diagnosed with kidney infection-any natural cures?

My grandmother is real stubborn lady. Whatever she thinks that must be done, will be done. By her methods, of course. She was diagnosed with kidney infection last week, but she does not consider taking her medications at all. She thinks that her teas and herbal preparations can cure everything and that is driving me mad, to say at least. How am I to explain her some things about life when she is, like 50 years older than me? So my question concerns people diagnosed with kidney infection, any natural cures?

Actually, you could listen to what older people say from time to time. Your grandmother is right in this case, if it was a mild kidney infection, it could be treated with some herbal medications. Cranberry juice helps in dissolving the bacteria attached to cells, for example. There are even some other ways of treating this conditions, some use reflexology, aromatherapy etc.
