Access to medical databases is a keystone for obtaining up-to-date and comp
lete information for physicians. In the last few years, the rapid growth of
the World Wide Web has given rise to an information revolution, enabling h
ealth care providers to gain access (often free) to an expanding volume of
information that was previously inaccessible. Search engines and online dat
abases assist the search for health information. In this article we examine
the biomedical databases of primary interest in the field of alternative a
nd complementary medicine, dividing them into Web accessible and nonaccessi
ble databases and emphasizing the freely available ones. A further classifi
cation is major biomedical bibliographic databases specific to complementar
y medicine, and dedicated therapy or modality-specific databases.
