Qin Feng carefully looked at Hua Tuo's prescription. Pen, fun, pavilion www. biquge。 info

Honeysuckle, Forsythia, large green leaves, indigo root, indigo, horsetail, purple lily, dandelion, andrographis and so on.

Hundreds of antibacterial Chinese medicines are combined into more than 100 prescriptions.

Qin Feng knows that the plague is caused by Yersinia pestis, and bacilli are bacteria, and it is absolutely correct to use antibacterial drugs.

Among these prescriptions, there are those that are specially taken internally, those that are specially applied externally, and those that are taken internally and applied externally. These Chinese herbs are all excellent antibacterial effects in traditional Chinese medicine, and with the matching of Huatuo, the antibacterial effect will be even better.

How could it not be effective?

"Is the medicine enough?" Qin Feng asked.

Hua Tuo hurriedly said: "Lord, the medicinal power has been put to the maximum, for example, this combination of honeysuckle plus plate blue root plus general and skullcap purslane, you can't increase the amount anymore, and if you boil it out and drink it, something will happen." It is a medicine that is three parts poisonous, and if the medicine is too powerful, it is not medicine, it is poison. ”

Qin Feng nodded, his heart suddenly moved, and said, "The medicinal power I said also has another explanation. You see that it is also a bowl of medicine, if it is purified, the effect is better, so that it can release the medicinal power at the fastest speed in a short time, will it have additional effects? ”

This absolutely makes sense in theory, with the same medicinal power, it is digested and absorbed in the stomach, and it is naturally more direct than injection.

Hua Tuo was stunned for a moment, and then he was sad after a moment of joy, and said: "Lord, I can understand what you said, it makes sense, but how to condense and refine it?" ”

yes, how to refine it? Nowadays, taking medicine is to boil medicine into potions, and some prescriptions need to be eaten directly to make large pills or powders. There's really nothing else to do but that. Moreover, today's powder is not the concentrated powder of later generations, but the herbs are chopped up, and it has nothing to do with concentration and refinement.

Qin Feng said: "Yuanhua, since ancient times, traditional Chinese medicine has used water as a solvent, and decoction is the most commonly used method. This method is simple and effective, and can boil out most of the active ingredients in the herbs, and in addition to being used as a decoction, it can also be further processed to make pills and powders. ”

Hua Tuo kept nodding, "What the lord said is very true. ”

"But there are too many impurities in this method, which affects the exertion of medicinal power."

"Yes."

Qin Feng actually pondered by himself as he spoke. With today's scientific and technological strength, too many concentration and refining methods in later generations cannot be used, mainly because there is no equipment, such as vacuum devices and ultrasonic oscillation devices.

But it was precisely because there were too many that it was useless, but the options were compressed, which made Qin Feng think of a possibility.

Qin Feng was really excited, and said, "Yuanhua, I have a way, maybe I can purify it again." I tell you, you go and try. ”

Hua Tuo was even more excited, he felt that this time he had come to the right place, and the lord had too many wonderful ideas. But there are too many things to do, and if I don't come, it will be difficult for my lord's energy to concentrate on these aspects. "Tell me, my lord." Hua Tuo immediately took out a small notebook.

"This is actually very simple, it is distillation, and steaming is steaming is steaming." Qin Feng said.

Distillation is a commonly used method for separating and purifying liquid mixtures. However, distillation appeared with winemaking, and the Eastern Han Dynasty did not distill wine, and there was no such concept as distillation at all.

"Distill! How do you distill it? "Although Hua Tuo has feelings about 'steaming', he is still full of question marks.

Qin Feng's thoughts became clearer and clearer, and he said: "The effect of the herb dissolves into the water, and it becomes a bowl of medicine. But in this bowl of medicine, there are still many impurities that the patient drank together. We have to be thoughtful, and in the face of unknown diseases, everything must be considered. Perhaps it is because of these impurities that affect the exertion of medicinal power. ”

Hua Tuo nodded again and again.

Qin Feng said again: "Therefore, we use distillation, that is, to refine the decoction that has been boiled again. Boil completely over fire. ”

"Ahh Lord, the medicine is gone! Hua Tuo said hurriedly.

