Moxibustion is a traditional therapy in Chinese medicine, which has the function of unblocking meridians, harmonizing qi and blood, helping to dispel evil, warming the meridians and dispersing cold. Moxibustion is generally recommended about 1 hour after a meal. The blood is concentrated in the body’s digestive system after a meal, and the qi and blood in the limbs and trunk are relatively weak, so moxibustion at this time may affect the effectiveness, and may also affect digestion, causing indigestion. The blood is redistributed to all the organs of the body about one hour after the meal, and the qi and blood tend to run smoothly, and the meridian qi is abundant, so the moxibustion method is more effective. In addition, patients can drink warm water after moxibustion to replenish the consumption of fluid during moxibustion, which can also help detoxification and strengthen the effect of moxibustion; at the same time, attention should be paid to keep warm to avoid the invasion of external evil. The moxibustion method is simple and has a wide range of applications, but it is important to note that it is not easy to moxibustion for those with skin damage or infection, and pregnant women are prohibited from moxibustion of the umbilicus, while patients should also pay attention to avoid burns when moxibustion.
