The Stomach Meridian, formally known as the Foot-Yangming Stomach Meridian, is one of the Twelve Meridians. According to Traditional Chinese Medicine, the Stomach Meridian is a meridian rich in qi and blood. It originates beside the nostrils (Yingxiang acupoint), runs upward alongside the nose, crosses over at the root of the nose, runs laterally to the inner canthus of the eye, intersects with the Foot Taiyang Bladder Meridian, descends along the lateral side of the nasal septum, enters the upper teeth, emerges again alongside the mouth, encircles the lips, descends to the Chengjiang acupoint, follows the posterior inferior margin of the mandible to the Dàyíng acupoint, runs alongside the Adam’s apple, enters the Qiépen acupoint, descends through the diaphragm, belongs to the Stomach, and connects to the Spleen. It has numerous branches and is widely distributed throughout the head, face, neck, chest, abdomen, and the anterolateral aspects of the lower limbs.
I. Functions of the Stomach Meridian
• Regulating Digestive System Function: The Stomach Meridian is directly connected to the stomach organ. Stimulating acupoints along the meridian—such as Zusanli (ST36) and Liangqiu (ST35)—can promote gastrointestinal peristalsis, enhance the stomach’s digestive and emptying capabilities, and help alleviate digestive issues such as loss of appetite, indigestion, stomach pain, bloating, and diarrhea.
• Nourishing the Head, Face, and Senses: The Stomach Meridian runs through the head, face, and sensory organs, providing qi and blood nourishment to the eyes, nose, mouth, and teeth. When the qi and blood in the Stomach Meridian are abundant and circulate smoothly, the facial skin becomes rosy and radiant, the eyes remain bright, and the teeth stay strong. It can also prevent and alleviate disorders of the head, face, and senses, such as toothaches, nasal congestion, and red, swollen, or painful eyes.
• Regulating the Circulation of Qi and Blood: As a meridian rich in both qi and blood, the Stomach Meridian plays a vital role in the circulation of qi and blood within the body. It transports the essence of food and drink—transformed by the spleen and stomach—throughout the body, providing nutrients to all organs and tissues and maintaining their normal physiological functions. At the same time, regulating the qi and blood of the Stomach Meridian helps improve conditions such as qi and blood stagnation, and plays a role in alleviating symptoms such as bodily pain and numbness.
• Boosting the Body’s Immunity: The abundance of qi and blood in the Stomach Meridian is closely related to the strength of the body’s “ Zhengqi ” (vital energy). According to Traditional Chinese Medicine theory, the spleen and stomach are the “foundation of postnatal life” and the “source of qi and blood generation.” Sufficient qi and blood in the Stomach Meridian ensures an abundance of Zhengqi, enhancing the body’s ability to resist external pathogens, boosting immunity, and preventing the onset of disease.
• Regulating Emotional Well-being: The Stomach Meridian is also linked to emotional well-being. When qi and blood in the Stomach Meridian are out of balance, emotional issues such as irritability, depression, and insomnia may arise. By regulating the Stomach Meridian, one can improve the state of qi and blood to a certain extent, thereby regulating emotional well-being and alleviating mental stress.
II. Blockages in the Stomach Meridian Can Have Adverse Effects on Multiple Aspects of the Body
1. Digestive System Issues
• Loss of Appetite: Blockages in the Stomach Meridian can disrupt the normal rise and fall of stomach qi, leading to dysfunction in the spleen and stomach’s transport and transformation functions, which in turn causes symptoms such as loss of appetite and poor food intake.
• Indigestion: The digestion and emptying of food in the stomach are impaired, making one prone to symptoms such as indigestion, bloating, and stomach pain, which may also be accompanied by belching and acid reflux.
• Constipation or Diarrhea: The Stomach Meridian is interconnected with the Large Intestine Meridian; obstruction in the Stomach Meridian may affect the Large Intestine’s ability to transmit and eliminate waste, leading to intestinal issues such as constipation or diarrhea.
2. Abnormalities in the Head, Face, and Senses
• Facial Issues: The Stomach Meridian runs through the face; impaired circulation of qi and blood in this meridian can lead to insufficient supply of qi and blood to the face, resulting in a sallow, dull complexion, as well as problems such as dark spots and acne.
• Oral Diseases: Stomach fire rising along the meridian to the mouth may cause oral problems such as toothaches, swollen and painful gums, and bad breath, and may also lead to recurrent mouth ulcers.
• Eye Discomfort: Impaired flow of qi and blood in the Stomach Meridian may affect the nourishment of the eyes, resulting in symptoms such as dry eyes and blurred vision.
3. Problems with the Limbs and Muscles
• Lower Limb Pain: The Stomach Meridian runs down the anterior-lateral aspect of the lower limbs; obstruction leads to pain, potentially causing discomfort such as pain, numbness, soreness, and distension in areas like the knee joints and the front of the calves, which can affect walking and daily activities.
• Muscle Atrophy: Prolonged obstruction of the Stomach Meridian deprives the lower limb muscles of adequate nourishment from qi and blood, potentially leading to gradual muscle atrophy, reduced muscle strength, and impaired motor function in the limbs.
