Not necessarily. You can have small stones in either the liver, gallbladder or bile ducts, but bile still makes its way out. A healthy liver produces about a quart of bile a day... it's got to go somewhere!!
Liver Flushing is a wonderful part of a cleansing program. It is recommended to flush every two weeks until many stones have been passed--it took 4-5 flushes in my case before I passed a potty load of beautiful jade green stones the size of small prunes! After that I never had a moment of trouble with my skin--constantly plagued with adult Acne for YEARS before that--and my digestion has never been better!
I will be doing a maintenance flush after the break next week. DO check out the excellent and very supportive Liver Flush Forum here at curezone with all the info.
