Constructive critism...but if you dont know what in the heck your talking about...do us all a favor and dont be a dis service speaking non sense...i mean my god. Did u even spend half a second interpreting the guys msg...he HAS LOWER BACK PAIN which his body is saying. HI MY KIDNEYS HURT> pay attention to me. Holy shnikeys. U suggest cleansing the liver?...sweetheart. U gotta clean ur kidneys while cleaning ur bowels...while supporting the liver. Why on earth would u do Liver Flushes if the kidneys are crying...u think they can support a Liver Flush of TOXINS streaming through a burnt out inflammed kidney? Basically...if you dont know...thats ok. Its better to have the blind sit out instead of leading people. thats a DIS-SERVICE.
