Down below someone mentions the benefits of holistic medecine, but quickly qualifies their reference to it as not being about New Age.
I think that many people take the New Age label to be something negative or evil.
Under the label Christianity a lot of people would list Mother Theresa along with massacres of the Crusades.
What I'm trying to say is that it was New Age writers like Louise L. Hay who've helped bring Holistic health care into the mainstream.
