Today is Sunday, and it stands to reason that Yang Xin needs to go back to school, because classes will be held tomorrow.

However, he did not go back, but asked the principal Liu Yunfang for a day off, and left Tian Jiajia behind, just letting his sister Tian Wenwen go back to school.

The next day, Yang Xin was ready to start teaching Tian Jiajia how to make medicines.

"Old man, this prescription of mine is actually something handed down from our ancestors, and it is very valuable, and now I will teach it to you for free, so I have one condition. Yang Xin Chaotian said.

"What conditions?" asked Old Man Tian.

"This prescription and the method of medicine, I am going to pass it on to Erya, if this medicine is effective for the eldest uncle's illness, I hope that Erya can worship me as a teacher, because only in this way will the rules of the family not be broken. Yang Xin said to the old man.

Without waiting for the old man to speak, Yang Xin continued: "You don't know, our family is actually a big family, and the rules in the family are very big. ”

In order to gain the trust of others, he also fabricated such things as the family.

"That's right, yes, I agreed for Erya. Old Man Tian hurriedly nodded in agreement.

"Classmate Tian Jiajia, what do you say, do you agree?" Yang Xin looked at Tian Jiajia.

"I, I promise. Tian Jiajia nodded.

In her heart, as long as she can treat her grandmother, she is willing to do anything.

"Okay, let's get started. ”

Yang Xin nodded, then took a few medicines to Old Man Tian and said: "Old man, these medicines are medicinal materials that need to be decocted, you can use a frying pan to pour water and decoction, pay attention, you should fry the same, don't fry together." ”

Decoction of medicine, this is the easiest, just add water and boil it.

In addition to decoction, there are many other methods of medicine in Chinese medicine.

Not all Chinese medicines are suitable for decoction, and some herbs will lose their efficacy after decoction at high temperatures, so other methods are needed at this time.

Traditional Chinese medicine extracts medicinal materials, mainly by decoction, impregnation, soaking, modified gelatin, reflux, solvent extraction, steam distillation and sublimation.

The extraction of modern Chinese medicine is centrifugal method, plate and frame filtration method, clarifying agent method, alcohol precipitation method, resin adsorption method, etc.

The prescription for the treatment of rheumatoid arthritis that Yang Xin redeemed from the system mall, several of which require special preparation methods to retain their efficacy.

Moreover, there are several medicinal materials in which some ingredients are very toxic, and it is necessary to use chemical methods to remove the toxicity and retain the medicinal properties in them.

If the toxicity cannot be removed by chemical methods, other medicinal materials should be used to neutralize the toxicity.

For these medicinal materials, the preparation process is a bit complicated, and it is impossible for Old Man Tian to learn it, so he can only let Tian Jiajia learn it.

"When dealing with this medicinal material, we must treat it together with this medicinal material, some of the ingredients in this medicinal material can neutralize the toxicity in this medicinal material, the ratio is about one to five, but we can add more, anyway, we can only do more, not less. ”

"You must remember this, otherwise if this herb is not handled properly, after your grandmother eats it, it will have toxic side effects, and if it is serious, it will be life-threatening, you know?"

"Got it. Hearing Yang Xin's explanation, Tian Jiajia nodded solemnly and said that she understood.

Yang Xin believed what she said, a super genius with a memory of more than ninety years, it was impossible not to remember this thing.

"Come on, you do it again, and I'll see how well you learn. Yang Xin gave up his position and asked Tian Jiajia to try to do it again.

"Good. ”

Tian Jiajia was not timid, nodded and stood in the position that Yang Xin gave up.

Tian Jiajia has a very strong memory, and with Yang Xin, a teacher on the side, to guide her, she soon concocted a medicinal herb according to Yang Xinjiao's method.

However, Yang Xin still didn't dare to be careless, and told her to follow the specifications, and he also explained in detail why she did this.

He was afraid that when he was away, Tian Jiajia did not remove the toxicity when she dispensed medicine to her grandmother, and if she didn't get it right, there would be a problem.

Rheumatoid arthritis is a disease that cannot be cured in the world, and if you want to cure such a disease, how can you do it without special medicinal materials.

And these special medicinal materials are very toxic, and if they are not handled well, they may kill people.

If it were other doctors, it is estimated that they would not dare to prescribe such a prescription, because if they don't do well, they will suffer lawsuits.

For example, Master Li Ke, who is known as the ICU of traditional Chinese medicine, created his own "Exceptional Heart Saving Soup", which rescued many heart failure patients who were notified of death by Western medicine.

After Li Lao died, his apprentices did not dare to prescribe this prescription casually like Li Lao, and even if they did, they did not dare to use fierce medicine like Li Lao, which can explain the problem.

Yang Xin wanted to treat Tian Jiajiatian's grandmother's rheumatoid arthritis, but there was almost no other way than to take strong medicine.

However, even if the medicine works well, there is still no way to recover Grandma Tian's deformed joints, and Yang Xin can only make the rest of her life less painful.

If you want to treat the joint deformity caused by rheumatoid arthritis, you still need surgery, but looking at Grandma Tian's age, it is estimated that even if she has surgery, she can only restore part of the joint function.

However, this is not a problem for Yang Xin to consider, what he is thinking about now is to let Grandma Tian restore the normal function of the immune system, no longer let the condition worsen, and no longer be so painful, it is impossible to be completely cured.

The most important thing is that by treating Grandma Tian's illness, Tian Jiajia will be willing to apprentice, which is the most important thing.

As long as Grandma Tian can be cured, I believe that Tian Jiajia will not reject the apprentice so much, right? After the apprenticeship, he will get the reward, and then teach her medical knowledge, at that time, it doesn't matter whether she is willing to study or not.

It took a day, almost from morning to evening, before Yang Xin concocted all the medicinal materials.

After concocting the medicinal materials, the next step was to dispense the medicines, and he was busy until more than ten o'clock in the evening, and Yang Xin dispensed all the medicines.

Eventually, these pills became finger-sized pills.

The whole pharmaceutical process is very cumbersome and troublesome, and it is impossible for beginners to remember all the pharmaceutical process, but fortunately, Yang Xin recorded it with his mobile phone in this process, and there will be no mistakes in letting Tian Jiajia refer to the video in the future.

"Auntie, the medicine is ready, you can try it. Yang Xin took the pill to Grandma Tian and said.

"Thank you!" Hearing Yang Xin's words, Grandma Tian hurriedly thanked her.

Regardless of whether Yang Xin's medicine has an effect or not, they can see Yang Xin's sincerity and are very grateful.

Grandma Tian couldn't move her hands, so she asked Old Man Tian to feed her medicine.

"This medicine is three meals a day, one pill at a time, it's so late today, you can take this pill, and the rest will be taken tomorrow. ”

Yang Xin Chaotian said: "These medicines can be eaten for a month, if they are effective, let's do them again next month, it is estimated that it will be about the same for three or five months, but this medicine can not be put for a long time, I will use candles to make some wax pills out and seal and preserve them, just crush the wax pills when you eat them." ”
