I found this last night or so and remember the lines about black stones being dangerous....then to read what you wrote about your husband has me nervous....can anyone tell me if this paragraph is true...I also included the web site as the source. The following paragraph is on the web site about 3/4 down.
******Many people can scarcely believe the kind of stones that come out of them during a thorough liver flush. In actuality, the stones above came from both the liver and gallbladder. Green to bright green stones reflect a relatively healthy liver and gallbladder. Stones that are anywhere from brown to black (almost always foul smelling) reflect a liver that is either in a disease state -- or well on the way. In the photos above, the left is the stool produced by the flush. The right photo was taken after the stool was cleaned - in order to clean off and isolate the stones hidden within the stool. *****
