Chinese medicine for fighting poison with poison

Chinese medicine has an empirical rule of "fighting poison with poison", and scorpions, centipedes and toads are the first choice for cancer treatment. In the medical history of our country, the idea of "immunity" has a long history, that is, the treatment method of "fighting poison with poison". Huangdi Neijing, the oldest medical work in China, mentioned that "poison" should be used to treat diseases, and drugs without "poison" could not cure diseases. But interestingly, Ge Hong, a Taoist immigrant obsessed with alchemy, was the first pioneer to put this immune thought into practice and engage in immunological research.

Modern medicine has proved that after a person is bitten by rabies virus, rabies virus penetrates into the human body through the wound. Because it has special affinity with nerve tissue, it leads to the attack of rabies. There are a large number of rabies viruses in the brain marrow and saliva of rabies. Pasteur, a famous French biologist, isolated rabies virus from rabies brain tissue and cultured it to make virus vaccine for preventing and treating rabies virus. Obviously, the principle used by Pasteur is basically similar to that used by Ge Hong, but it is more scientific than Ge Hong, but in terms of time, Pasteur's invention is later than Ge Hong's 1000 years.
