With a concentration of 70% to 75% alcohol, it is possible to disinfect all kinds of traumatic wounds. Pen & Fun & Pavilion www.biquge.info However, Dai Yan has a better idea for alcohol, that is, to make iodine wine!

Iodine wine is actually an alcohol solution containing iodine, and its sterilization and disinfection ability is stronger than that of medical alcohol, and it can even play a certain role in tetanus! If such a thing can appear, then most of the external injuries left on the battlefield, as long as they are dealt with in time, can basically save the lives of soldiers!

And the acquisition of iodine, in today's Taoqiu has a strong maritime industry, is actually not a particularly difficult matter.

After all, there is kelp in northern China and even along the coast of Japan, and kelp contains a lot of iodine.

To extract iodine, the kelp must first be ground into flakes and ashed at high temperatures. The ashed kelp has a large amount of iodine. The ashed kelp is boiled and filtered many times to obtain an aqueous solution containing iodine. This aqueous solution is actually a hydroiodic acid solution produced by the reversible reaction of iodine and water.

In later generations, the industrial iodine production method was to replace the iodine by adding chlorine gas into the hydroiodic acid solution, and then extracting the iodine with carbon tetrachloride. Today, Dai Yan can neither get chlorine nor carbon tetrachloride, all he can get is sulfuric acid. In the iron ore of Xiangyi, part of the green alum, that is, the hydrate of ferrous sulfate, can be obtained. Calcining the green alum can obtain the concentrated sulfuric acid called "green alum oil" by the ancients, which is the oldest method of preparing sulfuric acid.

If you want to replace iodine from the aqueous solution, you only need to add sulfuric acid, and then introduce air from it, and in such an environment, iodine can be completely replaced by oxygen. The final solution is completely evaporated, and the iodine in the final aqueous solution will be completely sublimated, so that iodine can be obtained.

Of course, Dai Yan's method can only produce a small amount of iodine. However, in today's era, there are some disinfectants that can treat tetanus, which are actually a big killer!

In the case of concentrated sulfuric acid, Dai Yan can also use concentrated sulfuric acid to continue to react with high-concentration alcohol, so that the alcohol can continue to dehydrate, so that the perfect anesthetic - ether can be obtained. Ether is one of the earliest anesthetics for modern medicine to perform surgery, with it, and disinfectants such as medical alcohol and iodine wine, the obstacles to surgical operations are completely removed!

With the ability to perform surgery, Tao Qiu was able to treat many diseases. At least to treat appendicitis, this kind of stunt mastered by Hua Tuo in later generations, Tao Qiu is capable of doing it. The success of the surgery also made caesarean section possible, which greatly reduced the infant mortality rate in Taoqiu! If surgery continues to develop, maybe it won't be until Hua Tuo's time, and the craniotomy will be successful!

Of course, the premise of all this is based on an experienced surgeon!

Dai Yan's training for doctors was carried out among the disciples of the peasant family, because the peasant family claimed to be a disciple of Shennong and had certain medical skills. And they have medical ethics and believe in science, at least not to use mysticism to cure diseases like the wizards of this era.

As for the system used in medical treatment, Dai Yan did not adopt the methods of traditional Chinese medicine. There have been many debates about Chinese medicine in later generations, although Chinese medicine has many advantages, but in Dai Yan's view, Chinese medicine is essentially an accumulation of experience. With thousands of years of history in China, it has naturally accumulated a lot of useful treatment experience, but in today's era, there are very few medical books in the world, and the only medical faction that can be called a system is Bian Que. And Bian Que is in the same vein and the dragon is not the end, where can Dai Yan find so much experience to develop and study Chinese medicine?

Therefore, he directly used modern medical theories. As for the structure of the human body, he could only vaguely tell the disciples of the peasant family through the memories of later generations. The role of various systems of the human body and the functions of various organs are generally clear to Dai Yan. Naturally, he doesn't think of the heart as an organ of human thought, nor does he really think that one drop of sperm is equivalent to ten drops of blood.

