Black cumin seeds, also known as Nigella sativa, are small, dark brown or black seeds with a slightly nutty flavor. They have been used in traditional medicine for centuries, and are now gaining popularity in Western cultures for their health benefits.

Black cumin seeds are a good source of fiber, protein, and iron. They also contain antioxidants, such as thymoquinone, which have been shown to have anti-inflammatory and antimicrobial properties.

Black cumin seeds are generally safe for most people to consume. However, they may cause side effects such as nausea, vomiting, and diarrhea in some people. They should also be avoided by pregnant women and breastfeeding women.