4. Mental and Emotional Aspects
• Irritability and Short Temper: Imbalances in qi and blood in the Stomach Meridian may affect the mind, leading to emotional issues such as restlessness, irritability, and a short temper. This makes individuals prone to emotional fluctuations and unable to maintain a calm state of mind.
• Insomnia and Vivid Dreams: Disharmony between the Spleen and Stomach can impair sleep quality, resulting in insomnia symptoms such as difficulty falling asleep, vivid dreams, and frequent awakenings. Over time, this may also lead to poor mental well-being and memory decline.
5. Other Issues
• Weakened Immunity: Blockages in the Stomach Meridian can impair the Spleen and Stomach’s function as the “foundation of acquired vitality,” leading to insufficient production of qi and blood and a weakness in the body’s vital energy. This, in turn, weakens the body’s immune system, making it more susceptible to external pathogens and triggering various illnesses such as colds and coughs.
• Menstrual Irregularities: In women, the Stomach Meridian is interconnected with meridians such as the Chong Meridian. Blockages in the Stomach Meridian may disrupt the flow of qi and blood in the Chong and Ren meridians, leading to gynecological issues such as menstrual irregularities and dysmenorrhea.
III. Stomach Meridian Health Maintenance
To stimulate the Stomach Meridian, one can focus on acupoint massage, exercise, dietary adjustments, and external TCM therapies. Specific methods are as follows:
1. Acupoint Massage
• Zusanli (ST36): Located on the outer side of the lower leg, 3 cun below Dubi, and one finger-width lateral to the anterior crest of the tibia. Use the pad of your thumb to press and knead the Zusanli acupoint, massaging each leg for 3–5 minutes until a sensation of soreness and fullness is felt. This helps regulate gastrointestinal function and promotes the circulation of qi and blood in the Stomach Meridian.
• Tianshu (ST25): Located on the abdomen, at the level of the umbilicus, 2 cun lateral to the anterior midline. Use the thumbs of both hands to apply moderate pressure to the Tianshu point, massaging for 2–3 minutes each time. This helps regulate gastrointestinal function and promote the flow of qi and blood in the Stomach Meridian.
• Liangqiu (ST34): With the knee bent, this point is located on the front of the thigh, 2 cun above the lateral end of the patellar base. Press the Liangqiu acupoint with your fingers; once you feel a dull ache, continue applying pressure for 1–2 minutes to relieve stomach pain and promote the circulation of qi and blood in the Stomach Meridian.
2. Exercise
• Tai Chi: With its slow, gentle movements, Tai Chi regulates breathing and ensures the smooth flow of qi and blood. During practice, movements such as bending, stretching, and rotating stimulate meridians like the Stomach Meridian, enhancing the functions of the spleen and stomach and promoting the circulation of qi and blood in the Stomach Meridian.
• Baduanjin: Through various postures and movements that stretch and twist different parts of the body, specific exercises—such as “Regulating the Spleen and Stomach by Raising One Arm”—effectively stimulate the Stomach Meridian, enhance the spleen and stomach’s transport and transformation functions, and unblock the Stomach Meridian.
• Jogging: Moderate jogging promotes whole-body blood circulation, enhances gastrointestinal peristalsis, and facilitates the smooth flow of qi and blood in the Stomach Meridian. It is recommended to engage in these activities 3–5 times per week, for about 30 minutes each time.
3. Dietary Adjustments
• Eat more foods that strengthen the spleen and nourish the stomach: Moderately consume foods such as Chinese yam, Job’s tears, water caltrop, and white kidney beans. These foods have the effect of strengthening the spleen and benefiting the stomach, helping to enhance spleen and stomach function and promote the generation and circulation of qi and blood in the Stomach Meridian.
• Maintain a regular eating schedule: Eat at set times and in appropriate portions; avoid overeating; and strive to maintain a consistent three-meal-a-day routine to ensure the normal transport and transformation functions of the spleen and stomach, which facilitates the smooth flow of qi and blood in the Stomach Meridian.
4. External Treatment Methods in Traditional Chinese Medicine
• Moxibustion: Select acupoints such as Zusanli (ST36), Zhongwan (CV12), and Weishu (BL21). Light a moxa stick and hold it above the acupoints to apply heat; the treatment should be performed until the skin feels warm but without a burning sensation. Apply moxibustion to each acupoint for 15–20 minutes per session to warm and unblock the Stomach Meridian, dispel cold, and relieve pain.
• Cupping: Apply cupping near the Weishu acupoint on the Bladder Meridian (Foot-Taiyang) on the back and along the course of the Stomach Meridian on the front of the thigh. This helps unblock the meridians, promote the flow of qi and blood, and facilitate the opening of the Stomach Meridian.
• Gua Sha: Use a gua sha scraper to perform gua sha along the Stomach Meridian’s course—such as the anterior-lateral aspect of the lower leg—until the skin develops faint red or purplish-red marks. This promotes the circulation of qi and blood in the Stomach Meridian and helps eliminate toxins from the body.
