Hydrangea Root (Hydrangea arborescens)


The most common use for hydrangea root is to treat the kidneys and bladder due to its effective diuretic property which helps increase the flow of urine.

Indigenous to the eastern US as far south as Florida, the hydrangea is a woody-stemmed deciduous shrub, growing to a height of about ten feet, producing oval leaves and clusters of small creamy-white flowers, thriving in woodlands and on riverbanks. The root is unearthed in autumn.

The Cherokee used the plant as a remedy for kidney and bladder stones.

The 19th century Physiomedicalist herbal movement used a formula comprising of hydrangea, couch grass, and hollyhock to treat serious kidney disorders, including nephritis.
