Diabetes

Diabetes mellitus results in severe metabolic imbalances and pathological changes in many tissues. Oxidative stress has been shown to play an important role in the etiology of diabetes and diabetic complications. Diabetics exhibit high-oxidative stress due to persistent and chronic hyperglycemia, thereby reducing the activity of the antioxidative defense system and thus promoting free radical generation. Several interactive pathogenetic mechanisms of diabetic peripheral neuropathy have been identified in both human and murine models and persistent hyperglycaemia has been regarded as a primary risk factor for neuropathy. Long-term hyperglycaemia can lead to subsequent enhanced oxidative stress, increased aldose reductase activity, and accumulation of advanced glycation endproducts (AGE). As a result, it could induce progressive damage to the peripheral sensory and autonomic nervous systems. To date, except for rigorous glycaemic control, there are few means to affect or slow the natural progression of diabetic peripheral neuropathy owing to limitations of the current and often inadequate drug therapy.

However, in a recent animal study, scientists found Nigella sativa and its pharmacologically active substance thymoquinone, affected blood glucose levels, and insulin. Furthermore, they suggested that the antioxidant activity of black seed may alleviate damage to b-cells in the pancreas. The study found less damage to tissues in diabetic animals treated with black seed and thymoquinone. The researchers concluded that the neuroprotective effects of thymoquinone and especially black seed are attributed to its direct and indirect antioxidant actions.
