Here is an excerpt from http://www.wholebodywellnesssolutions.com/fungus101.html

There are millions of Americans who I believe would benefit tremendously by taking antifungal remedies, but one major problem exists-physicians rarely prescribe them because they feel that infectious agents are almost exclusively bacterial or viral. Through the years, when symptoms of unknown etiology (cause) exist, I have asked hundreds of physicians to prescribe a nontoxic, no-side-effect drug called Nystatin in hopes of reversing the symptom or disease in the patients. Rarely has this occurred, however, for two reasons: So often, the prescribing physician does not believe in the fungus-disease phenomenon, and also he is concerned that Nystatin may harm the liver of the patient. The fungus-disease link is very well documented in the scientific literature, the same literature that also documents the harmlessness of Nystatin.What is an educated patient to do when an antifungal approach seems so logical to them, yet their physician will not prescribe antifungal drugs? First and most importantly, understand why the physician will not prescribe antifungal drugs, because there may be a very good reason. Ask the doctor if he would object to your trying the antifungal diet and natural, nontoxic antifungal remedies. Most docs will not object, believing that these antifungal remedies are not as strong as antifungal drugs; yet, as you will read, some are more capable of killing fungus than even the most powerful antifungal drugs.
