Keywords: Wintergreen, methyl salicylate, food additives, ototoxicity, aspirin
Wintergreen is an evergreen plant usually growing under coniferous trees. It can be identified by the mint like flavor when chewing the leaves. However, wintergreen oil when ingested is ototoxic sharing the same compound as Aspirin which is methyl salicylate. Salicylate damages the hair cells in the cochlear producing tinnitus and hearing loss. Wintergreen is used in medicated creams, minty mouthwashes, and occasionally candies.
The levels of methyl salicylate in Wintergreen leaves are apparently very high. Consequently, it is unadvisable to chew or consume this plant without the risk of toxicity damaging the hearing apparatus.
Anyone with a predisposition or constitutional weakness to hearing loss or tinnitus should take precautions and read labels to avoid this possible food additive in products advertised as minty.
