Acokanthera schimperi (DC) Oln.
(Carrissa schimperi) DC
oboyo, wabayo (Som)
mephteh, mephthi, merenz (T)
This is a monoecinus shrub or small tree up to a height of 5-6 meters and a diameter of 30 cm, widely used in the preparation of arrow poisons.
Extraction of poison:
Because of the extreme toxicity an underground fire pit is built and the pot is kept below ground level. People are made to stay away from the area of extraction and the operator needs to be careful.
The fire is kept going for 3 to 4 days after which time the lid is removed to let the vapor escape. Allowing it to stay open for one day results in a precipitate deposited at the bottom of the pot. The precipitate is then removed to a wooden or leather container with a tight lid. It is then carried around for use in the preparation of poison arrows. The bark is also soaked in water to extract the poison.
Death results in 30 minutes after entry of poison into the blood-stream" Snake venom is sometimes used in addition. The poison causes hair and nails to drop off
The only treatment against the poison is immediate excision of the flesh surrounding the wound.
The container used to prepare or hold the poison must never be used in the house again, not even to burn as firewood because the smoke if inhaled, is poisonous as well. Whole plant is smoked to ward off or kill insects the smoke for the wood is inhaled to treat liver diseases.
