Americans this year will swallow 15,000 tons of aspirin, one of S1.______
safest and most effective drugs invented by man. As the most popular
medicines in the world today, it is an effective pain reliever. Its bad S2.______
effects are relatively mild, and it is cheap.
For millions of people suffered from diseases, it is the only thing S3.______
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, ff relatively mild, S4.______
are largely unrecognized between users. S5.______
Although aspirin was first sold by German company in 1899, it
has been around much longer than that. Hippocrates, in ancient
Greece, understood the medical value of the leaves and tree bark
which today is known to contain salicylates(水杨酸盐), the chemical S6.______
in aspirin. During the 19th century, there was a great number of S7.______
experimentation in Europe with this chemical, and it led in the
introduction of aspirin. By 1915, aspirin tablets were available in the S8.______
United States.
A small quantity of aspirin (two five-grain tablets) relieves pain
and inflammation. It also reduces down fever by interfering with some S9.______
of the body's reactions. Specifically, aspirin seems to slow down the
formation of the acids involved in pain and the complex chemical
reactions that cause fever. The chemistry of these acids is not fully
understood, and the slow effect of aspirin is well known. S10.______
