I think there's been some misunderstanding somewhere.

While I can make and apply poison (stews are a pretty long-winded way of doing it if you already have poison), I'm not very good at poisoning people without them realising I did it, which is half the appeal of poison in the first place.

You can't really present them with it, as they'll know you killed them once they eat it (depending on your strategy, they may even know before they eat it, "Here's a peace gift" is probably the least subtle way of saying "I have poison" possible). Going into their tribe and poisoning/planting food is very difficult to manage without them noticing your presence, and I haven't met a single tribe who doesn't keep a close eye on strangers who beeline for their food supplies.
