Gu Yunjiao continued: "There are many people in the world who make fake medicines for silver, and the valuable ones such as ginseng notoginseng are slightly cheaper medicines, and there are also fake ones. ”

"Therefore, we must first be careful when recognizing medicines, because fake drugs sold to patients not only have no effect, but some are even harmful."

Ah Tie nodded, "I must be careful." ”

Gu Yunjiao smiled and said, "If you are careful, you must also be patient." ”

"For example, if I tell you about the preparation of medicinal herbs, you will know how troublesome it is."

She paused, "There is a medicine called Renzhong Huang, and people in the world have many misunderstandings about this medicine, thinking that this thing is too dirty. ”

"Some people even see the yellow color and think it's human excrement, which is not right."

"This person is yellow, in fact, licorice is powdered, and then poured into a bamboo tube that scrapes the skin, plugged it with yellow paper, and then sealed it with rosin."

"Then on the day of the beginning of winter, soak the bamboo tube in the water manure pit."

Ah Tie has treated with pig feces, but he doesn't dislike these and urine, and listens very carefully.

Liu Er couldn't help but interject in front, "Put it in the manure pit, isn't it dirty?" This medicine has to be eaten! ”

Gu Yunjiao smiled, "There is a membrane in that bamboo, you know this." ”

"That dirty stuff can't get through."

In fact, it is a bacterium and a virus, and the molecules are relatively large and cannot penetrate this membrane.

The rest of the small molecule organic matter, inorganic salts, can penetrate the membrane and act with the drug.

Gu Yunjiao continued: "After soaking in, on the day of the beginning of spring, take out the bamboo tube, and after taking it out, put the bamboo tube into the east flowing water and float it." ”

Ah Tie asked, "What is the East Flowing Water?" ”

Gu Yunjiao smiled, "The great rivers of our Great Chu Dynasty all flow eastward into the sea, and this river is also flowing eastward. ”

Ah Tie suddenly realized, "That is, put the bamboo tube into the river water and float." ”

Gu Yunjiao nodded, "Generally, find those big boats that don't move, hang them on the side of the ship, and then fish them out after two months." ”

"After this step, the bad smell is completely dissipated, and the toxicity and heat are also removed."

"Therefore, if you really bleach, you won't have a smell."

Liu Er in front of him was stunned when he heard it, "My God, this flavor medicine is so troublesome to make!" ”

Gu Yunjiao smiled, "It's not over yet, put these bamboo tubes on the roof for a long time, and after they are dried, then split the bamboo tubes, at this time, the licorice powder in them will be glued together into the shape of a bamboo tube, which is a cylinder, take out this thing, dry it, and then it can be used for medicine." ”

After Gu Yunjiao finished speaking, she had the intention to take a test for Ah Tie, "Do you remember the steps I just said?" ”

Ah Tie thought for a moment and began to repeat it.

Gu Yunjiao listened carefully, although he didn't do it word for word, but he memorized all the steps, and there were no mistakes, which was rare, indicating that he really listened.

She laughed and gave Ah Tie a thumbs up.

Ah Tie asked curiously, "What is the use of this medicine?" ”

Gu Yunjiao said: "It can clear heat and cool blood, and detoxify fire." ”

Ah Tie's eyes lit up, "Is it possible to use a sore like this on my head?" ”

Gu Yunjiao nodded, "Smart, it can indeed be used." ”

"Renzhong Huang can cure plague, erysipelas, and sores, but this also involves the formula, not just a medicine, this has to be learned slowly."

Gu Yunjiao said again: "You learn medicine first, if you have talent, I will teach you to see a doctor in the future." ”
