TCM for Irregular Menstruation: Pattern Differentiation

1. Why TCM Distinguishes Four Patterns

A "normal" menstrual cycle in TCM is considered to be 28 to 30 days, lasting 3 to 7 days, with moderate flow that is red without large clots, minimal pain, and no significant premenstrual distress. Deviation from this is meaningful: the direction of the deviation tells you what is happening internally. A cycle that is consistently too early is a heat pattern; one that is consistently too late is a cold or deficiency pattern. A cycle that swings back and forth is a Liver Qi pattern. The absence of a cycle for months is a deep deficiency pattern.

This is why TCM does not have a single "irregular periods" formula. Each pattern requires different foods, different acupressure emphasis, and different lifestyle adjustments. Applying a heat-clearing diet to a cold-deficiency pattern would worsen it, and vice versa. The table below is the most important part of this article: identify your pattern first, then choose the matching advice.

Emotional patterns are tightly linked to menstrual patterns through the Liver. The Liver governs the free flow of qi, and the Liver meridian circles the reproductive organs — which is why premenstrual mood changes are so common, and why stress so often shifts the cycle. See our guide on natural approaches to PMS for more on the Liver-period connection.

2. The Four-Pattern Differentiation Table

Read down the column for your pattern, then check the matching sections below. Many women have a mixed pattern (for example, late and unpredictable, or cold complicated by some Liver Qi stagnation); in that case combine the advice, or consult a licensed practitioner for a personalized assessment.

3. Acupressure Points for All Four Patterns

Three acupressure points form the foundation for irregular menstruation. The same three points are used in all four patterns, but the emphasis and combination differ.

SP6 — Sanyinjiao (Three Yin Crossing)

On the inner lower leg, about four finger-widths above the inner ankle bone. SP6 is the meeting point of the Spleen, Liver, and Kidney meridians, and the single most important point for any menstrual issue. It tonifies the Spleen (builds blood), regulates the Liver (moves qi), and nourishes the Kidney (warms the uterus). For full location and technique, see our dedicated SP6 acupressure guide.

LR3 — Taichong (Supreme Rushing)

On the top of the foot, in the web between the big and second toes. LR3 moves Liver Qi and is the most important point for the unpredictable cycle pattern. Use it daily when stress or mood swings are prominent, and especially in the week before the period.

CV4 — Guanyuan (Gate of Origin)

On the midline of the lower abdomen, three finger-widths below the navel. CV4 warms and tonifies the Lower Jiao and is especially useful for the late period and amenorrhea patterns. Use a warm hand, warm compress, or gentle moxa. Avoid abdominal pressure during pregnancy and the heaviest flow days.

4. Foods for Each Pattern

Diet must follow the pattern. Eating the wrong category of food for your pattern can actively worsen it.

For Early Periods (Heat)

• Favor: mung beans, celery, cucumber, lotus root, pear, chrysanthemum tea, and lightly cooked greens.
• Avoid: spicy food, lamb, heavy warming spices (cinnamon, cloves), alcohol, and fried food.

For Late Periods (Cold or Deficiency)

• Favor: ginger, dates, goji berries, black beans, black sesame, small amounts of lamb or beef, warm soups and congees.
• Avoid: raw, cold, and iced foods; excessive raw salads and tropical fruits.
• See our guide to blood-nourishing foods for a complete list.

For Unpredictable Periods (Liver Qi Stagnation)

• Favor: tangerine peel (chenpi), rose tea, chrysanthemum tea, radish, mint, and lightly spiced, easy-to-digest meals.
• Avoid: heavy, greasy foods, alcohol, and excess coffee, all of which worsen Liver Qi stagnation.

For Amenorrhea (Blood or Kidney Deficiency)

• Favor: deeply nourishing foods — bone broth, dates, goji berries, black sesame, black beans, dark grapes, eggs, and small amounts of organ meat if you eat it.
• Avoid: extreme diets, fasting, and raw/cold foods, which deepen deficiency. Restore adequate caloric and iron intake.
• Amenorrhea after extreme weight loss, stress, or overtraining is a medical concern — see a healthcare provider before relying on diet alone.

5. Lifestyle Support Across All Patterns

Beyond pattern-specific foods and acupressure, several habits support every menstrual pattern. Regular sleep before 11 PM protects Kidney Yin and Liver blood — late nights directly worsen both the heat and the deficiency patterns. Consistent, moderate exercise (walking, gentle yoga, tai chi, swimming) moves qi and blood without exhausting the body — avoid intense training during amenorrhea or heavy-flow days. Stress management is non-negotiable for the Liver Qi pattern; daily breathing, journaling, or qigong calms the Liver and stabilizes the cycle. Warmth matters in every pattern except the heat pattern: keep the lower back, abdomen, and feet warm, especially in the week before the period. Tracking your cycle for 3 months — dates, flow, mood, and any triggers — gives you and any practitioner the clearest picture of your pattern.

Frequently Asked Questions

What are the four TCM patterns of irregular menstruation?

The four classical patterns are: (1) early periods (cycle shorter than 21 days) caused by heat in the blood, often with heavy red flow; (2) late periods (cycle longer than 35 days) caused by cold or deficiency, often with pale scanty flow; (3) unpredictable periods caused by Liver Qi stagnation, often with emotional triggers and clots; (4) amenorrhea (no period for 3 or more months) caused by severe blood deficiency or Kidney essence deficiency. Each pattern has a different treatment direction.

Which acupressure point is best for irregular periods?

SP6 (Sanyinjiao) on the inner lower leg is the single most important point for irregular menstruation. As the meeting point of the Spleen, Liver, and Kidney meridians, it regulates all three organ systems involved in menstruation. It is combined with LR3 (Taichong) on the foot to move Liver Qi for the unpredictable pattern, and CV4 (Guanyuan) below the navel to warm and tonify the uterus for the late or amenorrhea pattern.

What foods help regulate menstruation in TCM?

Foods depend on the pattern. For early periods (heat): cooling foods like mung beans, celery, and chrysanthemum tea. For late periods (cold/deficiency): warming and blood-nourishing foods like ginger, dates, lamb in moderation, black beans, and goji berries. For unpredictable periods (Liver Qi): qi-moving foods like tangerine peel, rose tea, and radish. For amenorrhea (deficiency): deeply blood-nourishing foods like bone broth, dates, goji berries, and black sesame. See our blood-nourishing foods guide.

When should I see a doctor for irregular periods?

See a healthcare provider if your cycle is consistently shorter than 21 days or longer than 35 days, if you miss periods for 3 or more months (and are not pregnant), if bleeding is very heavy or prolonged, if you have severe pain, if you have bleeding between periods or after menopause, or if irregular cycles are accompanied by weight changes, excess hair growth, or fertility problems.
