Is complimentary and alternative medicine an alternative approach to conventional allopathic medicine?

No: If you get seriously sick, the treatment you get is evidence based. You're not getting it because it's "conventional" or because of a cultural or power-grab conspiracy, it's because it's what's most likely to work, as can be shown in the courts of science and the law. "Alternative" stuff like laetrile and gallstone flushes preys on the gullibility of desperate people.
