Botulinum toxin, the deadliest toxin, causes botulism and can lead to paralysis and respiratory failure. It is 10 million times more lethal than cyanide and can enter the body through wounds or contaminated food. Botox, a purified version, is used for cosmetic purposes.
The deadliest toxin is botulinum toxin, a type of bacterium that causes botulism, a condition that can result in paralysis of the central nervous system and lead to respiratory failure. It is thought to be more than 10 million times more lethal than cyanide. Botulinum toxin can enter the body through open wounds or by consuming contaminated food. Purified versions of botulinum toxin, including the well-known brand name Botox®, are approved for cosmetic use and are often injected into people’s faces to smooth out wrinkles. It works because traces of the toxin cause a slight and temporary paralysis of the facial muscles that cause wrinkles.
