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 petiole, 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 reproduces with itself and Nigella sativa and its black seed are known by other names, varying between places. Some call it black caraway, others call it black cumin (Kalonji), or even coriander seeds. In English, the Nigella sativa plant is commonly referred to as "Love in a Mist". Nevertheless, this is Nigella sativa, which has been known and used from ancient times and is also known in Persian as Shonaiz.
The most pertinent point to be made about black seed is that it should be regarded as part of an overall holistic approach to health and ideally should be incorporated into one's everyday lifestyle. In this way, the many nutritional and healing properties contained in the seed can help build the body's immune system over time, supplying it with the optimum resources it needs to help prevent and fight illness.
