quackwatch is just a front org for a bitter man who lost his medical liscense and now spend his time spreading lies about wholistic health measures. he is very good at looking and seeming legit, but he and his entire group of web pages (quack watch, quack this and quack that) are just ways to discredit natural healing methods, please don't take anything you read there as credible. do some REAL research before deciding anything about MSM.
