i'm not sure but it would be really good if you could go read some of the last few Bowel Cleanse Forum s. i have learned that most causes for constipation is not enough water... people are dehydrated & dont even know or think they are AND diet of course AND sometimes the bowel muscles have slowed down or stopped working & you need to improve muscle tone (peristalsis) and get the bowels moving on their own without laxatives or lax teas/herbs which do nothing to improve & strengthen the muscles. is good for quick relief but the body needs to eleminate naturally.... a Bowel Cleanse might be good for you... you may have already tried this???? just some thoughts
