    After listening for a long time, Lu Qingtang, who had not interrupted, joked, "Don't just say nice things, use the actual benefits. No matter how you make this recipe, you can't lose a hundred taels of silver."

    Hu Mingniang rolled her eyes at him, "I'm not a copper-smelling businessman like you. Don't ask for money for everything. Ah Jiu, I'll give you the dividends."

    Lin Xuan thought for a long time and did not refuse, "Then when I develop the cosmeceutical, I will give it to my sister first."

    Of course, this also includes prescriptions.

    "That's a good feeling."

    Lin Xuanjiu suggested that she first find someone to make distillation and extraction equipment, and after producing the essential oil, compare it with the existing essential oil in Hu Mingniang¡¯s hands before discussing the next step.

    Completely put the risk on your own side.

    Of course Hu Mingniang had no objection, and she generously said that she would provide the fragrant flowers.  It can not only control the quality of essential oil raw materials, but also save Lin Xuanjiu the trouble of buying everywhere.

    After the discussion was over, the two of them got a lot closer. They walked arm in arm to Fu Yun Lai and had a big meal.

    When they arrived at the dinner restaurant, Lu Qingtang got busy again. After staying with him for a while, he went to work on his own.

    Lin Xuanjiu asked Hu Mingniang many questions in detail about making balm.

    Except for the formula, Hu Mingniang has no reservations about any not-so-confidential issues.

    The focus of ancient balms is on fragrance, followed by skin care.

    Lin Xuanjiu hopes to improve the paste content of the balm without affecting the original fragrance, so that it can have the effect of a modern facial cream.

    There are many cosmeceutical brands in modern times.

    After saying goodbye to Hu Mingniang, Lin Xuanjiu had a lot more things to do.

    But she is more motivated than before and less timid. She can display her talents without any scruples.

    Xie Dongxiang valued her so much. Even if she had more special features that were far beyond ordinary people, she would not attract covetous attention. There was really no need for her to hide her.

    It was already late when Lin Xuanjiu arrived home, but the fragrant flowers she brought back could not wait for the night. In such a cold day, even if they were put into wooden boxes to keep warm, they would easily freeze.

    The fragrant flower provided by Hu Mingniang is wintersweet.

    The yield of plum blossoms is already low, and fragrant varieties are likely to be more expensive.

    We can only work overnight.

    She commandeered a large casserole at home, sawed holes in the pot lid to allow steam to pass through, and used bamboo with the inner core hollowed out as a simple conduit.

    After working for most of the night, I got more than half a can of plum blossom hydrosol, but only a small bottle of essential oil.

    She brought the essential oil to Hu Mingniang, the glamorous powder shop owner, without concealing her surprise and excitement.

    "So you can squeeze so many fragrant flowers?"

    With her original skills, it would be great to be able to extract one-third of this.

    So the cooperation between Lin Xuanjiu and Ningxiang Pavilion was finalized, and he would also receive a 10% dividend.

    In the next few days, Lin Xuan was so busy that he didn't even have time to take a sip of water. When he got home every night, he was so tired that he almost fell asleep.

    Xie Dongxiang treats her well, so she will naturally repay him.

    " This kind of freeing up funds for her to develop, she must not be limited to the field of cosmeceuticals. Compared with medicated diet, cosmeceuticals, and the research results in the direction of surgery, Xie Dongxiang will be more helpful.

    There is no way to fight without getting injured, and when injured, she comes in handy.

    In fact, as early as when he picked up the seriously injured Feng Qingfeng, Lin Xuanjiu thought that it would be great if there were conditions for surgery.

    ????????????????????????????????????????????????????????????????????????????????????????????????????: ? or?she has a plug-in like an air needle? It would be a real loss if she doesn¡¯t practice surgery.

    In this era, there were already rudimentary surgeries, and the procedures were similar to those in modern times, but the difference in conditions was not as big as usual.

    The first point is that a sterile environment cannot be achieved, so intraoperative and postoperative bacteriostasis must be taken into consideration.

    The penicillium that is currently being cultured experimentally is an important part of extracting penicillin. Penicillin is a major discovery that has changed the entire medical world.

    With this antibacterial antibiotic, some injuries and diseases are no longer incurable and terminal illnesses.

    With several more tanks for cultivating Penicillium, the experiment will definitely have a failure rate. With more materials, the experiment can continue without interruption even if it fails.

    In addition, she also found the best blacksmith in Xiangshui County, paid a high price, and asked an older and experienced man to make scalpels and needles for herself.

    The first complete set of modern surgical tools of our era.

      The cost is extremely expensive. It is made of pig iron and is completely plated with silver.

    There are too many impurities in iron and it is very easy to be corroded.  In order to minimize infection, the cutting edge must at least be silver-plated.

    As for whether the sharpness will be reduced, we can only slowly find ways to solve it.

    After making surgical supplies, Lin Xuanjiu also thought about rehydration. She used to have fun and read a research paper on coconut water replacing glucose injection.

    In extreme cases, a whole fresh coconut can be used as a hanging bottle.

    The inside of coconut is a sealed system, which is theoretically sterile.

    The only troublesome part is the pressure and the high potassium content, but compared with saving lives, this hazard is completely acceptable.

    After gathering the knives, Lin Xuanjiu tried his hand at small animals. He hadn¡¯t used a knife in a few days, so his skills were quite rusty.

    By the time she extracts the penicillin, it will basically be ready for surgery.

    But penicillin cultivation can¡¯t be done in a hurry.

    Seven days have passed, and it¡¯s time to purify the penicillin culture solution.

    Conditions were still limited and there was no centrifuge, so Lin Xuanjiu could only choose a simple and crude separation method.

    The method is also simple. Choose a clean clay pot, transfer the coarsely filtered culture solution into it, and then add three times the amount of rapeseed oil as the culture solution.

    Then, stir thoroughly until the layers are separated.

    Rapeseed oil is used to dissolve fat-soluble substances, while penicillin is water-soluble.

    After removing the grease, she added activated carbon to the water at the bottom of the tank It was also a crude product she burned herself. Before figuring out whether it was good or not, she could only solve the problem by herself.

    Activated carbon will absorb the water in which Penicillium is dissolved.

    Use distilled water to clean these charcoals, add acidic vinegar water, and finally use alkaline seaweed juice to clean them.

    Divide the resulting liquid into multiple portions of 100cc, transfer to a petri dish, and continue culturing with culture medium.  I thought about observing, so the crystal petri dish finally came in handy.

    What¡¯s more troublesome is that the test for penicillin is using Staphylococcus aureus, and Lin Xuanjiu can only extract it from urine. Due to the conditions, there is no other way.

    A few days later, Lin Xuanjiu almost cried with joy when he discovered that penicillin was only growing in a circle around Glucococcus in the crystal petri dish!

    It is simply too difficult to engage in scientific research without any conditions.

    Homemade penicillin, which was so crude that almost every link had safety risks, was a great breakthrough, and it also solved the big problem in Lin Xuanjiu's heart.

    After holding back in the laboratory for several days, the disgraced Lin Xuanjiu finally had the thought to go out for a walk.  (Remember the website address: www.hlnovel.com