After explaining the eight major systems in the human body and the functions of the internal organs of each system, Dai Yan also explained the role of each tissue and the most basic unit that makes up the human body - the cell. At a time when Taoqiu had not yet invented the microscope, Dai Yan could not make the peasant disciples fully believe what he said, but Dai Yan promised that he would give perfect proof in the future. Relying on Dai Yan's previous correctness and good reputation, he then chose some dead people to be autopsied, and finally the peasant disciples believed what he said, and approved of the medical system he proposed, and then abandoned the ancient empirical medical system.

Later, in the battle between the Taoqiu Sailor and the Onozawa Water Bandits, a team of doctors composed of peasant disciples also followed the Sailor to the battlefield, and the wounded soldiers on the battlefield, as well as the enemy bandits, were all rescued by the doctors. In this kind of rescue, Dr. Tao Qiu continued to perform various surgeries, which made their medical level also greatly improved, and soon the chance of being able to cure the external injuries suffered by ordinary people easily increased to more than 90%!

And in the process, some of the special drugs they found are also very important. Among them, the most important medicine is thistle. It can be applied both externally and internally. The thistle is a very good medicinal material for the treatment of traumatic bleeding, or the body's vomiting of blood, blood in urine, etc. For the system of traditional Chinese medicine, Dai Yan can ignore it, but for traditional Chinese medicine that can cure diseases, Dai Yan attaches great importance to it!

The thistle soon became one of the strategic materials of the entire Taoqiu.

After accumulating a wealth of experience in surgery, the doctors formed by the peasant disciples began to turn their attention to the diseases within the human body.

Although the entire Taoqiu has generally controlled the outbreak of various infectious diseases, the occasional sick patient does make Dai Yan embarrassed. Fortunately, these problems have finally been solved through the joint efforts of Dai Yan and Dr. Tao Qiu.

For common typhoid fever, the best treatment is nothing more than the use of antibiotics. Although the proliferation of antibiotics has caused some serious problems in the era of Dai Yan, it is undeniable that the discovery of antibiotics has made outstanding contributions to the prosperity and development of human society.

The best antibiotic is naturally penicillin, but since its discoverer can win the Nobel Prize in Physiology and Medicine, it is naturally not something that Dai Yan can simply control. Its production requires the cultivation of penicillium with petri dishes and culture medium, which involves many complex issues, and Dai Yan asked himself that he could not easily copy penicillin today.

So he came up with another natural universal antibiotic, which is allicin, which is contained in garlic.

However, the era he traveled through was indeed a little unlucky, in this era, China had not yet had large-scale exchanges with the West, and many species had not been introduced to China. Unfortunately, garlic is one of them.

However, as a time-traveler, luck and decay are both present at the same time. When he learned that the Wu tribe on the grassland had a large-scale trade with the West, he had a direct communication with the young master of the Wu tribe, and he gave the Wu Shao Lord a large amount of tea as a deposit, hoping that the Wu Shao Lord could introduce a large number of Western species to China.

There are three species that Dai Yan attaches the most importance to: alfalfa, cotton and opium poppy, but none of these three have been introduced.

Alfalfa is commonly known as clover, it is rich in vitamins and is the best feed for livestock! And it can fix nitrogen, improve the characteristics of the soil, once it can be planted on a large scale, it will greatly improve the level of agricultural cultivation in China! For the Chinese country, whether it is a purely agrarian country like Wei and Song, or a semi-nomadic country like Zhao and Yan, it is a strategic species that can directly enhance the strength of a country!

The role of cotton is even greater, and in today's Taoqiu, among the four resource bottlenecks, the only resource bottleneck that Dai Yan has not solved is fiber! And cotton is the best fiber material, once Taoqiu has cotton, then the emergence of light industry is also possible!

As for the opium poppy, when people in later generations think of this thing, they will naturally think of opium, a drug. In fact, opium poppy can be used as a very good medicine, it is a traditional Chinese medicine antidiarrheal medicine. And the most important use of this kind of thing is actually that it can be used as a very good anti-inflammatory and painkiller. Most of the time, the patient is depressed and unable to tolerate the pain. If there is a good painkiller at this time, it can actually save many lives!

