Indications: For individuals with below-average physical strength who tend to get fatigued easily, have cold extremities, reduced or excessive urine output, and sometimes thirst. It is applicable to the following conditions: lower limb pain, lumbago, numbness, blurred vision in the elderly, pruritus, dysuria, incomplete bladder emptying, nocturia, frequent urination, edema; it relieves symptoms associated with hypertension (stiff shoulders, heavy head, tinnitus) and mild urinary incontinence.
Prescription explanation: This is a traditional Chinese herbal formula used for nocturia and chronic lumbago. It is suitable for people who begin to worry about declining physical functions as they age. In Kampo medicine, there is the concept of the "kidney", which governs growth and reproduction. Aging weakens this function, leading to a state known as "kidney deficiency", which triggers discomforts such as urination disorders. Hachimi-jio-gan tonifies the function of the "kidney", warms the body, and regulates the balance of body fluid, thereby improving urination problems, lumbago and leg pain caused by aging.
