You might not have good results from your Liver Flush because you didn't do a parasite cleanse. Since you have a self-proclaimed parasite problem that makes me even more apt to blame the parasites. Dr. Hulda Clark states that you can't cleanse a liver with living parasites in it. I think you can, but you won't get as many stones as evidenced by your results.
Flush again and again as long as your not getting sick from it. Do you have an allergy to the cloves, Black-Walnut hulls and Wormwood ? If so, I would just cleanse w/out the parasite cleanse. Keep on flushing!
http://www.drclarkstore.com/parasite-program.html has some new parasite cleanse cleanse you might want to check out. Maybe this spice syrup parasite cleanse will have less ingredients you react to.
