What is CAM on PubMed®?

CAM on PubMed® contains citations to journal articles related to complementary and alternative medicine (CAM). It was developed jointly by the National Library of Medicine (NLM) and the National Center for Complementary and Alternative Medicine (NCCAM) to help people search easily for journal articles related to a variety of CAM therapies, approaches, and systems—from acupuncture, to herbs, to traditional Oriental medicine.

CAM on PubMed® is a subset (a part) of all citations found on the NLM's PubMed and offers all of the features and benefits of PubMed.

What is PubMed?

PubMed is a database of the National Library of Medicine (NLM) that provides an easy way to access over 11 million journal citations in the MEDLINE database and additional life science journals. NLM is the world's largest library of the health sciences, located at the National Institutes of Health. PubMed is free and searchable through the Internet. In addition, PubMed has a “LinkOut” feature that links a citation to outside sources for the full text of the article (some publishers may require a subscription or a fee); over 2,700 journals are linked. Another feature of PubMed, “Related Articles,” lets you obtain a set of citations that are closely related to the selected article. NLM regularly adds new citations to PubMed.

What is complementary and alternative medicine (CAM)?

NCCAM defines complementary and alternative medicine (CAM) as those health care practices not currently considered an integral part of conventional medicine. It covers a broad range of healing therapies, approaches, and systems. Some examples of CAM include acupuncture, herbs, homeopathy, chiropractic, hypnosis, and traditional Oriental medicine.

A therapy is called complementary when it is used in addition to conventional treatments. It is often called alternative when it is used instead of conventional treatment. Most often, people who use CAM therapies are seeking ways to improve their health and well-being and to relieve symptoms and side effects of conventional treatment.

Who will use this database?

CAM on PubMed® will be used by researchers, CAM practitioners, health care providers, students, people with illnesses, their family and friends, advocacy organizations, and many others as a resource to find citations related to complementary and alternative medicine. Please note that it is not the intention of the NLM or NCCAM to provide specific medical advice, but rather to provide people with access to sources of information.

How many citations are included within CAM on PubMed®?

Currently, there are over 462,000 citations in the CAM subset of PubMed (from 1966 forward). As research in complementary and alternative medicine grows and more articles are published, we expect the number of citations to increase.
