I do not believe anything without a proven, positive effect on illness should be called medicine, regardless of what word you place in front of it. Alternative medicine is, for the most part, a scam through and through, with homeopathy leading the charge of course, selling water for hundreds of dollars per bottle. I especially dislike it because the Greens here in Sweden have managed to convince Parliament to give an "alternative healthcare clinic" huge funds from taxpayer money, and said they await clinical studies proving its efficacy. Not studies on its efficacy, studies proving its efficacy.
My main concern with it is that it is much the same as "prayer healing": People with real, serious illnesses go to these people instead of doctors, and so die from disease we can cure or at least treat. The reason "Western medicine" dominates the healthcare landscape isn't because of imperialism or anything, it's because it works.
