Environmentalism as a value pulled me toward the job that drew me into integrative medicine 35 years ago. Part of the magnetism was learning that a primary charge in the field with which I was deciding whether to become involved was to aid and abet the healing power of nature. I surmised that such teaching would make patients of such doctors acolytes of the environment if they weren’t already. For this and other reasons, the environmental movement’s still limited embrace of the broader integrative domain as a core ally has continuously surprised me. If it is science one needs to bind these together, a recent Grand Rounds at Harvard Medical School included intriguing arguments. Peter Wayne, PhD, the interim director of that institution’s Osher Center for Integrative Medicine locked the two movements together through an array of existing, emerging and suggestive evidence.
