Hypertension: Science discovers the answer in watermelon rind, a powerful healing compound

Watermelon is a sweet, refreshing, low-calorie fruit that belongs to the Cucurbitaceae family. It provides hydration and also essential nutrients like vitamins, minerals, and antioxidants, which are of great benefit to people suffering from high blood pressure , according to Kathy Warwick, a nutritionist and diabetes educator.

Watermelon, as it is also known, is not only highly valued for its flavor, but many people don't know that the peel , which is usually discarded, has a 'healing power' due to its compounds.

One of its main benefits is that it helps strengthen veins and improve blood circulation, regulating blood pressure, which is why experts recommend its consumption.

The non-essential amino acid found in watermelon is L-citrulline, which is involved in the urea cycle, where it helps eliminate ammonia from the body and detoxify the body, according to the 'Healthline' website.

“L-citrulline is very good for blood vessels. And what you're really looking for is for blood vessels to be flexible and able to widen and allow blood to flow , rather than becoming rigid or clogged,” explained dietitian Samantha Cassetty.

This amino acid is transformed into L-arginine, which promotes the generation of nitric oxide , a compound that helps improve blood circulation and cardiovascular function.

According to Medical News Today, in a 2012 study, researchers found that watermelon extract reduced blood pressure in the ankles of middle-aged people with obesity and early hypertension.

Scientists suggested that L-citrulline and L-arginine could improve arterial function. These two antioxidants are also key to preventing cardiovascular disease.

“L-citrulline, an amino acid that contributes to blood pressure control and vascular function. It has a high concentration of lycopene, beta-carotene, and vitamin C, antioxidants that protect against oxidative stress, reduce inflammation, and improve cardiovascular health ,” explained Dr. Jorge Martín.

Among the main benefits of citrulline for regulating blood pressure, the following stand out:

Although watermelon has many benefits, it may have certain contraindications; therefore, it's important to consume it in moderation, especially if you suffer from diabetes, kidney problems, or allergies.
