Botulinum, I'd guess (among natural toxins). A casual Google seems to indicate I'm right.

  Yup. 10x more toxic than palytoxin. And we inject it in ourselves voluntarily. Humans are such funny creatures.

    There is a poisonous dosage of ALL chemicals. H2O among them. The question is, is there a dosage of botulism that has a therapeutic effect?

      Botulinum toxin type A is known as "Botox." It has some therapeutic uses, but mostly cosmetic ones. http://en.wikipedia.org/wiki/Botulinum_toxin http://en.wikipedia.org/wiki/Botulinum_toxin
