Blessed Herbs , in my opinion and vast experience with Humaworm , Colonix and every cleanse known to man, is the BEST. If you are dealing with parasites, lyme, etc it is an amazing product. I would recommend doing this twice in a row. I would also recommend not even going NEAR Humaworm products. They make everything worse if you have multiple issues. No Black-Walnut or Wormwood in the Colon Cleanse from Blessed. Believe me, thats a good thing. Those are very damaging herbs IMO.
