Arrow poison

Arrow poisons are used to poison arrow heads or darts for the purposes of hunting and warfare.

Strychnos toxifera, a plant commonly used in the preparation of curare
The black-legged dart frog, a species of poison dart frog whose secretions are used in the preparation of poison darts.

In Africa, many arrow poisons are made from plants that contain cardiac glycosides, such as Acokanthera (possessing ouabain), oleander (Nerium oleander), milkweeds (Asclepias), or Strophanthus, all of which are in the family Apocynaceae. Inee or onaye is a poison made from Strophanthus hispidus, which contains the cardiac glycoside strophanthin. It is used in sub-Saharan West Africa, particularly in the areas of Togo and Cameroon. Certain species of the genus Mostuea (family Gelsemiaceae) are used as additives to arrow poisons (other ingredients unspecified). The toxic principles of Mostuea are alkaloids, not cardiac glycosides.
