Curare (/ kʊˈrɑːri / or / kjʊˈrɑːri /; kuu-RAH-ree or kyuu-RAH-ree) is a common name for various alkaloid arrow poisons originating from plant extracts.
Curare is the name given to various highly toxic substances used by certain indigenous tribes in South America to poison their hunting arrows. Curare is also the name given to the plants that produce the toxic substances. Curare paste was applied to arrowheads and used to kill prey when hunting.
Curare is a drug belonging to the alkaloid family of organic compounds, derivatives of which are used in modern medicine primarily as skeletal muscle relaxants.
Historically the curare plant was used to poison and kill people and animals. Curare is full of secondary metabolites called alkaloids. The type of alkaloid that curare possesses is called D-tubocuraine (C 37 H 41 N 2 O 6+). Which acts as a neurotoxin that shuts down a nervous system.
