Zuo Shaoyang's heart moved, Zuo Gui's father did not allow them to publicize this matter outside, saying that it was not allowed to use the method of squeezing others to elevate themselves. Fennel listened to her father very much, she definitely didn't say it, her mother wouldn't say it, and of course she didn't say it, so who spread the word about it? However, there were indeed many people watching at the door at that time, presumably those people said it. This is good, and it is very helpful to improve the reputation of Guizhitang. Hearing him praise himself, he hurriedly smiled and said, "Thank you for your old praise." It's just that this recipe is indeed our Guizhitang's. I don't have the skills to create my own recipe. ”

"Your father doesn't have the ability, I'm sure of that." The old tea guest didn't believe it at all, and waved his hand: "Okay, don't talk about this, let's talk about the old man's illness, although your prescription is correct, but, alas! I'm afraid it won't work. ”

"Why?" Zuo Shaoyang asked hurriedly.

"I don't know, the prescription I used before was similar to yours, after taking the medicine, I was dizzy, and I vomited after a short time, and I vomited again after eating, which was very uncomfortable. Anyway, the pain hurts, and if you can bear it, you can't die, and you would rather be in pain than suffer that living sin, so it was too uncomfortable to take two doses of medicine, so I didn't take it again. ”

Zuo Shaoyang asked, "Where did you prescribe this prescription?" ”

"Doctor Ni of Huimin Hall, hehe, the entire Hezhou Mansion Pharmacy Medical Hall, count him boss, we Hengchang will only sell medicine and will not look at the disease, the old man will not look for him. The prescription he prescribed is similar to yours, so I am amazed, it seems that your medical skills should not be under Dr. Ni. Hey hey"

"You praise it absurdly, how dare I compare it with the world's famous doctor Dr. Ni."

"Well, not arrogant, not arrogant, good. In fact, the medical skills of this surnamed Ni are not very good, and he is also called a famous doctor in this acre and three points of land in Hezhou. He's nothing. Don't be discouraged, your medical skills are already very good now, work hard, and one day in the future, you will definitely surpass him. ”

"Yes, thank you for your encouragement." Zuo Shaoyang thought to himself that this old tea guest didn't know what to do, he really had something to say, and he was not afraid of offending people. Touching my chin and thinking about it, the patient has intestinal reactions after drinking, and there are many reasons for this, so I will find out clearly. Asked, "After taking the medicine, are there any other symptoms besides dizziness and vomiting?" ”

"Yes, my mouth and tongue are numb, and sometimes my body is numb, and my heart is restless."

Aconitum poisoning symptoms! Zuo Shaoyang understood, and said, "Do you remember the dosage of this recipe you prescribed?" ”

"Remember, the cannon aconite uses three taels."

Generally speaking, Sichuan Wu single oral powder 12 grams, or take decoction within 60 grams are safe, if the use of the correct preparation method of Sichuan Wu, the dosage can be very large, Yunnan famous doctor Wu Peiheng, Chinese medicine Vulcan sent a descendant, because of the good use of aconite, aconite, people sent the nickname "Wu aconite", the amount of aconitum aconite is amazing, often five pieces of eight hundreds of grams of use, but there is no disease poisoning, the effect is significant, so, although aconite, aconite is highly toxic, but as long as the method is concocted, the same can be used in large doses.

In the prescription prescribed by Dr. Ni to this old tea guest, three taels of aconitum are used, two in the Tang Dynasty are similar to two in modern cities, three taels is equal to one hundred and fifty grams, which has obviously exceeded the safe dosage, and whether it will be poisoned depends largely on the processing method, and the processing method determines the degree of weakening of the poisonous surname of aconite. Judging from the numbness and palpitations in the mouth and tongue and even limbs after taking it, the patient has already had a mild toxic reaction. It is likely that it was not concocted.

Zuo Shaoyang said: "Have you ever concocted the old aconitum aconitate?" ”

"Of course I did."

"How do you know?"

"Because the herbs are all concocted by myself."

"You concocted that?" Zuo Shaoyang was surprised.

The fat tea guest next to him smiled: "Boy, are you really blind?" This old boy is our largest medicinal herb merchant in Hezhou, and the old shopkeeper of 'Hengchang Pharmacy'! People give the nickname 'Wish Medicine Cabinet'! ”

Zhu Yaohe stroked his beard and waved his hand a little proudly: "Don't mention these, in the past, they didn't come to my Hengchang to take medicine, but two years ago, the old man picked his son and gave the medicine store to his son, and the old man made tea all day long, and he couldn't meet them, and the two naturally separated." Huh"

When Zuo Shaoyang heard this, he hurriedly got up and bowed: "The little nephew broke his head a few days ago when he was collecting medicine, and I can't remember many things clearly, and if I am rude, please wish the old man Haihan." ”

"Oh?" Zhu looked him up and down in the medicine cabinet: "You took medicine and fell and injured yourself?" ”

"Well," Zuo Shaoyang leaned down, tilted his head, separated his hair with his hands, and showed him the scar on the back of his head, "Oh, this scar is still there." ”

Zhu glanced at the medicine cabinet, stroked his beard and sighed: "Well, the injury is not light." Are you okay now? ”

"Thank you uncle, it's fine."

