Black seed – also known as black cumin – comes from the Nigella sativa plant, and it’s been used for centuries in many cultures for its healing properties. It’s a rich source of essential fatty acids, amino acids, and nutrients that help to boost the immune system. When combined with Echinacea and goldenseal supplements, the goldenseal and echinacea components enhance the black cumin to create a more powerful product to help create better overall health.
