Ye Caitang has a certain amount of research on drugs, or in other words, a certain amount of research on ingredients. But it is not limited to traditional Chinese medicine, nor is it proficient in traditional Chinese medicine, but it is still necessary to listen to the master.

Yue Qi asked someone to bring in a few packets of medicine: "For example, in our store, the common ones are ephedra, cimicifuga, licorice, angelica, lobelia, if you take it in small doses for a long time, it may cause symptoms of heart palpitations and dizziness." ”

I have heard of these herbs Ye Caitang, and angelica licorice is like Yue Qi said, it is common among the common, which pharmacy has it, and sometimes it is in the soup stock for making soup.

Yue Qi said: "If it is a medicinal material that is not commonly used, and it has some poisonous properties, if someone buys it within a few months, the guy will definitely have an impression, and there may be a record." However, there are many sales of these medicines every day, and it is really impossible to find out. ”

Yue Qi said truth-seeking, and Ye Caitang couldn't help nodding.

Don't say that Yue Qi can't give the list, even if it is given to you, fifty people a day buy it, and one thousand five hundred people a month buy it, it's useless to give it.

Ye Caitang's furrowed brows suddenly relaxed: "In the Yao Mansion, in the past three months, has anyone come to buy these medicines?" ”

"There must be that." Yue Qi didn't need to look at it and said: "The master in Yao's mansion, Master Yao, Mrs., several young masters, young masters, and aunts, are all in our shop to see a doctor and take medicine." I have to go there several times a month, and although the recipes are different, these herbs are also available. ”

"No, no, no, that's not what I meant."

Ye Caitang said: "I mean, does anyone in the Yao family use medicine for a long time, and her prescription has exactly one of these medicinal herbs." ”

Yue Qi was stunned for a moment and said a little later.

He got up and flipped out a booklet in the cabinet, which was the Yao family's account book.

"The Yao family is an old customer, we have a record of which person's health is and what medicine they take all year round." Yue Qi opened the booklet, and Ye Caitang also came over.

Sure enough, I remember it very clearly, every consultation, every prescription, and time are written very clearly.

"There it is." Yue Qi pointed to one of the lines: "Yi Kidney Tong Jing Soup, this is what Master Yao's eighth aunt takes every day." She has the disease of sunflower water imbalance, every time the sunflower water has unbearable abdominal pain, long-term use of this prescription, has the effect of tonifying the kidney and calming the heart, invigorating blood and meridians. ”

Yao Haifeng's eighth aunt, that was the last person he saw before he died, and Sa Youxin who is still locked up in the room.

When Ye Caitang went to see Sa Youxin before, he did see that her sunflower water was out of tune and her abdominal pain was unbearable. said that she had been taking medicine to recuperate, but in the past few days, no one has delivered medicine to her.

Ye Caitang's eyes lit up and went to see the recipe.

Yue Qi said: "In this Yi Kidney Tong Meridian Soup, there is a medicinal herb of Angelica. If this herb is taken for a long time, it can cause heart disease. ”

Ye Caitang didn't know about the strange goods, but Angelica still knew.

It contains natural coumarins, which can cause severe bleeding, so it is contraindicated in patients with cardiovascular disease. If used for a long time, it can cause heart disease.

Yue Qi said: "However, her symptoms are very serious, and after taking the Yi Kidney Tong Jing Soup for a few months, the effect is not obvious. I was thinking about changing the dressing, but I didn't expect it to happen. ”

Obviously, Yue Qi also understands that Yao Haifeng is dead, and his aunts and wives will have a good life. In the future, I am afraid that I may not have the opportunity to let him go to the outpatient clinic again.

Ye Caitang gained a lot this time, took a few pieces of prescription and angelica, and didn't return to the six doors, so he went to Yao's house in a hurry.

In the past few days, she has been to Yao's house several times in a row, and the housekeeper knows her, knowing that she is a person from the six doors, and without saying a word, she will ask someone to lead the way, where she wants to go.

"Go to the place where the medicine is boiled." Ye Caitang said: "The former lord and aunt in your house, if they need to boil medicine, where are they?" ”

The maid said, "Small kitchen." Next to the big kitchen, there is a small kitchen dedicated to boiling medicine. ”

There is medicine boiling in the small kitchen now, and before I reached the door, I smelled a strong smell of medicine.

The maid explained: "The medicine in the house is boiled in the small kitchen, but there is no one who specializes in boiling medicine. It's all the medicine of which yard, which yard is watched by others, otherwise you have such a request, he has such a request, and it is easy to go wrong. ”

Ye Caitang nodded and went in.

I saw that in the purple sand jar on the stove, a little girl was guarding the side. When I saw someone coming, I was timid and let go of it.

Ye Caitang said: "Your deceased Master Yao, who boiled his usual medicine, call someone to me to ask a few words." ”

The maid was busy.

"There is also the eighth aunt Taisa Youxin, I heard that she has also been taking medicine for a long time, so I called the person who boiled the medicine for her."

Soon, a few maids came.

Yao Haifeng's courtyard is okay, the two maids in Sa Youxin's atrium are also haggard these days, Sa Youxin is suspected of being a murderer, and they are naturally suspected of being accomplices, they can't eat or sleep well.

Ye Caitang asked them: "Master Yao and Eighth Aunt Tai's daily medicine are respectively responsible for you, so when you boil the medicine, do you not leave one step?" ”

Several people shook their heads.

Although the Yao family is rich, it really can't do this.

The maid explained: "Some medicines take an hour or two or even longer to boil, and if we keep watching from the sidelines, we will be said to be deliberately lazy." So just take a look at it every once in a while and don't let the water dry. ”

"Then Master Yao's medicine, and Aunt Yao's medicine, are you together with the time to boil the medicine?"

The more these questions were asked, the more nervous everyone became, as if something was about to come out.

"It's all in the afternoon, and it's all in the evening." The maid said in one breath: "The eighth aunt has been in the door for a short time, and she is well-read and gentle, and the master has spent most of the time in the eighth aunt's room for the past few months, and often drinks medicine together." ”

If you omit those causes and consequences, it is really a bit of husband and wife love.

Ye Caitang probably had an idea.

"When you boil the medicine, does Aunt Eight come often?"

The maid nodded blankly: "Yes, often come." Aunt Eight's stomach pain is unbearable every time Kwai Shui, and she is very concerned about this disease, so she often comes to see medicine. Sometimes I watch it by myself for a while. ”

Everything is just around the corner of the air.

Although Sa Youxin couldn't go out to buy medicine, she could take out her pair of angelica slices cut into slices in the Yi Kidney Tong Meridian Soup, put it into Yao Haifeng's medicine when it was boiling, and then pick it out after boiling for a while.

It can even be simpler, scoop two spoons into your own medicine and put them into Yao Haifeng's medicine.

In this way, when you check the residue, you won't find anything unusual, and when you drink it, the taste won't change much, Yao Haifeng is not a doctor, and he can't taste it. No matter how he changed the prescription, he was ingesting harmful ingredients every day.

When Ye Caitang came to find Sa Youxin again, it was completely different.

Sa sat in the room with a blank face, and when he saw Ye Caitang, he was even a little happy.

She still likes this young girl, although she is here to investigate the case, but she is polite and kind-hearted.