Bayer Pharmaceuticals, one of the most powerful pharmaceutical companies in later generations, used morphine, a plant alkaloid extracted from opium, to react morphine with acetic anhydride in the early years, thus obtaining a drug called morphine diacetate. Because the pain relief effect of this drug is 4 to 8 times that of morphine, it can suppress people's cough and chest pain, and make patients emotionally stable. Because of its powerful effect in the treatment of pain, depression, etc., the Germans gave it the title of "heroine", which translates into Chinese as heroin. With the powerful effect of heroin, Bayer Pharmaceutical has made huge profits, which is also the fundamental drug that Bayer was able to start with.

It can be seen that pain-relieving drugs are actually a very useful tool for human beings!

As for saying that this kind of thing will be used for other purposes in this era, and pull the Chinese country to the point of degeneration like the Qing Dynasty, Dai Yan does not believe it at all. In the 19th century, there were many countries in the world that smoked opium, such as England, where even babies were smoking this thing in the homes of the workers at the bottom, and their middle class, even great writers like Dickens, smoked opium, and did not see Britain really degenerate to the point of my Qing Dynasty. Because the British need to work hard and struggle, the whole country is still creating wealth.

And in my Qing Dynasty, opium smokers are really not what ordinary people can do. Those who can enjoy this "wonderful" are those maggots parasitic on the Chinese civilization, such as bureaucrats at all levels, the officers and soldiers of the Eight Banners Green Battalion, and even the princes and nobles of the Manchu people, who really have the money and leisure to enjoy this thing. This group of people who don't do anything, only know that they opium smoking opium is equivalent to the collective degeneration of the parasites in the entire Chinese civilization, so can the country not fall in a more corrupt posture?

In the first three transactions between Dai Yan and Wu Shaozhu, he did not get the three species he wanted the most, but he also unexpectedly got some things, such as sesame seeds, grapes, cucumbers, broad beans and carrots, these things arrived in Taoqiu, which can be regarded as enriching the dining table of all Taoqiu people.

And not long ago, in his fourth transaction with Wu Shao Lord, his character finally broke out once, and he got garlic, which is the most valuable species that Dai Yan introduced from Wu Shao Lord!

Garlic can not only be used as a condiment, but also enrich the diet of the Taoqiu people. And by mashing fresh garlic, he got the universal antibiotic allicin, under the action of this universal antibiotic, most of the wind chill caused by intestinal bacteria can be completely treated!

Soon after that, the disciples of the peasant family found some clay ores in the Jiangnan area that can treat intestinal typhoid fever, and after this stone is ground into powder and turned into a scattered form, it can perfectly solve some intestinal typhoid fever, and when combined with allicin, it is simply unfavorable!

After Dai Yan saw this ore powder, he initially guessed that it might be the famous montmorillonite powder in later generations. He asked the doctors to study it carefully and was relieved to confirm its efficacy.

The emergence of two powerful drugs has given the doctors trained by Dai Yan a strong credibility. After all, in the face of life-saving grace, people are the easiest to blindly follow and believe something.

The problem of typhoid fever was solved, the cooperation between Taoqiu and the nobles of the East China Sea, and the expansion overseas, the frequent occurrence of malaria also became one of the most serious problems in Taoqiu.

In a developed city like Taoqiu, Dai Yan could certainly suppress the occurrence of malaria by clearing stagnant water and eliminating the breeding environment for mosquitoes. However, in the difficult environment overseas, such problems are not easy to solve. The people of Taoqiu, as well as some of the nobles of the East China Sea, had contracted malaria and died, making the cost of expansion prohibitive, and Dai Yan had to help solve the problem.

Traditionally, the drug used to treat malaria is naturally quinine, also known as cinchona. However, this thing, like rubber, is produced in the South American continent, and it is not within Dai Yan's reach. The only way he could think of was the artemisinin that he had prepared by the scientists of the Celestial Empire and won the Nobel Prize in Medicine before he crossed over.

Artemisinin is extracted from Artemisia annua, and Dai Yan learned in later generations that the inspiration for scientists in the Celestial Empire to extract artemisinin came from the ancient prescription "Elbow Reserve Emergency Prescription". Dai Yan carefully studied this prescription, and finally boiled it with a small amount of artemisia annua, added a large amount of water, and took the juice orally, and finally obtained artemisinin, which can treat malaria.

In this way, Artemisia annua leaves have become an indispensable medicine for the land of the East China Sea and the navigation industry.
