Herbal supplement fails to show clear benefit in optic neuritis pilot
NCT ID NCT02976766
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This small pilot study tested whether adding gypenosides (a herbal supplement) to standard steroid treatment could help protect the nerve at the back of the eye in adults having their first episode of acute optic neuritis. Ten participants were enrolled, but the study was stopped early. The main goal was to measure nerve thickness in the affected eye after six months.
