How to evaluate claims

While nonconventional approaches such as acupuncture, music therapy and animal-assisted therapy have been found to be effective, others haven't been studied well enough to determine whether they're safe and effective.

When considering any treatment, take time to learn about the risks and benefits. Gather information from a variety of sources and check credentials. Talk with your doctor before trying a new treatment — especially if you take medications, have chronic health problems, or you are pregnant or nursing.
