Huangkui capsule is not a hormone, it is a proprietary Chinese medicine. In clinical practice, many nephritis have urine protein, such as chronic nephritis, and urine protein is very much like barbed iron ball, which will cause kidney damage in the process of losing through the kidney, so it is very important for patients with nephritis to control the amount of urine protein. The main western drugs used clinically to reduce urine protein are valsartan capsules and perindopril tablets, while the more commonly used Chinese medicine is Huangkui capsules. Huangkui capsule has the effect of repairing the filtration membrane of the kidney, which can reduce the amount of urine protein, therefore, it is widely used in patients with chronic nephritis. However, it should be emphasized that this drug is only a supplementary treatment for chronic nephritis, not a core treatment. The core treatment also needs to improve the microcirculation of the kidneys, control blood pressure and treat with hormones when necessary.
