"Drug introduction" is a unique term in traditional Chinese medicine. Literally speaking, "drug introduction" is a magical substance, which can help Chinese medicine to play or enhance its medicinal properties, equivalent to the catalyst used in chemical reactions.

When Lu Xun was a child, his father was seriously ill. When he visited famous doctors in Shaoxing, his hometown, he was all Chinese medicine. According to the preface of Lu Xun's "Scream", Chinese medicine practitioners who treat Lu Xun's father like all kinds of strange "drug introduction". The more famous doctors, the more strange the "drug citation" used-

"reed roots in winter, sugar cane frosted for three years, yes crickets, flat wood with seeds, ... are not easy. 」

The sentence in quotation marks above is the original text of the preface to Lu Xun's Scream. If Mr. Lu Xun dares to write such a sentence so eloquently in such an important collection of short stories, he must not be lying.

Literally, these things are really hard to find, especially the "original cricket". How do I know if that cricket is the original one? If the cricket I caught is not the original match, but a halfway couple or a dew couple, will this "poisoning" be smashed? This prescription may not work, right? Can't this patient be cured?

Sure enough, Lu Xun's father was executed.

After his father died, Lu Xun decided to be a doctor when he grew up. Lu Xun had a very happy dream. After returning from studying abroad, he successfully cured many China people who were as sick as his father. On the way to study medicine, with more and more medical knowledge, Mr. Lu Xun gradually realized that Chinese medicine is empirical medicine, and such medicine is "just a liar intentionally or unintentionally." 」

Speaking of it, before the foundation of modern medicine such as anatomy was established, it was all medicine in the world, and almost all of them were "liars intentionally or unintentionally". We usually call it "witch doctor". At first, wizards and doctors were together, which was a way for people to fight diseases through the accumulation of experience from generation to generation.

People don't know the exact reason why the patient recovered. People only know that someone once suffered from the same disease. After the witch doctor used that method, the patient recovered. Therefore, people come to the conclusion that that method can treat that disease.

Before people knew immunology, people didn't know that people could heal themselves after illness. So the so-called treatment of a disease is likely to be futile and useless.

Such medicine developed purely by experience will certainly have many reasonable aspects, but before the corresponding principles are revealed, many experiences are purely useless medical methods. Therefore, in the face of modern medicine, some methods of Chinese medicine are just unintentional liars.

After the advent of modern medicine, some Chinese medicine practitioners still stubbornly believe that Chinese medicine is good, profound and unscientific, which is a deliberate lie.

Therefore, after learning some knowledge of western medicine and Chinese medicine, Mr. Lu Xun will certainly think that Chinese medicine is "nothing more than a liar intentionally or unintentionally." 」
