If I were to try anything it would be Monkshood, or as most people know it as Wolf's Bane. I'm pretty sure it's used for landscaping in the US(not native), so you would have to grow it yourself. As for Africa I would look into poisonous sap from certain trees if you're in the right area. There's also a beetle that is poisonous in that area but I don't remember it's name. Though the beetle's poison could take days to kill the animal. Wolf's Bane on the other hand can take a couple of hours in small doses and be immediate in large. Never really know how much a small or large dose really is though.

The thing about using the poison is to go for larger game, so you have more meat. Normally once they had taken prey with their poison blow darts they would not eat the meat where the wound was. At least that's what I've heard. A lot of the poisons were not made to kill the animal, but to stun/paralyze, which are the poisons I'd like to make if ever needed. Such as Curare, it's a paralyzing poison. Though in sufficient doses it leads to death. As for working with the poisons, yes there are a lot of them that could in fact poison you just by working with it. Such as the sap of the tree I mentioned earlier. Nicotine is another toxin that has been used as a poison, 1 drop of pure Nicotine is enough to kill someone. It can be absorbed through your skin too, which is why you must wear protective clothing and eye wear when extracting it. Plenty of dangers when dabbling in poisons and such.

With some kinds of poison you could poisen your food & then yourself. Or yourself just working with the stuff.

I'm sure you could get hold of water hemlock. That is extremely potent too. Might work well with monkshood!

I'm sure I could easily find Water Hemlock, also able to find Poison Hemlock. Which is similar to Curare's workings where it causes paralysis of respiratory muscles which results in death due to lack of oxygen to the brain and heart. Also, it's similar to Nicotine. I've seen a lot of Poison Hemlock at the river I go night fishing/snagging at.

Nicotine seems easy to extract. If you want to look up The Anarchist Cookbook. Maybe also The Poor Mans James Bond. Nicotine has been used to kill insects on crops for some time. They may have stopped using it, but I do not know. Believe it or not most of what I typed has come from mystery novels and then I checked it online.

Seems to be expected since Nicotine is in fact a natural insecticide. That's the tobacco plants natural defense!
