I would want something much faster acting than aconitine if I was going to put a spear into a giant cave bear even if it meant the meat would be poison. I want his cave and I don’t want him chasing me around after the spear incident.
Is there a fast poison incident to the midwest US? I don’t remember the native north americans using poisonous arrows like the central and south americans did.
Nicotine was used by some North American tribes as arrow poison. Don’t know of anything faster than aconitine outside of the tropics.
