Yin-Yang theory is not only an ancient Chinese philosophical theory, but also the core part of the basic theory of Traditional Chinese Medicine, which runs through all aspects of the theoretical system of Traditional Chinese Medicine. Gunpowder is one of the Four Great Inventions of ancient China and a symbol of China’s technological level at that time. It has a profound influence on the development of human civilization. Through the exploration of alchemy and gunpowder in early ancient China, it is found that Yin-Yang theory plays a very important role in the invention of gunpowder. Therefore, this paper discusses alchemy and Yin-Yang theory, the toxicity of Dan medicine and Yin-Yang theory, and the invention of gunpowder and the Yin-Yang theory.
