The story of the discovery of aspirin stretches back more than 3500 years to when bark from the willow tree was used as a pain reliever and antipyretic. It involves an Oxfordshire clergyman, scientists at a German dye manufacturer, a Nobel Prize-winning discovery and a series of pivotal clinical trials.
Does aspirin come from the Aspen tree?
QUAKING ASPEN The major chemical in this tree, salicin, is found in the bark. When salicin is in the body it converts to salicylic acid, a common ingredient of aspirin. A preparation of Aspen was often used for headaches and fevers. We still use aspirin today for everyday aches and pains.
Does aspirin come from birch trees?
It is a common misconception that aspirin is found in the bark of the willow tree. A related compound called salicin does indeed occur in willow bark, thereby explaining the use of the bark as a medication since the time of Hippocrates.
What kind of willow tree makes aspirin?
The bark of white willow contains salicin, which is a chemical similar to aspirin (acetylsalicylic acid). In combination with the herb’s powerful anti-inflammatory plant compounds (called flavonoids), salicin is thought to be responsible for the pain-relieving and anti-inflammatory effects of the herb.
Where does aspirin come from naturally?
History of aspirin It comes from Spiraea, a biological genus of shrubs that includes natural sources of the drug’s key ingredient: salicylic acid. This acid, resembling what’s in modern-day aspirin, can be found in jasmine, beans, peas, clover and certain grasses and trees.
Are birch and aspen trees the same?
Although aspen are somewhat similar in appearance to some species of birch, birch trees belong to an entirely different family of trees. Birch are famous for having bark that peels back like paper; aspen bark does not peel.
Why do willow trees produce salicylic acid?
Although components of willow bark include flavonoids and tannins, its pain-relieving properties are attributed to the salicin glycosides present in the compound. After ingestion of willow bark, the salicin glycosides are converted in the intestine to saligenin, which is then metabolized to produce salicylic acid.
Why do willow trees have salicin?
The salicin inside willow bark works the same way as aspirin, by reducing inflammation and pain as it enters your bloodstream. Because of the anti-inflammatory properties of willow bark, it may be especially effective in combatting joint pain as well.
Is there wood in aspirin?

In 1897, Felix Hoffman, a German chemist working for the Bayer company, was able to modify salicylic acid to create acetylsalicylic acid, which was named aspirin (Fig. 1).
What are aspirins made of?
Aspirin is prepared by chemical synthesis from salicylic acid, through acetylation with acetic anhydride. The molecular weight of aspirin is 180.16g/mol. It is odourless, colourless to white crystals or crystalline powder.
How can you tell birch from poplar?

Betula spp (birch) bark, though in the separate Betulaceae family, has similar salicylate constituents to willow and aspen, and can also be used interchangeably with these two. It is historically considered to have more of an affinity with the genitourinary tract.
