"Candida is a microscopic yeast. So I don't know what you see. Maybe a Tapeworm or just some indigested food and fibers."
You are giving misinformation to this person. Candida overgrowth is indeed very real, and I and many others have had the experience of purging threads and clumps of candida FUNGUS after enemas, etc. Candida's yeast and FUNGUS forms are two totally different organisms. There is tons of information on this site from many people who have done tons of research; please read it.
