To get the best results choose one of the health promoting programs which include a parasite program, kidney cleanse and /or apple juice to soften stones and whatever detox methods you can afford and then the liver/gall bladder flush. I have used Hulda Clark 's programs for years. In looking at her book " The Cure For All Diseases " she recommends -for Acne - doing a parasite program and staying on the herbs until the Acne is improved and then continuing a lower dose of the herbs weekly. She found the parasite, Trichinella in all but one of her Acne patients. She also advised detox for several pollutants people had acquired - so choose a detox program which gets out a variety of toxins.
