I'm a firm believer that the focus of western medicine is to treat a condition rather than cure it. The "treatment" option implies a prolonged drug regemin and multiple return visits by the patient.
With that in mind, I have read about a few drugs that have shown remarkable potential in conditions for which they were not developed however no pharmaceutical company would sponsor clinical trials due to patent expiration. One such drug named Naltrexone was developed to assist heroin addicts and alcoholics in overcoming their addiction. It wasn't until later when a researcher discovered that Naltrexone inhibited cell proliferation (cancerous growth). Since then, Naltrexone has been shown (anecdotally) to benefit suffers of conditions ranging from MS to Arthritis.
