Celery extract has been shown in animal studies to help prevent stroke, improve blood flow, and act to protect the brain and enhance energy production. In a human study of 30 patients with mild to moderate high blood pressure, celery seed extract standardized for 85% 3-n-butylphthalide (3nB) was given to the patients at a daily dose of 150 mg for 6 weeks. Blood pressure was monitored at weeks 3 and 6. There was a statistically significant decrease in both systolic blood pressure (SBP) and diastolic blood pressure (DBP) at weeks 3 and weeks 6 compared to baseline. A mean decrease of 8.2 mm Hg for systolic blood pressure was recorded after 6 weeks. There was also a mean decrease of 8.5 mm Hg for the patients’ diastolic blood pressure.
The authors concluded:
“The results from this pilot study suggest that celery seed extract may have clinically relevant blood pressure–lowering effects, indicating that additional clinical research is warranted.”
