"Only Qinyiyuan has received that kind of medicine?" The anger in Jiang Xuan's eyes was already very obvious.

Lu Qingrong nodded: "According to the records archived by the prescription, this is indeed the case. ”

Jiang Xuan confirmed: "Is it certain that the poison in my mother is all because of the extra medicine in the residue?" ”

The matter is very important, Lu Qingrong doesn't know much about pharmacology, and he doesn't dare to judge lightly, so he only said truthfully: "I was afraid that I would startle the snake, so I didn't dare to ask the imperial doctor, but I just asked Mo Nan to take it to the outside pharmacy to ask, and the statement I got was inevitably simple and general......

"Someone!" Jiang Xuan immediately shouted, "Go and ask Doctor Xu to come over!" ”

In the middle of the night, Lu Qingrong didn't stop him.

After all, this matter has been haunting their hearts for many years, and at this time, they have finally looked forward to the clue, and no one can wait any longer.

Not long after, Xu Yizheng arrived at Yuyuan.

was invited in the middle of the night, and Xu Yizheng was at a loss, not knowing what was going on.

Yesterday, Mrs. Shizi fainted, it was not a major symptom, not to mention that the prescription she prescribed was very proper, so there should be no problems......

Walking into the flower hall of Yuyuan, Xu Yizheng felt that something was even more wrong.

Different from the previous visits, not a single serving maid in the house could be seen, only the prince and the lady of the prince, sitting upright on the main seat, with a stern expression.

Doctor Xu has been practicing medicine for many years, and at this time, it is not difficult to notice that although both of them have calm faces, they do not see any signs of physical illness.

At this time, Jiang Xuan took the lead in speaking:

"I asked Doctor Xu to come over so late, I really have a question I want to ask. I hope you don't mind! ”

Xu Yizheng immediately gave up, and said "don't dare" several times, and slandered in his heart at the same time. I'm really used to it, every time Mrs. Shizi feels a little unwell, she will inevitably be called by a roar......

Soon, he noticed the difference.

Jiang Xuan put a few medicine bags on the square coffee table beside Xu Yizheng, picked up one of the small bags with his own hands, opened it, and handed it to Xu Yizheng.

"You can help me take a look. What is it? Jiang Xuan asked.

Doctor Xu took it respectfully and looked at it carefully.

After a while, I felt a cold sweat break out in my palms.

I saw these old dregs. It's been dry for a long time, and it looks like it's been a long time, but Rao is like this, and he can still clearly tell what it is.

Xu Yizheng did not reply immediately. Instead, I thought to myself in my heart.

For many years, he has been circling among the nobles and nobles in the palace. When it comes to the tricks of the harem and the inner house, no one knows better than him.

At this moment, although it was just a medicinal herb that was not uncommon in front of him, thinking of the urgency and sternness of the third watch of the Marquis of Jingyuan, and the fact that this medicinal residue seemed to have been preserved for at least ten years...... Xu Yizheng suddenly guessed something.

He couldn't avoid it, so he had to be as cautious as possible and said: "This medicine is the root of the cotton, also known as the root of seven hemp or the grass of nine letters, if used properly. It can play a role in clearing inflammation, detoxification, and dispersing stasis, and also has an effect on asthma and many other diseases. ”

Jiang Xuan and Lu Qingrong listened carefully.

This is the content that Lu Qingrong inquired about. It's not much different.

Xu Yizheng stopped here, and the expression on his face was abnormal, as if he wanted to speak and stopped.

"If Xu Yizheng has any other opinions, you might as well say it directly." Jiang Xuan was a little anxious.

Xu Yizheng simply said bluntly: "It is three points of poison, and the toxicity of this cotton root is a little more, if you want to avoid it from hurting people, in addition to prescribing the right medicine, there are two points that need special attention." ”

"First, the dosage should be strictly controlled, and not too greedy; Second, this medicine can be decocted for a long time to make it non-toxic, otherwise the reaction will be very great. ”

Doctor Xu paused, glanced at the medicine residue in his hand, and then continued: "Judging from this medicine residue, if this is the amount of medicine boiled once, no matter what kind of symptom it is used for, it is too much." And...... Obviously, the frying time is not enough, and the toxicity has not gone. ”

Speaking of this, Doctor Xu picked up another medicine bag from the coffee table beside him and observed it for a moment: "Dare to ask the prince, this bag of medicine residue is in the same place as the cotton root in the field?" ”

Jiang Xuan nodded and asked, "Is there something wrong?" ”

Doctor Xu showed his doubts: "This is an ordinary body-tonic prescription, which can calm the mind and nourish qi, the medicinal properties are mild, decent, and there are not too many requirements for the physique of the person taking the medicine, and there is no toxicity at all." It's just that there shouldn't be a cotton root in it anyway, let alone such a large dose...... Shi Ziye, are you sure this is from the same pot of medicine? ”

"Yes." Jiang Xuan's face became more and more gloomy, "So is this poisonous very powerful?" ”

Xu Yizheng did not hide it: "As I said just now, if you fry for a long time, you can be safe." But judging from the residue, the time spent boiling on the cotton roots in this is far from enough. Moreover, if these medicinal residues really come from the same pot of medicine, it can be asserted that the cotton roots were put in when they were halfway through boiling, and because their properties have changed very little, they are definitely not put in the pot with other medicinal herbs......"

Xu Yizheng's tone was very affirmative.

It turned out that the cotton roots in this field were added by people!

Jiang Xuan and Lu Qingrong looked at each other in unison, and they both saw a complicated state of mind in each other's eyes, with Ran, sadness, and anger.

Jiang Xuan's feelings were even more difficult to control, and he was a little speechless for a while.

Lu Qingrong asked: "As you said, there is an extra medicine in it, and the toxicity has not disappeared, so ...... What will happen after taking it? ”

"Depending on the patient's physique, diarrhea can be difficult to stop, and it can be ...... Life-threatening. ”

Doctor Xu was becoming more and more cautious, seeing that the anger of the Marquis of Jingyuan could no longer be concealed, he was almost sure who this "patient" was referring to.

Sure enough, there was a sudden loud noise in his ears, and it was the heavy fist of the Marquis of Jingyuan who fell on the table.

Lu Qingrong didn't step forward to stop her, she knew that Jiang Xuan needed to vent at this time.

Diarrhoea...... Life-threatening......

This is extremely consistent with Mrs. Jiang's symptoms back then.

Lu Qingrong was angry, but also a little happy.

God has eyes, Mrs. Wu took such pains to destroy the evidence, set fire to the small kitchen, and removed all the relics of Mrs. Jiang from the house...... In the dark, these evidences were preserved.

Lu Qingrong fell into deep thought.

Jiang Xuan was also silent.

Doctor Xu was looking left and right, a little at a loss, and said goodbye several times, but the two of them were focused on their thoughts and didn't hear it.

After Xu Yizheng gave a salute, he withdrew on his own.

After another half a while, Jiang Xuan came back to his senses, and he was about to leave the house without changing his clothes.

"Let's not startle the snake, you rest first, I'll go to Lord Sun, this matter must have a result within two days!"
