The toxin that fits this description is ricin, which is derived from the castor bean plant. Ricin can be used as both a biological and chemical weapon, and is extremely potent, with just a tiny amount being able to cause death. Strychnine is also a highly toxic compound, but is not typically used as a weapon. Anthrax is a biological weapon, but is not a toxin itself. Mad cow disease is a prion disease and not a toxin or weapon.
