I recently did a Liver Flush and have not had a "natural" bowel movement since that time. (four days now) Is this normal and should I be concerned?

Thanks for replies

Sometimes the bowels don't move right after the completion of a liver cleanse besause the colon is empty, but after four days you should be working again if you are eating. Enemas are a good first choice. The Physillum and Bentonite shakes are great for getting things moving too. I believe a Bowel Cleanse is a great thing to do between liver flushes.
