The 2015 White Paper on the Awareness of the Prevention and Treatment of Bone and Joint Diseases in China published big data showing that more than half of the people over 60 years old in China are suffering from knee diseases, and there is a recent trend of younger knee diseases. Cool weather, rainy days, and road strain can all lead to knee pain, so how do you relieve it? The “Ai” knee, moxibustion, yes, 10 minutes a day moxibustion, easy to get rid of knee disease. So, why can moxibustion relieve and cure bone and joint diseases? This is closely related to the nature and taste of moxa leaves and the cause of the disease. Mugwort is warm in nature and pungent in taste, which can disperse cold and dispel dampness, and the main cause of knee and bone joint diseases is the invasion of cold or dampness, which is what we usually call temperature-based knee difficulties and humidity-based knee difficulties, so moxibustion is a very suitable method. In addition to cold and dampness, moxibustion is also good for knee pain caused by acute knee sprains or bone spurs, but it should be noted that not all knee pain can be treated with moxibustion. For the above mentioned knee joint diseases, we have a basic point which is also a universal point for treatment, that is, the calf nose point, which is commonly known as the external knee eye, used by the ancients to treat knee flexion but not extension, and also mainly used in modern times to relieve the knee joint flexion and extension disadvantages. For different types of knee disorders, we can add different acupuncture points, such as the inner knee eye for knee pain, flexion and extension caused by cold. The Inner Knee Eye is an extra meridian point, the main function of which is to get rid of cold qi. Moxibustion of the Inner Knee Eye can help the heat to reach the inner part of the knee, thus getting rid of cold qi; for humidity type knee swelling and pain caused by dampness, we can add moxibustion of Yinlingquan, located on the inner side of the tibia, next to the tibial head. Yinlingquan is an acupuncture point of the spleen meridian, which is responsible for dampness, so moxibustion of Yinlingquan can dispel dampness and relieve tendons, which is very effective in the treatment of humidity-type knee disorders. It is worth mentioning that when we moxibustion body position to bend the knee 90 degrees is appropriate, while moxibustion acupuncture points will be two fingers next to the point to sense the temperature to prevent burns. The moxa stick can be burned horizontally after a period of time, so that the heat area will be larger and the effect will be better. The moxibustion time is 10-15 minutes, the skin is slightly red is appropriate, after moxibustion pay attention to keep warm to maintain the continuation of the healing effect, should not take a cold shower.
