The fragrance of medicine is alluring, the farm elder sister is cool and cool

The second prince, Mo Lianjin, stood up and walked towards Wen Qingcheng. His cold gaze made her feel uncomfortable. "Pharmacist Wen, you haven't replied to the princess yet. How did you know?"

Wen Qingcheng said slowly, "Princess, Second Prince, I have actually studied this medicine a long time ago, but I just haven't found the time to make it. I also found that boiling willow bark in water can relieve fever and pain, and I have studied the purification method."

Ling Du stepped forward and said, "Princess, Second Prince, Pharmacist Wen heard from me that Liu Dan is made by boiling willow bark in water, so she said she had also studied it."

Princess Anle looked at Ling Du and then at Wen Qingcheng, and asked, "Since Pharmacist Wen has studied this medicine, do you have any ideas for improving it?"

Princess Anle was indeed amazed by the miraculous effect of Liu Dan, and she liked this medicine very much. However, although this medicine is good, it irritates the stomach. If there is a way to improve it, it will be perfect. However, Princess Anle did not have high expectations for Wen Qingcheng. After all, she was too young, had no master, and no family inheritance. Even Ling Pharmacist, who was born in a pharmaceutical family, could not solve the problem, so how could she, a little girl, know it?

Just as the thought flashed through his mind, Wen Qingcheng's clear voice rang out, "Princess, the main ingredient of Liu Dan is salicylic acid, which is extracted from willow bark. However, salicylic acid is very irritating and needs to be improved into acetylsalicylic acid to reduce the irritation to the stomach."

Everyone looked at each other, and the third prince Mo Lianyi looked at Wen Qingcheng with a complicated expression. Crown Prince Mo Lianche looked at Wen Qingcheng with an exploratory look, as this girl always gave him a refreshing feeling.

The pharmaceutical masters present all discussed in low voices. No one understood what Wen Qingcheng said, including Mo Jinghong, who was also confused. Although he didn't know how to make medicine, he had been managing He's for a long time, and he was familiar with some pharmaceutical terms, but he had never heard of what Wen Qingcheng just said. How did his little girl know that? It seemed that he really didn't understand her at all.

The Queen, who had been silent, said, "I have never heard of the acetic acid that Pharmacist Wen mentioned. Does that mean you can improve it?"

Everyone's eyes were once again focused on Wen Qingcheng. Wen Qingcheng had indeed made acetylsalicylic acid in her previous life, but in the Great Qi Dynasty, she was concerned about the material problem. If there were ready-made materials, she could make it. "Your Majesty, I can make it. What I made is acetylsalicylic acid, and I named it aspirin. In addition, I am considering adding special excipients to make the drug insoluble in the stomach, to minimize its irritation, and change it to enteric-coated."

Minghua, the owner of Minghua Pharmaceutical, and Lingdu looked at each other, and Lingdu's lips moved slightly with a guilty conscience. This recipe was not originally created by him, but by Lu Qiuyu, who now retired behind the scenes. Although he participated in the pharmaceutical process of Liu Dan, he did not know much. Now it seems that Wen Qingcheng knows more than him, as if Minghua plagiarized He's.

The second prince, Mo Lianjin, stretched out his slender fingers, touched a Liudan in the medicine dish, and looked at Wen Qingcheng. "Pharmacist Wen really has a brilliant idea, but I believe that no one present understands what Pharmacist Wen said just now. So how to improve it, please tell me, Pharmacist Wen. Could it be that Pharmacist Wen just had an idea and said that Liudan was discovered by Pharmacist Wen first?"

Mo Lianjin saw that Princess Anle really wanted Liu Dan. If Wen Qingcheng hadn't jumped out to point out Liu Dan's shortcomings, Princess Anle would not have cared. In the current situation, if Wen Qingcheng had a way to improve it, and if the emperor asked Wen Qingcheng to improve the medicine, then who would own the Liu Dan?

Wen Qingcheng replied with a smile: "It's not difficult. You can use acetic anhydride as the acylating agent and citric acid as the catalyst. After salicylic acid and acetic anhydride react, you can get crude acetylsalicylic acid by filtration. Then add sodium bicarbonate and hydrochloric acid solution to get acetylsalicylic acid."

After Wen Qingcheng finished speaking, everyone was stunned for a moment. Ling Du frowned, listening to Wen Qingcheng's well-reasoned improvement method. He only regretted that he had no pen and ink to write it down. He could only hold his breath and concentrate on memorizing it in his mind and tell Lu Qiuyu when he got back. However, what Wen Qingcheng said were all unfamiliar words to him, and he couldn't remember them clearly.

"I never thought that Pharmacist Wen is so knowledgeable. Perhaps even you people in the Imperial Pharmacy have never heard of what Pharmacist Wen said today." After the emperor said this, he looked at Wen Qingcheng thoughtfully, and an idea secretly emerged in his mind.

At this time, the eunuch in charge came to report that the time had come and asked whether to start the banquet. Princess Anle did not want to embarrass the people of Minghua Pharmaceutical, so as to discuss the selection of the champion later, she smiled and said, "Time flies, it's already noon, and I'm hungry too."

The queen also laughed and said, "Hurry, let's start the banquet."

Everyone moved to another hall, and the palace banquet began. Dancers in colorful feathered clothes came on stage, playing the zither and dancing gracefully. Just as everyone was watching the performance attentively, the queen mother suddenly fell to the ground with rapid breathing. At once, the eunuchs and palace maids knelt on the ground and surrounded her, shouting loudly: "Queen Mother, Queen Mother, please wake up."

The emperor and the empress saw the queen mother fainted, so they stood up and went to check. The emperor shouted, "Quickly call the imperial physician!"

The dancers and musicians in the hall also left the stage. Several eunuchs and palace maids ran to find the imperial physician, and the scene was in chaos.

"Grandmother..." Princess Anle called out.

Wen Qingcheng, a doctor, left her seat and ran forward. She saw the empress dowager covering her heart with her hands. She was having trouble breathing and her lips had turned blue. This was an acute attack of angina pectoris. Wen Qingcheng reached for the bottle of quick-acting heart-saving pills in her lapel.

Wen Qingcheng knew very well that heart attack like this could be cured within minutes. If she waited for the imperial physician to come and prescribe medicine, the patient might not be able to take it.

"Why hasn't the imperial physician arrived yet? Go and check it out." The second prince shouted to the eunuch beside him.

"Your Majesty, the Queen Mother is in critical condition. This medicine is a quick-acting heart-saving pill, which is exactly what the Queen Mother is suffering from. Please let the Queen Mother take it."

Wen Qingcheng couldn't squeeze into the front row, so she stretched out her hand and put it directly in front of the emperor's face.

The emperor turned around and saw that it was Wen Qingcheng. He had just learned about Wen Qingcheng's talent. Just as he was about to take the medicine, the third prince Mo Lianyi stopped him, "Father, wait a minute, the queen mother's body can't afford any mistakes. This medicine was just selected and eliminated." Mo Lianyi looked at Wen Qingcheng and shouted, "If the queen mother gets sick from taking it, can you bear it!"

Several people in the front row automatically made room for Wen Qingcheng to come over. Seeing the empress dowager twitching all over, the emperor became anxious, "Are you sure? If you can't cure it, you will be punished."
