There have been records of using ink as medicine in Tang Dynasty. Throughout the medical books of past dynasties, "ink" was mainly used as a hemostatic. For example, when vomiting blood and nosebleeds (nosebleeds), you can drink it. Tongrentang still has Jingxiang mill, a kind of medicinal material from the origin of Huimo.
The main component of ink is carbonized particles. According to the contemporary "scientific understanding and explanation", its rough surface can promote the coagulation mechanism to play a role. But the ancients didn't have this knowledge. Why do they use ink as a hemostatic?
In the "five elements" theory, black belongs to water and red belongs to fire; Water can kill fire and black can kill red-so black ink can kill red blood. The theory of five elements provided a thinking tool for the ancients to use natural things, which was proved to be effective as experience and preserved by practice. Those that cannot stand the test of practice will naturally be eliminated.
