If u can find a natural health store nearby see if they have this... Chanca Piedra also goes by "breakstone'. I got a 1.5oz bottle for $28. Its the kind of stuff u put under ur tongue. I had a stone killing me, went to the E.R., whole 9 yds. Stopped and got this bottle, put 3 drops under the tongue and i swear within 1 mile of leaving that store the pain went away and ive never had it again. Coincidence maybe but all i can tell you is it worked for me..
