Nigella sativa (thymoquinone)
Black seed (Nigella sativa) is a small dark seed of a plant in the Ranunculaceae family. The dried seeds and their oil are used mainly to relieve constipation, support gynecological health, reduce skin hyperpigmentation, ease headaches and rheumatic pain, and treat ear inflammation and tinnitus. While generally well tolerated, it can cause mild gastrointestinal upset or allergic reactions, and pregnant women should use it only under professional guidance.
