According to historical records, one of the medicinal materials for preparing pointed medicine is keel, without which it is difficult to exert its curative effect. After discovering the efficacy of this medicine, people all over the world rushed to buy this medicine in case of injury. In addition, knife tip medicine was very affordable and became a necessary medicine for people at that time. As a result, a large number of tip drugs were produced, which made the keel consume too much, the supply was insufficient, and the resources were exhausted, so it was natural that no drugs could be made.
Keel is an important load-bearing object in Oracle Bone Inscriptions, and mining is prohibited by the state. An important source of the keel for preparing pointed medicine in Qing dynasty was the keel of Anyang, Henan Province, but it was engraved with words. After textual research, it was discovered that it was originally written in the civilized Shang Dynasty. This discovery set off the climax of Oracle Bone Inscriptions research in China.
Because it is more profitable to sell the keel to traffickers in Oracle bone inscriptions, people have given up using the keel as a sharp medicine, and this idea continued until liberation. After the founding of New China, scientific research flourished. Many experts realized the importance of Oracle Bone Inscriptions to the study of Shang Dynasty history, and asked the state to prohibit the exploitation of keel by law. Since then, the keel can no longer be mined, nor can it be used to make sharp medicine. So I haven't seen it since liberation.
After the founding of New China, the national medicine industry developed rapidly. With the continuous research of professional researchers, more new hemostatic drugs with remarkable curative effect and low price have appeared. Sharp drugs are essentially hemostatic drugs, and the emergence of new drugs makes people gradually abandon the traditional sharp drugs. After losing the market, knife-tip medicine slowly withdrew from the historical stage and disappeared.
To sum up, the disappearance of knife-tip medicine is the result of historical development, not the loss of traditional culture.
