Medicinal Value of Black cumin (Nigella sativa):


Black cumin seed has been used for centuries to treat respiratory and digestive problems, parasites, and inflammation. In ancient times, it was a remedy for a variety of health conditions including, colds, infections, headaches, and toothaches. Black cumin was also used as a remedy for skin diseases, dry skin, dandruff and wounds.
Many herbalists in current times embrace the healing properties of black cumin seed extract. For example, the extract is sometimes used externally to treat such skin care problems as psoriasis, eczema, and dry skin, and internally to treat stomach problems, respiratory ailments, and allergies, as well as to improve circulation and the immune system. In recent years, the extract has been the subject of immune system research.
One reason that is often given for the medicinal value of black cumin seed extract is its richness in polyunsaturated fatty acids, which help to produce prostaglandin E1. Prostaglandin E1 has many functions in the body, particularly in relation to the immune system, sugar metabolism, skin infections, and blood clots. It is also believed to protect the stomach lining.
Experts point out that the medicinal value may be provided by a unique and mysterious synergy (combined action) between the multitude of compounds present in the seeds. In addition, the extract, which is more concentrated than the seeds alone, is said to have greater healing power. A study at Cairo University in Eqypt showed a boost in antibacterial activity when the extract was used in combination with antibiotics such as streptomycin and gentamicin. In the same study, it showed additional antibacterial function in combination with erythromycin, tobramycin, doxycycline, and ampicillin, to kill E. coli and the pathogenic yeast, Candida albicans.
