) I am subscribed to quite a few health sites such as Natural News, Dr Mark Hyman, Chris Kresser, Mercola, Medscape
. There is also google scholar. If you are not sure where that is, the top part of google with news, images etc..there is the word "more" at the end. Click on that for extra stuff..like scholar..oh and the translator! love that!
As for a free medical site, pubmed is excellent. You can type anything you want into the search bar.
