Of course it would be pulled from the market and huge lawsuits would ensue over the horrific side effects.
It may be patented as a "new medicine" but I doubt the FDA would approve it, simply because it is so easy to make and because the side-effects are only temporary.
The drug companies make millions on drugs that have lasting side-effects because they can manufacture other drugs to counter-act the side effects of the drug they manufactured last year.
The idea is not to HEAL a patient, but to make them dependent on certain drugs that most people can't afford.
