Help John with Kidney Herbal Medicine

Hi my name is John and I'm fundraising for herbal medicine for my failing kidney. I only have one kidney and Doctors have said that it is in the 5th stage of failure. Doing research we have found an alternative option to my kidney failure and that is herbal medicine from Japan, the cost for this medicine is high and Insurance wont help cover it. If anyone can help I will for ever be grateful.
