What are the benefits and effects of Liuwei Dihuang Capsules?

Liuwei Dihuang Capsule primarily has the effect of nourishing yin and tonifying the kidney, and can be used to treat diseases caused by kidney yin deficiency. Liuwei Dihuang Capsule is a traditional Chinese medicine for nourishing kidney yin, made from six Chinese herbal medicines: Rehmanniae Radix Preparata, Cornus Fructus, Dioscoreae Rhizoma, Alismatis Rhizoma, Moutan Cortex, and Poria. It has the effect of nourishing yin and tonifying the kidney, and is clinically used to treat symptoms such as dizziness and tinnitus, soreness and weakness of the waist and knees, bone-steaming fever (a sensation of heat emanating from the bones), night sweats, and involuntary semen emission caused by kidney yin deficiency. The adverse reactions of Liuwei Dihuang Capsule are not yet clear, but it is not suitable for patients with colds and fever to take it, as it may aggravate the cold. During medication, patients should also avoid consuming food that is not easy to digest, as it may affect the efficacy of the medicine and hinder recovery. For patients with severe chronic diseases such as hypertension, heart disease, liver disease, diabetes, and kidney disease, as well as children, pregnant women, and lactating women, medication should be taken under the guidance of a physician. Before taking the medicine, patients should carefully read the instructions or provide a detailed description of their special allergy history, physical condition, underlying diseases, and recent medication history to the physician to exclude medication contraindications and avoid serious medication risks. If symptoms have not improved after 4 weeks of continuous medication, or if serious, persistent, or progressive symptoms occur during medication, patients should promptly consult a physician or seek medical attention.
