Abstract:

In the present work, the antihypertensive effects of celery seed extract (Apium graveolens) with active ingredients, such as 3-n-butylphthalide, were studied as a drug supplement in the treatment of hypertension. This study was a randomized, triple-blind, placebo-controlled, cross-over clinical trial. Fifty-two patients were divided into two groups (celery and placebo) and completed the two-step clinical trial. Four celery seed extract capsules (totally 1.34 g per day) or 4 placebo capsules per day were administered to the patients during a 4-week clinical trial. The blood pressure was assessed using a 24-hr ambulatory blood pressure monitoring method. In celery group, systolic blood pressure changed from 141.2 ± 5.91 to 130.0 ± 4.38 mmHg (p < .001) while diastolic blood pressure changed from 92.2 ± 5.74 to 84.2 ± 4.87 mmHg (p < .001). Moreover, the mean arterial blood pressure changed from 108.5 ± 5.76 to 99.5 ± 4.66 mmHg (p < .001), and pulse pressure decreased from 49.0 ± 6.21 to 45.8 ± 6.01 mmHg (p < .01). However, no significant changes were observed in placebo group in terms of the above-mentioned parameters (p > .05). Furthermore, no significant side effect was reported in the celery group, compared to the placebo group (p > .05). The results were promising and indicated the therapeutic effects of celery seed extract as a supplement in the management of hypertension.
