she must take an aspirin.句中的吃为什么不用eat

Americans this year will swallow 15,000 tons of aspirin, one of the safest and most effective drugs invented by man. The most popular medicine in the world today, it is an effective pain reliever. Its bad effects are relatively mild and it is cheap.
For millions of people suffering from arthritis(关节炎), it is the only thing that works. Aspirin, in short, is truly the 20th-century wonder drug. It is also the second largest suicide drug and is the leading cause of poisoning among children. It has side effects that, although relatively mild, are largely unrecognized among users.
Although aspirin was first sold by a German company in 1899, it has been around much longer than that. Hippocrates, in anc ient Greece, understood the medical value of the leaves and tree bark which today are known to contain salicylates(水杨酸碱), the chemical in aspirin. During the 19th century, there was a great deal of experimentation in Europe with this chemical, and it led to the introduction of aspirin. By 1915, aspirin tablets were available in the United States.
A small quantity of aspirin (two five-grain tablets) relieves pain and inflammation(炎症). It also reduces fever by interfering with some of the body’s reactions.

People have known since ancient times that aspirin（阿司匹林） reduces pain and lowers high body temperature. But that is not all the drug can do. In recent years, it has been used in other ways, too. Small amounts may help prevent a stroke or heart attack. One recent study showed that some people who took two aspirin pills a day had lower rates of colorectal cancer. And, some researchers say aspirin may help patients with colon cancer live longer. So, how did aspirin become so important? The story begins with a willow（柳树）．
2, 000 years ago, the Greek doctor Hippocrates advised his patients to chew on the bark and leaves of the willow. The tree contains a chemical called salicin. In the 1800s, researchers discovered how to make salicylic acid from the chemical. In 1897, a chemist named Felix Hoffmann at Friedrich Bayer and Company in Germany created acetyl salicylic acid. Later, it became the active substance in a medicine that Bayer called aspirin. The "a" came from acetyl. The "spir" came from the spirea plant, which also produces salicin. And the "in" ? That is a common way to end medicine names.
In 1982, a British scientist shared the Nobel Prize in Medicine in part for discovering how aspirin works. Sir John Vane found that aspirin prevents the body from making the natural substances called prostaglandins. Prostaglandins have several effects on the body. Some cause pain and swelling（肿）． Prostaglandins also make the heart, kidneys(肾) and blood vessels work well. So there is a problem. Aspirin works against all prostaglandins, good and bad. It can also harm the inside of the stomach, and sometimes it can cause bleeding.
But a British study released in 2009 suggested that taking another drug with a small amount of aspirin may help reduce the risk of bleeding. If this proves true, it would help thousands of people who are seeking to prevent life-threatening conditions.
