How long does it take to take the effect of Shrinking Spring Capsule is related to the severity of the patient’s condition and cannot be generalized. Shrinking Spring Capsule is a common Chinese medicine, the efficacy of which is mainly to warm the kidneys and dispel cold, tonify the kidneys and reduce urination. It is mainly used clinically for frequent urination and nocturnal enuresis caused by bladder deficiency and cold. The main ingredients of this medicine are yam, puzzle nut and wu yao, which can reduce the water load of the body to a certain extent. This medicine is generally more effective, but because of the slow medicinal properties of proprietary Chinese medicine, it is usually effective for milder conditions for about 1 month. Some patients with more severe disease need to take it for about 3 months before the obvious effect can appear. In general, if the effect is not obvious after 1 month of taking the medicine, patients are advised to consult the urology department to rule out other diseases. In addition, patients with hypertension are advised to avoid taking the capsules as they may cause an increase in blood pressure and heart rate.
