The National Center for Complementary and Integrative Health (NCCIH) is a United States government agency which explores complementary and alternative medicine (CAM). It was created in 1991 as the Office of Alternative Medicine (OAM), and renamed the National Center for Complementary and Alternative Medicine (NCCAM) before receiving its current name in 2014. NCCIH is one of the 27 institutes and centers that make up the National Institutes of Health (NIH) within the United States Department of Health and Human Services. NCCIH has been criticized for funding and marketing pseudoscientific medicine and quackery.
Organization and history
Overview The Office of Alternative Medicine (OAM) was established in October 1991 by the United States Congress. The OAM was expanded from an office into a center and renamed the National Center for Complementary and Alternative Medicine (NCCAM) in October 1998. It is one of several centers within the National Institutes of Health (NIH). The founding director of the center was Stephen Straus. In 2008, Josephine Briggs became the second director of NCCAM. The NCCAM was renamed the National Center for Complementary and Integrative Health (NCCIH) in December 2014. Helene Langevin was director from August 2018 to November 2025. The 2014 name change to NCCIH has been described by critics as an attempt by the center to mitigate criticism by avoiding the term "alternative" and distancing itself from having funded studies of questionable merit. The 2001 mission statement of the NCCAM stated that it was "dedicated to exploring complementary and alternative healing practices in the context of rigorous science; training complementary and alternative medicine researchers; and disseminating authoritative information to the public and professionals." As NCCIH, the mission statement is "to define, through rigorous scientific investigation, the usefulness and safety of complementary and alternative medicine interventions and their roles in improving health and health care".
As the OAM (1991–1998) Joseph J. Jacobs was appointed the first director of the OAM in 1992. Jacobs' support for rigorous scientific methodology caused friction with Democrat U.S. Senator Tom Harkin and other OAM patrons. Harkin believed his allergies had been cured by bee pollen pills and expressed frustration with the "unbendable rules" of randomized clinical trials, saying, "it is not necessary for the scientific community to understand the process before the American public can benefit from these therapies." Harkin's office reportedly pressured the OAM to fund studies of favored theories, including the use of bee pollen and antineoplastons as treatments. OAM board member Barrie Cassileth publicly criticized the office as a purveyor of nonsense and described it as a "place where opinions are counted as equal to data". After Harkin appeared on television in 1994 with cancer patients who blamed Jacobs for blocking their access to antineoplastons, Jacobs resigned from the OAM in frustration. In an interview with Science, Jacobs criticized Harkin and other politicians for pressuring his office, promoting certain therapies, and, he says, attempting an end-run around objective science." Harkin drew support from Iowa Democrat Representative Berkley Bedell, who believed that cow colostrum had cured his Lyme disease. The OAM's budget grew in the 1990s. The office drew increasing criticism for its perceived lack of rigorous scientific study of alternative approaches favoring uncritical boosterism. Paul Berg, a Nobel laureate in chemistry, wrote to the Senate that "Quackery will always prey on the gullible and uninformed, but we should not provide it with cover from the NIH," and called the office "an embarrassment to serious scientists". Allen Bromley, then-president of the American Physical Society, similarly wrote to Congress that the OAM had "emerged as an undiscriminating advocate of unconventional medicine. It has bestowed the considerable prestige of the NIH on a variety of highly dubious practices, some of which clearly violate basic laws of physics". Leon Jaroff, writing for The New York Times in 1997, described the OAM as "Tom Harkin's folly". In 1995, Wayne Jonas, a promoter of homeopathy and political ally of Harkin, became the director of the OAM, and continued in that role until 1999. In 1997, the NCCAM budget was increased from $12 million to $20 million annually. From 1990 to 1997, use of alternative medicine in the US increased by 25%, with a corresponding 50% increase in expenditures. The OAM drew increasing criticism from eminent members of the scientific community with letters to the Senate Appropriations Committee when discussion of renewal of funding OAM came up. In 1998, the President of the North Carolina Medical Association publicly called for shutting down the OAM. In 1998, NIH director and Nobel laureate Harold Varmus came into conflict with Harkin by pushing to have more NIH control of alternative medicine research. The NIH Director placed the OAM under stricter scientific NIH control. Harkin responded by elevating OAM into an independent NIH "center", just short of being its own "institute", and renamed it the National Center for Complementary and Alternative Medicine (NCCAM). NCCAM had a mandate to promote a more rigorous and scientific approach to the study of alternative medicine, research training and career development, outreach, and "integration". Stephen Strauss was the director of NCCAM from 1999 to 2006. He tried to bring more scientific rigor to the organization. In 1999 the NCCAM budget was increased from $20 million to $50 million. The United States Congress approved the appropriations without dissent. In 2000, the budget was increased to about $68 million, in 2001 to $90 million, in 2002 to $104 million, and in 2003, to $113 million.
