What is hypertension?
Commonly known as high blood pressure, a common disorder in which, the blood exerts excessive pressure on the arterial walls, which in time can can lead to health problems, such as heart disease.
Blood pressure is determined both by the amount of blood the heart pumps and by the amount of resistance to blood flow in the arteries. The more blood the heart pumps, and the narrower the arteries, the higher the blood pressure.
You can have high blood pressure for years without having symptoms. Even without symptoms, the damage to the blood vessels and to your heart is still occurring and can be detected. Uncontrolled high blood pressure increases your risk of serious health problems, including heart attacks and strokes.
High blood pressure usually appears over a period of many years, and eventually affects almost everyone. Fortunately, it is easily detected and once known, you can work with your doctor to control and reduce it.

Whatmushrooms have useful properties in hypertension?
Shown to reduce hypertension.
There are numerous studies on the effect of Reishi extracts as a reducer of hypertension. The mushroom has shown to regulate angiotensin converting enzyme (ACE) responsible for controlling blood pressure.
Certain compounds present in Polyporus may increase the extraction of water in the body thus having a diuretic effect.
