curare (kyo͝orär`ē), any of a variety of substances originally used as arrow poisons by Native South Americans in hunting and in warfare. The main active substance of curare, tubocurarine, is an alkaloid extracted from Chondodendron tomentosum, Strychnos toxifera, and other plant species. The poison produces muscle paralysis by interfering with the transmission of nerve impulses at the receptor sites of all skeletal muscle. Muscles with many nerves, such as eye muscles, are affected first. In recent years curare has been put to medical use. When given in small quantities with general anesthesiaanesthesia
[Gr.,=insensibility], loss of sensation, especially that of pain, induced by drugs, especially as a means of facilitating safe surgical procedures. Early modern medical anesthesia dates to experiments with nitrous oxide (laughing gas) by Sir Humphry Davy of England

Curare is also used to relieve spastic paralysis, to treat some mental disorders, and to induce muscle relaxation for the setting of fractures.Curare (from Carib kurari), a mixture of condensed extracts from plants of the genera Strychnos, Chondodendron, and other South American groups. Upon entering the blood, curare blocks the transmission of neural impulses from the motor nerves to the skeletal musculature, causing muscular relaxation. Curare was used for centuries by natives of South America as an arrow poison. It contains a large number of alkaloids of the curarine group. Curariform agents are used for therapeutic purposes. curare[kyü′rä·rē] (organic chemistry) Poisonous extract from the plant Strychnos toxifera containing a mixture of alkaloids that produce paralysis of the voluntary muscles by acting on synaptic junctions; used as an adjunct to anesthesia in surgery. curare, curari1. black resin obtained from certain tropical South American trees, esp Chondrodendron tomentosum, acting on the motor nerves to cause muscular paralysis: used medicinally as a muscle relaxant and by South American Indians as an arrow poison 2. any of various trees of the genera Chondrodendron (family Menispermaceae) and Strychnos (family Loganiaceae) from which this resin is obtained curareenUK
curare [koo-rah´re] any of a wide variety of highly toxic extracts from various botanical sources, including various species of Strychnos, a genus of tropical trees; used originally as arrow poisons in South America. A form extracted from the shrub Chondodendron tomentosum has been used as a skeletal relaxant" >muscle relaxant.cu·ra·re (kū-rah'rē), An extract of various plants, especially Strychnos toxifera, S. castelnaei, S. crevauxii, and Chondodendron tomentosum, which produces nondepolarizing paralysis of skeletal muscle after intravenous injection by blocking transmission at the myoneuronal junction; indigenous South American hunters of the Amazon and Orinoco regions use arrowheads dipped in curare; curare is used clinically (for example, as d-tubocurarine chloride, metocurine iodide) to relax muscles during surgery. Often classified by the types of vessels in which hunters stored it (for example, pot curare). Synonym(s): arrow poison (1) [fr. urarr, Tupí (an indigenous S.

It was used as an arrow poison called ‘woorara paste’. Curare acts at the junction between nerves and muscles and produces complete paralysis of all voluntary movement without having any effect on consciousness. See also CURARINE.curare a paralysing poison originally extracted from the root of Strychnos toxifera by South American Indians and used on arrowheads. Nowadays it is a valuable source of drugs. Its action in paralysis is to prevent ACETYLCHOLINE depolarizing the postsynaptic membrane, particularly at nerve/ muscle junctions, thus preventing the passage of the nerve impulse and so rendering the victim immobile.cu·ra·re (kyū-rah'rē) An extract of various plants that produces nondepolarizing paralysis of skeletal muscle after intravenous injection by blocking transmission at the myoneuronal junction; used clinically to relax muscles during surgery.
