Zuo Gui was a little hesitant to set up a stall in the city to see a doctor, it was still a face problem, but after yesterday's experience of patrolling the doctor, he had already had a sense of understanding of the bell doctor, and he didn't feel ashamed, and he made more money than sitting in the lobby and waiting. If you go out and set up a stall, you may be able to make some money for the New Year.

Thinking of this, Zuo Gui nodded and said, "Okay, then ......, let's go to Washi to set up a medicine stall." ”

In the Tang Dynasty, shops could be opened on both sides of the street, but without stalls of shops, they could only be concentrated in the fixed commodity market, which was called East City and West City in Chang'an, the capital city, and Washi City in local prefectures and counties.

Hearing that the two of them were going to set up a medicine stall in Washi, Liang hurriedly borrowed a cart from the grocery store opposite, put a table and three chairs on it, Zuo Shaoyang put the medicine box on it, pushed the cart, and followed Zuo Gui through the streets and alleys to Washi.

There was no one in the tile market early in the morning, so the two of them found a place, put the tables and chairs away, tied the signboard to the table legs and erected it, and waved it in the wind. The two of them sat down in chairs and waited for the patient to seek medical attention.

The number of people in the tile market gradually increased, all kinds of stalls were opened, and those who bought New Year's goods from the countryside outside the city and went to the market also came.

When choosing the land just now, Zuo Shaoyang deliberately chose a place close to the firewood picker to see if he could see the dark-skinned firewood girl. Thinking of the girl, he took out the little squirrel in his bosom and looked at it, and took out a pine nut from his pocket and fed it.

The people who sell firewood are almost all picked up from the countryside into the city, starting in the morning, generally arriving at noon, now is the morning, only a few firewood picks are placed there in the morning, trying to grab an early morning business, but the price is relatively expensive, and no one buys it. Zuo Shaoyang paid attention to it, and there was no dark-skinned girl inside. Presumably, the family is far away, and it takes some time to carry firewood into the city.

After waiting for a long time, no patients came to the doctor. Zuo Shaoyang was very bored, and saw that there was a stall of wholesale medicinal materials not far away, so he said to Zuo Gui: "Dad, I'll go to the medicinal materials and have a look." Call me if you have something. ”

"Hmm." Zuo Gui caged his sleeves and shrunk his neck, feeling a little depressed. I didn't ask him what he was doing at the medicine stall.

There are six counties under the jurisdiction of Hezhou Prefecture, and the state government is Shijing County. There is the largest wholesale market of medicinal herbs in the whole Hezhou Prefecture in the city, which is located in the city's bazaar. The scale of this wholesale market is still relatively large, not only the medicinal herb merchants and pharmacies in the six counties of Hezhou have come here to buy medicinal materials in wholesale, but even the prefectures and counties near the left have come to buy, so the business is still relatively prosperous.

The wholesale medicinal herb market is still in the second place, and the most important ones are several large wholesale firms, which are located at the entrance of Washi.

Zuo Shaoyang didn't buy medicinal materials, so he didn't go to the medicinal material trading house at the door, but only went to the medicinal material wholesale booth to take a look. There were many houses in the past, and the types of medicinal materials were quite uniform. He looked carefully at the past one by one, paying special attention to the medicinal materials that he didn't have at home, and found that everything that he didn't have at home was relatively valuable medicinal materials.

After looking at all the stalls of medicinal materials, he found that there were no stalls for some commonly used medicines, such as "red peony", "myrrh", "green skin", etc., and recalled carefully that these medicinal materials should have been used as medicinal materials after the Song Dynasty, so there was no trace of them in the medicinal materials market.

He memorized these common medicines that did not appear in the Tang Dynasty, because many prescriptions of these medicines would be used, and he had to find a way to find these medicinal materials, otherwise some of the prescriptions that used the new medicines that appeared in later generations after the Tang Dynasty would not be able to be used. Then the loss is great.

After he wrote down all these medicinal herbs, he returned to Daddy Zuogui's stall, and still no customers came.

After waiting for more than half an hour, it was almost noon, and finally the first customer came.

This customer is the child of a woman who sells vegetables diagonally, followed his mother to pick vegetables into the city to sell, originally sat diagonally opposite the very well-behaved nothing, after a while, he said that he had a stomachache, went to the toilet and came back, or had a stomachache, cold sweat broke out on his forehead, the peasant woman who sold vegetables was anxious, and hurriedly entrusted the care stall next to him, and pulled the child to find Zuogui and them to see the disease.

