I have been researching the issue of yeast and mercury - primarily because I felt so bad when doing this parasite cleanse. I found out that the yeast actually acts as a defense for us - yeast binds to the mercury so when you kill the yeast the mercury escapes and causes more symptoms. When I first started this cleanse I felt horrible - mainly I think because I was killing parasites (no doubt I have a problem there) and killing yeast which was causing mercury symptoms to be worse. I have decided that for me - I am now treating the parasite issue which will probably kill some yeast too but only using the tincture will help significant yeast die off - no garlic for me right now because it will kill more yeast (I know it kills parasites too but I get results from the tincture alone) then I will deal with the mercury - when you remove the mercury the yeast will subside significantly and then when mercury is controlled combat yeast in the end. If you are mercury poisoned you have yeast - if you keep killing the yeast but still have mercury you will keep getting yeast - diet or no diet, antifungals or no antifungals. I do agree to keep a very low sugar healthy diet - veggies and protein with little fruit. It is all in moderation and time. This is just my thought.
