Government-sponsored research into natural therapiesral therapies

There are a ton of diseases that could be cured or alleviated with minimal side effects using natural therapies. However, no corporation would invest the time and money researching and marketing a natural cure because there would be no patent rights and they'd lose their investment. So instead we get manufactured chemicals with side effects almost as bad as the disease they're meant to treat. What we need is a medical research arm of the government searching for cures using natural products. The results should be posted and use encouraged by prescribers, perhaps increasing reimbursement rates.
