Insomnia is very common, and patients are often accompanied by anxiety and tension. Chinese medicine believes that the location of insomnia is in the heart, and the pathogenesis is due to the disturbance of the heart and mind and the failure of Yang to enter Yin. The treatment is based on clearing heat, resolving phlegm and invigorating blood. Commonly used prescriptions include Gentian Diarrhea Liver Soup, Gardenia Black Bean Soup, Huang Lian Wen Bile Soup, Blood Mansions and Blood Stasis Soup, Chai Hu Plus Dragon Bone and Oyster Soup, etc.; Yang does not enter Yin, mostly due to deficiency of Yin and Blood, Yin deficiency and fire, Yang cannot be hidden. However, clinical Yang deficiency type of insomnia is often overlooked. Generally speaking, Yang deficiency is mainly due to fatigue and sleepiness, so how can it cause insomnia? The phrase “Yang qi is open when one is bothered by labor” explains the pathogenesis of Yang deficiency insomnia. When people are active, Yang Qi will be open outside, and if we are too tired, Yang Qi will be weak and floating, and we will experience what Zhu Wei Ju calls “deficiency hyperactivity”, which can be seen clinically. When I am tired at work, I tend to have poor sleep conditions and have difficulty falling asleep, dreamy and wake up early. Zhu Weiju has unique experience in treating this type of insomnia and advocates the “warm and subtle method”, which is based on warming Yang and complemented by medicines such as Jieshi and Gan Run to nourish the heart. Commonly used in combination with drugs such as Pseudostellaria, magnetism, dragon’s tooth and jujube seeds.
