Well, I have seen it in my stool. About 2 years ago I was very sick and I really had no idea what was wrong with me until I started investigating. So I decided that I had a severe bout with candida. I didn't see anything in my stool until I started taking herbs to kill the candida. I didn't see any strings but what I did see were chunks of white candida balls in the stool, some big and some small.
