Scientists use Latin names among themselves to avoid confusion. The Latin name for tree hydrangea is Hydrangea arborescens . Arborescens means ‘tree-like’ and indicates that this shrub can grow as tall as a small tree. That’s why we call it tree hydrangea in Dutch.

Kidney stones

Kidney stones are crystallizations that have formed from substances in the urine. They can be small, then we call them kidney stones. But they can also be as big as a small pearl; that’s a real kidney stone. Usually these problems resolve on their own. But sometimes a person has to discharge kidney stones quite often and this can be a very painful event.

When you consult a naturopath or herbalist, he or she will first determine the cause of kidney stones and then combat current kidney stones with medicinal plants. One of those plants could be tree hydrangea root.

Active substances
