Needless to say, this isn't the first case of this. Big Pharma has a notorious history of sidelining natural therapies and cures in favor of making money with chemical treatments that often have negative long-term side effects (Prozac, Ritalin, Avandia, OxyContin). If they can't hold exclusive rights and make big profits, not only will they not seek government approval, they will often go so far as to have it declared illegal (marijuana).
