Ancient herbs take on diabetic kidney disease: new trial launches
NCT ID NCT07657351
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study will test whether adding a traditional Chinese herbal formula (DKD-1) to standard care can improve kidney function in people with diabetic kidney disease. Sixty-six adults with type 2 diabetes and moderate-to-severe chronic kidney disease will be randomly assigned to receive either standard care alone or standard care plus the herbal formula for 12 weeks. Researchers will measure changes in kidney function, blood sugar control, and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Chinese herbal formula DKD-1 (Astragalus, Salvia, Chinese yam, Poria, Moutan, Schisandra, Smilax)
- What this could lead to
- If it works, this could point toward a safe herbal supplement that helps protect kidney function in people with diabetic kidney disease.
- What could go wrong
- This is a very small, early pilot study with only 66 people over 12 weeks. The results may not be strong enough to recommend the treatment, and herbal formulas can vary in quality and purity.
