Public Description:

Salix alba subsp. alba, commonly known as “white willow”, is native to Europe and western and central Asia. The name "white willow" in all three languages, Turkish, English and Latin, comes from the fact that the lower surface of the leaves is white. It is a deciduous tree that grows about up to 30 m tall. The wood is tough, strong, and light in weight, but has minimal resistance to decay. On the other hand, the white willow is fast-growing, but relatively short-lived, being impressionable to several diseases.In ancient texts from the Assyrian, Sumerian and Egyptian civilizations, it was mentioned that the leaves and barks of the willow tree were used as analgesic and antipyretic. In ancient Greece, in the fifth century BC, Doctor Hippocrates wrote the medical characteristics of the willow. The main ingredients of Aspirin, "salicin and methyl salicylate" are derived from members of this genus (Salix L.). These properties are the strongest in the inner bark of the trees, but they are also present in the leaves. Like aspirin, the willow family is used in the treatment of fever, headache, arthritis and inflammatory conditions, especially in the urinary tract. Willow wood is widely used in making furniture and wooden tools. In addition, baskets, fish traps, wattle fences and wattle and daub house walls, were often woven from osiers or withies. Willow trees are also used for activities such as biological filtration of wetlands, ecological wastewater treatment systems, soil remediation, landscaping and soil erosion control.
