Li Zhiyun saw the little girl standing there crying, and hurriedly stepped forward, "What's wrong with you?" The little girl looked at him with teary eyes, and said with tears: "Our young lady was bitten by a snake. When Li Zhiyun heard this, he was taken aback, and hurriedly said, "When did it happen?" ”

"Just now."

Li Zhiyun turned to the young lady and said, "Where is the bite?" Let me see, shall we? The young lady was speechless in pain, but nodded and pointed to her right foot and neck. Li Zhiyun helped her to sit down on the stone next to her, took off her shoes and socks for her, pulled up her trouser legs, and revealed her white jade feet.

The wound from the snake's bite was on the ankle, with two deep tooth marks, oozing purple-black poisonous blood outward. The skin around the wound began to bluish purple. Li Zhiyun raised his head and said to Yahuan: "Is there a bandage?" ”

"There's a rope." As she spoke, she walked over to a basket that had been thrown on the ground next to her, took out a piece of rope and handed it to him.

Li Zhiyun took the rope, tied the young lady's legs and stomachs tightly, then lifted her feet up, leaned down and sucked the poisonous blood with her mouth. He sucked in and spit until the blood from the wound turned red, and then he stopped sucking. Then he took a handkerchief from the lady and bandaged the wound.

Li Zhiyun stood up and said, "Okay, it should be fine." The young lady put down her trouser leg and blushed and said, "Thank you, Childe." Li Zhiyun turned his head and saw that the basket was full of herbs, so he asked, "You went up the mountain to collect medicines?" Yahuan hurriedly nodded yes.

The young lady put on her shoes and socks and stood up, but as soon as her right foot hit the ground, she still cried out in pain. When Li Zhiyun saw it, he thought forget it, let's help others to the end, so he turned his head and said to Yahuan: "Where is your home?" I carried Miss back. The little girl was very happy when she heard this, and hurriedly pointed with her hand: "It's not far." Climb over the mountain beam in front of you and go down the mountain. ”

When the young lady heard that Li Zhiyun wanted to carry herself home, she didn't refuse, but just shyly: "Then there is Lao Gongzi." Li Zhiyun carried the young lady on his back, and Liu Shuyi carried the bamboo basket on his back, and under the leadership of Xiao Yahuan, he walked down the mountain. In the past few years, Li Zhiyun has gotten up early every day to practice martial arts, and his body has become a lot stronger, and the young lady's body is very light, so it is not difficult to carry it at all. Halfway through, Liu Shuyi proposed to replace him, and Li Zhiyun said: "Your leg injury is not completely healed, so let me come." ”

A few people went down the mountain, and a village appeared in front of them, about hundreds of families, but they saw that "the hedges were sparse and deep, and the trees were not yet green." The shepherd boy returned to the back of the ox, and the piccolo played without a cavity. "The rustic style and ancient style are blowing in the face, which is really refreshing. After they entered the village, they came to the door of a farmhouse, and the little girl pushed open the firewood, welcomed the guests in, and then shouted at the house: "Master, master." ”

Suddenly, an old gentleman in his fifties walked out of the room. He had a clear countenance, a strong spirit, and a long gray beard. When the old gentleman saw Li Zhiyun carrying his daughter on his back, he was quickly surprised: "What's the matter?" ”

"Miss was bitten by a snake, and it was this son who saved Miss." Yahuan replied crisply.

The old gentleman hurriedly stepped forward and said, "Thank you, son, put the little girl down." After Li Zhiyun put down the young lady, the old gentleman stepped forward to hold his daughter's arm and said to Li Zhiyun: "The old man sent the little girl back to the room, and asked the two sons to rest in the hall first." Xiaoyun, serve tea to the guests. ”

Li Zhiyun and Liu Shuyi walked into the hall under the leadership of Yahuan. The area of the hall is not large, and the furnishings are very simple, but they are cleaned up neatly and the windows appear to be bright and clean. On the wall of the front, there is a large plaque with a black background and mud gold, on which are written four big characters of "hanging pot to help the world". Needless to say, the owner of this family is a Langzhong.

Yahuan went out after making tea for the two of them, and Liu Shuyi also said that he was going to go out for a walk, and only Li Zhiyun was left in the hall. After he had sat there and finished a bowl of tea, the old gentleman came in through the back door.

Li Zhiyun hurriedly stood up and said with concern: "Miss is it okay?" The old gentleman nodded and said, "Thanks to the son's proper handling, the old man gave her some medicine, and now it is fine." He said that he invited Li Zhiyun to sit down, and then sat down opposite, looked at the other party and said, "Dare to ask Gongzi's surname?" ”

"The junior is surnamed Li."

The old gentleman nodded and said, "Gongzi Li, the old man's surname is Wang, his ancestors have practiced medicine for generations, and he opened a clinic in Lucheng, but he moved to live in this Phoenix Village because he was avoiding the war. The old man is only this one daughter, and he treats him like a pearl in the palm of his hand on weekdays, only because the old man has recently had a cold and is unwell, and a patient is in urgent need of a taste of herbs, the little girl took the girl ring up the mountain to collect medicine, and did not want to be injured by poisonous snakes. ”

Li Zhiyun waved his hand and said, "Mr. Wang doesn't have to be polite. Mr. Wang is an ancestral medical skill, and he must have a deep family education. The junior happened to have something unclear and wanted to ask Mr. Wang for advice. ”

"Li Gongzi has something to say, but it doesn't hurt to say it."

