i'm on day 26 of Master-Cleanse and have been doing a parasite/worm cleanse since Day 6. I went to the health store looking for Wormwood , clve and green Black-Walnut hull---Clark's prescription. The clerk at the health food store asked "Do you want the 'Worm parasite Cleanse'. It has all three of her ingredients, it was less than $15 (clark's is $45) and it worked. By day 8 I was visibly passing clear, 1/2" worms. I added a dropper full into my limeade four or five times a day. I've continued it daily (i'm on my 2nd bottle) to make sure I zap all invisble paraites. The product I bought is by Quantum Health. Good luck. I plan to do the Liver Flush after my 40 days.
