Tubocurarine chloride is a mixed antagonist of nicotinic neuromuscular acetylcholine receptors, used to paralyse patients undergoing anaesthesia. It is one of the chemicals that can be obtained from curare, itself an extract of Chondrodendron tomentosum, a plant found in South American jungles which is used as a source of arrow poison. Native indians hunting animals with this poison were able to eat the animal's contaminated flesh without being affected by the toxin because tubocurarine cannot easily cross mucous membranes and is thus inactive orally.
