Juglans regia is native to the region in Eurasia extending from the Near East through to the Himalayas and on to Western China. Walnuts must have been harvested from earliest times but the earliest records of actual growing of orchards of walnut trees go back to classical Greek and Roman times. Besides the nuts, trees are also a source of high-quality wood used for furniture and gunstocks.
Walnut has a long history of folk use in the treatment of cancer. In Chinese traditional medicine, the oil from walnut seeds is used as an application to several kinds of skin diseases, including eczema. A dye obtained from the pericarp of the fruit or from the bark or root may also be used to darken the hair. Walnut leaves and husks preparations have been used in phytotherapy for their astringent and antibacterial properties. The staining power of fresh plant preparations was used for colouring tissues and wool.
