Endometriosis and Blood StasisTraditional Chinese Medicine Perspective

By Wesley Zhang, L.Ac

Endometriosis is a chronic gynecologic condition in which tissue similar to the lining of the uterus grows outside the uterine cavity. It can be associated with painful menstruation, chronic pelvic pain, pain during intercourse, digestive or urinary discomfort, and difficulties with fertility. From a conventional medical perspective, endometriosis involves complex interactions among inflammation, estrogen activity, immune responses, and abnormal tissue growth. Traditional Chinese Medicine (TCM) approaches the condition from a different but complementary perspective. Rather than treating the diagnosis alone, TCM asks why pain is occurring, what happens throughout the menstrual cycle, how the symptoms change over time, and what constitutional patterns may be contributing to the patient’s condition.

One of the most important concepts in TCM when working with endometriosis is Blood Stasis, or Xue Yu. Blood Stasis does not simply mean that blood is physically “stuck.” It describes a pattern in which the normal movement of Blood is impaired, often reflected clinically by fixed or stabbing pain, dark menstrual blood, clots, prolonged menstrual discomfort, or pain that becomes more intense before or during menstruation. The classic TCM principle, “不通则痛,” can be translated as “when there is obstruction, there is pain.” For many patients with endometriosis, this concept provides a useful framework for understanding why the pain can be severe and why it may follow a predictable menstrual pattern.

However, Blood Stasis is rarely the entire picture. The Liver plays an important role in the regulation of Qi and the smooth movement of Blood. Chronic emotional stress, frustration, poor sleep, and prolonged tension may contribute to Liver Qi stagnation. When Qi does not move properly, Blood may also become stagnant. Over time, repeated stagnation can contribute to a more fixed pattern of pain. This is one reason why two women with the same medical diagnosis can experience very different symptoms. One may have severe premenstrual irritability and breast tenderness together with pelvic pain, while another may primarily experience fatigue, digestive problems, low back discomfort, and infertility.

Cold can also be an important factor in certain patients. In TCM, Cold contracts and slows circulation. A patient whose pelvic pain is significantly worse with cold exposure and improves with warmth may present a different pattern from someone with signs of Heat or inflammatory activity. This is where individualized diagnosis becomes particularly important. Moxibustion treatment, for example, may be considered when Cold and deficiency are prominent, but it should not be applied indiscriminately to every patient with endometriosis. Treatment must follow the pattern rather than the disease name.

Another important distinction is between excess and deficiency. In the early or more painful stages of a condition, obstruction such as Qi stagnation and Blood Stasis may dominate. In a patient who has lived with endometriosis and chronic pain for many years, however, underlying deficiency may become more apparent. Spleen Qi deficiency may present with fatigue, bloating, loose stools, and poor energy. Kidney deficiency may be associated with low back soreness, weakness, menstrual irregularity, or reproductive difficulties. In these cases, simply trying to “move Blood” aggressively may not be appropriate. The treatment may need to move Blood while simultaneously supporting the patient’s underlying Qi, Blood, Spleen, or Kidney system.

I often explain to patients that TCM treatment is not simply about trying to make the pain disappear. Pain is important information. Its location, timing, quality, relationship to menstruation, response to warmth, and relationship to emotional stress can all help guide diagnosis. A sharp, fixed pain with dark clots suggests a different pattern from a dull, dragging pain associated with fatigue and weakness. Likewise, severe menstrual pain accompanied by irritability and breast tenderness may require a different strategy from severe pain accompanied by cold hands and feet and improvement with heat. This diagnostic process is one of the strengths of Traditional Chinese Medicine: the same Western diagnosis does not necessarily lead to the same TCM treatment.

Acupuncture may be used as part of an individualized treatment plan to support pain regulation, relaxation, circulation, and overall menstrual balance. In my clinical experience, patients often notice that treatment affects more than their pelvic discomfort. Sleep, stress levels, muscle tension, digestion, and the overall experience of the menstrual cycle may also change. Chinese herbs and individualized Herbal medicine can be considered when a patient needs a more comprehensive approach, particularly when Blood Stasis is combined with Qi stagnation, Cold, Dampness, or deficiency. Auricular acupuncture or ear seeds may also be useful as supportive approaches for stress and symptom management between treatments.

One patient in my practice presented with longstanding severe menstrual pain. Her pain was deep and relatively fixed, beginning several days before menstruation and becoming especially intense during the first two days of her period. She also reported dark menstrual blood and frequent clots. Her tongue was somewhat dusky, and her pulse was wiry and relatively choppy. From a TCM perspective, the presentation was consistent with Blood Stasis combined with Liver Qi stagnation. Treatment focused on regulating Qi and moving Blood while carefully monitoring her response throughout the menstrual cycle. Over time, she reported that her menstrual pain became less intense and that her periods were easier to manage. The goal was not to claim that acupuncture or herbs had eliminated the underlying endometriosis, but rather to support her symptoms and quality of life as part of a broader care plan.

Another patient had a very different presentation. She had a history of endometriosis accompanied by chronic fatigue, low back soreness, bloating, and reproductive concerns. Her tongue was pale and slightly swollen with tooth marks, and her pulse was deep and weak. Although Blood Stasis remained part of the clinical picture because of her chronic pelvic symptoms, her overall presentation suggested that deficiency was also important. Her treatment therefore emphasized supporting the Spleen and Kidney while gently addressing Blood Stasis rather than using a strongly dispersing approach. This illustrates an important principle of TCM: chronic gynecologic disease may gradually affect the whole body, and treatment needs to evolve as the patient’s condition changes.

For women living with endometriosis, fertility can become another major concern. TCM traditionally views reproduction as closely related to the Kidney, Liver, Spleen, Qi, Blood, and the proper movement of Blood through the reproductive system. When fertility is affected, the goal is not simply to focus on the uterus or ovaries. Sleep, digestion, stress, menstrual regularity, energy, and constitutional strength may all be relevant. Acupuncture and Chinese herbs may be used as complementary support, while conventional fertility evaluation and treatment remain important when indicated.

Endometriosis is a condition that deserves serious medical attention, particularly when pain is severe, progressive, or associated with infertility, abnormal bleeding, or bowel and urinary symptoms. Gynecologic evaluation and appropriate imaging or surgical assessment may be necessary depending on the individual case. TCM should not be viewed as a replacement for conventional diagnosis or treatment. Instead, it can offer another clinical perspective, particularly for symptom management, stress regulation, menstrual support, and individualized care.

From the TCM perspective, endometriosis is not simply a disease of the reproductive organs. It may reflect a long-standing interaction between obstruction and deficiency, between Blood Stasis and Qi stagnation, and between constitutional factors and the demands of modern life. Effective care begins by understanding the individual rather than treating every patient according to the same formula. When acupuncture, Chinese herbs, lifestyle support, and appropriate conventional medical care are thoughtfully integrated, the goal is not merely to treat a diagnosis, but to help a woman regain greater comfort, stability, and confidence in her own health.
