Moxibustion is one of the more common treatments in Chinese medicine, and in general, moxibustion cannot be performed at night, but in special cases, such as treating certain diseases with moxibustion, it can be implemented at night. The main role of moxibustion is health care, which generally cannot be performed at night, because moxibustion has the effect of warming the Yang and dispersing cold, opening the meridians, moving the Qi and blood, which is beneficial to the body to replenish Yang energy. In the evening, the body’s yang energy is slowly coming in from outside the body, and will gradually enter a sleepy, sleepy state. If moxibustion is carried out at this time, it will lead to the re-growth of yang energy, which will injure yin and move blood, thus making the human body hot and bothered, dry mouth and tongue, and insomnia. Usually, moxibustion for health care is done in the morning because it is the morning when yang energy grows and develops, so moxibustion can be done in accordance with the time of day and have a better health care effect. If the purpose of moxibustion is to treat diseases, such as certain diseases at night, moxibustion can be performed at night, such as dysmenorrhea caused by cold condensation in the uterus, insomnia caused by cold or qi deficiency, etc. The benefits of moxibustion at night outweigh the harm and help promote recovery from the disease.
