For centuries, the Black Seed herb and oil has been used by millions of people in Asia, Middle East, and Africa to support their health. An aromatic spice, similar looking to sesame seed except black in color, it has been traditionally used for a variety of conditions and treatments related to respiratory health, stomach and intestinal health, kidney and liver function, circulatory and immune system support, and for general overall well-being. Black Seed is also known as Black Cumin, Black Caraway Seed, Habbatul Baraka (the Blessed Seed), and by its botanical name "Nigella Sativa". This is the first in-depth book that covers its history of use from Biblical times up to the modern day with excerpts from research studies conducted throughout the world.
