I did my first flush Saturday also! Passed a lot of round small stones. I was wondering if anyone has had blood pass through after a flush. At first I thought it was the red beets I ate, but it's been 4 days now. I wonder if the stones cause any tearing. I have 3 more flushes to go in the next few months. I am using the great Chinese Herbs before the flush. They have been a godsend.
