Curare grows in the South American rainforest as a large vine in the canopy. Some Indians of South America use it as part of a poisonous mixture, called "ampi" or "curare," that they put on the tip of their arrows and darts to hunt wild game.
Curare is a plant extract that acts as a muscle relaxant and paralytic agent when it enters the bloodstream. To survive, curare needs animals to serve as hosts because it is administered as a poison to immobilize prey during hunting or as a means of defense against predators.
Curare is considered a poison because in the dosage in which it's frequently encountered, introduction into the blood stream will often cause dramatic results that are harmful to the subject. Note that in its traditional use (before it made its ways into anesthesiology), it was used to bring down very small animals for food, so the comparative effective dosage was quite tiny.
It functions as an Acetylcholine antagonists. Acetylcholine was the first neurotransmitter to be discovered. A nicotinic antagonist inhibits Acetylcholine's receptors.
They can come by loud sounds and blood.
It depends an the animal: Cows, deer and elk come in herds Whales come in pods Fish come in schools or shoals Crows come in murders Baboons come in troops Many birds come in flocks Bees come in swarms Quail come in coveys
No animal eats the plant curare. This is because the plant curare is toxic. The plant is poisonous and therefore is not consumed by animals.
CURARE PARAlYSES MUSCELS
Plants are useful for many things. Some plants give us medicine. Other plants supply us with poison So that we can get rid of our teachers. Curare for example was developed By South American indigenous people From the foliage of the Calebas. Macusi Indians graded their Curare As One Tree Curare, Two Tree Curare ... and so on. To show how many trees a monkey could jump Before the Curare caused him to stop breathing. We would call our Curare One Lesson Curare, Two Lesson Curare .... and so on. Do teachers breathe?
Doctors use curare to help keep animals alive during surgeries. The curare helps to keep the animals respiratory systems going during surgery.

Curare is a competitive inhibitor of acetylcholine. It fights with acetycholine for postsynaptic receptors.
Curare poisoning is caused by the ingestion or injection of curare, a plant-derived toxin commonly used as a muscle relaxant. Symptoms of curare poisoning include paralysis, respiratory failure, and potentially death if left untreated. Treatment involves supporting vital functions and administering antidotes like cholinesterase inhibitors.

Curare is not hazardous if taken by mouth; it must be administered into the bloodstream. When it is in the blood, it can cause paralysis of all nerves and muscles.
Curare was originally used by indigenous peoples in South America. The substance was first described by Spanish conquistadors in the 16th century. The modern understanding of curare and its use in medicine was further developed by scientific researchers in the 19th and 20th centuries.
Curare does NOT create an action potential. It binds to nicotinic acetylcholine receptors (which are primarily excitatory), and prevents the formation of an action potential.