Qin Feng taught: "You can add a layer of cover to the pot, and these medicinal water vapors will adhere to the lid to form distilled water rich in medicinal power. These distilled potions can be said to have been completely purified, and the medicinal power of these waters is much better than that boiled out of the pot. ”

"Water vapor becomes morning dew, and medicine gas also becomes dew?" Hua Tuo exclaimed.

"The children can be taught." Qin Feng nodded.

Hua Tuo touched his white beard, and his mind was immediately lit up, but he was in trouble, "How to collect it?" ”

Qin Feng hated that iron could not become steel, "If there is more water vapor, it will liquefy and flow down the lid, you can make a container on the inner wall to collect it." After boiling the medicine, as soon as the lid was lifted, there was a lot of colorless liquid, which was distilled water rich in medicinal power. It's just that now we're collecting this. Well~, it is also necessary to develop a little better equipment to prevent the loss of water vapor. ”

Hua Tuo's face turned red, "It turns out that the water on the lid is rich in medicinal powers, and my subordinates used to think it was water." ”

Qin Feng taught: "A bowl of medicine is boiled until it is dry, where does the medicine go?" There must be a place to go, in fact, it is to become water vapor and disperse into the heavens and the earth. ”

After some discussion, Qin Feng felt that this method could be successful, at least it strengthened the efficacy of the medicine. He instructed Hua Tuo to hurry back to study this kind of purification, and give it to the patient again to see if it can produce results.

Hua Tuo didn't stop, and rushed out of the Prime Minister's Mansion.

Three days later, Hua Tuo's bitter gourd face came to Qin Feng again and said, "Lord, the equipment can't be made...... ”

Water refining technology requires targeted equipment, although it is not as complex as TV refrigerators, but for ancient people, the difficulty of tackling key problems is still unimaginable.

Although Qin Feng came from later generations, he was also a big head for a while, but he quickly mobilized his great inventor Ma Jun and the master of the mechanism Huang Chengyan who made parts to arrive.

Fortunately, Qin Feng has Ma Jun, the only great inventor in the Eastern Han Dynasty, and Huang Chengyan, the only master of the mechanism. Finally, such a device was manufactured.

Time waits for no one, and the gears never stop.

The four dead soldiers under Dong Cheng crossed the Yellow River.

These four people quickly sent the blood edict to Cao Cao and others, and then rushed to other directions. But the four dead men who crawled out of the pile of dead people soon fell ill and died on the way. died on the road to Yongliang, Shuzhong, Jingzhou, and Jiangdong. This led to Liu Zhang, Liu Biao, Sun Ce, Ma Teng and others not receiving the blood edict of Emperor Xian of the Han Dynasty.

Their bodies were lying on the side of the road, in the woods, or floating on the river. And some people found that they were all walking around, and they didn't dare to go close to see it at all. When the local government heard the news, mosquitoes and flies bitten the corpses, rats and other scavengers devoured the corpses, and the summer heat caused the corpses to rot and blur. And because of the chaos in the world, there are too many cases of displaced people dying and starving to death, and everything is hastily buried everywhere.

Cao Cao, Yuan Shao, Liu Bei, Lu Bu, and Yuan Shu received the blood edict of Emperor Xian of the Han Dynasty. They scoffed at Emperor Xian of the Han Dynasty's order to call on them to take the opportunity to attack the Northland, they didn't care whether they could save the Han family or not, no one was stupid, and attacking the epidemic area was to find death.

In line with the spirit that if they don't die, they won't die, and they won't attack Qin Feng.

However, since they were able to hit Qin Feng's prestige, they were naturally willing to do it. With their encouragement, the rumors that had been circulating in the Northland began to prevail in the world. It has spread so widely that it has become a trend of falsification and truth.

The people were suspicious at first, but as the rumors spread widely, the princes added fuel to the fire, and the fake has become true. The people from all over the country who were interested in Qin Feng were hit hard, and they exclaimed, "Could it be that the great savior is really a curse for being unvirtuous?" ”

Qin Feng's reputation was hit hard because of this. (To be continued.) )
