Botulinum Toxin is the world's deadliest poison and the most poisonous naturally occurring substances. It is a neurotoxin protein produced by the bacterium Clostridium botulinum.

Though it is highly toxic, it is used in minute doses both to treat painful muscle spasms, and as a cosmetic treatment in some parts of the world. It is sold commercially under the brand names Botox, Dysport, and Myobloc for this purpose. The terms Botox, Dysport, and Myobloc are trade names and are not used generically to describe the neurotoxins produced by C. botulinum.
