White Willow


White Willow

In this genus there are about 300 species of deciduous trees and shrubs, which occur worldwide, except in Australia. Salix alba (white willow) is a common tree in wetlands and near watercourses. It is less often planted in gardens than its varieties. It is less often planted in gardens than its varieties, which have colorful bare stems in winter. Though sometimes labeled S. alba 'Tristis', the familiar golden weeping willow is a hybrid, more correctly known as S. x sepulchralis var. chrysocoma. The willow was also once regarded as a symbol of grief: garlands of the leaves were worn by those deserted by their loves. In parts of England, sprays of willow are woven into crosses at Easter. Willow bark was described by Dioscorides (first century CE), as a remedy for relieving pain and lowering fever, and long before this it is mentioned on clay tablets of the Sumerian period (4th millenium BCE) as an anti-rheumatic. It contains salicylic acid, which was first synthesized in 1838 and provides the basis for aspirin. Various other species, including S. cinerea (gray willow), S. fragilis (crack willow), the American S. nigra (black willow), S. pentandra (bay willow) and S. purpurea (purple osier), are used interchangeably with S. alba for medicinal purposes. Several other species were used by native N Americans, who drank strong willow-bark tea to induce sweating as a cure for fever. In S Africa, S. mucronata is similarly used to relieve fever and rheumatism.

Long before aspirin was found in every medicine chest, people with headaches or other painful conditions reached for the bark of the white willow tree. Known as nature's aspirin, white willow bark contains salicin, a chemical cousin of the popular pain reliever. Like aspirin, salicin quells pain, fever, and inflammation but does not keep the blood thin and help protect against heart attacts.

Large tree with deeply fissured, gray-brown bark, ascending branches, and lanceolate, tapering leaves, to 10cm (4in) long. Flowers appear as yellow male catkins, to 5cm (2in) long, and stalkless, yellow-green female catkins, 3cm (1¼in) long, with the new leaves in spring.

History:
The first century CE Greek physician Dioscorides was among the first to praise white willow's superior effectiveness in treating fevers, inflammations, and pain. Two thousand years later, native healers, herbalists, and mainstream physicians still use white willow—albeit in different forms—to treat these same conditions. White willow is one of nature's "natural" aspirins—like meadowsweet and wintergreen—which are rich in salicylates from which commercial aspirin is made. Meadowsweet (Filipendula ulmaria) was the first of these herbs to contribute to the discovery and synthesis of salicyclic acid (aspirin), but it was the willow family that was named (Salix), specifically for its powerful pain-relieving ingredient. White willow, a native of Europe, has been naturalized in the United States for almost 400 years. It is a much prized, elegantly beautiful tree, and it may come as a surprise—given the joy and peace both its beauty and medicine provide—to learn that the willow tree has long been a symbol of deep mourning and despair. In earlier times, garlands made from the tree's leaves were worn by individuals who had been abandoned by their lovers.
