Cons about Alternative Medicine??

Answer 1

Very few (or no) studies indicating effectiveness or even safety of many alternative treatments (especially herbal supplements).

Again, with herbals, the interactions they may have with eachother or other drugs are not well studied.

Often, the doses of drugs in alternative treatments are not accurately measured, so even if they do work, it's impossible to know how much you're getting.

Answer 2

I agree with "The Doc". At least with conventional therapy, they have a history of experiences (side effects, interactions, dosage, etc.), statistics (mean time to progression, mean survival time), a rationale behind its action (apoptosis by poison or radiation, binding of receptors, attack by immune system, etc.)

The shear number of alternative "cures" and the simple absurdity of most of the treatments should tell people that they are non-effective.

In defense of alternative treatment users, desparate people do desparate things.
