Complementary and alternative medicine (CAM) has received increased attention in mainstream medicine since a 1993 study demonstrated that one-third of US adults used some form of “unconventional medicine.”1 By 2002, the prevalence of CAM use by adults had increased to 62% to 68%,2,3 and it has become clear that users of CAM are not primarily dissatisfied with conventional care, but have a more holistic approach to health4 or simply appreciate multiple treatment options.5 What was once identified as “alternative medicine” has become “complementary,” “holistic,” and “integrative”; indeed, CAM therapies, such as probiotics, melatonin, massage, yoga, and acupuncture, have become part of the conventional medicine armamentarium, and the demarcation between CAM and mainstream medicine continues to shift.
