Medicinal
Curare, obtained from the bark of the stems, is a very toxic substance used in the Amazon as an arrow poison. It does also have medicinal applications; as a sedative, anticonvulsive etc. However, the toxic dose is very near the pharmacological dose and so it has to be used with great care.
Curare is a powerful paralyzing agent of the motor nerves. Its active principle is Curarin[
