Though it’s best known for smoothing wrinkles, Botox, which is derived from one of the most deadly toxins known to man, has repeatedly stunned the medical community for its seemingly endless applications. Though the drug is approved for nine medical conditions and several cosmetic ones, Allergan, the company that owns Botox, holds close to 800 more patents for potential uses of the drug. Since it was approved nearly 30 years ago, Botox has indeed become a staple of cosmetic enhancement, but today, more than half of its revenue comes from its therapeutic uses for conditions as varied as chronic migraines and back pain to excessive sweating and twitching eyelids.
