STORY HIGHLIGHTS

(CNN) -- If you lot take aspirin, you've got a pain reliever, heart attack preventer and possible cancer preventer rolled into one tablet. You lot might recollect that whoever invented aspirin is a genius, only the truth is humans take been using its natural equivalent for thousands of years.

"Aspirin is one of those things that, long earlier at that place were ever clinical trials or whatever kind of scientific knowledge, people figured out, 'Hey, I feel better when I take this substance,' " said Dr. Karol Watson, assistant professor of cardiology at the David Geffen School of Medicine at the Academy of California, Los Angeles.

The drug has been making headlines considering a study in the Lancet recently constitute that a daily aspirin appeared to lower the risk of cancer by at least twenty% during a 20-year period. That's based on data from more than 25,000 patients and builds on earlier findings that aspirin may lower the gamble of colorectal cancer. The research has limitations and is not definitive proof, but it does add together another benefit to an aboriginal remedy that has been called a miracle drug.

"There are no countries in which information technology is unknown, unappreciated, or unavailable," the late medical writer Berton Roueché wrote in 1955, in an article after published in the anthology "The Medical Detectives."

History of aspirin

The word "aspirin" wasn't a coincidence. It comes from Spiraea, a biological genus of shrubs that includes natural sources of the drug'southward key ingredient: salicylic acid. This acrid, resembling what's in modern-day aspirin, can be found in jasmine, beans, peas, clover and certain grasses and copse.

The ancient Egyptians used willow bawl equally a remedy for aches and pains, said Diarmuid Jeffreys, writer of "Aspirin: The Remarkable Story of a Wonder Drug." They didn't know that what was reducing trunk temperature and inflammation was the salicylic acid.

Hippocrates, the Greek physician who lived from about 460 to 377 B.C., wrote that willow leaves and bark relieved pain and fevers.

Information technology wasn't until thousands of years later that people began to isolate the primal ingredients of aspirin. An 18th-century clergyman, Edward Stone, rediscovered aspirin, in outcome, when he wrote a study most how a preparation of powdered willow bawl seemed to benefit 50 patients with ague and other maladies, Roueché wrote.

In the 1800s, researchers across Europe explored salicylic acrid. French pharmacist Henri Leroux isolated it in 1829, Roueché writes. Hermann Kolbe discovered constructed salicylic acid in 1874, but when administered oft in big doses, patients experienced nausea and airsickness, and some even went into a blackout. A buffer was needed to ease the effects of this acrid on the breadbasket.

The aspirin we know came into being in the late 1890s in the form of acetylsalicylic acid when chemist Felix Hoffmann at Bayer in Germany used information technology to alleviate his father'due south rheumatism, a timeline from Bayer says. Beginning in 1899, Bayer distributed a pulverisation with this ingredient to physicians to give to patients. The drug became a hitting and, in 1915, information technology was sold as over-the-counter tablets.

One patient who should not have been taking aspirin was young Alexei Nicholaevich Romanov of Russia, who had hemophilia. Aspirin would make the bleeding in this disorder worse, simply the imperial doctors probable gave the male child this new wonder drug without knowing, Jeffreys said.

Alexei, son of the concluding arbiter, probably improved because the mystic Grigori Rasputin told the boy's mother to stop modern treatments and instead rely on spiritual healing. Rasputin's influence on the Romanov family may take contributed to the uprising against them, making aspirin a possible histrion in their murder and in the end of czarist Russia.

Aspirin's uses for eye patients came to light in 1948 when California doctor Dr. Lawrence Chicken recommended an aspirin a day to reduce center assail risk, based on what he had observed in patients.

The Nobel Prize in medicine in 1982 was awarded to researchers who demonstrated the reason -- it inhibits production of hormones called prostoglandins. Prostoglandins are responsible for the formation of clots that leads to heart attacks and strokes, and aspirin prevents that clotting from happening.

Toward better preventative medicine

Today, aspirin is universally recognized as heart-attack prevention in men who take had prior centre attacks, and it has also shown to have benefits against stroke in women.

More than one-third of all adults, and four out of five people with centre affliction, apply aspirin regularly, according to information from the Centers for Disease Command and Prevention presented in a 2006 report. And the number of regular aspirin users rose 20 percent from 1999 to 2003.

All the same, it's not necessarily the get-to for over-the-counter painkillers. In 2007, pain relievers such as Advil, Tylenol and Aleve were amid the top five analgesics sold; aspirin did not make the cutting.

"If you're pain, you're going to achieve for a stronger hurting reliever," Watson said. "In most cases, a babe aspirin a day is not going to make you feel whatsoever ameliorate or worse."

The U.S. Preventive Services Task Forcefulness recommends that men 49 to 79 have aspirin to prevent heart attack, and that women 55 to 79 take it to guard against ischemic strokes, when the potential benefits outweigh the potential harms from an increase in gastrointestinal hemorrhage. In other words, aspirin can increase bleeding because of decreased clotting, so if you have haemorrhage issues, information technology'due south not a good idea.

People who need to take aspirin because of prior heart attack can reduce the take chances of stomach bleeding by taking a medication that cuts down on stomach acid like omeprazole (Prilosec), said Dr. Harvey Simon, associate professor of medicine at Harvard Medical School. Still, "nosotros don't like people to take medicine to reduce effects of another medicine," he said.

Aspirin'southward potential cancer benefits have come on the scene more recently, and there aren't standard guidelines in that regard. The agency discourages taking aspirin to prevent colorectal cancer in people with average take chances for that disease. Besides, the mechanism isn't entirely understood, although the thought is that aspirin helps the body cut off blood supply to cancer growths, Jeffreys said.

Aspirin is in the family unit of nonsteroidal anti-inflammatory drugs (NSAIDs), many of which have been implicated in heart take chances rather than prevention. Among the NSAIDs, the more potent pain relievers tend to carry more potential for cardiovascular damage, Watson said.

Famously, the drug rofecoxib (Vioxx) was withdrawn from the marketplace in 2004 because of heart concerns. A recent written report found that painkillers called opioids heightened heart attack take a chance in addition to os fracture when compared with patients taking NSAIDs such equally aspirin and ibuprofen. And research published in June constitute that some NSAIDs may increase hazard of cardiovascular death.

Aspirin has a lot of cheerleaders, merely information technology'due south important to keep the downsides in perspective. Dr. Scott Fishman, primary of pain medicine at the Academy of California, Davis, points out that equally a pain reliever, aspirin'southward effects are potent merely brusque-lived. The way that aspirin inhibits enzymes in the stomach can lead to ulcers, which can exist especially harmful in combination with decreased clotting.

The drug works as a pain reliever considering it blocks an enzyme that's required for the process of inflammatory response, he said.

Patients should non simply take it without consulting their physicians, Fishman said. Certain conditions such every bit bleeding disorders make taking aspirin dangerous. Some supplements, such as fish oil and garlic, can also cause bleeding problems in combination with aspirin, he said. Aspirin is not approved for children younger than 2 and should be used with caution in very young people because of a possible link to Reye's syndrome.

Withal, it'southward probable that aspirin has fifty-fifty more benefits that simply haven't been discovered yet, Jeffreys said. In his view, the drug is taken for granted, and non enough accent is placed on it.

"If I'g stranded on a desert island, and I tin can take one drug with me, that's the i I'm taking," Watson said.
