1. What is CAM on Pubmed?
CAM on PubMed contains citations to
journal articles related to complementary and alternative medicine (CAM).

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.
