简要总结
Diabetes mellitus is a growing global concern with significant health and financial burdens. The Kingdom of Saudi Arabia is one of the world's top 10 countries with the highest diabetes prevalence. Strict blood glucose control is an important measure in the treatment of diabetes and prevention of its complications. The scientific community has recently shown a profound interest in the area of complementary and alternative medicine where a ton of research is being conducted. The primary focus of this field of research is subjecting many of the medicinal plants used in herbalism to the scientific methodology of testing. In order for these plants to be implemented in treatment protocols, their effect must be clearly proven and documented scientifically. This study aims to investigate the effect of daily consumption of black seed oil on the blood sugar levels of healthy adults.

盲法说明
Both participants and researchers involved directly in collecting data (ex. Measuring blood pressure or interviewing subjects) will be unaware of the allocation status and thus blinded. However, statistical analysts and those who will provide the participants with the intervention/placebo will be aware of the allocation status. All interventions (black seed oil and charcoal softgels) will be supplemented in neutral identical containers. Each participant will receive a container labeled with his or her specific identification code and containing the intervention for the arm to which he or she has been allocated.
