I agree 100% with cloverleaffarm. I would also add that often pharmaceuticals are used to treat symptoms or mask symptoms which typically point to a larger problem. If you only chase symptoms you can't get to the heart of the problem or the cause and therefore you end up chronically on medication.
My problem with Western Medicine is that everything is treated as a "disease" itself rather than a symptom. Natural medicine does a better job of taking into account factors such as lifestyle, diet, etc. When you go to a doctor they ask your symptoms and write out a prescription for a pill. When you go to a Naturopathic practitioner, they ask you about your background, lifestyle, dietary habits etc and also make recommendations on those things in addition to remedies.
imo Western medicine could stand to learn a lot from "alternative" medicine. I'll take the alternatives thanks! I learned this lesson the hard way when an FDA approved drug prescribed by my doctor nearly killed me (and should never have been prescribed) I now have permanent damage done to my lungs and permanent long term memory loss. I was fit, active, and only 32 years old at the time - pitiful.
