In reply to your question.I would suggest you follow Dr Clark's regime.It is tried and tested and it has made a great difference to me so far.I have had ME [CFS]for over 20 years.I did the paracite cleanse [Black Walnut/Wormwood/Cloves] for one month before I did anything else.Then the Teeth clean up/kidney cleanse[Herbs in the book I can't remember them] bowl cleanse of Tumeric,Fennel,Senna or Cascara [another month],and then on to the Liver Cleanses every 2 weeks.I have now done 6 Liver Cleanses and have got liver flukes and worm eggs out.I did it exactly as in Dr Clark's book ' The Cure For All Diseases 'as I had been so ill,and she says that if you do the cleanses in the correct order,it will not make you worse.The only adverse effect was some nausia whilst doing the Liver Cleanses.Its not expensive,and it has been the best therapy I have done so far and I have spent thousands of pounds on trying to get well.Deotima
