Hydrangea Root (Hydrangea arborescens) increases the flow of urine and will remove bladder stones and the pain caused by them. It is helpful in preventing the formation of gravel and will help deposits pass through the ureters from the kidneys to the bladder. Hydrangea will also relieve the backache caused by kidney troubles. Its effectiveness is due to its alkaloids that behave like cortisone without the deleterious side effects. Hydrangea works wonderfully for those with severe rheumatism. It also helps correct bedwetting in children.
