Effectiveness and safety of XiaoBai granule and Losartan Potassium for the reduction of albuminuria in patients with Chronic Glomerulonephritis (CKD stage 1-2)：a multicenter, randomized, double-blind, controlled clinical trial
This multicenter, randomized, double-blind, controlled clinical trial demonstrates that combining XiaoBai granule with Losartan Potassium is safe and significantly more effective than Losartan Potassium alone in reducing albuminuria and improving renal function in patients with chronic glomerulonephritis (CKD stage 1-2).

For millions of people around the world, the kidneys work silently in the background, filtering waste from the blood and balancing fluids. When these organs are damaged by a condition called chronic glomerulonephritis, a type of long-term inflammation in the kidney's tiny filtering units, they begin to leak. This leakage allows protein, a vital building block of the body, to escape into the urine. In the early stages of this disease, patients often feel fine, but without intervention, the slow leak can eventually lead to total kidney failure. The standard medical approach to slowing this damage involves using drugs that relax the blood vessels inside the kidney to reduce pressure, much like turning down the water pressure on a leaking pipe. However, these medications can sometimes cause side effects, and for many patients, the protein loss continues despite treatment. This has led researchers to look for ways to strengthen the body's natural defenses alongside modern medicine, exploring whether ancient herbal remedies can offer a safer, more complete shield for the kidneys.
In a major clinical trial conducted across nine hospitals in Shanghai, a team of researchers set out to test exactly this idea. They focused on a specific group of patients with early-stage chronic glomerulonephritis, those whose kidneys were still functioning well enough to filter blood but were already showing signs of protein leakage. The study involved 160 adults who were randomly assigned to one of two groups. Everyone in the study received a standard dose of a common kidney-protecting medication known as losartan potassium. The difference lay in what they took alongside it. One group received a placebo, a substance designed to look and taste exactly like the herbal medicine but containing no active ingredients. The other group received a specific herbal formula called Xiao Bai granule. This mixture, developed by nephrologists at a traditional Chinese medicine hospital, combines eight different plant-based ingredients, including the root of the astragalus plant and the stamen of the lotus flower, which have been used for centuries to support kidney health and reduce inflammation.
The researchers followed these patients for six months, checking their progress at regular intervals. The primary goal was to see if adding the herbal granules to the standard medication could stop the protein from leaking into the urine more effectively than the medication alone. The results were clear and significant. By the end of the six-month period, the patients who took the combination of the herbal granules and the standard drug showed a much greater reduction in protein in their urine compared to those who took the standard drug and the placebo. In fact, the protein levels in the treatment group dropped steadily over time, while the levels in the control group actually crept slightly higher. Beyond just the numbers, the patients receiving the herbal treatment also reported feeling better. They experienced a noticeable improvement in common symptoms associated with kidney strain, such as fatigue, soreness in the lower back and knees, and a lack of appetite.
The study also looked deeper into the health of the kidney's tiny tubes, which are often the first to show signs of injury. The researchers measured specific markers in the urine that indicate damage to these tubes. They found that the group taking the herbal granules had a significant decrease in these damage markers, suggesting that the treatment was actively protecting the internal structure of the kidney. In contrast, the group on the standard medication alone saw these markers worsen slightly over the same period. This indicates that the herbal formula did more than just lower the pressure; it helped repair or preserve the delicate filtering machinery inside the organ. Crucially, the study found no increase in side effects or safety issues for the group taking the herbal combination. The patients tolerated the treatment well, with no new health problems arising from the addition of the herbal medicine.
This research provides a compelling piece of evidence that combining traditional herbal medicine with modern pharmaceuticals can offer a superior outcome for patients with early-stage kidney disease. While the standard medication alone helps, adding the Xiao Bai granules appears to accelerate the healing process, reduce protein loss more rapidly, and improve the patient's overall sense of well-being. The findings suggest that the specific blend of herbs works synergistically with the standard drug, perhaps by calming inflammation and reducing oxidative stress within the kidney tissue. Although the study was conducted in a specific region and involved a moderate number of participants, the consistency of the results over six months offers a strong signal for doctors and patients. It points toward a future where kidney care might not rely on a single type of medicine, but rather on a thoughtful integration of different medical traditions to protect the body's most vital filters.
