What is integrative medicine?

[M.C.]

I have found in my studies that integrative medicine can be defined many differant ways.

I found a defintion that is kind of broad, but I think it works.

INTEGRATIVE MEDICINE: Alternative and conventional (allopathic) methodologies are combined to stimulate the person's natural healing response.

So reiki, massage, meditation,yoga are some teachings that could fall under integrative medicine.
