Antibiotics, anti-fungal medications, and anti-parasitic medications are simple, safe, effective, and true cures for those purposes. The FDA restricts these and makes the population go through their system to access them. This gives the medical community leverage and the appearance of legitimacy as they oversee these cures. So when you come to them with another problem they can prescribe you a patented chemical that will treat the symptoms of what you have. They will never solve the underlying issues (usually a lack of fitness, poor diet, exposure to something that is harming you, or lack of vitamins or some other necessary component of your construction).
