I know they obviously sting for some reason – not sure why though.
I’ve always had a really bad reaction to them and I was wondering why or what their exact effect was on skin
In: Biology
The leaves themselves have small almost invisible “spikes” or stings on the surface of them. These are coated in methanoic (formic) acid which is what actually hurts. The acid itself is actually extremely similar to vinegar so you should get a similar feeling pouring vinegar into dot sized cut 😀
