Mainstream medicine has not been interested in finding a cure for anything for half a century now. There is no profit in cures - only in side-effect laden drugs that manage symptoms and lead to complications that require still more side effect laden drugs. Trillions of dollars in profits are at stake and the only marketplace is our bodies! All the "Ask Your Doctor" commercials in the world, complete with smiling healthy actors cannot cover up those simple facts.
Allowing safer and more effective natural and alternative competition is not profitable either - and you know what happens when you try!
