I've seen enough on Dr. Oz to consider him a quack (at least for a fair bit on his show--yes, he is probably a fine surgeon). But he's a believer in Reiki, which is quackery at its finest.
I had heard of Dr Oz before but never saw his show until a few days ago while waiting for a family member I took to the doctors office...his show reminded me of a late night infomercial...he had a supposed health guru pushing a weight loss book showing some BS special formula diet and exercise program. Just all around facepalm!
