For these very important  reasons, scientists try their best to dissolve this problem ; once they try to reduce hyper lipidemia (all types of lipid) through regulation of diet , others try to use medications with or without diet regulation (3). However, medications used (for example statins ,nicotinic acid , lopid , tricor etc ……)have limited effects in reducing lipid level ,since it needs long time , can not be used in all conditions, besides, they are not free of risks as a side effects .

Therefore , in the last decades , scientists turned their attention toward using  harmless herbs since, these herbs posses pharmacological principles. Besides , traditionally these herbs are widely utilized to improve human health through curing numerous diseases. Example for these herbs are fenugreek & nigella sativa(4)(5)(6) .

Recently , animal studies have shown that extract of N.sativa have many therapeutic effects such as gastrotection, anti malignant effect(11) , & anti oxidant(12).

The black seeds have different constituents such mucilage , crude fiber , alkaloid , sugar resins , saponins & proteins(8). Besides , they have high content of unsaturated fatty acids(13).
