Could a herbal tablet protect kidneys in diabetes?
NCT ID NCT01068041
First seen Jun 27, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
This study tested a plant-based tablet called PH3 in 100 adults with diabetic nephropathy (kidney damage from diabetes). The goal was to see if PH3 can safely reduce protein in the urine, a sign of kidney stress, over 24 weeks. Researchers also looked at the best dose to use in future studies.
