The San Jiao meridian, or San Jiao meridian in full, is a meridian that regulates qi and channels water. If the San Jiao meridian is blocked, abnormal symptoms will appear in the meridian’s circulation. The San Jiao meridian starts from the ulnar end of the ring finger, travels up the back of the hand, between the ulna and radius, along the outer side of the upper arm, up to the shoulder, and passes through the diaphragm in front of the chest, extensively belonging to the San Jiao. Its branches go up to the neck and neckline, around the ears, toward the cheeks, and to the canthus of the eye. If the San Jiao meridian is blocked, the corresponding symptoms can appear in the parts it travels to, such as eye pain, pain behind the ear, tinnitus and deafness, cheek swelling and pain, pain on the outside of the arm, numbness of the ring finger, etc. If the patient’s San Jiao meridian is blocked, the corresponding symptoms can appear in the parts it travels to. If the patient’s San Jiao meridian blockage symptoms are more obvious, it is recommended to find a professional Chinese medicine practitioner for acupuncture or moxibustion treatment, appropriate to take some traditional Chinese medicine to regulate, usually keep a happy mood, and develop good eating habits.
