Welcome to curezone. Curezone details all of the cleanses that are recommended for improving health. The idea is to work your way up to the very effective liver flush, and in most cases, a series of Liver Flushes will dramatically improve your health. Since you are in your fifities, you probably need to cleanse the bowel first over a few weeks, either with colonic irrigation or Oxypowder . All humans are infested with parastes so don't feel alone. The purpose of cleansing is to dramatically reduce your infestation. I would commence taking Diatomaceous Earth (silica) asap. This will dramatically improve your health.
