The strongest poison is botulinum toxin which is also the world's most dangerous poison.
Botulinum toxin is a purified substance that's derived from bacteria.
Injections of botulinum toxin block the nerve signals to the muscle in which it was injected. Without a signal, the muscle is not able to contract. The end result is diminished unwanted facial wrinkles or appearance.
Botulinum toxin, one of the most poisonous biological substances known, is a neurotoxin produced by the bacterium Clostridium.
The Botulinum toxin is commonly used in Botox injections and is safe when used as directed.
But when used wrongly it can be deadly.
The most commonly treated areas with Botox or Botulinum toxin are frown lines, forehead creases and crow's feet near the eyes. Several other areas have been treated such as thick bands in the neck, thick jaw muscles, lip lines and gummy smiles. Botulinum toxin is a purified substance that's derived from bacteria.
The median lethal dose of the botulinum toxin for humans has been estimated at 2 nanograms of botulinum toxin per kilogram of bodyweight, which is approximately 3 times greater than in foodborne cases.
Following inhalation of the toxin, symptoms become visible between 1–3 days, with longer onset times for lower levels of intoxication.
As a military or terrorist weapon, botulinum toxin could be disseminated via aerosol or by contamination of water or food supplies, causing widespread casualties.
