Let me put it to you this way. Everyone knows that salicylic acid (originally derived from willow bark) is a precursor to aspirin that is effective as a pain killer, fever reducer, and anti-inflammatory. https://en.m.wikipedia.org/wiki/Salicylic_acid and https://www.ehs.com/2015/07/salicylic-acid-safety-tips-hazar...

But salicylic acid is also used in skin care products like wart remover.

Here's a wart remover product for dogs and horses, which contains salicylic acid as an active ingredient: https://www.chewy.com/creative-science-wartsoff-wart-dog/dp/...

If, the next time you have a fever, you reach for the dog/horse wart remover... I'm gonna call that "dog wart remover" regardless of the fact that it contains an ingredient that is used to treat fevers in _humans_
