The pervasiveness of different modalities of TM and CAM varies greatly from country to country. For example, in China, where traditional Chinese medicine is well integrated into the health system,many different modalities may be used to treat a given condition. In the United States, by contrast, CAM pro- grams are slowly being integrated with conventional medicine. Several medical schools have nascent CAM programs and have integrated them into medical school curricula to differing degrees. One of the more acclaimed programs of this kind in the United States is that developed by Andrew Weil at the University of Arizona Health Sciences Center. His Integrative Medicine Fellowship Program trains physicians in CAM and TM.
