1. Noun, singular or mass Another way the potency of curare is tested is by shooting the poison into a frog and seeing how many times it hops before the frog stops moving. 2. Adjective Until curare disintegrates, the nerve cannot trigger the muscle to act and the muscle stays paralyzed. 3. Verb, base form “Curare” originates from the South American name for arrow poison, from the word, "ourare" or “woorari.” Aboriginal people still produce curare the way it was first documented in the 14th century.
