoring for candies, sodas, toothpaste and gum in a dilution of no more than .04%. \nPrecautions and contraindications:\nNever use wintergreen oil internally!!!\nIf using wintergreen externally properly dilute (1-2 drops per ounce of carrier)!\nAvoid use on children, pets, pregnant women, or broken skin.\nNumerous cases of methyl salicylate poisoning have been reported, with a 50-60% mortality rate. Ingesting as little as 4 ml has been known to be fatal.\nOther interesting information: It is believed that the wintergreen plant produces a pheromone to help it protect itself and its colony when attacked by pathogens such as the tobacco mosaic virus. The pheromone released by the plant may attract helpful insects as well as warn other members in the colony of potential danger.This organic ester known as methyl salicylate is also produced by enzymatic reaction when the plants leaves are macerated in warm water.\nWintergreen oil is also commonly used in printmaking as a solvent. \n \n *\nBibliography:\nArctander, Steffen.
