How do you you get poison in your finger?

Poison can enter your finger through various means, such as a puncture from a poisonous plant or animal, like a thorn or a sting from a venomous insect. It can also occur if you handle toxic substances, such as certain chemicals or plants, and then touch a cut or an open wound. Additionally, if you have a pre-existing infection, certain toxins can enter the bloodstream through those pathways. Always exercise caution when handling unknown plants or substances to avoid potential poisoning.
