Back Then: [Wintergreen] boiled in wine and water and given to drink to them that have any inward ulcers in their kidneys or neck of the bladder, doth wonderfully help them; it stayeth also all fluxes, whether of blood or humours, [such] as the lask, bloody flux, women’s courses, and bleeding of the womb, and taketh away any inflammation rising upon pains of the heart.
– The English Physician, Nicholas Culpeper, 1652
And Now: Oil of wintergreen, now obtained by distillation of the leaves, contains methyl salicylate, similar to aspirin, which is a longstanding treatment for cardiovascular conditions including heart attacks, acting as an anti-inflammatory and blood thinner.
