In TCM theory, the meridians of the human body are all over the body and play the role of linking the internal organs, communicating the internal and external flow of qi and blood, nourishing the whole body, resisting diseases and evils, and defending the body. It not only guides the clinical practice of various departments of Chinese medicine, but also is an important basis for human health care and health care to dispel diseases. It is crisscrossed throughout the body, and once a meridian is not working, it will cause a lot of trouble, just like traffic congestion and blocked water pipes. How can you tell if your meridians are open? Here are a few simple and easy to use small methods. 1, pinch flesh method. According to Chinese medicine, “if it’s clear, it’s not painful, if it’s painful, it’s not clear”. Therefore, you can use the meat pinching method to determine whether your meridians are smooth. Use your hands to pinch up the flesh of your body, especially the outside of the leg through the bile meridian, the front of the leg through the stomach meridian, the inside of the leg through the kidney meridian, as well as the inner and outer sides of the upper arm, if the pinch is very painful, it means that you may be a meridian is not working, and the more painful, the more serious the meridian is blocked. In addition, some people’s backs are as hard as iron plates, others a little pinching pain, and often feel particularly tired all day and night. This is also a manifestation of meridian blockage, indicating that the back of his bladder meridian is blocked. 2, over the blood method. Clench the wrist of the other hand with one hand, after about 1 minute, you will see the palm of the wrist clenched gradually from red to white, then, suddenly release the wrist, you will feel a stream of heat straight to the fingertips, while the palm will also gradually turn from white to red, this phenomenon is called over blood. If the palm of your hand returns to its normal color within half a minute, it means your meridians are open. If your palm does not return to its normal color within half a minute, it means your meridians may not be open enough. 3. Observe the abnormal changes in your body. Abnormalities in the Hand Taiyin Lung meridian manifest as the following symptoms: fullness in the lungs, swelling and shortness of breath, coughing, pain in the middle of the two supraclavicular fossae (missing pelvis) (including the throat part); in severe cases, cross-cupping both hands, feeling boredom in the chest and blurred vision. Qi and blood obstruction in the forearm may also occur, with syncope, coldness, numbness and pain.
