NCT ID NCT07728695
First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time
Summary
This trial tests whether a custom-formulated, high-CBD hemp product can reduce pain in women with endometriosis, adenomyosis, or chronic pelvic inflammatory disease. Over 7 days, participants receive either the CBD product or a placebo. Researchers will measure how the body processes CBD and track changes in pain and inflammation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a custom-formulated, high-CBD hemp-derived product
- What this could lead to
- If it works, this could point toward a new, plant-based option for managing chronic gynecologic pain.
- What could go wrong
- This is an early-phase trial with only 60 participants and a short 7-day treatment period, so results may not apply broadly. CBD can cause side effects like drowsiness or digestive issues.
