American this year will swallow 15, 000 tons drugs of

aspirin, one of safest and most effective invented by man. 【M1】__

The most popular medicines in the world today, it is an el- 【M2】__

fective pain reliever. Its bad effects are relatively mild, and it

is cheap.

For millions of people suffered from arthritis, it is the 【M3】__

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 between chil-【M4】__

dren. It has side effects that, if relatively mild, are largely 【M5】__

unrecognized among users.

Although aspirin was first sold by a German company

in 1899,it has been around more longer than that. Hippocra-

tes, in ancient Greece, understood the medical value of the

leaves and tree bark which today are known to contain salic- 【M6】__

ylates(水杨酸盐), the chemical in aspirin. During the 19th

century, there was a great number of experimentation in Eu- 【M7】__

rope with this chemical and it led in the introduction of aspi-

rin. By 1915, aspirin tablets were available in the United 【M8】__

States.

A small quantity of aspirin (two five - grain tablets)

relieves pain and inflammation. It also reduces down fever 【M9】__

by interfering with some of the body’s reactions. Specifical-

ly, aspirin seems to slow down the formation of the acids in-

volved in pain and the complex chemical reactions that

cause fever. The chemistry of these acids is not fully under-

stood, and the slowing effect of aspirin is well known. 【M10】__
