i had kidney stones and i tried Uriflow which is an herbal product and it flushed out my stones in 5 days. it also helps with the pain, where as before i tried Uriflow, i also gave Lithonal a shot. but to my surprise, that is the worst product ever. these people are scams and they have chemical added to their product.
and they also charge for shipping.
May god bless the founders of Uriflow.
