You should realize that you are not alone. There are many people that do not realize the harmful effects that the Senna,Cascara Sagrada and Psyllium Seed Husks can have on your intestinal system. The product that I have used for the last 3 years is called Oxypowder . This product is an oxygen based intestinal cleanser. I have talked to their customer service on several occasions and the people there are very knowledgeable about the harmful effects of the herbal laxatives that many people take to relieve their constipation. However, many people do not realize that these types of products do not actually address the root cause of constipation. These products act as a band aid and does not actually help your body to rid itself of the toxic material that is the actual problem.
I hope this helps you to realize your goals to a healthier and happier you.
