What a shitty defense mechanism

I touched some poison ivy with my hands on purpose a few days ago and nothing happened. Am I immune?

Perhaps the oils that cause an allergic reaction only incidentally trigger immune responses in humans, as opposed to being an evolved defense mechanism.

Poison ivy only releases its chemicals when adequate pressure is applied. If you squeezed it or stepped on it and then touched your boots you'd be itching

perhaps it is difficult for deer to eat and I daresay theyd be smart enough to avoid it in the future

Some people are immune. I grabbed a tree that had poison ivy growing up it as a vine which is the most potent form and didn’t get it. I also walk through it a lot with shorts and crocs no problems.

nevermind deer and other animals can eat it just fine, it evolved as an antimicrobial agent and apparently it just happens to cause irritation, sort of like capsaicin which didnt evolve to deter mammals from eating it but to stop fungus and microbes though the mechanism that capsaicin and urushiol (the chemical is posion ivy that makes you itch)
make you itch is different. The reason why mexicans and indians are better at eating spice is because those who could tolerate more spice in their food got to eat safer food whereas this selective pressure did not exist in europe as there was no spicy plants and we could just store food outside in the winter.
Or maybe god just made us that way

I’ve heard that it builds up overtime and can eventually kill you because of that.
