Jambolão – properties and benefits

Jambolão ( Syzygium Cumini Lamarck ) is originally from India, having adapted well to Brazil, especially to the northeast region. It has several names in our country, such as: jamelão, jalão, jambú, jambuí, olive-do-nordeste, etc. The tree belongs to the same family as the guava and the pitanga, the  myrtaceae . The oval and dark fruits are similar to the olive when ripe and, due to the effect of the color of these fruits, the tree is used in ornamentation of gardens, including, in Brasília, it is very common in flower beds and blocks. Here, in Brazil, the fruit is usually consumed fresh, but it can also be used in jams, sweets, liqueurs, wine, vinegar, jellies, pies, etc.

What are the health benefits of jambolão fruit?

The medicinal properties of this plant are not only found in the fruit, but in the leaves and stems as well. Like for example:

  • antibacterial properties,
  • antifungal,
  • antiviral and antiallergic in the leaves and anti-inflammatory and anticarcinogenic in the stem.

Anthocyanins, substances present in the fruit because of its purple color, fight free radicals, preventing premature aging of cells, maintaining the health of the entire body. In addition, they serve as food coloring, and studies have shown that anthocyanins also have a very important function: killing leukemic cells! Published in 2006, the master’s thesis by Daniella Dias P. Campos, from Unicamp, was based on the investigation of the effects of jambolão extract, rich in anthocyanins and which led to the death of approximately 90% of the leukemic cells, in parallel, were applications in healthy cells were tested and their death did not exceed 20%.

Other phytochemicals present in fruit are excellent for protecting health, such as polyphenol, preventing and treating chronic and non-communicable diseases, such as cardiovascular disease.

Studies show that fruit consumption is directly linked to the prevention of chronic and non-communicable diseases, possibly due to the increased consumption of antioxidant compounds, which protect our bodies from carcinogens that come into daily contact with our bodies, which can cause our cells to mutate and form a cancer in the future. These compounds found in some fruits and vegetables, help our cells to defend against this mutation, and jambolão has a great antioxidant activity, even greater than blueberry and black moray , which are widely studied, with the seed being the part with the highest antioxidant concentration than peel or pulp, and can be used in antioxidant extracts.

And for the treatment of diabetes, does jambolão work?

Despite reports and records that the use of jambolão to control blood glucose is old, more than a hundred years, even before the discovery of insulin and that many people use it for this purpose, whether the fruit or the peel and leaves, in tea, this subject is still controversial. Several Brazilian researchers have published their studies on the effects of jambolão on glucose metabolism and show the plant’s efficacy in diabetic rats, but when it comes to the effects on humans, the extract and the tea do not seem to be promising.

In other words, studies around this property of jambolão have not yet been completed and elucidated, although there are old reports and the popular use of the stem and fruit to treat diabetes. Despite this, this plant should not be used alone in the treatment of diabetes, as animal studies do not guarantee efficacy in humans and, in these studies, side effects in humans are not evaluated, so it would be a risk!
