Fang Zhai more than ten acres [system]

Didn't expect this man to have some narcissistic traits?

Yu Rong muttered to himself, but did not probe into the other party's implication, his mind was still on the saffron and golden bell seeds.

Golden bell and crocus have strong adaptability, and theoretically they can be planted in both north and south.

Therefore, he thought about planting at home at the first time, and then figured out that the number of seeds was still too small.

I have no experience in planting before, even if I have the encyclopedia of cultivating medicinal plants, it is just a theoretical school... After all his fuss, if the cultivation fails, the seeds will be wasted.

Forget about Jinlingzi, maybe you can buy it from Xihu or Nanfan merchants in the future.

Crocuses are not the same.

If this thing is not pollinated artificially, it is almost impossible to produce seeds. I am afraid that these seeds can be obtained by various chances and coincidences, and it is extremely difficult-Nie Xinzhi was able to buy it, which can be described as "a blind cat meets a dead mouse".

Thinking about it again, even in modern times, saffron is still a very expensive and precious medicinal material, and it must be planted on a large scale, which is far from easy.

The most important thing is that, as a medicinal material, saffron must be taken from the pistil stigma and used as medicine after drying, which means that its harvesting is extremely troublesome. Compared with many other medicinal materials, its yield per mu will obviously be very low.

One can imagine the time and effort required to "prosper" this new species and introduce it into Minchao's medical applications.

After thinking about it, thinking that Nie Xin has countless capable people, Yu Rong suggested: "It's better to leave these seeds to your people to cultivate, and it's better to plant them in coastal areas with mild climate."

Nie Xinzhi didn't respond immediately, but only asked, "Do you not like it?"

Yu Rong explained: "I like it, that's why I asked the people under you to help plant it. I'm afraid I'll be planted to death... It's just such a little seed, don't waste it for nothing."

It is impossible for him to devote too much energy to the cultivation of medicinal materials. Even if he feeds himself, he will probably only grow two or three plants. If he wants to use them as medicine, there will be enough for them. I am afraid that they will only be used purely for ornamental purposes.

Nie Xinzhi didn't ask any more questions, but nodded slightly: "Okay." He changed his tone and added, "If necessary, I will contact the Xihu people later."

Yu Rong smiled and nodded, not rejecting the man's kindness.

Maybe, can you trade more seeds that Min Dynasty doesn't have from foreign merchants?

The exchange of species is inevitable in the development of history.

Instead, he suddenly remembered something.

In countless modern court dramas, the "good partners" of saffron and musk play an indispensable role in almost every drama, and they can be called the "trigger" of contradictions.

Can't help but feel a little embarrassed.

I feel that I, who intends to introduce saffron, seem to have done some great pioneering work?

The medicinal value of saffron is indeed high, and it has a wide range of indications, but it does... have the effect of stimulating the uterus, especially for the pregnant uterus, which is very sensitive.

"What's wrong?"

Yu Rong regained consciousness instantly, and shook his head: "It's okay, I'm a little sleepy."

Forget it, he still shouldn't think too much... Crocus is not guilty, but the evil is in the hearts of some people.

Nie Xinzhi suddenly packed up the books.

Seeing this, Yu Rong asked doubtfully, "Are you done?"

"It's late at night, it's time to rest."

"It was time to sleep..."

The lights went out, and the human voice disappeared.

Grain Rain seeds fell to the ground, and in a blink of an eye, it was time for awn crops to be planted.

Farmers are busy competing for time or harvesting or sowing.

Yu Rong was also busy, so he didn't mention the matter in the field. Because of the feedback from Lin Sange, he is now starting to develop new products again.

Someone asked Lin Sange if he had any mosquito repellent that was easy to use and effective.

Since various herbs with insect repelling effects were planted in the front and back of his own yard, Yu Rong almost forgot that there are still such disturbing things as flies and mosquitoes in summer. Shen Yin agreed, saying that he would develop a batch of "mosquito coils".

In this era, ordinary people repel mosquitoes in summer, and directly find some plants with insect repellent effects such as wormwood for fumigation.It's just that there are too many mosquitoes, one batch will be smoked to death, and then a new batch will come. Burning wormwood is far less convenient than mosquito coils.

Of course, the "mosquito coil" that Yu Rong wants to develop is completely different from modern mosquito coils.

Still use medicinal materials as raw materials to make pure natural mosquito-repellent incense.

Unlike the cumbersome preparation of incense sticks, the production process of mosquito coils is much simpler.

Considering the different needs of customers from different classes, Yu Rong also differentiated the "grades" of mosquito coils this time, just like the toothpaste and shampoo that he produced before.

The grades are different, and the raw medicinal materials selected are not the same.

But in fact, the mosquito repellent effect of various grades of mosquito repellent incense is almost the same.

However, in the "high-end" mosquito-repellent incense, some sandalwood wood shavings, and even precious spices such as agarwood shavings are added.

Regardless of the grade of mosquito-repellent incense, the main raw material used is actually wormwood.

Then add a little mint leaves, turtle shell or atractylodes and other medicines that have the effect of repelling insects, after crushing, grind them into powder.

The mugwort leaf oil extracted by the reflux extraction method is mixed with a small amount of turpentine or paraffin, and mixed with powdered medicine to form a mosquito-repellent incense.

You only need one or two spoonfuls of mosquito-repellent incense, and it can continue to burn all night after burning. Needless to say, the effect of mosquito repellent, the smoke emitted during burning is much smaller than that of directly burning wormwood, so it will not choke while repelling mosquitoes. own.

In addition, if you use mosquito coils as incense, it is not a bad idea.

