Lowering Blood Pressure

High blood pressure, also known as hypertension, is an extremely common condition, especially among adults, and is referred to as the silent killer due to frequently showing no symptoms, yet leads to numerous serious complications, such as heart disease, stroke, kidney failure, and damaged blood vessels. Alongside medical prescriptions, an increasing number of individuals are seeking natural solutions for the hypertension condition. One of the most popular natural solutions for hypertension is roselle tea.

Roselle (Hibiscus sabdariffa) is known as an herbal plant with plenty of antioxidants and is recognised for its natural blood pressure-lowering properties. Roselle tea is refreshing and contains several beneficial nutrients that nourish the heart and blood vessels. In this article, we are going to discuss the benefits of roselle, how it works to lower blood pressure, the safe dosage, and how to properly prepare roselle tea for the full range of benefits.

What is Roselle?

Roselle is a plant from the Malvaceae family whose flowers are often made into herbal tea. The utilised part is the bright red calyx, which, when soaked or brewed, produces a dark red hue and has a mildly sour and refreshing taste.

Roselle contains a range of important compounds, such as:

- Anthocyanin

- Flavonoid

- Vitamin C

- Polyphenols

- Organic acids (hibiscus acid, citric acid)

- High antioxidants

These compounds give roselle the ability to help reduce blood pressure as well as maintain overall body health.

How does Roselle Tea reduce Blood Pressure ?

The benefits of roselle tea on blood pressure reduction have been proven in a number of studies. The main mechanisms include the following:

1.Natural Diuretic Effect

One of the ways roselle helps in reducing blood pressure is through its natural diuretic effect, which helps the body eliminate excess sodium and fluids. This reduces the pressure on the walls of blood vessels, thereby decreasing blood pressure.

2. Improving and Expanding Blood Vessels

Roselle also possesses blood vessel-expanding and relaxing properties. The anthocyanin content helps to relax the muscles of blood vessels. Relaxed blood vessels allow blood to flow freely, resulting in decreased blood pressure.

3.Inhibition of ACE

Studies have shown that roselle possesses effects similar to a class of drugs used for lowering blood pressure called ACE inhibitors. Roselle inhibits the enzyme ACE, which causes narrowing of the blood vessels. Inhibition of ACE keeps blood vessels open and maintains stable blood pressure.

4.Reducing Oxidative Stress

Hypertension is caused not only by salt factors or emotional stress but also by free radicals. The antioxidants in roselle combat free radicals and reduce inflammation that can lead to the stiffening of blood vessels. When blood vessels remain elastic, it is easier to control blood pressure.

Other Benefits of Roselle Tea

Apart from lowering blood pressure, roselle tea also has various other benefits to the body, such as:

1. Reducing Cholesterol

Its flavonoid content helps reduce bad (LDL) cholesterol and triglycerides while increasing good (HDL) cholesterol, which is important to prevent heart disease.

2. Supporting Weight Loss

Roselle is able to help increase metabolism while inhibiting the absorption of fats. Unsweetened roselle tea is a suitable low-calorie drink for those on a diet.

3. Promoting Liver Health

The antioxidants and active compounds in roselle help protect the liver from damage, improve detoxification, and keep the liver functioning optimally.

4. Controlling Blood Sugar

Several studies show that roselle helps to improve sensitivity to insulin, which is beneficial for diabetic or prediabetic patients.

5. Boosting Immunity

Roselle is high in vitamin C and polyphenols, thus helping to increase the body's endurance and combat infections.
