Everything you always wanted to know...

...and could never remember after you asked!

It's the Medilexicon, and it is free reference for medical terms, abbreviations, treatments, companies, brand/generic names and medical news. There are also descriptions of various illnesses, conditions, and injuries, too.

This is a commercial site (was Pharmalexicon) and will have some advertising and a definite slant towards allopathic and pharmaceutical medicine, but the information is still useful because unlike the Merck Manual, it is in English for non-medical folks.
