Is there any scientific basis for CAM?

While the amount of scientific data derived from CAM trials is scant at this time, many studies are underway through grants from the National Center for Complementary and Alternative Medicine (NCCAM). It is worth noting that many prescription and over-the-counter medications are derived from botanical substances, so there may be a rational basis for some CAM preparations. For instance, aspirin, or salicylic acid, is derived from a plant, white willow bark.

Many studies have established that prayer, meditation, and spiritual support affect the functioning of the immune system in a positive manner.

Within the orthopaedic realm, some clinical trials are showing promising results for musculoskeletal and surgical concerns. Glucosamine sulfate may be effective for reducing further osteoarthritis of the knee, acupuncture may help prevent post-operative nausea, mind/body techniques may reduce pain, and osteopathic manipulation may help reduce lower back pain.
