Effects of Nigella sativa Allelochemical Substances on Growth-Inhibiting Flixweed Compared With Wheat (Triticum aestivum)

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 dis...

BACKGROUND In previous studies, the relaxant, anticholinergic (functional antagonism) and antihistaminic effects of Nigella sativa have been demonstrated on guinea pig tracheal chains. To elucidate the other mechanisms responsible for the relaxant effect of this plant, its inhibitory effect on the calcium channel was examined in this study. RESULTS The inhibitory effects of both concentration...

For this reason, we observed the 2 months protection in...

objective: oxidative stress plays an important role in the etiology of diabetic complications. diabetes impairs hippocampus neurogenesis, synaptic plasticity, and learning. the aim of this study was to investigate the effects of hydroalcoholic extract of nigella sativa seed on oxidative stress in stz-induced diabetic rats' hippocampus. materials and methods: diabetes induced by 60 mg/kg st...

Six rare naturally occurring indazole-type alkaloids including two new compounds, 17-O-(β-d-glucopyranosyl)-4-O-methylnigellidine (1) and nigelanoid (2), and four known compounds (3-6) were isolated from a defatted extract of Nigella sativa (black cumin) seeds. 17-O-(β-d-Glucopyranosyl)-4-O-methylnigellidine (1) increased glucose consumption by liver hepatocytes (HepG2 cells) through activation...

in order to evaluation the effect of nigella sativa supplementation on performance, immune response and some of blood parameters, a total of 192 one day old ross 308 broilers were used in a completely randomize design with four treatments, four replicates and 12 observations in each replicate. treatments included the increasing levels of zero (control), 0.4, 0.8 and 1.2 percent nigella sativa. ...

in the previous studies the relaxant, anti-cholinergic (functional antagonism) and anti-histaminic effects of nigella sativa have been demonstrated on guinea pig tracheal chains. to elucidate the main substance responsible for the relaxant effect of this plant, the effect of thymoquinone, one of the main constituent of nigella sativa was examined in this study. the bronchodilatory effects of th...

Background and objectives: Nigella sativa is a delicate floral vegetable belonging to Ranunculaceae family. Thymoquinone (TQ) is the dominant active component in Nigella sativa seed oil which has a variety of pharmacological properties such as antioxidant, anticancer, anti-inflammatory and analgesic activities. However, TQ is a quinone derivative, which may le...
