If this is the first time you took the Castor Oil concoction, take it again the next time you flush. The last poster was right about it being parasite eggs. The second flush with the concoction will, probably, bring out the adult whatever-baddies. Don't give anything the chance to grow and hatch out again. I had mentioned in aniother post that my son flushed this way one time. But, I am disappointed that he did not follow through on the second flush.
