Native to the eastern United States of America, sourwood is characterised by its majestic foliage and fragrant lily of the valley-like flowers in springtime. Its young leaves are highly prized in traditional medicine for their refreshing and diuretic properties. It is also much admired for its ornamental qualities especially in Autumn when it puts on a spectacular display.
The sourwood extract used by Clarins Laboratories helps to protect and strengthen skin fibres.
