BRIEF: Do you have any information on a plant called

I am looking for information about a plant used by the shamans in the Amazonian. They use a plant that they call "camalonga" during the ceremonies and healing sessions they carry out. The only informatioon I have about the plant is that it belongs to the Sthrycnos sp., no more. I would like to know the actives principles of the plant.


The Strycnos genus is a big one, with more than a dozen toxin-producing species documented with structurally characterized toxins in the literature. I guess curare and strychnine would be the two most famous poisons found in members of this genus. There are similar indole and bisindole toxicants distributed throughout this genus as well.
