Botox injections are the best known of a group of medications that use various forms of botulinum toxin to temporarily paralyze muscle activity. This toxin is produced by the microbe that causes botulism, a type of food poisoning.

Botulinum toxin helps to  reduce the appearance of some facial wrinkles,  to treat  repetitive neck spasms (cervical dystonia) and  excessive sweating (hyperhidrosis) beside its role in other medical problems such as preventing chronic migraines in some people.

While Botox was the first drug to utilize botulinum toxin, other  products include Dysport, Myobloc and Xeomin.
