Salix alba, the white willow, is a species of willow native to Europe and western and central Asia. It is a medium-sized to large deciduous tree growing up to 10–30 m tall. The bark is grey-brown, and deeply fissured in older trees. The shoots in the typical species are grey-brown to green-brown. The leaves are paler than most other willows, due to a covering of very fine, silky white hairs, in particular on the underside; they are 5–10 cm long and 0.5–1.5 cm wide. The flowers are produced in catkins in early spring, and pollinated by insects.
Willow bark can be used as medicine to ease aches and pains and reduce fevers. The extract is used in cosmetics and personal care products for its astringent, anti-inflammatory, soothing and conditioning properties.
