I have no idea. I have been fighting this for 20 years, done the diet till the cows come home (which seriously being no enjoyment in life), the antifungals, been disagosed with other things that can be causing it, i.e. Mold, Lyme, etc. and am still no closer to relief. The only thing I haven't tried is Rifing and I will be trying that hopefully in a couple of weeks. I just bought mine and my husband is going to set it up for me. A lot of people in my rife group are curing themselves this way, Lyme too.
