"Fang uses four coins of angelica, three coins of cinnamon and white peony ginseng, two coins of licorice in Tongcao, two large pieces of aconite, four coins of mountain corn keel oysters, three coins of salvia, eight jujubes, eight liters of water, three liters of boiling, and three liters of water. Take one liter of warmth, three times a day" Xu Xuan quickly opened the prescription and handed it to Zhu Danxi on the side.

"Senior brother, the aconite in the square, please weigh it separately, let me concoct it a little to weaken its toxicity."

Zhu Danxi glanced at this recipe, nodded, and weighed the drug first, Xu Xuan took the medicine, and went straight to the back hall, the ancients in this era, concocted highly toxic medicinal materials such as aconite, and mainly used the method of smoking and roasting by the fire, the drug is often burned, not to mention the reduction of the curative effect, even the poison in this aconite aconite, it is not weakened at all, so once aconite is used in ancient times, the amount of medicine is slightly larger, and it is easy to be poisoned, so quite a lot of ancient doctors, The application of aconite is very cautious.

What Xu Xuan has to do is to use modern methods to reduce the toxicity of aconite, and he should be grateful to Xu Xuan's College of Traditional Chinese Medicine, which does not strictly regulate the curriculum of students like other medical schools, so Xu Xuan was fortunate to listen to a semester of Chinese medicine processing in the Department of Traditional Chinese Medicine and Pharmacy in his sophomore year, so he still has a bottom in his heart about how to concoct it.

Modern medicine, for the composition of traditional Chinese medicine and toxicity research, has been very perfect, so it can also make targeted processing methods for the drug.

Xu Xuan carefully looked at the aconite in his hand, which was specially concocted with Qingyutang's secret recipe, that is, soaked in mung bean licorice water, and then simmered over low heat, so that it was used, relying on licorice and mung bean soup, which has the property of detoxification, so that the aconite can absorb the medicinal liquid, so that the toxicity of aconite will naturally weaken, however, Rao is so, aconite poisoning is not uncommon, but compared with other medicines, the probability of poisoning is already very low.

However, Xu Xuan is still not satisfied with this, although Cheng Fang seems to be in good health, but he has been made a mess by a doctor's wrong medication, and he can't stand the irritability of aconite, so he must ease the medicinal properties. In other words, the content of various alkaloids in aconite is too high, which has too much impact on the human heart, and if it is not rectified, it will lead to arrhythmia and sudden death.

After a while, Xu Xuan came out with the processed aconite.

"Mr. Cheng, this medicine is quite hot, and it is related to the cold and evil in the body, and I am afraid that there are other symptoms, so the old man still uses medicine in our Qingyu Hall, let me wait for a while to observe." Xu Xuan said to Cheng Fang.

"Still waiting here?" Cheng Fang frowned slightly.

"Master Cheng, the case is fine. Some small things, Wang Yuhou and I will deal with them, adults don't have to worry, let's go over here," He Zhutou on the side stood up and said to Cheng Fang.

"In this way, it will trouble He Zhutou and Wang Yuhou." Cheng Fang thanked him.

"Then I'll go to decoction, old gentleman, wait a while" Xu Xuan took the medicinal materials in Zhu Danxi's hand and walked towards the decoction place in the back hall, Zhu Danxi glanced at Xu Xuan, chased after him quickly, and when he entered the back hall, he asked softly, "Senior brother, are you sure?" ”

Xu Xuan smiled and glanced back outside, and found that no one followed, but he shook his head, "The doctor treats the disease, and he is sure of it, but he does his best."

Hearing Xu Xuan's words, Zhu Danxi's face was even more worried: "Which junior brother, you won't persuade Bachelor Cheng?" If such a character has an accident in our Qingyu Hall, you and I can't escape, even the master, I am afraid that we will also be implicated, and the junior brother has not heard it, Master Cheng's illness, Li Yuanzheng of the Beijing Division, dare not use such a prescription from the master, how can you ...... it?"

Xu Xuan shook his head and said, "If it is someone else, I will not pay attention to it, don't say that the ordinary doctor of Jingshi is our doctor in Qiantang, as long as the medical skills are passable, they know how to treat this real heartache, how can the hospital of Jingshi not know?" I'm afraid that this court is not ignorant, but it can't be treated like this! ”

Zhu Danxi was shocked, "If you say this like your junior brother, isn't there someone who wants to harm Master Cheng?" ”

Xu Xuan's face was heavy, "I'm afraid this person is not trying to harm Lord Cheng, his purpose is to make Lord Cheng's body unharmed for the time being, and after doing something extremely critical, it will be okay if something happens, and this person is afraid that he is an extremely powerful figure,"

Zhu Danxi's face changed greatly, "Senior brother, let's say this, why can't we cure it, it's trouble, won't it cause even more trouble if we cure it?" ”

Xu Xuan nodded, but he didn't want to say it anymore, and sighed in his heart, but it was the old man who helped him at the beginning, and he couldn't bear to watch him die like this, but he didn't think that he would be involved in such a whirlpool, which was really not what he wanted to see.

"You don't need to worry, if there is something, you don't have to worry about it, the old man will write to the court in a while, please rest assured" Suddenly, Cheng Fang's voice sounded outside the door, Xu Xuan and Zhu Danxi hurriedly looked back, only to see Cheng Fang standing at the door of this corridor, looking at them and saying.

Zhu Danxi still said, "Old man, my junior brother is young, although he is talented and intelligent, and he has a lot of fate for the way of medicine, but the time to study medicine with the master is still short, whether the old man takes medicine, please think twice"

Cheng Fang shook his head, "Your junior brother is a profound doctor, but the old man is a little curious about Master Ling, what kind of doctor can teach such a student, he is young, and he has already achieved such achievements." Since Xu Xuan has already diagnosed my illness, as a patient, the old man naturally has to listen to the doctor's words and take the medicine on time. ”

After speaking, Cheng Fang looked at Xu Xuan, "Xu Xiaoyou, please decoction medicine"

Xu Xuan sighed, turned around and entered the kitchen, and after a while, Xu Xuan had already fried the medicine and put it in front of Cheng Fang, and then stepped aside, looking at the smoking decoction, Cheng Fang couldn't help but get nervous.

"As my senior brother just said, old man, you still have to think about it before taking the medicine, this medicine is quite hot, adults take it, I'm afraid there will be a heartache emergency, adults have to think about it" Xu Xuan looked at Cheng Fang and said solemnly.

"Haha" Cheng Fang suddenly laughed, "It made Xu Xiaoyou laugh, the old man has lived in vain for fifty years, and he was scared when he looked forward to it,"

With that, he picked up the medicine bowl and drank it in one gulp.

"Senior brother, please prepare the master's silver needle, and also take the musk borneol, as well as the medicinal powder of the Chuanxiong salvia that I cooked last time!" Xu Xuan looked at Cheng Fang with a solemn face, and said to Zhu Danxi without looking back.

What Xu Xuan wants to prepare is that when he first arrived at the pharmacy, he had nothing to do, and after the thick paste from the decoction of Chuanxiong salvia, he slowly dried it with a simmer, and what was made was the crude extract of Chuanxiong salvia, which was mixed with musk borneol, and became the most common quick-acting heart-saving pill and salvia dripping pill in modern society. It's just that the extraction method is poor, and the effect is certainly not as good as that of modern medicines. But in this day and age, it's better than nothing.
