In Arabo-Islamic culture, black cumin has been prescribed for various ailments, including fever, asthma, chronic headaches, diabetes, digestion, back pain, infections, and rheumatism.
In Arabic culture, black cumin is known as Habbatul barakah, the seed of blessing. In fact, since its rise in popularity in the seventh century, it is still regarded as important family medicine and the oil that is most often used medicinally.
Ibn Sina, also known as Avicenna (980–1037 AD), mentions it in his Canon of Medicine: “that which stimulates the body’s energy and helps recover from fatigue or dispiritedness.” The spice is also believed to be good for purification and detoxification of the body; reduction of mucous and improved lung function; fever, coughs, and colds; toothache; headache; skin diseases and wound treatments; intestinal parasites and worms; and poisonous bites and stings.
While researching my book on Natural Solutions for Diabetes, I studied all the major herbs to treat diabetes in Ayurveda and Traditional Chinese Medicine. Black cumin is not a herb useful for diabetes treatment in these prominent herbal medicine systems.
Black cumin is an important medicinal herb, but scientific evidence does not support the historical claims behind the antidiabetic properties of this herb.
