"Swordthistle is slightly toxic, and we are going to dispose of it now. ”

Jia Yi dealt with the sword thistle orchid and explained to the fire fox at the same time.

Jia Yi has already analyzed that the toxicity of thistle orchid is actually not large, and it is more concentrated in the leaf epidermis, and it can even be eaten after peeling off the skin.

For example, some common foods are actually slightly toxic, not all foods are completely non-toxic and harmless, but most of the toxins will be eliminated during processing. For example, raw beans, fresh fungus and fresh daylily, cassava and other things are poisonous, but after processing and cooking, the toxins are very weak, and there is no effect on the human body.

But this is not good for the injured, the injured person's resistance will be weaker, and applying poisonous ointment to the wound will make it worse.

Fortunately, the toxin of the thistle orchid is not too troublesome to deal with, at least not for Jiayi.

Firefox watched Jia Yi deal with the sword thistle, stood aside from afar and said: "Although the sword thistle is relatively rare, it is not worth much, saying that this thing can treat burns and burns, but it will make people itch when applied to people, if it is only on the skin, it will be bad, it will be worse if it touches the wound, it is worse than death." ”

Thinking about the injury on his arm, he couldn't stand the itch but didn't dare to scratch it, Jia Yi shivered, and almost deformed the movements on his hands, which can indeed be regarded as torture. It is said that among the ten tortures of the Manchu Qing Dynasty, the human skin was peeled open and coated with honey for ants to bite, of course, this is more likely to be just an image processed by literature.

Only the imagination of a "scholar" could have come up with such a vicious punishment.

Jia didn't stop in his hand, and while taking off the leaves of the thistle orchid one by one, he said: "So what I have to do now is to detoxify it, the medicinal effect of the thistle orchid is not what I need the most, what I need is actually the gum inside." ”

He peeled off the skin of the leaves removed from the thistle, and put all the gelatinous flesh inside into a huge glass basin, which was not actually a laboratory utensil, but a large bowl, a fruit bowl, and sometimes Jia Yi also used this to eat noodles, a large bowl of wide noodles, one bowl was enough.

The meat is put into it and crushed, then rinsed with a large amount of water, filtered, and then separated to obtain a clear filtrate, after getting the filtrate, Jiayi put the filtrate into a coarse test tube, and then got on a simple centrifuge, after centrifugation, the gelatin in the filtrate is concentrated to the bottom, and at the bottom is some fine impurities that are not separated, and the whole solution is divided into three layers that are not obvious.

Jia Yi dropped a few drops of the indicator, and it turned purple in the top layer of the clear filtrate, he picked up the test tube and gently shook it, and the purple solution and the greenish gum in the lower part immediately showed obvious delamination. He changed a dropper and began to drip neutralizing reagent into it, shaking the test tube with each drop, and the color of the solution became lighter, and when the color of the purple solution on the upper layer disappeared, it immediately stopped.

Then he poured out the upper solution in the test tube, took out the gum in the middle, discarded the impurities at the bottom, and then dissolved again, separated, centrifuged, titrated, and repeated twice, and finally disposed of all the test tubes to get a cloud of pale green gum, the color is lighter than the first separation, if you don't look carefully, almost people think that it is colorless. This mass of gelatin is not less, the amount is about half a glass of glass, 1, 200 ml.

"Is this considered a success?" Firefox walked over and looked at the gelatin, feeling a little curious, many of Jiayi's operation steps were something she didn't understand, such as centrifugation, titration, etc., which made her feel that she really didn't learn pharmacy correctly.

It was a lot more complicated than she had imagined.

Jiayi put down the gum and began to prepare other materials: "Of course it's not finished yet, this is just to extract the gum in the thistle orchid, and remove the toxicity, it's not time to officially configure the potion." ”

Originally, when there was no thistle, he wanted to extract gum from dandelion and other plants, or extract pectin from figs, and he even had the idea of eucommia gum, but in addition to eucommia gum, the rest of the gum was too troublesome to extract, not only the extraction efficiency was very low, but the steps when extracting were more cumbersome, and eucommia gum had the worst effect.

The steps of extracting the gum of thistle orchid are already very complicated, but to extract the gum of dandelion, more and more complex processing is required, and the quantity and quality required are often not obtained.

Then he began to extract other materials, extracting the solution of hemostatic grass and white feather flower, alcohol extraction, heating, reaction, blending, mixing, stirring, etc., to obtain a real solution that can treat injuries, and finally centrifugation and activated carbon purification array to remove impurities to obtain a pure solution that can treat injuries.

Finally, he slowly heated the gel water bath, and then slowly added the liquid medicine to it, and at the same time stirred slowly and evenly counterclockwise, until the whole liquid medicine was added to the gel, and continued to maintain the heat, and continued to heat for about 30 minutes.

Then he took out the entire liquid medicine and used the magic circle to cool it rapidly, instantly reducing the temperature of the ointment to 3 or 4 degrees, and after evaporating and cooling, the ointment that originally looked a little thin showed a crystal clear light green ointment, and at the same time exuded a fresh aroma.

"Alright. Jia Yi took out the ointment and stretched out his hand to hand it out to the fire fox in the distance, while he dipped a little of his finger into his mouth and slowly savored the effect.

Firefox walked over and looked at the ointment in the bottle, the pale green gel was something he had never seen before, and he was a little curious when he looked at Jiayi: "Is this thing taken internally?"

Why else would you want to taste it? That's what she thinks.

Jia Yi hurriedly shook his head: "No, this is a pharmacist's unique method, which can distinguish the effect of the medicine through the tongue, I will taste it to see how the effect of this medicine is, after all, I have changed the main ingredient." ”

In fact, this should be regarded as Jiayi's own unique method, which is more accurate than other detection methods to identify the efficacy of the drug through the tongue. Other mages or pharmacists don't have this method, but he feels that it is not easy to win the trust of others if he is unique.

"That's how it works. Firefox asked expectantly.

Jia Yi recalled the feeling just now, and nodded slowly: "The effect is good, the effect is better than the original formula, the detoxification treatment of the sword thistle orchid is still a bit of a big loss of medicinal effect, if you improve this step, then the effect will be better, especially for injuries such as burns and scalds." ”

Jia Yi didn't say much, in the past, the gel itself did not have any medicinal effect, but now the gel also contains a part of the medicinal effect, and after combining with the main drug for treating injuries, it produces a wonderful reaction, which stimulates the medicinal effect to the maximum.

Perhaps because he was afraid that Firefox wouldn't believe it, Jia Yi took out a small jar, and then took out a piece of ointment in it, about more than 10 milliliters, and handed it to Firefox: "You go back and catch some small animals or something to try the effect, clean and remove the dirt from the wound first, and then apply the ointment, if the wound is too big and too deep, then it is best to suture it first and then apply the ointment." ”

Looking at the small bottle in his hand, which was not as high as his thumb, Firefox pouted: "You have too little for this, give more." ”

Jia Yi waved his hand: "Don't be dissatisfied, this ointment is not cheap, if I take it out and sell it, I will sell it for at least 5 silver coins, my ointment was very popular when I was in the academy." Now you should know that the sword thistle orchid I bought didn't suffer a loss. ”

For such a small bottle, the large bottle of ointment in Jia Yi's hand can at least be divided into more than 10 bottles, and even if the price of other herbs is added, it is not a small profit.

He still remembered that Firefox said that he had suffered a loss when he bought sword thistle.
