I pulled this from an aroma theropy site:
http://www.naturallydirect.net/oil-of-wintergreen-herb.html
Caution: Wintergreen oil must never be used internally, and should not be used if over the counter medications containing Methyl Sal are also being used. Only to be used for topical application only. Keep away from children as Wintergreen's candy like scent can result in poisoning. It should not be used for a prolonged period of time.
I would not recommend using it.

Methyl Salicylate = Methyl Sal = Oil of Wintergreen = Salicylic Acid, Methyl Ester. It contains ~90% salicylate by weight.
Aspirin = acetylsalicylic acid. It contains ~76% salicylic acid by weight.
Methyl salicylate (oil of wintergreen) (Salicylic adic, methyl ester) can be dangerous stuff. The Wikipedia article (via it's source) on the stuff stating that a single teaspoon contains 7 grams of salicylate is wrong, it's more like ~5.3 grams (assuming a teaspoon is 5 mL), still considerable.
Methyl Salicylate is often used internally (wintergreen lifesavers, etc). One 0.05 mL drop of methyl salicylate contains ~53 mg of salicylate (a single low-dose 81 mg aspirin contains ~62 mg salicylate). It is also used externally in pain rubs. I've seen it present at 30% in these products. It can and has been lethal via overuse in external ointments.
If 4 drops (0.2 mL) oil of wintergreen were used to make 10 mL of an eliquid, the salicylate concentration would be ~21 mg/mL. So vaping 1 mL of this (and assuming full absorption of the oil by the body) would give one about a third of an 81 mg low-dose aspirin worth of salicylate. As stated in a previous post, this represents a pretty good wintergreen hit.
The chemist in me says go for it if you like it, but try to keep it down to a few drops per 10 mL of eliquid. I suspect using too much in an eliquid would be a fairly self-limiting exercise.

Yep, that pretty much confirms it. Oil of Wintergreen in eliquids will become intolerably strong long before it becomes a health issue.
