There's a saying over here: There's no alternative medicine. There's just medicine (supported by evidence and science) and quackery.

The problem is that what is usually labelled as "alternative medicine" takes parts of the first and mixes it with the second to varying degrees. Some approaches are pure quackery, others are largely medicine with some vestigial quackery.

The task then becomes to take those parts which actually work and discard the rest (because it's either useless or downright dangerous).

I, for example, am currently suffering from a spot of mild hypertension. The first things we went through? What's my diet like? How active am I? Sports? We then decided on some changes to sport and diet. No medicine unless it becomes worse or the changes don't show an effect.
