Yes. Also the active ingredient in Wart remover, though at higher concentrations (2% for stridex and 17% for wart remover). Good at melting skin I guess.
Which perhaps illustrates why it's not so good for your stomach and why, therefore, aspirin (same properties without stomach issues) was a breakthrough.
Aspirin isn't especially great on your stomach either.
It is much better. That's the point...
I would think that illustrates why willow bark tea is better than aspirin for your stomach...
Which it turns out not to be. Too much salicin can still cause stomach bleeding, says the internet.
Just want to note for the record that I wasn't making a quality claim about aspirin; just noting additional information regarding salicylic acid.
