About 4,000 years ago, the ancient Sumerians stumbled upon an intriguing discovery: they found that scraping the bark off a certain tree and consuming it could make their pain vanish. This discovery laid the groundwork for what we now know as aspirin. The active ingredient in aspirin is found in willow trees and other wild plants, which is why it became part of the medical practices in ancient cultures like Sumer, Egypt, and Greece.
Around 400 BC, Hippocrates, often called the father of modern medicine, suggested chewing willow bark to relieve pain and making tea from willow leaves to ease childbirth pain. However, it took more than 2,000 years before anyone thoroughly investigated its potential. In the mid-18th century, an Englishman named Edward Stone spent five years experimenting and showed that crushed willow bark could reduce fever. About 70 years later, a German pharmacist named Johann Buchner identified and purified the compound responsible for these effects, called salicin. By then, doctors were already using willow bark and other plants rich in salicin, like meadowsweet, to treat pain, fever, and inflammation.
Identifying the exact compound allowed scientists to change its form. In 1853, a French chemist synthesized the compound, creating acetylsalicylic acid. Then, in 1897, the pharmaceutical company Bayer developed a new method and began selling the compound as a pain reliever called aspirin. This was one of the first synthetic pharmaceutical drugs. Originally, aspirin was just Bayer’s brand name, derived from “A” for acetyl and “spir” for meadowsweet, whose botanical name is Spiraea ulmaria. Soon, aspirin became synonymous with acetylsalicylic acid.
As its use spread, aspirin was found to help with not just pain but also inflammation-related issues like rheumatoid arthritis, pericarditis, and Kawasaki disease. Despite its medical benefits, scientists didn’t fully understand how it worked. In the 1960s and 70s, Swedish and British scientists discovered that aspirin interrupts the production of chemicals called prostaglandins, which control pain and inflammation. This breakthrough earned them a Nobel Prize in Medicine in 1982.
Over time, research also uncovered aspirin’s risks. Taking too much can cause bleeding in the intestines and brain and can trigger Reye’s Syndrome, a rare but serious illness affecting the brain and liver in children with infections. By the late 20th century, newer pain relievers like acetaminophen and ibuprofen challenged aspirin’s popularity due to fewer side effects. However, in the 1980s, interest in aspirin surged again. The Nobel Prize winners showed that aspirin slows the production of thromboxanes, chemicals that cause blood clots. A significant clinical trial revealed that aspirin reduced heart attack risk by 44% in participants who took it.
Nowadays, aspirin is prescribed to people at risk of heart attacks or strokes because it reduces the chance of clots forming in the arteries supplying the heart and brain. Additionally, research suggests that aspirin may lower the risk of developing and dying from cancer, especially colorectal cancer. This might be due to aspirin’s ability to decrease levels of a protein that helps cancer cells spread.
These discoveries have transformed aspirin from a simple painkiller into a potentially life-saving treatment. Today, we consume about 100 billion aspirin tablets each year, and researchers continue to explore new uses. Aspirin’s versatility has had a significant impact on modern medicine, which is quite remarkable considering its humble beginnings with willow bark.

4,000 years ago, the ancient Sumerians made a surprising discovery: if they scraped the bark off a particular kind of tree and consumed it, their pain disappeared. Little did they know that this finding would influence the future course of medicine. What the Sumerians had discovered was a precursor to the medicine known today as aspirin. Aspirin’s active ingredient is commonly found in willow trees and other wild plants, which is how it became integrated into the medical traditions of Sumer, ancient Egypt, ancient Greece, and other cultures.
Around 400 BC, Hippocrates, often regarded as the father of modern medicine, first recommended chewing willow bark for pain relief and making willow leaf tea to ease the pain of childbirth. However, it took over 2,000 years for a comprehensive investigation into its potential. In the mid-18th century, an Englishman named Edward Stone conducted five years of experiments, demonstrating that crushed willow bark could alleviate fever. Nearly another 70 years later, a German pharmacist named Johann Buchner identified and purified the compound responsible for these effects, known as salicin. By that time, doctors were already using willow bark and other salicin-rich plants, like meadowsweet, to relieve pain, fever, and inflammation.
Identifying the exact compound opened up the possibility of manipulating its form. In 1853, a French chemist successfully synthesized the compound, creating acetylsalicylic acid. Then, in 1897, the pharmaceutical company Bayer discovered a new method and began marketing the compound as a pain reliever called aspirin. This was recognized as one of the first synthetic pharmaceutical drugs. Originally, aspirin was just Bayer’s brand name, derived from “A” for acetyl and “spir” for meadowsweet, whose botanical name is Spiraea ulmaria. Soon, aspirin became synonymous with acetylsalicylic acid.
As its influence grew, aspirin was found to alleviate not just pain, but also many inflammation-related issues, such as rheumatoid arthritis, pericarditis, and Kawasaki disease. Yet, despite its medical value, scientists still did not fully understand how it worked. In the 1960s and 70s, Swedish and British scientists made significant advancements by demonstrating that the drug interrupts the production of certain chemicals called prostaglandins, which control pain sensations and inflammation. In 1982, this discovery earned the researchers a Nobel Prize in Medicine.
Over time, research has also revealed aspirin’s risks. Overconsumption can lead to bleeding in the intestines and brain and can trigger Reye’s Syndrome, a rare but serious illness affecting the brain and liver in children with infections. In the late 20th century, aspirin’s prominence was challenged by newer pain relievers with fewer side effects, such as acetaminophen and ibuprofen. However, in the 1980s, renewed interest in aspirin emerged due to further discoveries about its benefits. The 1982 Nobel Prize winners also demonstrated that aspirin slows the production of thromboxanes, chemicals that cause platelet clumping, which can lead to blood clots. A landmark clinical trial showed that aspirin reduced heart attack risk by 44% in participants who took the drug.
Today, aspirin is prescribed to individuals at risk of heart attack or stroke because it reduces the likelihood of clot formation in the arteries supplying the heart and brain. Additionally, there is a growing body of research suggesting that aspirin may lower the risk of developing and dying from cancer, particularly colorectal cancer. This effect may be attributed to aspirin’s anti-platelet properties, which could decrease the levels of a certain protein that aids in the spread of cancer cells.
These discoveries have transformed aspirin from a simple pain reliever into a potentially life-saving treatment. Currently, we consume about 100 billion aspirin tablets each year, and researchers continue to explore new applications. Aspirin’s versatility has significantly impacted modern medicine, which is remarkable considering its humble origins in the scraping of willow bark.
