Case: A woman in her thirties with persistent tiredness for several months. Difficulty getting up, poor appetite, cold sensation, delayed menstruation with pale menstrual blood. The tongue is pale and swollen with a white coating; the pulse is deep, thin, and weak. Symptoms worsen particularly during the rainy season.
1. Conventional pattern differentiation and treatment
Pattern: qi and blood deficiency (spleen–stomach weakness). Juzentaihoto / Hochuekkito. Points: Zusanli, Qihai, and Pishu. This conventional formulation does not explain why symptoms worsen in the rainy season through qi supplementation alone.
2. Mapping the case to the nine nine MLMN layers
| L1 Congenital foundations | A predisposition to spleen–stomach weakness (inherent vulnerability to dampness) |
|---|---|
| L3 Zang-fu | Deficiency of both spleen (transformation and transportation) and kidney (menstruation and cold sensation) |
| L4 Qi, blood, and body fluids | Alongside qi and blood deficiency, spleen deficiency generates internal dampness |
| L8 Environment | Record exposure to humidity, temperature, and living or working environments as input conditions for external dampness |
| L9 Temporal phase | The seasonal phase of the rainy season, a chronic course over several months, menstrual-cycle fluctuations, and reversibility after humidity decreases |
3. Comparative hypotheses within MLMN
Within this theoretical model, nourishing medicines given while dampness is present may aggravate it (“deficiency unable to accept supplementation”). The proposed sequence is first to transform dampness and awaken the spleen, then supplement once dampness has cleared. Even under the same label of qi and blood deficiency, the model considers whether addressing dampness before supplementation changes the outcome.
Separating environment such as humidity and temperature (L8) from the rainy season, cycles, and chronic course as temporal phases (L9) avoids confusing what acts with when symptoms worsen.
