An annual herbaceous plant, Black Cumin Seed (botanical name is Nigella
sativa L.), or Black Seed for short, is believed to be
indigenous to the Mediterranean region but has been cultivated into
other parts of the world including the Arabian peninsula, northern
Africa and parts of Asia. The plant has no relation to the common
kitchen herb, cumin.
Tiny and hairy, being no more than 3mm in length, black seed originates
from the common fennel flower plant (Nigella sativa) of the buttercup
(Ranunculaceae) family. Nigella sativa is sometimes mistakenly confused
with the fennel herb plant (Foeniculum vulgare).
The plant has finely divided foliage and pale bluish purple or white
flowers. The flowers grow terminally on its branches while the leaves
grow opposite each other in pairs, on either side of the stem. Its lower
leaves are small and petioled, and the upper leaves are long (6-10cm).
The stalk of the plant reaches a height of twelve to eighteen inches as
its fruit, the black seed, matures.
Nigella sativa is bisexual and forms a fruit capsule which consists of
many white triagonal seeds. Once the fruit capsule has matured, it opens
up and the seeds contained within are exposed to the air, becoming black
in color (black seeds).
Nigella sativa and its black seed are known by other names, varying
between places. Some call it Black caraway, "Habbat al
barakah", and "Habbat sawda", others call it black cumin
(kalounji), onion seeds or even coriander seeds. In English, the Nigella
sativa plant is commonly referred to as "Black Cumin".
Nevertheless, this is Nigella sativa, which has been known and used from
ancient times and is also known in Persian as Shonaiz.

Black
Cumin (Nigella sativa) was discovered in Tutankhamen`s tomb, implying that
it played an important role in ancient Egyptian practices. Although its exact
role in Egyptian culture is not known, we do know that items entombed with a
king were carefully selected to assist him in the afterlife.
The earliest written reference to black seed is found in the book of Isaiah in the Old Testament. Isaiah contrasts the reaping of black cumin with wheat: For the black cumin is not threshed with a threshing sledge, nor is a cart wheel rolled over the cumin, but the black cumin is beaten out with a stick, and the cumin with a rod. (Isaiah 28:25,27 NKJV).
Easton's
Bible Dictionary clarifies that the Hebrew word for black cumin,
"ketsah," refers to "without doubt the Nigella sativa, a small
annual of the order Ranunculaceae which grows wild in the Mediterranean
countries, and is cultivated in Egypt and Syria for its seed."
Dioscoredes, a Greek physician of the 1st century, recorded that black seeds
were taken to treat headaches, nasal congestion, toothache, and intestinal
worms. They were also used, he reported, as a diuretic to promote menstruation
and increase milk production.
The Muslim scholar al-Biruni (973-1048), who composed a treatise on the early
origins of Indian and Chinese drugs, mentions that the black seed is a kind of
grain called alwanak in the Sigzi dialect. Later, this was confirmed by Suhar
Bakht who explained it to be habb-i-Sajzi (viz. Sigzi grains). This reference to
black seed as "grains" points to the seed's possible nutritional use
during the tenth and eleventh centuries.
In the Greco-Arab/Unani-Tibb system of medicine, which originated from
Hippocrates, his contemporary Galen and Ibn Sina, black seed has been regarded
as a valuable remedy in hepatic and digestive disorders and has been described
as a stimulant in a variety of conditions, ascribed to an imbalance of cold
humors.
Ibn Sina (980-1037), most famous for his volumes called "The Canon of
Medicine," regarded by many as the most famous book in the history of
medicine, East or West, refers to black seed as the seed "that stimulates
the body's energy and helps recovery from fatigue or dispiritedness."
Black seed is also included in the list of natural drugs of Al-Tibb al-N abawi,
and, according to tradition, "Hold onto the use of the black seed for in it
is healing for all illnesses except death." This prophetic reference in
describing black seed as "having a healing for all illnesses" is not
exaggerated as it at first appears. Recent research has provided evidence
which indicates that black seed contains an ability to significantly boost the
human immune system - if taken over time. The prophetic phrase, "hold onto
the use of the seed," also emphasizes consistent usage of the seed.
Black seed has been traditionally used in the Middle and Far
East countries for centuries to treat ailments including bronchial asthma and
bronchitis, rheumatism and related inflammatory diseases, to increase milk
production in nursing mothers, to treat digestive disturbances, to support the
body's immune system, to promote digestion and elimination, and to fight
parasitic infestation. Its oil has been used to treat skin conditions such as
eczema and boils and is used topically to treat cold symptoms.
The many uses of black seed has earned for this ancient herb the Arabic
approbation habbatul barakah, meaning "the seed of blessing."

Black Cumin (Nigella sativa) Seed is rich in nutritional values.
Monosaccharides (single molecule sugars) in the form of glucose, rhamnose, xylose, and arabinose are found in the black seed.
The Black Cumin (Nigella sativa) Seed contains a non-starch polysaccharide component which is a useful source of dietary fiber.
It is rich in fatty acids, particularly the unsaturated and essential fatty acids (Linoleic and Linolenic acid). The EFAs, consisting of alpha-Linolenic acid (omega-3) and Linoleic acid (omega-6), are substances that cannot be manufactured in the body, and thus must be taken in as supplements or through high-EFA foods.
Fifteen amino acids make up the protein content of the Black Cumin (Nigella sativa) Seed, including eight of the nine essential amino acids. Essential amino acids cannot be synthesized within our body in sufficient quantities and are thus required from our diet.
Black seed contains Arginine which is essential for infant growth.
Chemical analysis has further revealed that the Black Cumin (Nigella sativa) Seed contains carotene, which is converted by the liver into vitamin A.
The Black Cumin (Nigella sativa) Seed is also a source of calcium, iron, sodium, and potassium. Required only in small amounts by the body, these elements' main function is to act as essential cofactors in various enzyme functions.
