According to the records just made, Zou Yu found that the best ratio was seven points to two points, which was the most suitable. As for the formula, peppermint, camphor are the main materials, like honeysuckle, wormwood, these are all excipients.

When applied to the hands, the cool feeling is not much different from that of later generations, and as for the mosquito repellent effect, you have to let people feel it to know.

As for how to feel, this is very easy to do, let the guards smear some and find a corner to squat for a while.

"This is called toilet water, which can not only prevent mosquito bites, but also relieve itching. Zou Yu introduced with satisfaction.

Although his cottage toilet water, the treatment effect is definitely not as good as that of later generations, after all, he only knows these materials, but this should be enough, and it is a big deal to apply it diligently.

"Wow! Are you sure? Hei Sumei is much more lively, listening to what Zou Yu said, she stretched out her fingers in amazement, dipped a little, and smeared it on the back of her hand.

"Really! It's cool and quiet, and it's quite fragrant. Raising the back of her hand and putting it under her nose to sniff, Hei Sumei continued in surprise.

"Give this a try!" Zou Yu opened the last two altars and said with a gentle smile to Bai Suhua. After saying that, I smeared a little bit on the back of her hand.

"It smells so good! Gardenia flavor. Bai Suhua's neck stretched slightly, sniffed lightly, her eyes lit up, and she smiled.

"It's made especially for you, and there's a sandalwood smell here." Zou Yu introduced.

"Hmm!" Bai Suhua was full of emotion and nodded gently.

"I'll leave it to you here, these two jars are called perfumes, experiment by yourself, how to make the fragrance last longer, you can also experiment with other flowers and plants, as for the flower water, you can ask the imperial doctor to see if you can add something simple and easy to pick." Zou Yu said to Yang Yu.

"Don't worry! I'll definitely do it, but what's the use of this perfume with all this effort, is it just to replace the sachet? Yang Yu first nodded, and then asked puzzledly.

"You're still young, you don't understand, remember to go back and bring some to your mother." Zou Yu said with a smile.

Perfume, which in later generations, is a must-have item for almost all women, and the price is quite high.

"That's right! It took so much energy, just like that, it's not cost-effective, it's better to sell wine directly, this wine is so fragrant! Xi Junmai nodded in agreement with Yang Yu's point of view, and looked at the wine jar, which had just developed, and the slightly raised Adam's apple shook for a moment, and he was still swallowing saliva.

"Humph! This thing is very expensive, and it's not worth selling you! The idea of drinking less. Zou Yu pretended to be angry and glared at him and said.

"What! This altar is worth more than me! How much can it sell? Xi Junmai was not angry, but just said with a pout.

"Huh! Sell it in a small bottle, this jar must hold at least more than 200 yuan, and if you sell it, you have to sell it for 300 or 50 yuan! Zou Yu knocked lightly on the jar and estimated with a smile.

"What! It contains 200 bottles, and it also sells 350 bottles of a small bottle! How could a few people buy. Xi Junmai first stared at him, said in disbelief, and then shook his head to show disbelief.

"Humph! If you put it in a delicate bottle! It can be sold for 100 guan and one chan! Woman! For this, I am very willing. You're still young and don't understand. Zou Yu said disdainfully.

"As long as you have money, you won't let it go if you encounter it, especially those from big families." Bai Suhua explained to him with a smile.

As a woman, of course she knows, everyone is definitely willing to make themselves fragrant. Although the sachet is good, it doesn't taste as good.

Generally speaking, the sachet is single, and it is the smell that you like, but after all, it is only a little big, and the taste must be very small, so some big families, before going out, will aromatherapy clothes, just to make the taste stronger and more lasting.

It's just that aromatherapy clothes are more cumbersome, and they can't be managed for long, but this perfume is different, the smell is strong but not gaudy, simple and convenient, and you can apply a little to yourself at any time. It's perfect for applying temporarily when you're out and about or when you need it.

"Hmmm! If you can afford it, you will definitely be willing to buy it. Yang Yu thought about the palace, his clothes were scented every day, and there were sachets he carried with him, and he nodded approvingly.

"Get it right! In the future, it will not only be sold to Guanzhong, Jiangnan, but also to the Western Regions! Zou Yu encouraged Yang Yu.

"Hmm!" Yang Yu nodded vigorously, he felt that life had suddenly become less boring, and he seemed to have found a direction to struggle.

Zou Yu didn't care too much about perfume and toilet water, after all, this thing was not small, only rich people bought it, and he didn't think about selling it under his own rule first, so he just took the lead in getting it out, and then handed it over to Yang Yu to improve, after all, there wasn't much he could do.

Relatively speaking, he preferred another discovery, and he stumbled upon a fireproof cloth that was used to isolate the treasury of the palace. After a closer look, I found that it was actually asbestos.

It is surprising that in this era, someone actually made cloth from asbestos, which is an incredible thing.

How asbestos is used, Zou Yu is not clear, but he knows that a kind of ore associated with asbestos has a lot of effect, which is also what he used to watch girls do makeup, inadvertently fiddle with cosmetics, and watch the composition of cosmetic materials on the bottle, so as to remember and check it.

Talc! This is the associated mineral of asbestos, which is used the most, is a variety of cosmetics, pediatric talcum powder!

Zou Yu asked people to find it in Liaodong according to the clues of asbestos, and let people carefully grind it into powder and twist it gently, which was really smooth.

For Zou Yu, talcum powder has three functions, the first is to stop bleeding! Talcum powder for traumatic hemostasis, the effect is good, although not as good as the famous notoginseng, but it is cheaper, compared to grabbing a handful of plant ash, soil, the effect is a hundred times stronger. The key is also that it is convenient, cheap, and large. On the battlefield, the wounded soldiers are not one or two, where there are so many doctors to treat, they are all wrapped with some medicinal herbs casually, as for those who lack arms and legs, they are basically dead, and a hundred don't want to survive a single one.

In this case, the doctor will only use a cloth belt, and the dead help people entangle, compress the blood vessels, and then bandage them, such a large wound area, there is no special hemostatic drug to stop the bleeding, whether you can survive or not, it all depends on the will of God.

Therefore, after a big battle, only half of the people killed on the spot, the other half, and thirty percent died because they couldn't stop the bleeding, and the rest were wound infections.
