The main active ingredient within oil sourced from Nigella sativa seeds is thymoquinone, a powerful antioxidant. In a non-randomized clinical study published in the journal Food Science and Nutrition Research, the branded black seed oil, with a free fatty acid level of 1.8%, lowered blood pressure and increased heart rates in otherwise healthy individuals.
“Almost a third of the adult population in America experiences hypertension, and natural products, including Nigella sativa oil, have long been considered as a therapeutic remedy in many traditional medicine practices across the world,” Morrsi Zelkha, CEO of TriNutra, said. “This study demonstrated how ThymoQuin can help provide significant improvement towards healthy blood circulation measurements, which has not been seen from other more common varieties of black seed oil.”
The study followed 19 volunteers with a baseline resting blood pressure measuring between 135-159 systolic and 85-99 diastolic blood pressure for 108 days. All subjects were given 500 mg of ThymoQuin 3%, containing a total of 15 mg thymoquinone, for the first 42 days, followed by a washout period of three weeks. They were then administered a placebo for six weeks until the study ended 108 days later. Blood pressure was measured daily throughout the study. During the six-week treatment period, subjects experienced mean decreases of 11.2% in systolic blood pressure, and 12.2% in diastolic blood pressure. Not until after the washout period did participants’ blood pressure begin to increase and the treatment effects begin diminishing, researchers said. ThymoQuin’s effect was rapid, researchers added, after seeing significant decreases in the population’s blood pressure after just two days of supplementation.
“The research supporting black seed oil supplementation for multiple facets of health continues to grow,” Chris Holland, VP of sales at Barrington Nutritionals, said. “The results of this study add to the arsenal of over 50 additional clinical trials demonstrating the benefits of black seed oil, it’s no wonder this powerful ingredient has been gaining increased awareness and interest over the last few years.”
