Any use of a 3rd-party image/logo or participation in or use of a 3rd-party Web site does not imply endorsement.

What is the source of the medical information on this site?

Medical information presented on this site is derived from rigorous research on complementary and alternative medicine. Fact sheets produced by NCCAM are carefully reviewed by both NCCAM scientists and outside experts. The NIH has developed information quality guidelines to maintain the high quality of information.


Does NCCAM provide medical advice or referrals?

It is not the intention of NCCAM to provide specific medical advice, but rather to provide users with information to better understand complementary and alternative medicine. Mention of a specific treatment or resource on NCCAM's Web site does not imply endorsement by NCCAM, NIH, or DHHS.

NCCAM cautions users not to seek the complementary and alternative therapies described on this site without consulting a licensed health care provider to discuss both the advantages and risks of complementary and alternative medical treatments.

If you contact the NCCAM Clearinghouse for information, please be aware that specific medical advice or referrals to alternative health care practitioners cannot be provided. Information Specialists at the NCCAM Clearinghouse are trained to assist callers and provide other sources of information. However, because Information Specialists are not health care professionals, the information they provide cannot substitute for the medical expertise and advice of your primary health care provider.

  • We collect no personally identifiable information (PII) about you unless you choose to provide that information to us.
  • Any PII you choose to provide is protected.
