Case: A woman in her thirties with severe lower abdominal pain before menstruation through day one, clots in menstrual blood, breast distension, and irritability. Warmth brings relief. The tongue is dark with stasis patches; the pulse is deep and wiry.
1. Conventional pattern differentiation and treatment
Dysmenorrhea attributed to qi stagnation and blood stasis. Regulate qi and move blood; points: Sanyinjiao, Xuehai, and Taichong. This conventional approach omits the element of cold suggested by relief with warmth.
2. Mapping the case to the nine nine MLMN layers
| L2 Etiology | Combined stress (liver constraint) and cold (cold pathogenic influence) |
|---|---|
| L4 Qi, blood, and body fluids | Cold congealing overlaps qi stagnation and blood stasis (relief with warmth interpreted as cold congealing with blood stasis) |
| L3 Zang-fu | Liver (coursing and discharge) plus chong and ren vessels (uterus) |
| L8 Environment | Worsening with cold and cold environments (external cold as a trigger) |
| L9 Temporal phase | Complete linkage with the menstrual cycle: the theoretical effect of intervention varies with the cycle phase |
3. Comparative hypotheses within MLMN
Regulating qi and moving blood alone may overlook cold (L2 and L4). Compare priorities between warming the channels and dispersing cold, and moving blood. From L9 temporal phase, observe what changes between ovulation and menstruation. Update treatment hypotheses and timing through post-treatment changes in pain, responses to warmth and cold, menstrual blood, abdomen, pulse, and tongue.
Use etiology (L2) and cold environment (L8) to distinguish what acts, and the cycle (L9) to distinguish when it changes.
