Admittedly, my original post was a little confused...my apologies. ;(
However, I would still be interested to learn of case studies and research - scientific or otherwise - that examines the use of traditional medicine to treat leaky gut/candida etc.
The article I linked to contains a considerable amount of information, and is clearly written by a practitioner with considerable knowledgeable of his field. As noted previously, I believe a holistic approach that draws upon several different approaches and forms of treatment is the the best way to heal the body (or should that be allow the body to heal itself?).
