Objective: To evaluate the efficacy of a standardized extract of celery seed, 150 mg/d, supplying 85% 3-n-butylphthalide (3nB) in mild to moderate hypertensive patients.
Study Design: A single-arm study of 30 mild to moderate hypertensive patients given the test medication following a 7-day wash out period. The primary clinical assessment was the effect on blood pressure at week 3 and week 6. Secondary measures were fasting blood levels of total cholesterol, LDL cholesterol, HDL cholesterol, VLDL cholesterol, free fatty acids, and serum electrolytes (i.e., sodium, potassium, calcium).
Results: There was statistically significant decrease in both systolic blood pressure (SBP) and diastolic blood pressure (DBP) at week 3 and week 6 compared to baseline. The change at week 6 for the SBP was 8.2 mmHg (SD=3.6, P<0.005) and for the DBP was 8.5 mmHG (SD=2.9, P<0.005).
Conclusions: 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.
