Unusual diseases can defy conventional understanding. When relying solely on standard treatments, results may fail. Here is a documented case:
In mid-spring, the mother of Wang Danwen (a member of my clan) suddenly developed severe symptoms: extreme thirst, mental confusion, sudden dizziness, profuse sweating, a body burning “like fire,” and near-delirium.
First Treatment Attempt:
- Diagnosis by the patient’s brother (a scholar-physician): “Yangming Fever Syndrome” (a heat-related condition in Traditional Chinese Medicine).
- Prescription: Baihu Decoction ( “White Tiger Decoction”) with Shigao (gypsum, 37g by ancient measurement).
- Result: Fever persisted.
Second Treatment Attempt:
- Neighbor Li (another scholar-physician) prescribed Chengqi Decoction (“Qi-Regulating Decoction,” a purgative formula).
- Effect: Slight improvement in bowel movements, but fever remained.
Zui Hua Chuang Medical Cases Chapter 59
Third Evaluation:
- Wang Danwen requested my assessment.
- Pulse diagnosis: Deep and rapid pulse (Chen-Shu pulse), indicating Yin deficiency with excessive fire (internal heat due to bodily fluid depletion) and severe intestinal dryness.
- Conclusion: “No physical blockage exists—this is virtual fire disturbing the mind. Purgatives are ineffective; cooling methods are required.”
- Prescription: Dihuang Decoction (“Rehmannia Decoction”) combined with Shanzhi ( gardenia fruit) and Sanhuang ( Huangqin /baical skullcap, Huanglian /coptis root, Huangbai /cork tree bark).
- Result: Mental clarity improved slightly, but fever persisted.
Turning Point:
- A heavy snow fell overnight.
- At dawn, the patient demanded to eat snow. Her family initially refused, fearing harm to her elderly body.
- While her son was away, she crawled outside and consumed approximately three bowls of unheated snow.
- Immediate effect: “My mind cleared instantly.” She ate more snow, returned to bed, and by evening, her fever broke. She rose the next day and fully recovered within three days.
Physician’s Reflection:
- Medications failed, yet natural snow cured the condition.
- Explanation: Snow’s innate Yin-cold properties (unprocessed by fire) provided cooling power surpassing medicinal formulas by “ten thousandfold.”
- Note: This method appears in no medical text, and physicians would never dare prescribe it.
Key Terms Clarification:
- Baihu Decoction/Chengqi Decoction/Dihuang Decoction: Classic formulas from Shanghan Lun (Treatise on Cold Damage Disorders, a foundational TCM text).
- Sanhuang (“Three Yellows”): A combination of three bitter herbs used to clear heat.
- Scholar-physicians: Educated individuals (often trained in classical texts) who practiced medicine in historical China.
This case illustrates how nature occasionally offers solutions beyond medical orthodoxy—but such miracles depend on rare circumstances.
