The sandy stuff is what they call "chaff" or "sand", and it is dead eggs and worm droppings. The fuzzy balls are probably candida. They look like little cotton balls with baby worms sticking out of them. The herbs are in your bloodstream and continue to work for up to 30 days after the cleanse is over. If you're seeing those candida balls, it might be best to do a candida cleanse next. I'll let Dr. Bailey say for sure, but that's what she recommended for me.
