Jin yin zi for night urine

 金櫻子 (Jīn Yīng Zǐ) — TCM explanation for night urination (nocturia) related to Kidney deficiency

TCM Nature & Functions

• Taste / Nature: Sour, astringent, neutral

• Meridians: Kidney, Bladder, Large Intestine

• Key Actions:

  • Astringes and stabilizes the Kidney

  • Secures Essence (精)

  • Reduces frequent urination, especially at night

  • Controls leakage (urine, semen, chronic diarrhea)

Night Urination (Nocturia) – TCM Pattern
金櫻子 is most suitable when nocturia is caused by:

• Kidney Qi deficiency

• Kidney Yang weakness

• Weak bladder control
  Typical signs:

• Frequent night urination, clear urine

• Weak lower back and knees

• Fatigue, cold limbs (if Yang deficiency)

• Possible urinary incontinence or dribbling

Why 金櫻子 Works

• Sour + astringent → tightens the Kidney gate

• Strengthens the Kidney’s ability to hold urine

• Improves bladder control without harsh drying

Common TCM Combinations for Night Urine

• 金櫻子 + 桑螵蛸 → strengthens bladder control

• 金櫻子 + 益智仁 → warms Kidney Yang, reduces nocturia

• 金櫻子 + 山茱萸 → tonifies Kidney & secures essence

• 金櫻子 + 芡实 → reinforces astringing effect

Important Usage Notes

• Best for deficiency-type nocturia, not for:

  • Damp-heat urinary infections

  • Painful or burning urination

• Avoid long-term use alone if there is strong coldness or severe Yang deficiency — combine with warming herbs

Simple Home Decoction (mild)

• 金櫻子 6–10g

• 芡实 10g

• 山药 12g
  Boil and drink once daily, preferably evening

TCM Summary

金櫻子 is a classic herb for night urination due to weak Kidney control, helping the Kidney “close the gate” and restore urinary stability.
