Wintergreen is a native to North American. It is used for aches and pains and to help to breathe while hunting or carrying heavy loads. It is a small evergreen herb which grows up to 15cm (6
in) high, with slender stems, leathery serrated leaves, and drooping white flowers, followed by fleshy scarlet berries. Menthyl salicylate is the principal constituent of this plant and has been
incorporated in liniments and ointments for muscular skeletal problems. Ingesting menthyl salicylate even in small amounts may result in fatal poisoning.
