Spread the love

Technological advancement in medical science has led to an increase in research for natural procedures and products for the treatment of various illnesses. It is very appealing to look for cures using natural remedies involving fruits and vegetables.

Going herbal is something that is seen as making life easier without having to face any health risks or side effects. For instance, using watermelon for curing ED (erectile dysfunction) or male impotence instead of Viagra; a medicine widely used by men across the world.

Today, watermelon is often referred to as the natural Viagra for men; a natural remedy available to men for enhancing their sexual performance.

The fruit contains an ingredient, known as L-citrulline, capable of making a compound that aids in the relaxation of blood vessels. The effect resembles that of what Viagra does for men suffering from erectile dysfunction.

L-citrulline is present within the flesh and rind of watermelons. It is believed that a 4-ounce serving of watermelon has around 150 mg of L-citrulline.

When taken in large amounts, it reacts with enzymes of the body and converts into arginine, an amino acid that aids the heart as well as the circulatory and immune systems.

Even though watermelon may be an interesting natural viagra, it’s still not accepted as a perfect substitute for any medical treatment. As a natural fruit, it can help you feel better but it is not an instant remedy for ED!

Erectile dysfunction has a variety of causes, such as the narrowing of the blood vessels due to high cholesterol, diabetes, and high blood pressure.

Is Watermelon Efficient Versus Erectile Dysfunction (ED)?

There is nothing wrong with consuming large quantities of watermelon. As long as you’re not allergic to the fruit or do not have diabetes.

Watermelon is enriched with phytonutrients, such as lycopene, that relax the blood vessels connected with erections. Research from Texas A&M University has given supporting evidence for the link between watermelon and enhanced sexual performance.

However, men who suffer from diabetes ought to consult their doctors as to how much watermelon they can safely eat. Fruits like watermelons are known to increase blood sugar levels; this may pose a problem for some diabetic patients if consumed in large amounts.

If you are dealing with obesity, then over-eating any kind of food can increase your weight; even watermelons that are considered to be low in calories. Large amounts of food should not be consumed if this results in stomach ache or misery due to over-eating.

Research has not discovered any serious contradictions to the benefits of watermelon juice for men who are physically fit. Therefore, there is no objection to using watermelon together with or as an alternative to Viagra.

L-citrulline as Viagra-Like Effect

Research is still in its initial stages regarding just how effective watermelon can be in replacing Viagra. ED medications may not work for or suit every man, resulting in various side effects, and are not recommended for patients suffering from certain conditions. Therefore, watermelon is a welcome alternative if you are unable to take Viagra; there are no side effects to be encountered.

Watermelon can improve erection as it’s a natural L-citrulline source; an amino acid needed for maintaining a proper erection. Viagra increases blood flow to the penis enabling a man to attain better erections on being aroused; L-citrulline does the same thing.

Research shows that the body changes L-citrulline into arginine which then converts to nitric acid. Nitric acid increases blood flow to the penis through a widening of the blood vessels; boosting erections.

Watermelon is mostly made up of water, concentrated watermelon juice has the most quantity of L-citrulline. So, men who are interested in using this fruit as a natural Viagra could get what they want by drinking watermelon juice as a remedy for ED.

Moderate Consumption

Watermelon should be used in a way that ensures you get to consume the highest amount of citrulline. For this, a drink can be made using watermelon rind as research has shown that the rind has more concentrations of citrulline than the edible part.

So, how much watermelon does one eat for treating ED? A daily watermelon intake of three and a half servings may equal the L-citrulline levels of supplements. Orange and yellow watermelon varieties are believed to contain slightly higher citrulline levels than the red watermelon.

Bottom Line

Watermelon is one of many alternative solutions, as a natural way of reducing ED, for men who wish to avoid or cannot use Viagra. Foods with aphrodisiacs substances are proven to help battle this condition.

However, it will not solve the issue over a long period due to ED often resulting from another underlying disorder, like high cholesterol. Men should consult a doctor to decide on the best treatment option. Sometimes, using both natural and medical treatments can work better.

Overall, consuming moderate amounts of watermelon is not a bad idea. This improves libido and provides you with antioxidants similar to those of vitamins A and C.
