About Black Seed Oil
Black seed oil (Nigella sativa) contains thymoquinone as the primary active compound. Multiple meta-analyses support clinical benefits: Daryabeygi-Khotbehsara et al. (2017) found significant reduction in fasting blood glucose and total cholesterol; Sahebkar et al. (2016) confirmed lipid-lowering effects; Mousavi et al. (2018) showed blood pressure reduction. Also has anti-inflammatory and antioxidant properties demonstrated in RCTs. One of the more evidence-backed herbal oils. Generally well tolerated; may interact with blood thinners and diabetes medications.
