PubMed

PubMed is where you can search for published research on any drug, herb or supplement and comprises more than 25 million citations for biomedical literature from Medline, life science journals, and online books. Citations may include links to full-text content from PubMed Central and publisher web sites.

For Example; search ginger root and colorectal cancer or ginger root and nausea!

It is an amazing resource for anyone interested in learning the truth rather than seller’s hype!
