Weeping Willow Pussy Willow stage 2 Pussy Willow stage 3 Willow Oak
Description - The willows are deciduous trees and shrubs in the genus Salix, part of the willow family Salicaceae. There are about 350 species in this genus worldwide, found primarily on moist soils in cooler zones in the Northern Hemisphere. The leaves are deciduous, often elongate but round to oval in a few species, and with a serrated margin. Willows are dioecious with male and female flowers appearing as catkins on different plants; the catkins are produced early in the spring, often before the leaves or as the new leaves open. The fruit is a small capsule containing numerous tiny (0.1 mm) seeds embedded in white down, which assists wind dispersal of the seeds. Willows are very cross-fertile and numerous hybrids are known, both naturally occurring and in cultivation.

History - The active extract of the bark, called salicin, was isolated to its crystalline form in 1828 by Henri Leroux, a French pharmacist, and Raffaele Piria, an Italian chemist, who then succeeded in separating out the acid in its pure state. Salicin is acidic when in a saturated solution in water (pH = 2.4), and is called salicylic acid for that reason.
Pharmacology - In 1897 Felix Hoffmann created a synthetically altered version of salicin (in his case derived from the Spiraea plant), which caused less digestive upset than pure salicylic acid. The new drug, formally Acetylsalicylic acid, was named aspirin by Hoffmann's employer Bayer AG. This gave rise to the hugely important class of drugs known as non-steroidal anti-inflammatory drugs (NSAIDs). The inner bark and leaves of many willows contains the medicinal extract, salicin, or salicylic acid (salix is Latin for willow). This chemical is the active ingredient in common aspirin. (acetylsalicylic acid). Native Americans chewed or boiled a tea from the willow's leaves or inner bark to relieve fever or other minor pain like toothaches, headaches, or arthritis. The willow is often given the nickname "toothache tree".
Medicinal Uses - Aspirin (Acetylsalicylic acid) suppresses the production of local hormones known as prostoglandins. These are found in most tissues of the body, and they have a number of different functions including regulating the contraction of the so-called "smooth" muscle that is found in the blood vessels, the stomach, the intestines and the bladder, and mediating pain and inflammation. But they also regulate the aggregation of platelets — scraps of cells in the bloodstream that help to form clots. Suppress the prostoglandins in platelets, therefore, and you suppress the formation of the sort of clots that trigger heart attacks and strokes.
