Lemongrass For High Blood Pressure

Lemongrass is botanically known as Cymbopogon citratus. It grows well in warm and tropical regions, and is widely used in Asian cuisine due to its flavor and citrus-like smell. But, lemongrass also has medicinal properties, and when taken with tea, it can reduce cold and cough symptoms, as well as help control high blood pressure. But how effective is lemongrass for high blood pressure? Let’s take a closer look.

How to Use Lemongrass for High Blood Pressure?

Lemongrass contains antioxidants, phenolic compounds, and flavonoids. It also contains anti-cholesterol and anti-atherosclerosis properties, which reduce the absorption of cholesterol in the intestine, keeping bad cholesterol at bay. Lemongrass helps in the oxidation of LDL cholesterol in the blood and prevents atherosclerotic plaque buildup.

Lemongrass has good amounts of vitamins A and C, as well as zinc. It also has magnesium, potassium, phosphorus, calcium, and iron. The potassium content, in particular, helps regulate blood pressure.

Drinking a glass of lemongrass juice in the morning helps lower high blood pressure and boost blood circulation in the body. It also helps to get rid of uric acid, harmful toxins, and fats, as it works as a diuretic to cleanse and detoxify the body. It increases the frequency and quantity of urination, which helps to flush out bad cholesterol and other toxins.

To use lemongrass for high blood pressure, simply steep dried or fresh lemongrass in a cup of hot water for five to 10 minutes, then strain and add a sweetener. You can also use ready-to-use lemongrass tea bags. Or, you can simply add lemongrass to soups to reap its health benefits.