Zuo Gui asked the child to sit down and asked, "Did you eat anything unclean earlier?" ”

The peasant woman helped, "I haven't eaten anything, I haven't eaten since the morning, and I'm thinking that I'll sell the vegetables and buy some things for the New Year and go back for lunch." ”

Zuo Gui looked at the child's yellow face and thin muscles, and his small belly was bulging, which should be ascariasis, and asked, "Did the child take medicine to fight worms?" ”

"Yes! Yesterday afternoon, I looked for Lang Zhong in the village and said that there were bugs. I prescribed pills and gave him worm medicine last night. ”

"Oh, what did you eat?"

"I don't know either, it's the medicine prescribed by Langzhong in our village, it's a pill, oh, I have a few pills left." The peasant woman said, took out two pills the size of chopsticks from her arms and handed them to Zuo Gui, "This is it." ”

Zuo Gui took it and looked at it, licked it on the side of his mouth again, then spit out a mouthful of saliva, and said, "This is a thunder pill, an insecticide." How much do you give your child food? ”

"Lang Zhong said to take three pills three times a day."

"How many grains did you give the child?"

"Well, five. The child always had stomach pain, and Lang Zhong said that there were worms in his stomach and he had to fight worms, and I was afraid that I would not be able to beat them, so I gave the child two more grains. ”

"Thunder pills are poisonous, children can't eat more!"

The peasant woman was taken aback: "Huh? Poisonous? Lang Zhong didn't say that! ”

"It's poisonous, "Shennong's Materia Medica" is clearly written, this medicine is poisonous, and you can't take more."

Lei Pill is a broad-spectrum anthelmintic drug, roundworms, tapeworms and other intestinal parasites can be killed, and it is noted in the "Shennong Materia Medica" that Lei Pill is poisonous. However, modern medicine has found that thunder pills are actually not poisonous, or they are not toxic at normal doses, and the normal dose of raw thunder pill powder Chengren should reach 60 grams at a time, and young children need to take 30 grams at a time to achieve the insecticidal effect. And you have to take it three times a day. No cases of poisoning have been reported at this dose. In the case of ginseng, this dose would have had adverse reactions long ago. Lei Pill does not, so the safe dose of Lei Pill is far more than many traditional Chinese medicines, and it is a very safe insecticide.

However, because the "Shennong's Materia Medica" says that thunder pills are poisonous, many doctors have trembled about the use of thunder pills throughout the ages, and they dare not use them more, for fear that they will be poisoned by patients if they use too much. Many anthelmintic drugs in traditional Chinese medicine do not kill intestinal parasites, but paralyze the insect body, so that it cannot attach to the small intestine of the human body, so that the insect body is excluded from the body with the peristalsis of the intestine, but Lei Pill is different, it is an insecticide in the real sense, which can not only kill the insect body, but also decompose the insect body into pieces!

Lei pill and other traditional Chinese medicine anthelmintic drugs, there is a common feature, that is, the dosage must reach a certain dose, in order to produce an insecticidal effect, if the dosage can not be reached, the patient's stomach those poisoned but not dead roundworms, tapeworms, will be painfully in the patient's stomach struggled and rolling, if entangled into a clump, will form roundworm surname intestinal obstruction. If it enters the biliary tract, it can cause cholecaris and may even penetrate the small intestine, so it is very dangerous.

Due to the insufficient amount of medication, the drug stimulates the worm body, causing it to move agitated in the intestines, and the child has abdominal pain. It is not possible to kill insects when the insect body is restless, otherwise the insects in the body are dying and struggling, and accidents are easy to occur. At this time, the worm must be planted first. Then repel the insects.

The woman heard Zuo Gui say that the thunder pill was poisonous, and she was so angry that her mouth was crooked: "Oh, among the thieves who killed this god, use poison for my son!" This ...... that kills a thousand knives! ”

Zuo Gui listened to him scolding Lang Zhong in the village, his heart was unhappy, and he stroked his beard and said: "You can't say that, it is a three-point poison, many medicines are poisonous, as long as it is used properly, poison can also become a good medicine." Just can't overdo it. This thunder pill is a good medicine for children to fight insects, and Na Langzhong did not use the wrong medicine. If your child has a stomachache, it should be that you have given your child too much medicine. You can't blame the family. ”

Listening to Zuo Gui helping Langzhong in the village, the peasant woman didn't dare to scold anymore, and hurriedly begged Zuo Gui to save the child.
