UA. I'm wanting to do the elective next year (we'll see what happens though). But honestly, there is so much out there with CAM, not to mention so many different philosophies and disciplines, that I do think it's something that you will need to really do some training with after residency (workshops, distance courses, and possibly the UA fellowship) in order to feel really comfortable. Part of why CAM is so easily demonized is because it includes everything from homeopathy (crap) to Ayurveda/Yoga (increasingly robust evidence) to acupuncture (needles and/or pressure on the skin are good, location doesn't seem to matter, no one knows why).
Part of what makes CAM hard is that even within a system that has some evidence-base and evidence of efficacy, you still have to separate the wheat from the chaff and THEN you have to get to know the substances pretty well in order to understand their risks and benefits. As an example, Ashwaganda has some fantastic properties, but you need to be careful of source due to heavy metal contamination and pregnant women really shouldn't go anywhere near it. And, at the end of the day you're still playing in a relatively uncharted world.
I have a real philosphical problem with the attitude of 'once we have the evidence it isn't CAM anymore', as it's basically a form of intellectual colonialism. But that's a rant for a different time and place.
But all the same, I think there's a real need out there for physicians who are friendly to Allopathic medicine as well as integrative medicine however.
