NCT ID NCT04552600
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a herbal extract called Nuvastatic in 100 adults with type 2 diabetes who have early-stage diabetic retinopathy (eye damage). The goal was to see if it can safely slow the disease and improve vision. Participants received either the extract or a placebo, and researchers measured changes in retinal thickness, protein markers, and visual acuity.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Nuvastatic (standardized Orthosiphon Stamineus extract, also known as Lanctos 75)
What this could lead to
If it works, this could point toward a new herbal-based treatment to slow or manage diabetic retinopathy, potentially reducing vision loss.
What could go wrong
This is an early-phase trial with only 100 participants, so results may not be conclusive. The herbal extract may not prove effective or safe in larger studies.
