Black seed, also known as nigella sativa, has many potential health benefits supported by research studies. It may help treat type 2 diabetes, epilepsy, colon cancer, MRSA, heart attacks, breast cancer, brain cancer, leukemia, brain damage from lead, and oral cancer. The seed contains phytochemicals like thymoquinone that are anti-fungal, anti-cancer, beneficial for liver health, may help with weight loss and diabetes, and can treat infections like MRSA. Black seed oil may also benefit hair, skin, and insomnia when used consistently over time.
