As one of its mandates from Congress, NCCAM is charged with "the dissemination of health information… with respect to identifying, investigating, and validating complementary and alternative treatment, diagnostic, and prevention modalities, disciplines, and systems." (Public Law 105-277) The NCCAM Clearinghouse serves this mission. It is the public's point of contact for scientifically based information on complementary and alternative medicine and for information about NCCAM.

The NCCAM Clearinghouse does not provide medical advice or referrals to practitioners. Decisions about medical care and treatment should be made in consultation with a health care provider, based on the condition and needs of each person. NCCAM recommends discussing information on complementary health approaches with a health care provider before making any decisions about treatment or care.
