Discover the 15 health benefits of guava leaves.

Guava is a famous tropical fruit with an interesting taste and high nutrient content.

The fruit comes from a small evergreen tree in the Myrtaceae family that grows well in tropical countries.

Today, the tree that originally came from Central America is widely cultivated in many parts of the world in many of its varieties.


While many people around the world consume fruit as food, not many people understand that the fruit is not the only part of the plant that is high in nutrients and that it can also gain great benefits from guava leaves.

It is not only the fruits that are the edible parts of the tree, but also the leaves.

For a long time, people have been using leaves as a traditional remedy against many common illnesses.

Some people simply crush the leaves and mix them with water before drinking, some chew the leaves and swallow them, but probably the most popular method is to boil the leaves in tea form and apply the crushed leaves topically.


In countries like Mexico and some parts of South America, making guava leaves to make tea is quite common.

Health benefits of guava leaves

Below are the 15 shocking health benefits of guava leaves;

1.- Improves intestinal health

Guava leaves are the most popular for their potential to treat diarrhea.

This is due to the natural phytochemicals in guava leaves, especially anthocyanins and carotenoids which are antioxidants and flavonoids.


These compounds have natural antibacterial, antiviral, and antiparasitic properties.

Like antibiotic medications, these compounds help the body by killing harmful pathogens that cause diarrhea.

The effectiveness of guava leaves for treating diarrhea has been known for centuries by people who use guava leaf tea as a common folk remedy.

However, in 2008, a research report was published, in the study, scientists wanted to examine how effective guava leaves were in treating the bacteria that cause diarrhea.


The scientists concluded that human subjects who received treatment in the form of guava leaf extract experienced faster recovery from diarrhea compared to others who did not.

2.- Improves cardiovascular health

A healthy cardiovascular system is a driver of a healthy life.

Cardiovascular disease, such as heart attack, is the leading cause of death in demographics around the world.

Fortunately, it is possible to reduce your risk of developing cardiovascular disease by making a lifestyle change.


Taking guava tea leaves regularly can also help your quest to maintain a healthy heart.

According to some clinical studies and laboratory studies, drinking guava leaf tea is good for the cardiovascular and circulatory systems.

In the 2005 publication “Methods and Results in Experimental and Clinical Pharmacology,” a study was written on the effect of guava leaf tea on cardiovascular health.

The study used laboratory animals as test subjects.


The animals had high blood pressure at the beginning of the study.

After feeding the animal’s guava leaf extract, the researchers measured the animals’ heart rate and blood pressure and compared them to a control group.

The researchers witnessed a reduction in both markers, showing that the leaf extract is effective in reducing symptoms of cardiovascular ailments such as hypertension.

3.- Lowers cholesterol

In addition to lowering blood pressure levels, guava leaf tea can also help with unregulated cholesterol levels.


High-level cholesterols contribute as the risk factor for many serious diseases, such as heart attack, stroke, and arteriosclerosis.

This is because guava leaf tea can improve blood lipid levels.

A study published in the 2010 “Nutrition and Metabolism” paper investigated this.

According to the study, human subjects who received the guava leaf extract treatment lowered their blood cholesterol levels.


There was also a reduction in the number of triglycerides, although the scientists claimed that more studies and experiments were needed on the subject.

4.- Prevents and treats diabetes

Are you prone to diabetes due to multiple risk factors that you cannot avoid? You should avoid foods that are high in sugar or carbohydrates to suppress the risks.

However, in times when it is simply not possible, you can drink guava leaf tea as the flavonoids and some other compounds present in the tea will stabilize your blood sugar level even after consuming carbohydrate-rich foods.

The study published in the journal Nutrition and Metabolisms reviewed several studies that discovered and investigated how guava leaf tea helps people with diabetes stabilize their blood sugar level.


Some substances in tea inhibit the enzymes that convert carbohydrates into glucose.

Since carbohydrates in the digestive tract are not converted to glucose, the level of sugar in the blood does not rise.

The review also reported on some trials that were conducted in Japan to assess the possible antidiabetic properties of guava leaf tea.

The result showed that regular tea consumption helped lower blood glucose levels after eating high carbohydrate foods.


5.- Control obesity

Losing weight is the goal of many people, especially those who are obese.

It is not only a question of aesthetics but also health problems.

Unfortunately, some people are obese due to a metabolism problem, as their body does not correctly metabolize calories.

Drinking guava leaf tea may be the solution.


The leaves are high in fiber but low in the glycemic index, making them effective as a weight loss supplement.

It is done by preventing starches from turning into sugars.

Sugar is worse than complex starches because typically it is metabolized by the liver into fat rather than used for energy.

When complex starches are not converted to sugar, your weight loss program will work more effectively.


The leaf does not have to be chewed directly to reap the benefits, the extract and tea can simply provide the same result

According to a study published in the 2011 issue of “Food Chemistry,” consuming guava leaf extract will cause apoptosis or a situation where gastric cancer cells simply attack each other.

Cancer cells will gradually die and patients can easily recover from it.

Guava leaf tea is effective in treating many types of cancer, including breast, oral, and prostate cancer.

9.- Decreases the risk of prostate tumor

In addition to gastric cancer, the antitumor and anticancer properties of guava leaves may also work to fight other types of cancer, including prostate cancer.

This benefit is due to the combination of different antioxidants and compounds with anticancer properties such as quercetin, vitamin C, lycopene, and various polyphenols. These compounds neutralize the free radicals that are the cause of cancer.

One study found that guava leaf extract can reduce the risk of prostate cancer in men. Regular intake of guava leaf tea is recommended for this.
