I did 2 Hulda ClarkLiver Cleanses (do one every 3 or 4 weeks) and before I did my third liver cleanse I took Barefoot's dewormer for 3 weeks. Then I did a third liver cleanse. I then took the dewormer for 9 more days. I did 6 Liver Cleanses before I began my maintenance program. You may need to do more.
