My ND said it could take two years to get rid of parasites of course you will feel better way earlier than that but your trying to end all stages of the life cycle and annilate them but it is still a process I wish there was an easier effective and faster way .I wonder rife will be get it done... Chinese medicine formulas fumigate the body and kill them but it is longer process and way gentler on the system than say Wormwood which my ND says Wormwood it can caused digestive problems by upsetting the flora etc...
