This frog poison is a steroid toxin, which can destroy the normal activities of the nervous system. Its main action form is that when used inside or outside the axon, curare poison can cause irreversible depolarization of the axon, reduce the range of potential action, hinder ion exchange in animals, make nerve cell membrane a poor conductor of nerve impulses, make the instructions sent by the nerve center fail to reach tissues and organs normally, and finally lead to cardiac arrest, and there is no effective first aid measure. However, the poison of poison dart frog can only work through human blood. If you don't cut your finger, the venom can only cause a rash on your finger at most, but it won't be fatal. Smart Indians all know this truth. When catching poison dart frogs, they always wrap their hands with leaves to avoid poisoning.
