Support healthy blood pressure levels naturally with Black Cumin Seed Oil by Amazing Herbs. Each easy-to-swallow softgel supplies 500 milligrams of the oil, cold-pressed to preserve 100% of the active components. The active component is thymoquinone, a bioactive phytochemical that prevents oxidative stress and (potentially) cancer. The cold-pressed extraction process yields 95% thymoquinone per serving. Black cumin seed oil also supplies essential fatty acids (EFAs), which raise good cholesterol, lower bad cholesterol, and scavenge your body for free radicals.
