Xue Blood 血

1. What is Blood (Xue) in Traditional Chinese Medicine (TCM)?

Blood (血, Xue) is one of the vital substances in TCM, essential for nourishing, moistening, and sustaining life. It is a dense, Yin substance that flows through the body, carrying nutrients, cooling the organs, and anchoring the Mind (Shen, 神). Blood is closely related to Qi, as Qi generates, moves, and holds Blood in place.

2. What are the functions of Blood?

Blood plays a key role in the body's physiology and mental-emotional well-being. It has four primary functions:

1. Nourishing the Body

• Blood delivers essential nutrients to the organs, tissues, muscles, skin, and bones.
• It supports growth, energy, and vitality.
• Key Acupuncture Points: SP-6 (Sanyinjiao, 三阴交), ST-36 (Zusanli, 足三里).

2. Moistening the Body

• Blood prevents dryness by moistening the skin, eyes, hair, sinews, and joints.
• Liver-Blood, in particular, keeps the eyes and sinews flexible.
• Key Acupuncture Points: LIV-8 (Ququan, 曲泉), SP-10 (Xuehai, 血海).

3. Housing and Anchoring the Mind (Shen, 神)

• Blood provides the material foundation for the Mind, keeping emotions stable.
• If Blood is deficient, symptoms like anxiety, restlessness, insomnia, and dream-disturbed sleep may arise.
• Key Acupuncture Points: HT-7 (Shenmen, 神门), REN-4 (Guanyuan, 关元).

4. Regulating Menstruation

• Blood is responsible for a regular and healthy menstrual cycle.

3. How is Blood produced in the body?

Blood originates from multiple sources, including Qi, Essence (Jing, 精), and digestion.

1. Food-Qi (Gu Qi, 谷气) and Blood Formation

• Food-Qi from the Spleen and Stomach is transported to the Heart, where it is transformed into Blood.
• Key Acupuncture Points: ST-36 (Zusanli, 足三里), REN-12 (Zhongwan, 中脘).

2. Kidney Essence (Jing, 精) and Blood

• Essence (Jing) transforms into Blood, ensuring deep nourishment and supporting long-term vitality.
• This is particularly important in women’s reproductive health.
• Key Acupuncture Points: KI-3 (Taixi, 太溪), BL-23 (Shenshu, 肾俞).

3. The Role of the Lungs and Liver

• Lung-Qi assists Blood formation by ensuring proper circulation.
• Liver stores Blood, regulates its distribution, and ensures a smooth menstrual cycle.

4. What is the relationship between Blood and Qi?

Qi (气) and Blood (血) are closely interconnected, influencing each other in four key ways:

1. Qi Generates Blood

• Food-Qi (Gu Qi), transformed into Blood, relies on Spleen-Qi and Lung-Qi.
• Key Acupuncture Points: SP-6 (Sanyinjiao, 三阴交), ST-36 (Zusanli, 足三里).

2. Qi Moves Blood

3. Qi Holds the Blood

• Qi keeps Blood within the vessels, preventing excessive bleeding (e.g., heavy periods, nosebleeds).

4. Blood Nourishes Qi
