Botulinum toxin is a neurotoxin protein produced by the bacterium "Clostridium botulinum". Botulinum toxin produced by "Clostridium botulinum" is the cause of botulism. Botulinum toxin is effective in decreasing spasticity. Botulinum toxin injections have shown limited success. Botulinum toxin is the most poisonous substance known. Symptoms of botulism may occur away from the injection site of botulinum toxin. Medications such as diazepam, baclofen and botulinum toxin may help relax stiff muscles. Injections of botulinum toxin into the bladder is another option. Attempts to stockpile botulinum toxin proved unsuccessful. Evidence for baclofen, botulinum toxin, and capsaicin is unclear. Infants can develop botulism after consuming honey contaminated with "Clostridium botulinum" endospores. Subsequently, cosmetic use of botulinum toxin type A has become widespread. Anticholinergics, tranquillizing drugs and botulinum toxin are the mostly used therapeutic options. New uses for botulinum toxin have included treatment of hemiballismus. Mechanisms of entry into the human body for botulinum toxin are described below.
