Case: A woman in her sixties with a floating sensation of dizziness, tinnitus, low-back weakness, cold feet, and easy fatigue. The tongue is pale and swollen; the pulse is deep and thin.
1. Conventional pattern differentiation and treatment
Classical theory may organize this as kidney deficiency (insufficient kidney essence) or qi and blood deficiency, considering kidney supplementation or points such as Shenshu, Taixi, and Baihui. However, the nature of dizziness or tinnitus alone cannot establish a pattern or treatment method.
2. Mapping the case to the nine nine MLMN layers
| L1 Congenital foundations | Aging: gradual depletion of congenital kidney essence at the foundational level |
|---|---|
| L3 Zang-fu | Liver blood deficiency alongside the kidney component (insufficient nourishment of the head associated with the floating sensation) |
| L7 Sanjiao | An interpretive hypothesis within classical theory linking difficulty in clear yang ascending to the upper jiao with the floating sensation |
| Interlayer mechanism (mingmen fire / ministerial fire) | A candidate mechanism connecting aging and long-term foundations in L1, changes in kidney function in L3, and insufficient warming in L4. Declining mingmen or ministerial fire is an interpretation examined across several findings, not an original observation. |
| L9 Temporal phase | Record onset, speed of progression, recurrence, fixation, relationship to aging, and time until a treatment response |
3. Comparative hypotheses within MLMN
MLMN does not place deficient mingmen fire or declining ministerial fire in an independent layer. It adds them as candidate pathways from aging and long-term foundations to insufficient warming. This provides a point of comparison between simple nourishment and combined yin–yang supplementation, but interpreting floating dizziness as a deficiency pattern and considering treatment require other findings, contradictory evidence, and modern medical assessment.
Even within “kidney deficiency,” mingmen fire and ministerial fire are treated as hypotheses connecting layers such as L1, L3, and L4, not as layer names.
