In China, there is a kind of traditional Chinese medicine called keel, which has strong medicinal value. Chinese people have “eaten” it for thousands of years. This kind of keel has been considered as the skeleton fossil of ancient larger mammals, including elephants, rhinoceros and other common animal species.
Keel is fossilized animal skeleton, so its main components are calcium carbonate, calcium phosphate and some trace elements. Since ancient times, there are numerous records about its medicinal use. However, when people found these fossilized bones, there were basically few complete bones, and these fossils have become fragments. They may really be the bones of ordinary animals, but they may also be the real “keel” – dinosaur fossils. In 2007, the discovery of Cretaceous dinosaur fossils in Henan Province began when local farmers could dig the keel. Almost everyone in the area knew that there was a medicine called keel. People used it to treat calcium deficiency such as fractures and cramps. It is said that powder could also be used to treat some scraped skin injuries. People with ingenuity had already used it to resell the keel Profit. When the experts keenly captured this information and continued to explore and study, they found that the “keel” in the local people’s mouth was actually a precious Cretaceous dinosaur fossil about 100 million years ago! One of the largest and fattest dinosaur fossils in Asia turned out to be a nearly complete skeleton when it was unearthed. Unfortunately, the first half of it has been excavated as a “keel”. Even so, the experts’ harvest here is very big, because many fossil spots and more dinosaur fossils have been found here.
As a kind of medicinal material, the keel has been used by Chinese for thousands of years. In ancient China, it can be imagined that most dinosaur fossils were also used as ordinary keels. Ancient people did not know that it had more precious value. According to local historical records, the keel of Puban, Shanxi Province, experienced the prosperous period of Tang and Song Dynasties, and became “never heard” in the Qing Dynasty. This shows that people eat a lot of keels. Now, people have questioned the medical use of the keel, because the formation of fossils is mainly due to the replacement of organic matter in the skeleton by minerals. If there are toxic elements in the formation process, the keel will be toxic, and it is dangerous to use it rashly. But the content of some trace elements in the keel is too high, which brings serious harm to the human body. In fact, traditional Chinese medicine is not without more safe ingredients similar to the keel. In recent years, people have found that oyster shell, magnet, jujube seed, pig bone and other herbs can almost replace the keel or even be more effective because of their similar ingredients. As an important evidence of historical research, “keel” will show its more precious value!
