Enhancer

Botox's appeal as a skin enhancer was discovered by chance. Doctors knew that botulinum bacteria kill by paralyzing the diaphragm and preventing victims from breathing. The toxin the bacteria produce, botulin, blocks brain messages to muscles.

Mucuna pruriens' Latin name may be thought to suggest its predilection, but actually means itchy. Nonetheless, one can easily find it being sold in capsules as a sex enhancer. It has actually been used as such in Ayurvedic medicine for centuries.
