Medline Plus Consumer Health Information

MedlinePlus is an online portal for consumer health information that, unlike the for-profit WebMD health website, features no advertising or product endorsements. Its centerpiece is the A.D.A.M. Medical Encyclopedia, an illustrated and continually updated reference source with 4,000-plus articles about diseases, tests, symptoms, injuries, and surgeries. Site visitors, from patients to caregivers to those who are proactive about living a healthy lifestyle, will find information on medical tests, genetics, and drugs and supplements, as well as healthy recipes and useful videos. Hundreds of topic pages curate links to other reliable resources. Users can toggle seamlessly between English and Spanish.


Medline Plus is presented by the U.S. National Library of Medicine, a unit of the National Institutes of Health [NIH]. The National Library of Medicine [NLM] has been a center of information innovation since its founding in 1836. The world’s largest biomedical library, NLM maintains and makes available a vast print collection and produces electronic information resources on a wide range of topics that are searched billions of times each year by millions of people around the globe. It also supports and conducts research, development, and training in biomedical informatics and health information technology. In addition, the Library coordinates a 6,500-member Network of the National Library of Medicine that promotes and provides access to health information in communities across the United States.
