Don't Eat Mushrooms

Help me, please! I was lost in the woods for days. I was hungry, so I and picked some mushrooms. They tasted fine, I guess, this may have been a fatal mistake. The... mushrooms, they're tearing through me like glass. I-I don't wanna die... I need an anti-toxin. There should be a bush, I'll describe it to you. The leaves work against poisons, they're my only chance! I'm sure it's nearby... I'm just so tired now and I can hardly see... hurry, please...
