Yes homeopathy helps. If you are interested buy following
two homeopathic remedies. (1) Urtica Urens 200 – 15 gms.
pills and (2) Berberis Vul 200 – 15 gms. pills. Consume
5 pills of remedy one half an hour after your meals and
15 minutes later 5 pills of remedy two. Remember to
consume after breakfast, lunch and supper i.e. 3 times a
day. By the time the pills get over which will take about
a month and a half you will have your stone passed. Then
have yourself screened which will be valid proof that the
stone has been dissolved. Good luck and God bless.
Cheers! )

The best thing to do is to prevent them from occurring (which i realize is kinda hard after they are already there) – you can do this through making lifestyle and dietary changes! After you have stones you can use herbs to break up the stones One product from a professional company which produces pharmaceutical quality supplements (company is AOR) is called “Chanca Piedra” and has been shown to be effective in breaking down kidney stones. Also some homeopathics can be effective. You might want to consider going to see a registered Naturopathic Doctor that can guide you in breaking up the stones and then making some necessary changes to help prevent them from reoccurring!!
