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 integrative medicine. Fact sheets produced by NCCIH are carefully reviewed by both NCCIH scientists and outside experts. The NIH has developed information quality guidelines to maintain the high quality of information.
Does NCCIH provide medical advice or referrals?
It is not the intention of NCCIH to provide specific medical advice, but rather to provide users with information to better understand complementary and integrative medicine. Mention of a specific treatment or resource on NCCIH's website does not imply endorsement by NCCIH, NIH, or DHHS.
NCCIH cautions users not to seek the complementary and integrative therapies described on this site without consulting a licensed health care provider to discuss both the advantages and risks of complementary and integrative medical treatments.
If you contact the NCCIH Clearinghouse for information, please be aware that specific medical advice or referrals to complementary health care practitioners cannot be provided. Information Specialists at the NCCIH 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.
