Maintain Blood Pressure and Promote Immunity

According to research, persons with moderate hypertension who regularly take nigella seed extract may see a reduction in blood pressure. Both systolic and diastolic blood pressure values were decreased by seed extracts. Even the seeds' oil can be helpful in this regard. The seeds' ability to reduce blood pressure may be attributed to thymoquinone and thymol. The substances function by lowering cardiac oxidative stress and ACE activity, both of which aid in lowering blood pressure levels.

The diuretic effects of nigella seeds are also responsible for their anti-hypertensive actions. Rats given the seeds had demonstrated a 4% reduction in arterial blood pressure. Studies conducted on crossbred hens showed that supplementation with nigella seeds might boost immunity against the Newcastle disease virus. In yet another UK study, nigella seed oil supplementation was found to improve asthma control and enhance pulmonary function
