Complementary and alternative medicine (CAM) includes a range of therapies and health care systems, practices, and products that are outside of standard medical practice in the United States (U.S.). CAM treatments generally have fewer side effects and address the range of symptoms that patients with complex disorders, such as posttraumatic stress disorder (PTSD), experience. The U.S. Department of Veterans Affairs (VA) is committed to providing cutting-edge, evidence-based treatment for all Veterans, including those seeking PTSD-related services. Acupuncture is one of the most mainstream of the CAM treatments. It is based on traditional Chinese medicine (TCM) and involves inserting very thin needles along meridian points to stimulate the flow of energy. Mindfulness is another CAM modality that has been integrated into trauma treatment. Another CAM treatment for trauma is expressive writing. One mechanism by which expressive writing was thought to be effective was in helping trauma survivors.
