In ancient times, the premature mortality rate of children was very high, and colds were common, right? This minor disease had a very high fatality rate in ancient times. It is mainly a high fever caused by a cold, and children with weak constitutions can hang up directly. Not to mention children, even adults have a high fatality rate of cold and fever. For example, Juan III, who was rescued by Marin, almost died because of it.

In fact, in his previous life, Marin also often had a cold and fever when he was a child, and his physique was weak. Fortunately, after the 90s, there was no shortage of medicines in the countryside, and when you went to the hospital, there were always antibiotics for you. I remember that at that time, when Marin went to see a doctor, after the doctor took his temperature, he would say, "Let's get X-mycin", and then he entered the terrifying injection link...... Regardless of the side effects of antibiotics, Marlin has been alive since he was a child...... And it is precisely because of his frailty and illness when he was a child, coupled with the popularity of martial arts in the 90s, that Ma Lin often exercised......

But in ancient times, there were no antibiotics used, so children could easily die. Because of this, there is a habit of giving cheap names to children in rural areas, such as two dogs, dogs, and other leftovers. Otherwise, I'm afraid that I won't be able to raise it well.

This is the situation in ancient China, anyway, there are still many Tulang Zhongzhong with uneven medical skills in Huaxia, and there are many children who can be saved.

And in ancient Europe, it was very miserable. Because before the development of modern medicine, European doctors mainly relied on bloodletting and opium tinctures. Of course, there is also the need to ask the priest for "holy water" to drink, or to exorcise evil spirits. In short, until the early 19th century, the level of medical care in Europe was very scary. The dignified King George III of the British Empire, after suffering from a mental illness similar to Alzheimer's in his later years, was actually tied to a chair by quacks and beaten with a stick......

Such poor medical care makes it even more difficult for children in Europe to survive. Even if it is a royal family, it is normal for several princes to die.

Moreover, at that time, people who caught a cold and had a cough or something were also classified as "lung disease", and then died of various diseases......

……

In addition, dysentery, also known as diarrhea, is also a disease with a high mortality rate in ancient times. Especially in ancient Europe, more people died of diarrhea.

Why? Because Europeans don't have the habit of drinking hot water......

Europeans, both ancient and modern, are not accustomed to drinking hot water. In modern times, there is still pure water to drink, but in ancient times, only raw water could be drunk. Then, it was also common for Lasila to die. Among them, the mortality rate of diarrhea in children is particularly high.

In modern times, colds and diarrhea can be solved by going to the pharmacy and buying some cold medicine and diarrhea medicine. Even, cold medicine and diarrhea medicine are common items in ordinary families.

However, in ancient times, especially in ancient Europe, even kings did not have this kind of treatment......

Diarrhea is a little better, at least, opium tincture, which was regarded as a miracle medicine by ancient Europeans, does have the effect of curing dysentery. However, this thing is produced in the Middle East, which is an "imported medicine", which is expensive, and only the aristocracy can afford it. Therefore, diarrhea is a disease that generally kills civilians, especially children among civilians.

It's just that dysentery and diarrhea are actually related to dietary hygiene. Marlin's two sons, Caesar and Robert, never drank raw water or ate any spoiled food, but they didn't have much stomach diarrhea. Moreover, there are also two doctors who are at the level of miracle doctors in Europe, Mozhigen and Battle, who are in the palace.

It's just that Marlin can't promote the habit of drinking hot water. Because, in this era, there is no kettle, and no kettle can be made. If you want to drink hot water, there is actually only one way - to promote the use of honeycomb coal stoves.

Because, even if the honeycomb coal stove is blocked, there is a kettle on it to boil water. Even if there is no firepower, it is not difficult for the spark to heat up whoever is in the pot. As long as there is a honeycomb coal stove, there will be no shortage of hot water at home.

However, in order not to provoke John II, Duke of Cleaver, who had just sold the Ruhr area to his recent ally, Marin did not rush to introduce the honeycomb coal stove. Otherwise, allies will also turn their faces against each other. But in two or three years, the honeycomb coal stove will definitely be launched. After all, it's too convenient. In the absence of piped gas, the honeycomb coal stove is an artifact for urban dwellers to cook.

……

In other words, in ancient times, the two most important diseases that caused children to die were actually colds, fevers, and dysentery, which are common in modern times...... As for the other, more serious diseases, because they rarely occur, they do not have a high mortality rate compared to these two diseases......

Moreover, Marin now has a simple means of treating colds in his hands - brown sugar ginger water, and sweating under the quilt......

As for the fever, there is also a way - rubbing alcohol all over the body to dissipate heat......

It just so happens that now the output of the second pot head in Beihai is very large. And as a by-product of the head and tail of the pot, medical alcohol, is also produced in large quantities. In this way, there is a way to treat fever.

