Antipsoriatic activity and cytotoxicity of ethanolic extract of Nigella sativa seeds.



Nigella sativa Linn (Ranunculaceae) is popularly known as black cumin with a wide spectrum of pharmacological activities including anti-inflammatory, antibacterial, antifungal and antihelmenthic. The seeds are externally applied for eruptions of skin. The seeds are used traditionally for psoriasis tropicus with general pain and eruption of patches.


The ethanolic extract of Nigella sativa seeds were evaluated for antipsoriatic activity.


The screening of antipsoriatic activity of 95% of ethanolic extract of Nigella sativa seeds by using mouse tail model for psoriasis and in vitro antipsoriatic activity was carried out by SRB Assay using HaCaT human keratinocyte cell lines.


The ethanolic extract of Nigella sativa seeds extract produced a significant epidermal differentiation, from its degree of orthokeratosis (71.36±2.64) when compared to the negative control (17.30±4.09%). This was equivalent to the effect of the standard positive control, tazarotene (0.1%) gel, which showed a (90.03±2.00%) degree of orthokeratosis. The 95% ethanolic extract of Nigella sativa shown IC50 239 μg/ml, with good antiproliferant activity compared to Asiaticoside as positive control which showed potent activity with IC50 value of 20.13 μg/ml.


The ethanolic extract of Nigella sativa seeds also showed increase in relative epidermal thickness when compared to control group by confirming its traditional use in psoriasis treatment.

Effect of Nigella sativa (black seed) on subjective feeling in patients with allergic diseases.


Nigella sativa (black seed) is an important medicinal herb. In many Arabian, Asian and African countries, black seed oil is used as a natural remedy for a wide range of diseases, including various allergies. The plant’s mechanism of action is still largely unknown. Due to the lack of study data on its efficacy in allergies, four studies on the clinical efficacy of Nigella sativa in allergic diseases are presented. In these studies, a total of 152 patients with allergic diseases (allergic rhinitis, bronchial asthma, atopic eczema) were treated with Nigella sativa oil, given in capsules at a dose of 40 to 80 mg/kg/day. The patients scored the subjective severity of target symptoms using a predefined scale. The following laboratory parameters were investigated: IgE, eosinophil count, endogenous cortisol in plasma and urine, ACTH, triglycerides, total cholesterol, LDL and HDL cholesterol and lymphocyte subpopulations. The score of subjective feeling decreased over the course of treatment with black seed oil in all four studies. A slight decrease in plasma triglycerides and a discrete increase in HDL cholesterol occurred while the lymphocyte subpopulations, endogenous cortisol levels and ACTH release remained unchanged. Black seed oil therefore proved to be an effective adjuvant for the treatment of allergic diseases.
