Botox comes from the bacteria Clostridium botulinum, a naturally occurring bacteria found in soils, forests, and lakes. It is also found in the gills and organs of crabs and various other shellfish, as well as in the intestines of fish and various mammals.
Bacteria and spores are practically harmless, and problems don't arise until the spores become vegetative cells and then grow. At some point, the bacteria started producing botulinum toxin, and it was fatal.

In fact, scientists have calculated that just one gram of botulinum toxin can kill one million people, while a few kilograms can destroy the entire population of the planet.
However, botulinum toxin has proven useful when injected into humans at very low concentrations. This prevents the cells in the muscles from contracting, allowing them to relax and become less stiff.
For a muscle to contract, it must receive signals from nerve cells. At the point where nerve cells meet muscle cells, they release a chemical messenger called acetylcholine. Acetylcholine binds to receptors on muscle cells and causes muscles to contract.
Botulinum toxin prevents the release of acetylcholine by nerve cells, which means muscles don't contract. Botulinum toxin is currently used to treat several different conditions, in addition to treating wrinkles and fine lines on the face.
