Black Seed Oil May Help Improve Blood Pressure

Black seed oil contains thymoquinone, which is an antioxidant and anti-inflammatory compound. A recent study suggests that supplementation with black seed oil may help improve blood pressure.

Nineteen adults with a resting blood pressure between SBP 135-159/ DBP 85-99 participated in the study. They took a capsule containing 15 mg of thymoquinone black seed oil daily for 42 days. After a three-week washout period, they took a placebo capsule daily for 42 days. Resting blood pressure measurements were taken daily.

While taking the black seed oil supplement, participants’ mean systolic blood pressure decreased by 11.2%, from 143.5 mm Hg to 127.3 mm Hg. Mean diastolic blood pressure decreased by 12.2%, from 90.7 mm Hg to 79.6 mm Hg.

The study was conducted by researchers from Natural Medicine of Stillwater. It was published on March 30, 2020 in the journal Food Science & Nutrition Research.
