Ancient herb takes on PCOS: new hope for millions?
NCT ID NCT07603505
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a herbal extract from a Himalayan plant (Nepeta adenophyta) in 116 women with PCOS. Participants took either the herb, the standard drug metformin, or both for 4 months. The goal was to see if the herb could help restore regular menstrual cycles and improve metabolic health. This is an early-stage trial, so results are preliminary but could point to a new treatment option.
