Gu Long 's novel world has four decades. The first decade is the world of Shen Lang , the second decade is the world of Li Xunhuan , the third decade comes to Li Xunhuan's apprentice Ye Kai , and the fourth decade is the world of Shen Lang's only apprentice Gongziyu. This can be said that there are talents in the country and have led the way for hundreds of years.

The same is true for the Chinese medicine world. As you walk, some drugs that have been used frequently will gradually disappear from this "王子子". The , Xueyutan we talked to you today is one of them. Speaking of Xueyu Carbon, in addition to those who have studied traditional Chinese medicine, they also use it as a topic of conversation after dinner, ordinary people have long been extremely unfamiliar with this drug. However, among our grandfathers, blood carbon is one of the Chinese medicines used by the people every day. Oral administration can promote blood circulation and remove blood stasis and , which can promote diuresis and promote bleeding, while external use can stop bleeding. Today, I will revisit this traditional Chinese medicine that is rarely used in today's society. Personally, I believe that the fading of Xueyu Carbon from the "jianghu" of traditional Chinese medicine is not because it has no therapeutic effect, but because we have better choices with the progress of society.

Blood Carbon is also known as hair, messy hair, gray hair, hair, and gray hair. Compendium of Materia Medica says: "The hair is the residual blood." Chinese medicine made with calcined hair is called blood carbon. "Medical Heart-to-Chinese Cong and Western Records" records: "There is blood left, and if it is not calcined, its quality will not be transformed. Therefore, it must be calcined into carbon and then used as medicine. Its properties can remove blood stasis and produce new blood, which is similar to Panax notoginseng , so it is good at treating vomiting blood and epistaxis." " Shennong Bencao Jing " also says, ": Blood left carbon is responsible for five ginger, and the barrier is blocked, which can promote urinary waterways, cure epilepsy in children, and adults' spasms."

I have always remembered a question asked by the Chinese medicine teacher when I was in school. If we are trauma in the wilderness and need to stop bleeding, and we happen to have no traditional hemostatic drugs, can we quickly find emergency medicines that can be used to stop bleeding? Just when we were all looking at each other, the teacher touched our hair and said, "Actually, the medicine is on our own heads. Clean the hair and burn it to ashes on fire, which becomes blood carbon. This is a good medicine for astringent and stopping bleeding." This is also the first time I heard that hair is actually a medicine and has the effect of stopping bleeding. However, this is just the roughest way to make blood carbon. The method of making real blood carbon is not as simple as we imagined. Generally, you need to collect a large amount of hair from healthy people, first pick out impurities, repeatedly wash them with alkaline water, then wash them again with clean water, then take them out and dry them, put them in a calcined medicinal pot, fill them with compaction, cover them, then seal them with yellow mud, and press the heavy objects on them. Finally, heat it on low heat, calcinate for about 4 to 5 hours and stop fire. The next day, wait until the pot cools down before it can be taken out. Then cut into small pieces of 1 to 1.5 cm to serve as medicine. The roughly prepared blood carbon can be applied externally to stop bleeding, while the finely calcined blood carbon can also be taken, which also has the effect of removing blood stasis and stopping bleeding, diuresis and promoting irritation.

So, why is such a useful Chinese medicine not commonly used now? Is this a product of ancient superstition or is it that the blood-residing carbon has no function recorded in the book? In fact, none of them are, but the changes in the times have given us more and better choices. In the past, many vendors would go from street to street to buy our cut hair, and then sell our hair to traditional Chinese medicine stores to make blood carbon. But today, there are no more vendors who buy hair and sell it to pharmacies for medicine. And now, we also have more drugs and means to bandage and stop bleeding, and there is no need to use blood carbon to stop bleeding. The same is true for internal treatment. With the research and development of various Chinese patent medicines that promote blood circulation and remove blood stasis, diuresis and irritation, blood carbon also slowly retreated from the "jianghu" of traditional Chinese medicine.

The retreat of blood carbon is actually a good thing. But we should not look at this drug that has played an important role in the long river of history with doubts and jokes. This type of drug should not be labeled as feudal superstition and backward, thereby criticizing traditional Chinese medicine. Although they are not used frequently now, they should not slowly disappear from our memories.Perhaps at some point in the future, it will continue to help us more in other ways.
