Could a celery seed extract help prevent another stroke?
NCT ID NCT07230587
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 3 trial tests whether butylphthalide, a compound from celery seed, can improve long-term recovery in people who have had a minor ischemic stroke. 1,200 participants aged 40–80 will take either the drug or a placebo for 12 months. Researchers will measure survival, stroke recurrence, disability, new brain damage, and cognitive changes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- butylphthalide (NBP), a compound from celery seed
- What this could lead to
- If it works, this could provide a new long-term treatment to reduce disability, prevent recurrent strokes, and protect cognitive function after a minor stroke.
- What could go wrong
- This is a large Phase 3 trial, but butylphthalide is not yet proven for long-term use in minor stroke. The benefits may be modest, and side effects are possible. Results may not apply to all stroke types.
