I started on Earth Friend's Fungus-Ease after contracting a chronically runny nose from a fungal home environment. I know that, historically, I am prone to fungal and yeast infections, so I was not happy. (I had muscle-tested positive for fungus, plus I could smell it in my sinus.) I cleaned out the home environment, but without resolution to my sinus. Within three days of using the tincture, I could notice an improvement, and within a week and a half of the tincture, I was all better. Sylvia Skefich, D.C., Santa Cruz, CA
