The Activlink Gold system uses safe and proven hypnosis technology to treat the causes and symptoms of Irritible Bowel Syndrome, Crohn's Disease and other auto immune diseases. Research shows that auto immune diseases are due to untreated anxiety and stress causing an over-active sympathetic nervous system response. Each Activlink Gold system includes an Activlink hypnosis CD, a special Activlink Vibralite triggered-suggestion wristwatch, and Quickstart Guide. Try the Activlink Gold system as directed for at least 30 days, and if you do not have a noticeable decrease in symptoms, we will gladly refund your entire purchase price when you return the system.
