What would alternative medicine do?

I like reading blog's on Skeptical Thinking and one of the best is Skeptico. He's got a very good article here about the key difference between Real Medicine and "Complementary/Alternative Medicine (CAM)".

To summarise:
Testing on an experimental AIDS vaccine has been halted as the test results showed it wasn't working. Now, when was the last time a CAM practitioner/advocate stopped providing "therapy" because they know it doesn't work for condition X?

Skeptico provides some suggestions but I'll repost one here, read the article for the rest.

Acupuncturists pulling acupuncture for treatment of (say) arthritis, because they determined it doesn’t work for that.
