Spleen (SP)

Overview

The Spleen meridian follows the Stomach's peak time, active from 9-11 AM, which represents the period when the body is most actively transforming the morning meal into usable energy. This timing underscores the importance of eating a nourishing breakfast during Stomach time (7-9 AM) and allowing the Spleen to process it during its own peak hours.

The Spleen's role as the Root of Post-Heaven Qi makes it arguably the most clinically important organ in Chinese medicine for treating chronic disease. While acute conditions often involve the Lung (external pathogens) or Liver (Qi stagnation), chronic conditions almost invariably involve Spleen deficiency at some level. This is because the body's capacity to generate Qi, blood, and immune function depends entirely on the Spleen's ability to extract nourishment from food. When the Spleen fails, the raw material for every other organ's function diminishes.

SP-6 (San Yin Jiao) deserves special mention as one of the most remarkable points in the entire meridian system. Located three cun above the medial malleolus, it is the meeting point of the Spleen, Liver, and Kidney meridians -- the three Yin channels of the leg. This convergence gives SP-6 the unique ability to simultaneously address digestive disorders (Spleen), menstrual and emotional conditions (Liver), and Kidney-related issues of fertility, urination, and constitutional strength. It is one of the most commonly used points in gynecological acupuncture and is contraindicated in pregnancy due to its powerful effect on the uterus.

Pathway

The Spleen meridian begins at the medial tip of the great toe (SP-1, Yin Bai), ascends along the medial aspect of the foot, passes anterior to the medial malleolus, continues up the medial leg along the posterior border of the tibia, crosses the knee at the medial condyle, ascends the medial thigh, enters the abdomen, connects with the spleen and stomach, traverses the diaphragm, ascends alongside the esophagus to the root of the tongue where it disperses across the undersurface. A branch separates in the stomach region, passes through the diaphragm, and enters the heart to connect with the Heart meridian.

Functions

The Spleen meridian governs the transformation and transportation of food essence and body fluids. It extracts Gu Qi (grain Qi) from food and transports it upward to the Lung and Heart for the production of Qi and blood. The Spleen raises clear Yang upward, keeping organs in their proper position and preventing prolapse. It also controls blood by keeping it within the vessels, and it governs the muscles and four limbs, providing the nourishment that gives them substance and strength.

Common Symptoms of Imbalance

Bloating after meals, loose stools with undigested food, fatigue (especially after eating), heavy limbs, edema, prolapse of organs, bruising easily, heavy menstrual bleeding, poor appetite, sweet cravings, overthinking and worry, difficulty concentrating when studying, muzzy-headed feeling, weight gain around the middle, varicose veins

Balancing Practices

Eating warm, cooked foods at regular intervals in a calm environment. Avoiding cold drinks, excessive raw food, and refined sugar that burden the Spleen. Moderate exercise (walking, tai chi) that moves Qi without depleting it. The Spleen Sound (Whoo) from Six Healing Sounds qigong. Abdominal self-massage. Reducing mental stimulation and screen time. Singing, which vibrates the middle burner. Moxibustion on SP-6 and ST-36 to warm and tonify the Spleen.
