What can anyone tell me about Hydrangea, Gravel Root and Marshmallow?

I was diagnosed with a kidney stone. This is miserable. I am taking Vicodin now for pain, drinking a gallon of water and hoping this passes. In talking to a naturopath the above were suggested. Can anyone tell me if the above truley works? I'd like relief. Next stop is Lithotripsy which frankly scares the hell out of me.

Thanks a head of time.



Oh and one more thing. I take atentolol and flecainade for Afib, my other concern will these herbs conflict with the meds I am taking. I have calls into my cardiologist as I type.
