White willow (Salix alba) is a large tree that grows in Central and Southern Europe, Asia, and North America. Also known as European willow or baywillow, this tree prefers to root near streams and rivers and grows to a height of 35–75 ft (11–25 m). In the spring, the slender branches first sprout tiny, yellow flowers and then long, thin green leaves.
White willow belongs to the Salicaceae family. There are over 300 species of willow, but only several species are used medicinally: white willow (S. alba), purple willow (S. purpurea), violet willow (S. daphnoides), and crack willow (S. fragilis).
White willow is the oldest recorded analgesic, or painkiller, in human history. Chinese physicians have used white willow since 500 B.C. to relieve pain and lower fevers. White willow was also used in ancient Assyrian, Egyptian, and Greek medicine as well. The Greek physicians Dioscorides, Hippocrates, and Galen recommended white willow to remedy fevers and pain.

In the mid-1700s, white willow was used in Britain as a remedy for malaria since the bark was similar to cinchona bark, a South American bark used to treat malaria. In 1828, European chemists extracted the constituent salicin from white willow bark and converted it to salicylic acid. At the end of the nineteenth century, acetylsalicylic acid was synthetically produced and aspirin was born. Due to the cheap and easy production of aspirin, white willow eventually lost its popularity as a pain and fever reliever.
In modern times, however, white willow is being recalled as nature's aspirin and gaining popularity around the world as an alternative treatment for fevers and inflammatory and painful conditions such as bursitis, tendinitis, headaches, rheumatoid arthritis, back pain, osteoarthritis, menstrual cramps, and muscle aches. White willow has been approved by the German Commission E for treating fevers, rheumatic ailments, and headaches. In France, white willow is used to remedy headaches, toothache pain, tendinitis, and muscle sprains. The British Herbal Compendium has administered white willow as a treatment for rheumatic and arthritic conditions, colds, and influenza.
