About This Formula
Traditional Chinese Medicine background and properties
Formula Description
A classical three-herb formula used to warm the Kidneys and help the Bladder hold urine properly. It is commonly used for frequent urination, bedwetting in children, and nighttime urination caused by coldness and weakness in the lower body.

TCM Patterns
In TCM, symptoms don't appear randomly — they cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Suo Quan Wan is traditionally associated with these specific patterns.
The following describes this formula's classification within Traditional Chinese Medicine theory and is provided for educational purposes only.
Why Suo Quan Wan addresses this pattern
When Kidney Yang is insufficient, it cannot warm and support the Bladder's function of storing urine. The Bladder, which is the exterior partner of the Kidney, relies on Kidney Yang for its Qi transformation and holding capacity. Without adequate warmth, the lower body becomes cold and the Bladder loses its ability to restrain urine, leading to frequent, clear urination or involuntary leakage. Suo Quan Wan directly targets this mechanism: Yi Zhi Ren warms Kidney Yang and astringes, Wu Yao disperses the accumulated cold and restores Qi movement, and Shan Yao nourishes the Kidney foundation. The formula is particularly well suited to milder Kidney Yang deficiency focused on urinary symptoms, rather than severe Yang collapse with generalized coldness.
A practitioner would look for one or more of these signs
Frequent, clear, copious urination, especially at night
Bedwetting or involuntary urination during sleep
Inability to hold urine, dribbling after urination
Cold extremities, especially cold lower body
Soreness and weakness of the lower back and knees
Fatigue and low spirits, pale complexion
Why Suo Quan Wan addresses this pattern
This is the primary classical pattern for Suo Quan Wan. The Bladder is described as the 'reservoir of fluids,' responsible for temporarily storing urine and releasing it under the control of Kidney Qi. When cold settles in the Bladder due to underlying Kidney Yang weakness, the Bladder's 'gate' can no longer close properly. The result is urinary frequency or outright loss of urinary control. The classical text describes this as 'Bladder deficiency cold, frequent urination or ceaseless enuresis.' Yi Zhi Ren warms the Kidney to restore its governance over the Bladder, Wu Yao specifically eliminates cold Qi from the Bladder region and promotes normal Qi transformation, and Shan Yao supports Kidney-Spleen consolidation. The formula name itself, 'Shut the Sluice,' conveys the goal: to close the floodgate that cold has left open.
A practitioner would look for one or more of these signs
Frequent, clear urination that may reach many times per day and night
Enuresis (bedwetting), especially common in children
Stress incontinence, urine leaking with coughing or sneezing
Waking multiple times at night to urinate
How It Addresses the Root Cause
The Kidneys in TCM govern water metabolism and control the opening and closing of the lower orifices. The Bladder, as the Kidney's paired organ, stores and excretes urine, but only when the Kidney's Qi transformation function (气化 qì huà) gives it the 'signal' to hold or release. When Kidney Yang becomes deficient and Cold settles in the lower body, this Qi transformation breaks down. The Bladder loses its ability to properly restrain urine, much like a gate whose latch has frozen and can no longer hold shut.
Without sufficient Kidney Yang warmth, fluids pass through the Bladder unchecked, leading to frequent, clear, copious urination during the day and involuntary bed-wetting at night. The body may also show other signs of Yang deficiency and internal Cold: cold limbs, fatigue, a pale tongue with white coating, and a deep, weak pulse. In children, the Kidneys are constitutionally immature, making them especially prone to this pattern, which is why classical texts note this formula is "especially effective for children."
The Spleen also plays a supporting role: it governs the transport and transformation of fluids. When both the Spleen and Kidney are weak, the body's overall capacity to manage water metabolism deteriorates, compounding the problem of uncontrolled urination.
