The sad truth is that stupid articles like that cause people to suffer a lot more than they need to. Not doing the flushed and cleanses shortens your life and increases your risk of needing surgery.
More unsubstantiated claims.
But since you brought up surgery why don't you mention that "liver flushing" can cause real gallstones to lodge in a duct leading to pancreatitis and requiring emergency surgery? Funny how the "liver flush" supporters never warn people of this real danger.