Compared with modern mosquito-repellent incense, this kind of natural mosquito-repellent incense not only can repel mosquitoes, but also has a "health-preserving" effect.

Because the selected medicine has the effect of expelling wind and cold, when burning, a little medicine gas enters the human body, which can prevent exogenous diseases to a certain extent.

Except for the extraction of mugwort leaf oil, which took some effort, the whole process of making mosquito coils is quite trouble-free.

With the help of his apprentices, Yu Rong made a mosquito-repellent incense with three ingredients without much effort.

First, a carpenter was asked to customize hundreds of small wooden boxes with good airtight effects.

Each mosquito coil can hold at least a hundred boxes, and each box can be used for five to seven days.

Without delay, Shi Ni was sent directly to drive the repackaged mosquito coils to Lin Sange's residence in Yanzhou.

What comes next is the real trouble.

Same goes for mosquitoes.

It is a very common thing to be bitten by mosquitoes in summer.

However, the mosquitoes in Min country are generally somewhat "poisonous". If you accidentally get bitten, it's a trivial matter to get a "bag". The key is that it often itch for several days. It was so itchy and painful that it was hard to scratch my heart and liver.

If you go to see a doctor or get medicine from a pharmacy because of mosquito bites, it’s not cost-effective, and it’s especially troublesome to make a fuss about it.

I don't care about it, but sometimes I can't stand it.

Really disturbing.

Then someone came to Lin Sange.

Lin Sange is now quite a well-known businessman in Yanzhou. Many people know that he sells some weird and useful things. In addition to the influence of Kuang Wanchuntang, the reputation of "Little Doctor Yu" has spread more and more. The farther away... some people begged to buy mosquito coils, and some people hoped that "Little Doctor Yu" would give up some ointment that could be applied to relieve itching.

After Lin Sange conveyed these messages, Yu Rong immediately thought of two summer artifacts.

—— Essential Oils and Refreshing Oils.

Essential oils are liquid and extremely volatile, so storage is a big problem.

Naturally, the focus is on cooling oil. Although cooling oil is also easy to volatilize, it is relatively convenient to store and carry.

Yet the preparation procedure of cooling oil is extremely cumbersome.It was also Yu Rong who became interested and had some thoughts in his heart, otherwise he would not have wasted all this time and energy.

just a little...

The main ingredients of cooling oil, Vaseline and ammonia are not as convenient to obtain as in modern times. Without these two, it will take more effort to prepare smoothly.

Moreover, other ingredients such as peppermint, camphor, clove, etc., all need to be extracted from the oil, which is time-consuming and labor-intensive.

Yu Rong didn't intend to embarrass herself.

For example, petroleum jelly, even in this era, oil has been discovered, and it is easy to find something to do by refining it by yourself.

It is better to directly use the prescription of the predecessor of qing liang you, "wan jin yao", and then refer to the systematic pharmacopoeia to make slight improvements.

Cloves, cinnamon and other eight-flavored medicinal materials extract oil, add ground menthol and camphor, take paraffin wax, ozokerite, etc., heat and melt, then pour in the mixed liquid of various medicinal materials, stir the filtrate while it is hot, and wait for it to cool. Into light yellow paste.

The cooling oil is thus complete.

To put it simply, due to the lack of specific ingredient ratios in the prescriptions he knew, Yu Rong failed several times, and after half a month of busy work, he finally made a qualified ointment with one kilogram of ingredients.

He tried it himself, and the effect of the medicine was not much different from that of real cooling oil, and the sticky feel was relatively inferior.Seeing that the weather is getting hotter and hotter, it can only be stored for about a month or even 20 days, and the properties of the medicine will deteriorate after the expiration date.

Regarding this, Yu Rong didn't force it, limited by his ability and production conditions, being able to make such a cool oil at present is already his best level.

Anyway, I didn't intend to expect to make much money by selling cooling oil.

——Even if you make money, it is simply not worth the hours and effort spent in it.

The reason why Yu Rong put in so much effort to prepare cooling oil was only for Nie Xinzhi.

That man is not like him, he "squats at home" all day long, and always has to go out to perform official duties every now and then.

What exactly he was busy with, Yu Rong had no intention of inquiring and was not curious.However, when the man came back recently, there were many marks of mosquito bites on his body.Then I found out that that guy has a physique that attracts mosquitoes very much. Even if there are so few mosquitoes in his house that he doesn't need mosquito coils, he will always be bitten several times a day.

Nie Xinzhi didn't care about this at all. Obviously, he has a very strong endurance. Not only is he rarely scratched by mosquito bites, but he is usually not interested in applying ointment unless necessary.

But Yu Rong couldn't get used to it, or felt a little bit distressed, so he decided to finally develop the cooling oil.

Cooling oil can not only relieve itching, detoxify, and treat mosquito bites, but also cool and dissipate heat. It is quite effective against colds and heatstroke. It is especially suitable for people like Nie Xinzhi who often travel outside in hot weather.

"What is this?"

Yu Rong was holding a bottle of balm oil, and was playing with it boredly, when suddenly he was surrounded by someone from behind.

Accustomed to such "surprise raids", he was no longer frightened by someone's disappearance, so he didn't look back, and said calmly, "Guess?"

Nie Xinzhi was silent, and after a while, he suddenly hugged him horizontally.

Yu Rong: "..."

This guy looks serious and serious, why is he thinking about colorful things in his mind.

Eh, wait-

Blessed to the soul.

Inexplicably, Yu Rong met Nie Xinzhi's brain circuit, and suddenly exhaled softly: "Brother wait a moment!"

His tone was urgent and quick——

"Cool oil is different from lubricating ointment. It is not used for... sexual intercourse."

That thing, if it is really applied on certain body parts, it may kill people! !
