Sharpleaf Galangal Fruit … Classic Formulas
Yi Zhi Ren · Fructus Alpiniae Oxyphyllae
Primary Actions
- Warms the Kidney and secures the lower burner - Yi Zhi Ren is used for frequent urination, enuresis, urinary dribbling, and deficiency-cold leakage.
- Warms the Spleen and stops diarrhea - it is especially suited to chronic cold-type loose stool or dawn diarrhea rooted in spleen-kidney weakness.
- Retains essence - traditional use includes spermatorrhea and seminal leakage when warming and astringing are both needed.
- Controls excessive salivation and cold middle-burner rebellion - it is valued for drooling, nausea, or vomiting that reflect cold deficiency rather than heat.
Classic Formulas
- Suo Quan Wan - classic lower-burner deficiency-cold formula pairing Yi Zhi Ren with Wu Yao and Shan Yao for frequent urination and enuresis.
- Spleen-warming diarrhea formulas pair Yi Zhi Ren with Bu Gu Zhi or Shan Yao when chronic cold-type diarrhea persists.
- Stomach-cold or saliva-controlling formulas combine it with Sha Ren, Chen Pi, or other warming digestive herbs when drooling, nausea, or cold indigestion accompany weakness.
Classical Text References
- Ben Cao Shi Yi and later materia medica describe Yi Zhi Ren as a pungent warm fruit that treats urinary dribbling, seminal leakage, vomiting, and excess salivation.
- Classical commentaries also warn that Yi Zhi Ren disperses as well as tonifies, so it should match deficiency-cold patterns rather than dry-heat or yin-deficient ones.
