About This Herb
Traditional Chinese Medicine background and properties
Herb Description
Euryale seed is a gentle, food-grade herb that has been used in Chinese medicine for over 2,000 years to support digestive and urinary health. It strengthens the Spleen and Kidneys, helping with chronic loose stools, frequent urination, and excessive vaginal discharge. Often called 'chicken-head rice,' it is mild enough for daily use in soups and porridges, earning its reputation as the 'water ginseng.'

- Secures the Kidneys and Stops Vaginal Discharge
How These Actions Work
'Benefits the Kidneys and secures essence' means Qian Shi strengthens the Kidneys' ability to hold and store vital substances. In TCM, the Kidneys are responsible for storing 'essence' (jīng), which governs reproduction, growth, and urinary control. When the Kidneys are weak, essence and fluids can leak out, causing problems like involuntary seminal emission, frequent urination, or bedwetting. Qian Shi's astringent taste gives it a binding, tightening quality that helps 'lock in' these substances. This is why it is so commonly used for men with involuntary seminal loss and for anyone with excessive nighttime urination.
'Tonifies the Spleen and stops diarrhoea' refers to Qian Shi's ability to strengthen digestive function. In TCM, the Spleen is the central organ of digestion, responsible for transforming food and transporting nutrients. When the Spleen is weak, it cannot properly manage fluids, leading to loose stools or chronic diarrhoea. Qian Shi's sweet taste nourishes the Spleen, while its astringent nature firms up the intestines. This makes it especially useful for prolonged diarrhoea caused by weak digestion rather than by infection.
'Eliminates dampness and stops vaginal discharge' means Qian Shi addresses excessive vaginal discharge (known as 'dai xia' in TCM). By strengthening both the Spleen (which controls dampness) and the Kidneys (which govern the lower body), Qian Shi tackles the root cause of abnormal discharge. Its astringent quality then directly reduces the leakage itself. This dual action of addressing the root deficiency while also providing symptomatic relief makes it a go-to herb for both clear/white discharge from cold-deficiency and yellow discharge from dampness-heat (when combined with heat-clearing herbs).
Patterns Addressed
In TCM, symptoms cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Qian Shi is traditionally associated with these specific patterns.
The following describes this herb's classification within Traditional Chinese Medicine theory and is provided for educational purposes only.
Why Qian Shi addresses this pattern
When the Kidneys lack sufficient Qi, they lose their ability to 'hold' and store essence and fluids. This leads to leakage of vital substances downward. Qian Shi enters the Kidney channel and its astringent taste directly addresses this failure to contain. Its sweet taste gently tonifies the Kidney Qi that is deficient. Together, these properties restore the Kidneys' grasping and storing function, which is why Qian Shi is a primary herb for seminal emission, frequent urination, and urinary incontinence caused by Kidney Qi weakness.
A practitioner would look for one or more of these signs
Especially nighttime urination
Or dribbling after urination
With involuntary seminal loss
Dull, weak ache in the lower back and knees
Why Qian Shi addresses this pattern
Spleen Qi Deficiency means the digestive system is too weak to properly transform food and manage fluids, allowing dampness to accumulate and stools to become loose. Qian Shi's sweet taste directly nourishes Spleen Qi, while its astringent quality firms up the intestines and reduces fluid leakage into the bowel. Crucially, classical sources note that Qian Shi can eliminate dampness without being overly drying, making it ideal for the Spleen, which is harmed by both excess dampness and excess dryness.
A practitioner would look for one or more of these signs
Prolonged loose stools that do not resolve
Reduced desire to eat
Tiredness after eating
Abdominal distension after meals
Why Qian Shi addresses this pattern
When both the Spleen and Kidneys are deficient, the body loses control over fluids in multiple ways simultaneously: chronic diarrhoea from Spleen weakness, urinary leakage from Kidney weakness, and excessive vaginal discharge from the combined failure of both organs to manage dampness in the lower body. Qian Shi is uniquely suited to this pattern because it enters both the Spleen and Kidney channels and addresses both organs at once. Classical texts praise it for being able to tonify without being cloying and to astringe without being overly drying, making it safe for long-term use in this dual-deficiency pattern.
A practitioner would look for one or more of these signs
Clear or white, thin discharge in large amounts
Watery stools with undigested food
Copious, pale urine
General weakness and lack of vitality
