Gee I really don't consider Linus Pauling to be a semi-quack, and considering he's the guy who coined the phrase.... http://orthomolecular.org/hof/2004/lpauling.html

I know the pharma industry has been trying to destroy his reputation regarding his vitamin C (l-ascorbic acid) L-lysine protocol as a way to prevent and revers heart disease. But so far it seem that everything Dr. Pauling proposed has been panning out. Frankly I'd blindly trust Dr. Pauling over basically anyone else, especial if the anyone else has a financial stake in their position, which is everyone, except Dr. Pauling.

It's too bad he was prevented from traveling due to his protesting the Vietnam War, because if he hadn't be prevented from traveling he would have stayed ahead of Watson and Crick and Dr. Pauling would have "discovered" the double-helix, and won his 3rd solo Nobel Prize.
