The US National Institutes of Health provides access to vast medical and scientific databases, all under the banner PubMed. With PubMed you can plug in the name of an herb and instantly receive a list of scientific studies on that plant. PubMed is an extraordinary resource, of value to anyone who wants to really understand this field.


PubMed comprises over 20 million citations for biomedical literature from MEDLINE, life science journals, and online books. PubMed citations and abstracts include the fields of medicine, nursing, dentistry, veterinary medicine, the health care system, and preclinical sciences. PubMed also provides access to additional relevant Web sites and links to the other NCBI molecular biology resources.

PubMed is a free resource that is developed and maintained by the National Center for Biotechnology Information (NCBI), at the U.S. National Library of Medicine (NLM), located at the National Institutes of Health (NIH).

Publishers of journals can submit their citations to NCBI and then provide access to the full-text of articles at journal Web sites using LinkOut.
