As one of its mandates from Congress, NCCIH is charged with “the dissemination of health information” (42 USC § 287c–21). The NCCIH Clearinghouse serves this mission. It is the public's point of contact for scientifically based information on complementary and integrative health interventions and for information about NCCIH.

The NCCIH 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. NCCIH recommends discussing information on complementary health approaches with a health care provider before making any decisions about treatment or care.
