A precursor to aspirin found in the bark of the willow tree (genus Salix) has been used for its health effects for at least 2,400 years. [11] [12] In 1853, chemist Charles Frédéric Gerhardt treated the medicine sodium salicylate with acetyl chloride to produce acetylsalicylic acid for the first time. [13]
The bark of white willow contains salicin, which is a chemical similar to aspirin (acetylsalicylic acid). It is thought to be responsible for the pain-relieving and anti-inflammatory effects of the herb. In 1829, salicin was used to develop aspirin. White willow appears to be slower than aspirin to bring pain relief, but the analgesia may last ...
Salicin from meadowsweet was used in the synthesis of aspirin (acetylsalicylic acid), [6] in 1899 by scientists at Bayer. Salicin tastes bitter like quinine. [7] Salicin may cause an allergic skin reaction (skin sensitization; category 1). [3] Mild side effects are standard, with rare occurrences of nausea, vomiting, rash, dizziness and ...
Bartram's 1998 Encyclopedia of Herbal Medicine [7] is perhaps typical when it states, 'in 1838 chemists identified salicylic acid in the bark of White Willow. After many years, it was synthesised as acetylsalicylic acid, now known as aspirin.' It goes on to claim that willow extract has the same medical properties as aspirin, which is incorrect.
White willow: Plant source of salicylic acid, white willow is like the chemical known as aspirin, although more likely to cause stomach upset as a side effect than aspirin itself which can cause the lining of the stomach to be destroyed. Used from ancient times for the same uses as aspirin. [132] Salvia officinalis: Sage
William Turner, in 1597, repeated this, saying that willow bark, "being burnt to ashes, and steeped in vinegar, takes away corns and other like risings in the feet and toes". [31] Some of these cures may describe the action of salicylic acid, which can be derived from the salicin present in willow. It is, however, a modern myth that Hippocrates ...

Willow bark (from trees of the Salix genus) was widely known to be used as a medicine by multiple First Nations communities. [162] The bark would be chewed or steeped in water for its pain relieving and antipyretic effects. The effects are a result of the bark's salicin content.
