The Qing Dynasty had a miraculous "knife tip medicine", why later disappeared?

Why did the Qing Dynasty knife tip medicine later disappeared? The main reason is because his recipe for medicine is too expensive, and then even more so, do not allow mining, knife tip medicine what effect? Knife tip medicine is in addition to beheading injuries can not be cured other knife wound a compress on the good, since it has such a magical effect ah, that his formula medicine is also very expensive, he one of the medicine is called keel, plus keel after the knife tip to be said to be the effect of magical, but the knife tip medicine is missing this keel then, the effect of the drug is no effect on the medicine has become worthless.

Dragon bone is the key to the tip of the medicine, without him the tip of the medicine is no efficacy, in fact, the dragon bone is an animal bone, due to the discovery of the efficacy of this medicine, people from all over the world to buy this medicine to prepare for injuries, in fact, he is now Yunnan Baiyao cream it, can be a large number of manufacturing tip of the medicine, animal bone consumption is too large, a moment of the supply does not come up, so this medicine also disappeared.

The second is the dragon bone it is the record of the oracle bone object, the state is not allowed to mine this thing, the important formula of the knife tip medicine dragon bone in the Qing Dynasty is an important source of Henan Anyang's dragon bone, this dragon bone above the engraved word, then someone high price to buy this dragon bone to study, and then this kind of they found that the dragon bone to sell to the oracle bone seller more profit, so the dragon bone to give up! As the use of knife tip medicine, and then this trend has continued until the liberation, so the knife tip medicine is no way to go back to manufacturing.

Thirdly, China developed a new hemostatic drug, which then replaced the development of the knife tip medicine, so the knife tip medicine has since withdrawn from the stage of history, making it difficult for us to see the knife tip medicine today.
