The white stones on ultrasound does not mean that they are calcified. Mine showed up white on ultrasound too. It's if they show up on x-ray (without iodine) that they're calcified.
How were you able to talk to someone on rain-tree. Are you supposed to take the chanca piedra alone for a while and then the mixture, or did he say to only take the chanca piedra. Do you know how long you're supposed to take it? Take Care