"That's good. You just asked the old man about the preparation of the medicine, is there a problem with the medicine used by the old man? ”

"It should be,

Zhu Medicine Cabinet said: "Let's continue the conversation just now." The old man began to think that there was a problem with the prescription, and went to Huimin Hall to ask Dr. Ni, he said that the prescription was fine, if it was nausea, it could be taken in small quantities and many times, I followed it, although it was better, but I still felt sick to the stomach, so I simply refused to accept it. Now I hear that the prescription you prescribe is similar to his, which makes me believe that his prescription is indeed fine, and the problem should be the medicine. What do you think is wrong with me? ”

Zuo Shaoyang said: "How did you concoct aconitation? ”

Zhu Medicine Cabinet squinted at him and smiled: "This method of concocting is the secret of various medicine stores, I'm afraid it's inconvenient to say?" ”

Zuo Shaoyang was born in a university class, systematically studied the processing of traditional Chinese medicine, and after graduation, he worked in the pharmacy of the Chinese medicine hospital, engaged in the processing of commonly used medicinal materials, and also knew the processing methods of various commonly used drugs in ancient and modern times. In particular, attention is paid to the processing methods of toxic drugs such as aconitum and Aracea. I have studied the methods recorded in the medical books of the past dynasties, so I remember them clearly.

The poisonous component of aconitum is aconitine, which is easy to be hydrolyzed, so to prepare aconitum aconitum, it must be heated with water for cooking to promote the hydrolysis reaction so that aconitine can decompose and achieve the purpose of detoxification. The results vary greatly depending on the method. Modern processing of aconitum is to soak in water until there is no dry core inside, and then take it out and boil it with water for four to six hours, or steam it for six to eight hours, take out one of the large solid parts and cut it, there is no white heart in it, and the mouth tastes slightly numb.

Before the Tang Dynasty, Chuanwu, Caowu, and Aconite were mainly used to burn with artillery, that is, the medicinal herbs were wrapped in mud and wet flour, and placed in the hot ash by the fire pond to simmer until the medicinal herbs cracked. There are also those where the herbs are wrapped and roasted directly over the fire.

The disadvantages of this method are obvious, although the high temperature can reduce the poison of aconitum medicinal materials, but because the heat is not easy to control, the barbecue time is not easy to grasp, the fire is large for a long time, the medicinal materials are easy to burn, and the low can not achieve the purpose of processing. The results of modern medical research have proved that although the dry heat of this simple barbecue can reduce the poison to a certain extent, it will also reduce the active ingredient of aconitum aconite, and if burned, it may even lead to the loss of medicinal ingredients. The correct way to prepare aconitum herbs is to boil them for a certain period of time or steam them in a cage.

Because the processing method before the early Tang Dynasty is not scientific enough, the quality of the processed medicinal materials is very different, it is difficult to meet the clinical requirements, the same is the amount of aconite, if you encounter the concoction of too much aconite, it will be because of the loss of the medicinal ingredients and the amount of medicine is not enough, can not play the expected medical effect, if the processing is not enough, it will cause the patient to be poisoned, so the ancient doctors of aconite, aconite poisonous medicinal materials, the use is very cautious, rather insufficient than excessive. Although the dosage specified in the "Treatise on Typhoid Fever" is very large, in practice it is far less than this requirement, because the method of preparation is not reassuring.

The dosage of this Dr. Ni was already quite large in the early Tang Dynasty, which shows that his courage is indeed big enough. It's just that if you don't have the guts to heal the sick, sometimes it's not a good thing to be too bold.

Zuo Shaoyang couldn't help but laugh when he heard that the medicine cabinet refused to say how to concoct it, and said, "Uncle Zhu, your line should use the smoking ash cannon method to concoct Sichuan Wu and Caowu, right?" ”

Zhu Medicine Cabinet was taken aback again, and glared: "You know? ”

After the middle of the Tang Dynasty, there were methods such as rice frying, fire simmering, vinegar boiling, etc., and now it is the beginning of the Tang Dynasty, so Zuo Shaoyang estimates that they should still use the ash artillery burning method, and sure enough, they guessed it.