Today, Morrigan and Battle have cultivated hundreds of qualified disciples, scattered throughout the North Sea Kingdom and the colonies. They also learned how to use brown sugar, ginger water, and rubbing alcohol to sweat. Moreover, ginger and brown sugar are now produced in large quantities in Grenada and Cuba, and the cost is not expensive. As for alcohol, that's even less to say.

As for the colds that often occur in children, in fact, Ma Lin, a person with half-baked medical skills, also knows two miracle medicines, Bupleurum and Huoxiang Zhengqi Water. Because, in his previous life, he often had a cold and fever when he was a child, and he took these medicines many times. Especially Huoxiang Zhengqi water...... Even after crossing over, Marin still remembers the bitter taste...... Even, Marin still clearly remembers the recipe of Huoxiang Zhengqi Water......

However, it didn't help. Because, those are all traditional Chinese medicines, mainly produced in China. This is also the reason why Ma Lin is in a hurry to establish contact with the Ming Dynasty - he wants to get those Chinese medicines!

Not to mention the efficacy of Bupleurum and Huoxiang Zhengqi Water, the main drug of Yunnan Baiyao, Panax notoginseng, is also the target of Marin's coveting. Because, during the war years, the demand for special drugs for bruises was too great. Moreover, Marin still remembers the recipe of Yunnan Baiyao.

It's ridiculous to say that the formula of Baiyao still came from Lao Mei. Because, although Baiyao is kept secret in China, in order to obtain the right to sell in Laomei, the formula has to be disclosed on the instructions. This incident caused an uproar at the time, and Marin naturally paid attention to it, so he wrote down the recipe for the white medicine. If you had traveled to ancient China, you would have made money from this hand a long time ago. But now, because it is still in Europe, there are no Chinese herbal medicines such as Panax notoginseng, Sanyu grass, white ox gall, Huai Yam, etc., and Ma Lin can only stare dryly.

In addition to the dispensing of Bupleurum and Huoxiang Zhengqi Shui, as well as the dispensing of Yunnan Baiyao, Ma Lin is also particularly interested in another Chinese medicine. That's it......

Berberine can be extracted, and berberine is a special medicine for the treatment of dysentery and diarrhea. In later generations, Marin would eat berberine tablets when he had diarrhea.

Moreover, the extraction of berberine is very simple - there are mainly sulfuric acid methods, lime water methods, and ethanol methods......

Famarin sulfate did not dare to try it because it was not well controlled. Moreover, Marlin also lacks sulfuric acid in his hands. The lime water method and the ethanol method are very convenient for Marlin. Ethanol, that is, alcohol, marindo is. However, alcohol is quite expensive now, and it is still economical to use the lime water method, and the method is simple - as long as the coptis powder and quicklime are added to the water and stirred, and then salt is added to salt precipitation, berberine can be obtained......

Berberine extraction method is simple, has special effects on the treatment of dysentery, and also has a great effect on Mycobacterium tuberculosis, pneumococcus, typhoid bacillus and diphtheria bacillus. Pneumonia, typhoid fever and pediatric diphtheria were the most important incurable diseases in ancient times, and they were also common diseases.

And, more importantly, berberine has relatively few side effects. Unlike penicillin, which is a domineering drug, the side effects are great.

In addition, it should be noted that many people mistakenly believe that penicillin is easy to prepare. There is nothing wrong with this, because as long as Penicillium is born, penicillin can be extracted.

However, not all penicillin can be used as a drug. Medical scientists selected many penicillin samples and tested them many times before they came up with penicillin that was suitable as a drug. If you use unproven penicillin casually, it may not cure the disease, but directly kill the patient......

Therefore, in the absence of chemical talents under his hands, Marlin has no way to engage in penicillin for the time being. Because, the selection of penicillin strains is a long process. Marin is unfamiliar, but he doesn't have time. After all, he was still the head of a vassal state, and he didn't have time to observe and test penicillin all day long. Therefore, this matter has to wait for the training of chemical talents before acting.

However, berberine extraction is too simple, the effect is so good, and the side effects are still small, there is no reason why Marlin is not high. What he wants to do is to introduce a large number of Coptis chinensis seeds from Daming, and then plant them on a large scale in North America, where the climate is very similar to that of China, and then extract and use them......

Similarly, important traditional Chinese medicines such as Bupleurum chinensis, Huoxiang, and Panax notoginseng are also planned to be introduced in large quantities and planted in North America. At that time, there will be no shortage of these medicines, which can be used by ordinary people in Beihai countries, reducing the mortality rate of diseases and the mortality rate of children.

It is precisely because Huaxia has too many things that Marlin needs, including these life-saving medicines, that Marin is so keen on the Great Voyage. Even, after Amerigo finished exploring the Daming Pacific route this time, he planned to go to Daming in person, introduce enough Chinese medicine seeds, and get some Chinese medicine to improve the medical level of Beihai Country......
