Herbs for Blood Pressure


Blood pressure is widely known as a silent killer because of the difficulty to detect its outward symptoms. Though it is normal for blood pressure to increase as a part of the normal ageing process, imbalanced diet can contribute more to risks of the disease.

This silent killer invites other health disorders like hypertension that further increases the risk of suffering a stroke. When combined with high cholesterol level, hypertension accelerates the development of Atherosclerosis, i.e., nodular hardening of the arteries. Hypertension can damage kidneys leading to renal failure. It may also lead to blurred vision and later blindness. Environmental factors, like noise may also increase blood pressure level.

Diet is an important factor in the etiology and prevention of various diseases. Research suggests that proper nutrition helps to conquer stress and reduce chances of high blood pressure. Minor changes in our eating habits can lead to major changes in one's health by improving the quality of life.
