What acupoint is located four finger-widths below the navel?
Generally speaking, four fingers below the navel corresponds to the acupoint known as Guanyuan (CV4). The detailed explanation is as follows:
The width of four fingers typically measures about 3 cun. "Three cun below the navel" refers specifically to the Guanyuan acupoint. Located on the Conception Vessel (Ren Meridian) in the lower abdomen, along the anterior midline, Guanyuan lies three cun directly below the center of the navel. This acupoint functions to tonify the kidneys and strengthen vital energy, warm yang and prevent collapse, eliminate pathogenic factors, and relieve pain. It can be used to treat conditions such as shortness of breath due to kidney deficiency, nocturnal emission, impotence, hernia, frequent urination, hematuria, menstrual disorders, dysmenorrhea, functional uterine bleeding, uterine prolapse, and neurasthenia. Additionally, it helps regulate gastrointestinal dysfunction, treat cold-related diseases, boost immune function, and enhance the body's resistance to disease.
In daily life, one should consume moderate amounts of fresh fruits and vegetables, such as bananas and leafy greens, to replenish nutrients promptly. Regular physical activities like walking or yoga are also recommended.
