Botulinum toxin and Botox are classic examples of the basic dose-response principle of toxicology, and I usually cite them when explaining toxicology in general. Sure, it's the most potent toxin known to humanity, but at a proper dose it's fairly harmless (though, perhaps not aesthetically harmless). It should be noted that Botox is used for more than hideous plastic surgery. As noted earlier, Botox is a nerve poison which paralyzes muscles by preventing the release of acetylcholine from the synapses of cholinergic neurons. This has been shown to be usefully therapeutic in cases of nerve dysfunction in the head and neck area. PubMed has a fairly good review here.
