How Can I Get Reliable Information About A CAM Therapy?

It is important to learn what scientific studies have discovered about the therapy in which you are interested. It is not a good idea to use a CAM therapy simply because of something you have seen in an advertisement or on a Web site or because someone has told you that it worked for them.

Understanding a treatment's risks, potential benefits, and scientific evidence is critical to your health and safety. Scientific research on many CAM therapies is relatively new, so this kind of information may not be available for every therapy. However, many studies on CAM treatments are under way, including those that NCCAM supports, and our knowledge and understanding of CAM is increasing all the time. Here are some ways to find scientifically based information:

  • Talk to your health care practitioner(s). Tell them about the therapy you are considering and ask any questions you may have about safety, effectiveness, or interactions with medications (prescription or non-prescription). They may know about the therapy and be able to advise you on its safety and use. If your practitioner cannot answer your questions, he may be able to refer you to someone who can. Your practitioner may also be able to help you interpret the results of scientific articles you have found.
  • Use the Internet to search medical libraries and databases for information. One database called CAM on PubMed, developed by NCCAM and the National Library of Medicine, gives citations or abstracts (brief summaries) of the results of scientific studies on CAM. In some cases, it provides links to publishers' Web sites where you may be able to view or obtain the full articles. The articles cited in CAM on PubMed are peer-reviewed-that is, other scientists in the same field have reviewed the article, the data, and the conclusions, and judged them to be accurate and important to the field. Another database, International Bibliographic Information on Dietary Supplements, is useful for searching the scientific literature on dietary supplements.
  • If you do not have access to the Internet, contact the NCCAM Clearinghouse. The staff is available to discuss your needs with you and assist you in searching the peer-reviewed medical and scientific literature.
  • Visit your local library or a medical library to see if there are books or publications that contain scientific articles discussing CAM in general or the treatment in which you are interested. Thousands of articles on health issues and CAM are published in books and scientific journals every year. A reference librarian can help you search for those on the therapy that interests you.

Questions to ask when evaluating Web site information:

  • Who runs the site? Is it Government, a university, or a reputable medical or health-related association? Is it sponsored by a manufacturer of products, drugs, etc.? It should be easy to identify the sponsor.
  • What is the purpose of the site? Is it to educate the public or to sell a product? The purpose should be clearly stated.
  • What is the basis of the information? Is it based on scientific evidence with clear references? Advice and opinions should be clearly set apart from the science.
  • How current is the information? Is it reviewed and updated frequently?
