Could a common herb ease rheumatoid arthritis?
NCT ID NCT07709312
First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This study investigates whether ginkgo biloba extract can improve outcomes for people with moderate to severe rheumatoid arthritis who are already on standard disease-modifying drugs. Participants take ginkgo biloba for 12 weeks, and researchers measure changes in inflammation markers like hsCRP and calprotectin, as well as joint pain and physical function. The goal is to see if this herbal supplement can help control the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ginkgo biloba leaf extract (120 mg)
- What this could lead to
- If it works, this could point toward a natural supplement to help manage rheumatoid arthritis alongside standard medications.
- What could go wrong
- This is a small, early-phase trial with only 50 participants, so results may not apply broadly. Ginkgo biloba can also cause side effects or interact with other drugs.
