The Botto did not have as much penetrating power as other similar sized bows, as evidenced by its inability to pierce the Jaguar's cotton armor. However, the arrows were tipped with Benge, a red powder made from a type of forest creeper vine known by the Zande as a liana. The Benge contains strychnine, which is commonly used as a pesticide.
Poison-tipped darts and arrows have been used by tribes and civilizations around the world. Some noticeable natural sources of poisons used by such weapons include: the manchineel ("beach apple") tree in Florida, the poison dart frog in the Amazon, and the wolfsbane plant (also known as achonite, or monks' hood) in China.
