Have you ever tried a rose apple? It tastes like snow pear, and it has really high water content. What’s interesting is that it doesn’t look like a regular apple but rather a pear or guava. You can eat it after removing the hairs and seeds, but people usually dry it and prepare it as a tea.

The most popular edible variety is the Syzygium Jambos.

But, do you know if it’s rich in some essential nutrients and whether it provides some therapeutic benefit?

Health Benefits of Rose Apples

1. Improve Digestion

Rose apples are abundant in fiber which facilitates the passage of food through the digestive tract. Besides improving digestion, they help relieve constipation, dysentery, and diarrhea.

2. Regulates Cholesterol

Rose apples can improve unhealthy cholesterol levels by boosting the levels of good (HDL) cholesterol thanks to the niacin content, and reduce the bad cholesterol.

This, in turn, reduces the risk of artery plaque buildup (atherosclerosis) and other cardiovascular problems such as coronary heart disease, stroke, and heart attacks. That’s why consuming this fruit could help support your heart health.

3. Boost the Immune System

Thanks to rose apple’s active and volatile compounds, they possess antifungal and antimicrobial properties which help protect the skin against infections. Also, they help boost the immune system in the protection against infectious diseases.

4. Diuretic

According to studies, the edible variety of rose apples called Syzygium Jambos has diuretic properties which means it helps cleanse the liver and kidneys.

5. Brain and Liver Stimulant

Rose apples were used as a liver and brain tonic in the traditional Indian medicine.

6. Anti-Diabetic Properties

Rose apple leaves contain the alkaloid called jambosine which helps prevent starch converting into sugar. This could be extremely beneficial for people with higher risk of developing diabetes and prediabetes.

Also, one study shows that tea prepared form Syzygium Jambos leaves helps lower blood glucose levels, even though the reduction was not significant.

Other Traditional Uses

  • It is believed that a sweetened preparation of rose apple flowers can help reduce fever.
  • People at Nicaragua are said to use an infusion of roasted, powdered rose apple seeds to improve their diabetes management.
