The history of aspirin is a product of a rollercoaster ride through time, of accidental discoveries, intuitive reasoning and intense corporate rivalry.
In the opening pages of Aspirin: The Remarkable Story of a Wonder Drug, Diarmuid Jeffreys describes this little white pill as ‘one of the most amazing creations in medical history, a drug so astonishingly versatile that it can relieve headache, ease your aching limbs, lower your temperature and treat some of the deadliest human diseases’.
Its properties have been known for thousands of years. Ancient Egyptian physicians used extracts from the willow tree as an analgesic, or pain killer. Centuries later the Greek physician Hippocrates recommended the bark of the willow tree as a remedy for the pains of childbirth and as a fever reducer. But it wasn't until the eighteenth and nineteenth centuries that salicylates the chemical found in the willow tree became the subject of serious scientific investigation. The race was on to identify the active ingredient and to replicate it synthetically. At the end of the nineteenth century a German company, Friedrich Bayer & Co. succeeded in creating a relatively safe and very effective chemical compound, acetylsalicylic acid, which was renamed aspirin.
The late nineteenth century was a fertile period for experimentation, partly because of the hunger among scientists to answer some of the great scientific questions, but also because those questions were within their means to answer. One scientist in a laboratory with some chemicals and a test tube could make significant breakthroughs whereas today, in order to map the human genome for instance, one needs ‘an army of researchers, a bank of computers and millions and millions of dollars’.
But an understanding of the nature of science and scientific inquiry is not enough on its own to explain how society innovates. In the nineteenth century, scientific advance was closely linked to the industrial revolution. This was a period when people frequently had the means, motive and determination to take an idea and turn it into reality. In the case of aspirin that happened piecemeal - a series of minor, often unrelated advances, fertilized by the century’s broader economic, medical and scientific developments, that led to one big final breakthrough.
The link between big money and pharmaceutical innovation is also a significant one. Aspirin's continued shelf life was ensured because for the first 70 years of its life, huge amounts of money were put into promoting it as an ordinary everyday analgesic. In the 1970s other analgesics, such as ibuprofen and paracetamol, were entering the market, and the pharmaceutical companies then focused on publicizing these new drugs. But just at the same time, discoveries were made regarding the beneficial role of aspirin in preventing heart attacks, strokes and other afflictions. Had it not been for these findings, this pharmaceutical marvel may well have disappeared.
So the relationship between big money and drugs is an odd one. Commercial markets are necessary for developing new products and ensuring that they remain around long enough for scientists to carry out research on them. But the commercial markets are just as likely to kill off' certain products when something more attractive comes along. In the case of aspirin, a potential ‘wonder drug' was around for over 70 years without anybody investigating the way in which it achieved its effects, because they were making more than enough money out of it as it was. If ibuprofen or paracetamol had entered the market just a decade earlier, aspirin might then not be here today. It would be just another forgotten drug that people hadn't bothered to explore.
None of the recent discoveries of aspirin's benefits were made by the big pharmaceutical companies; they were made by scientists working in the public sector. 'The reason for that is very simple and straightforward,' Jeffreys says in his book. 'Drug companies will only pursue research that is going to deliver financial benefits. There's no profit in aspirin any more. It is incredibly inexpensive with tiny profit margins and it has no patent any more, so anyone can produce it.' In fact, there's almost a disincentive for drug companies to further boost the drug, he argues, as it could possibly put them out of business by stopping them from selling their more expensive brands.
So what is the solution to a lack of commercial interest in further exploring the therapeutic benefits of aspirin? More public money going into clinical trials, says Jeffreys. ‘If I were the Department of Health. I would say “this is a very inexpensive drug. There may be a lot of other things we could do with it." We should put a lot more money into trying to find out.'
Jeffreys' book which not only tells the tale of a 'wonder drug' but also explores the nature of innovation and the role of big business, public money and regulation reminds us why such research is so important.

Question: Ancient Egyptian and Greek doctors were aware of
So sánh các cụm ở câu hỏi với bài đọc, ta có:
Ancient Egyptian and Greek doctors = Ancient Egyptian physicians + Greek physician
Giải thích chi tiết
Ta dựa vào thông tin 'Ancient Egyptian and Greek doctors' là có thể nhanh chóng tìm ra thông tin
Thông tin nằm ở 2 câu, nên ta đọc connection với Linearthinking để nắm main idea:
1 Ancient Egyptian physicians used extracts from the willow tree as an analgesic , or pain killer.
2 Greek physician Hippocrates recommended the bark of the willow tree as a remedy for the pains of childbirth and as a fever reducer
=> 1 + 2 : Egyptian + Greek physicians (doctors) - đã biết dùng - chiết xuất từ willow tree - để làm thuốc giảm đau/giảm sốt
=> Phần thông tin còn thiếu ứng với đáp án E - the medical uses of a particular tree