Li Zhiyun pondered for a moment and said, "Don't hide it from Mr. Wang, my brother recently had malaria miasma and was diagnosed and treated by a doctor Jia. However, Dr. Jia used all the prescriptions for malaria, but his brother's condition never improved. The younger generation accidentally learned that in Ge Hong's "Elbow Reserve Emergency Prescription" of the Eastern Jin Dynasty, there is a side of Artemisia annua to treat malaria, and it is said that Artemisia annua is particularly effective in treating malaria. However, Dr. Jia applied the medicine according to the prescription, but my brother's condition still did not improve, I don't know why? ”

After hearing this, Dr. Wang smiled and said, "Artemisia annua is indeed a good cure for malaria, but it still needs to be carefully screened before it can be proper." Li Zhiyun didn't understand, and hurriedly said, "Could Mr. Wang please be more detailed?" Dr. Wang pondered for a moment and said: "Artemisia annua is called differently due to time and place, and the Artemisia annua recorded in Ge Hong's book is not the Artemisia annua mentioned in the world today, but Artemisia annua. Artemisia annua is also called Artemisia annua, and Artemisia annua is also called Artemisia stinky and Artemisia bitter. That Dr. Jia may not have figured out the difference between Artemisia annua and Artemisia stinky, and using Artemisia annua as medicine naturally worked to no avail. As a doctor, you should not stick to books, but should be diligent in practice and carefully distinguish the medicinal properties of various medicinal materials, otherwise you will inevitably miss the slightest difference. ”

After Dr. Wang's explanation, Li Zhiyun suddenly opened up. It turned out that it was not Artemisia annua (Artemisia annua) that could treat malaria, but Artemisia skunensis, that is, Artemisia annua. Li Zhiyun is right when he thinks about it carefully, the Eastern Jin Dynasty where Ge Hong is located has been hundreds of years ago, and the names of many things have changed. He estimated that Dr. Jia did not believe in Ge Hong's recipe, so he did not study the prescription of Artemisia annua for malaria in detail, so he could not distinguish the difference between Artemisia annua and Artemisia annua.

In this way, Artemisia annua does not contain artemisinin, and the one that contains artemisinin is Artemisia annua. The artemisinin refined by Tu Youyou for the treatment of malaria should not be called artemisinin, but artemisinin. It is only because Ge Hong's book records Artemisia annua, so it is called artemisinin according to his statement.

The mystery in Li Zhiyun's heart was finally solved, and he was suddenly in a cheerful mood. Next, he wanted to find out what Artemisia annua looked like, so he said, "Mr. Wang, do you have Artemisia annua in your house?" Can you take a look? After hearing this, Dr. Wang stood up and said, "Master Li, please come with me." Li Zhiyun thought that Dr. Wang was going to take him to the pharmacy, but Dr. Wang led him out of the house and to the outside of the courtyard.

Doctor Wang pointed to the blue-green wild artemisia trees that grew more than one meter tall next to the courtyard wall, and said, "Master Li, this is Artemisia annua." In the "Book of Songs", it is said: "Yo Yo Lu Ming, Artemisia Eating Wild", referring to this kind of bitter artemisia. ”

Li Zhiyun's eyes widened in surprise, this is the yellow artemisia that can treat malaria? That's too ordinary, isn't it? The countryside is everywhere, in front of the house, behind the house, by the pond, beside the path, everywhere grows this wild artemisia seed. Farmers often feed it to pigs, and even pigs don't like to eat it.

Doctor Wang said with a smile: "Li Gongzi, do you think it is too common and inconspicuous?" In fact, it is not difficult to find all useful medicinal materials, which is probably God's favor for human beings. ”

After solving the mystery of Artemisia annua, a stone in Li Zhiyun's heart finally fell to the ground. He wanted to rush back to Gujing Village immediately to treat his second brother, but it was late, the mountain road was difficult to walk, and Dr. Wang repeatedly tried to stay, so they had to stay for one night.

Early the next morning, Li Zhiyun and the others said goodbye to Dr. Wang and left Fenghuang Village. The two of them have long been lost, but it doesn't matter, as long as they find Shun'an Town, they will be able to find their way back to Gujing Village. Before leaving, Li Zhiyun asked Dr. Wang about the location of Shun'an Town, and Dr. Wang told him the walking route in detail. They followed the route told by Dr. Wang and finally found Shun'an Town.

As soon as Li Zhiyun and Liu Shuyi walked to the side of the town, they saw a few people running out of the town from a distance. When those people ran closer, Li Zhiyun took a closer look, and it turned out to be Zhang Zheng and Cai Hu.

Zhang Zheng ran to them and said with a smile: "Lord Wang, Liu Gongzi, are you back?" Li Zhiyun was surprised: "Why is it so coincidental?" Zhang Zheng explained: "A few of us resisted for a while, and then retreated. Later, I went up the mountain to look for you, but I didn't find you. We thought, you'll be back. So, when the enemy force is gone, we will go back to the town and wait for you. ”

Li Zhiyun listened, nodded, and said, "Okay, let's go back to Gujing Village." Cai Hu on the side said: "Lord Wang, aren't you going to find Lang Zhong?" Li Zhiyun waved his hand and said, "No need to look for it, I know how to cure my second brother's illness." When Zhang Zheng heard this, he was pleasantly surprised: "Really? That's great! ”

The group returned to Gujing Village along the same road. When entering the village, Li Zhiyun pulled a handful of wild artemisia seeds on the side of the road. Zhang Zheng saw it and said strangely: "Lord Wang, what are you doing with it?" Li Zhiyun said with a smile: "You'll know later." ”

Li Zhiyun returned to his residence and saw that his second brother was still unconscious, so he handed over the yellow artemisia to Dr. Jia and asked him to give the second brother the juice according to Ge Hong's recipe. Dr. Jia didn't dare to ask more, so he had to do the same.
