“Curare” is a term that refers to a class of toxic compounds derived from certain plants, traditionally used by indigenous South Americans as arrow poison. The name is often associated with a specific type of curare known as “tubocurarine,” which acts as a muscle relaxant by blocking nerve impulses to muscles and has been used in medicine, particularly in anesthesia. In a broader sense, curare can refer to any substance that causes paralysis by affecting the neuromuscular junction.
