According to the records just now, Zou Yu found that the best ratio is 7 o'clock to 2 o'clock, which is the most suitable. As for the formula, mint and camphor trees are the main materials, such as honeysuckle and mugwort, these are auxiliary materials.

When applied to your hands, the cool feeling is not much different from those in later generations. As for the mosquito repellent effect, it is necessary to make people feel it before they know it.

As for how to feel it, this is easy to do. Ask the guards to apply some of it, and you will know it after finding a corner and squatting for a while.

"This is called flower dew water. It not only prevents mosquito bites, but also relieves itching. If you have been bitten by mosquitoes, just apply it a little." Zou Yu introduced with satisfaction.

Although the therapeutic effect of his copycat flower dew water is definitely not as good as that of later generations, after all, he only knows these materials, but this should be enough. At worst, he can apply it more diligently.

"Wow! Really?" Mesomei was much more lively. After hearing Zou Yu's words, she exclaimed and stretched out her fingers, dipped them a little, and applied them to the back of her hand.

"It's really! It's cool and fragrant." He raised the back of his hand and put it under his nose to smell it. Mesomei continued in surprise.

"Try this!" Zou Yu opened the last two jars and said with a gentle smile to Bai Suhua. After that, he applied a little to her on the back of her hand.

"It smells so fragrant! The smell of gardenia." Bai Suhua stretched her neck slightly, sniffed it gently, her eyes lit up, and she smiled.

"This is made specifically for you, there is also a scent of sandalwood here." Zou Yu introduced.

"Yes!" Bai Suhua was moved and nodded gently.

"I'll leave it to you here. These two jars are called perfume. Experiment by yourself. How to make the fragrance last longer? You can also use other flowers and plants to experiment. As for flower dew, you can ask the imperial doctor? See if you can add some simple things? It is easy to pick." Zou Yu reminded Yang You.

"Don't worry! I will definitely make it well, but I'll spend so much effort? What's the use of this perfume? Is it just to replace the sachet?" Yang You nodded first, then asked in confusion.

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

Perfume is a must-have item in later generations? Almost all women? The price is quite high.

"Yes! I spent so much energy, just a little bit, isn't it cost-effective? Why not sell wine directly? This wine is so fragrant!" Xi Junmai nodded and agreed with Yang You's point of view. He looked at the wine jar. The Adam's apple that had just developed and slightly raised was shaking. He was still swallowing his saliva.

"Hmph! This thing is very expensive? It's not worth the jar if you sell it! You're not going to be so good! You're not going to make a drink." Zou Yu said to him with annoyance.

"What! Just this jar is more valuable than me! How much can it be sold?" Xi Junmai was not angry. She just said with a pout.

"Haha! Use a small bottle to sell. This jar? At least two hundred stews? If you sell it, you have to sell it? You have to thirty or fifty stews per stew!" Zou Yu tapped the jar lightly and estimated with a smile.

"What! I put two hundred bottles, and I also sold thirty or fifty knots per small bottle! How could there be a few people buying it?" Xi Junmai first glared at the eyes and said in disbelief, then shook his head and expressed his disbelief.

"Hmph! If you pack it in a delicate bottle, you can sell it for 100% of a year! Women! I am very willing to do it for this. You are still young and don't understand." Zou Yu said contemptuously.

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

As a woman, she certainly knew that everyone would definitely be willing to make herself fragrant. Although the sachet is good, it tastes less good.

Generally speaking, sachets are filled with a single flavor, which is the taste they like, but after all, they are only a little big, and the taste must be very small. Therefore, some big families will scent their clothes before going out to make the taste stronger and longer lasting.

But aromatherapy clothes are quite complicated and can't take long, but this perfume is different. It tastes strong but not gorgeous, simple and convenient, and you can apply it a little at any time. You can apply it temporarily when you go out or need it.

"Well! If you can afford it, you will definitely be willing to buy it." Yang You thought about the palace that there were people incense his clothes every day and the sachets he carried with him. He nodded in agreement.

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

"Yeah!" Yang You nodded vigorously. He felt that life suddenly became less boring, and seemed to have found the direction of struggle.

Zou Yu didn't care much about perfume and flower dew. After all, this thing is quite limited and only rich people buy it. He didn't think about selling it under his own rule first, so he just took the lead in making it out and then handed it over to Yang You to improve it. After all, there are not many things that he can do.

Relatively speaking, he prefers another discovery. He accidentally discovered that there was a fire-proof cloth used to isolate the treasure house of the palace. After careful reading, he found that it was actually asbestos.

What is surprising is how incredible it is that in this era, people actually made cloth with asbestos.

Zou Yu didn't know how to use asbestos, but he knew that a kind of ore that was accompanied by asbestos had a great effect. This was also what he used to see girls wearing makeup, accidentally fiddling with cosmetics, and watching the cosmetic materials on the bottle, so he remembered and checked it.

Talc! This is the companion ore of asbestos, and is used as the most, which is various cosmetics and children's talcum powder!

Zou Yu found it in Liaodong based on clues of asbestos. He asked people to grind it into powder carefully and twist it gently, which was indeed extremely smooth.

For Zou Yu, talc powder has three functions. The first is to stop bleeding! Talc powder has good effect on trauma and bleeding. Although it is not as good as the famous Panax notoginseng, it is better than a handful of wood ash and soil. The key is that it is convenient, cheap, and large in quantity. On the battlefield, there are not only one or two wounded soldiers, but there are so many doctors to treat them. They just use some medicinal materials to wrap them up. As for those who lack arms and legs, they are basically dead, and no one can survive one hundred.

In this case, the doctor will only use a cloth belt to tightly help people wrap around, press the blood vessels, and then bandage them up. With such a large area of ​​trauma, there is no special hemostatic medicine to stop bleeding. Whether it can survive depends entirely on God's will.

Therefore, after a big battle, only half of the people who died on the spot were half, and the other half, 30% died from unstoppable blood, and the rest were wounds infected.
