Basic Description:

Eugenia uniflora is a large shrub or small tree that can grow up to 8 meters in height. It has a conical form with ovate, glossy leaves arranged in opposite pairs. New leaves exhibit a bronze or coppery hue, maturing to deep green, and may turn red during winter. The plant produces white flowers with four petals and a central cluster of stamens. The fruit is ribbed, ranging from green to deep red or black as it ripens, and is edible with a taste varying from sweet to sour.

Distribution and Habitat:

Native to the east coast of tropical South America, including countries like Brazil, Uruguay, and Argentina, Eugenia uniflora has been introduced to various tropical and subtropical regions worldwide. It is often cultivated as a hedge or ornamental plant and has become naturalized in places like Florida and Bermuda, where it is sometimes considered invasive.

Medicinal Properties:

Eugenia uniflora possesses several pharmacological properties:

  • Antihypertensive: Studies have shown that its essential oil exhibits blood pressure-lowering effects.
  • Antidiabetic: Compounds in the plant have demonstrated potential in managing blood sugar levels.
  • Antitumor and Analgesic: The essential oil has shown antitumor activities and pain-relieving properties.
  • Antiviral and Antifungal: It has exhibited activity against certain viruses and fungi.

Additionally, the leaves are used in traditional medicine in Brazil as a stomachic, febrifuge, and astringent. In Surinam, a leaf decoction is consumed as a remedy for colds and, when combined with lemongrass, as a febrifuge.

Known Toxicity:

There are no widely reported toxic effects associated with Eugenia uniflora. However, the plant's leaves and branches emit a resinous fragrance when bruised, which can cause respiratory discomfort in susceptible individuals.

Additional Information:

Eugenia uniflora is valued not only for its edible fruit but also for its ornamental appeal. The fruit is rich in vitamin C and provitamin A, making it a nutritious addition to diets. However, in some regions like Bermuda and parts of Florida, it is considered invasive due to its tendency to spread and displace native flora.
