It is a tropical tree growing to 12 m tall, with evergreen leaves 10–25 cm long and 5–10 cm broad. The flowers are white, 2.5 cm diameter, with four petals and numerous stamens. The fruit is a bell-shaped edible berry, with colors ranging from white, pale green, green, red, purple, crimson, to deep purple or even black, 4–6 cm long in wild plants. The flowers and resulting fruit are not limited to the axils of the leaves and can appear on nearly any point on the surface of the trunk and branches. When mature, the tree is considered a heavy bearer and can yield a crop of up to 700 fruits.

The ripened fruit varies in hue and can be light pink to a dark, almost purple, red. One of the most highly prized and sought after wax apples in Taiwan are “black pearls,” which are purplish-red. If it is ripe enough, the fruit will puff outwards, with the middle of the underside of the “bell shape” dented in a touch. Healthy wax apples have a light sheen to them.

Seeds and cuttings.
Due to recalcitrant nature of the seeds, they have a short viable life, can not be dried well and can not withstand low temperatures.

Edible Uses:
It is a very delicious fruit to eat ,sweet soft and watery.Despite its name, a ripe wax apple only resembles an apple on the outside in color. It doesn’t taste like an apple, and it has neither the fragrance nor the density of an apple. Its flavor is similar to a snow pear, and the liquid to flesh ratio of the wax apple is comparable to a watermelon. Unlike either apple or watermelon, the wax apple’s flesh has a very loose weave. The very middle holds a seed that’s situated in a sort of cotton-candy-like mesh. This mesh is edible but flavorless. The color of its juice depends on the cultivar of the fruit; it may be purple to entirely colorless. As well as in its native range, it is also cultivated in tropical regions such as Vietnam, Taiwan, Thailand, Bangladesh,

Constituents :

• Leaf oil largely composed of monoterpenes (30% sesquiterpenes, 9 % caryophyllene).
• Considered diuretic, emmenagogue, abortifacient, febrifuge.

Medicinal Uses:

Not known in the Philippines for its medicinal properties.
In other countries, the astringent bark is a mouthwash for thrush (dapulak).
A root-bark decoction used for dysentery and amenorrhea.
Powdered leaves used for cracked tongues.
Root-bark used as abortifacient.

Other Uses:

Wood is used for construction, bowls and boards.


• Antiinflammatory: Flavan-3-ols isolated from some medicinal plants inhibiting COX-1 and COX-2 catalysed prostaglandin biosynthesis: S malaccense was one of four plants tested that were traditionally used for inflammatory conditions.
• Antioxidant: Study of 58 underutilized Malaysian fruits of 32 different species, showed fruits from some genera, including Syzygium, had higher antioxidant capacity compared to other general.
• Leaf Oil Analysis: Study of hydrodistilled essential oil from the fresh leaves of SM grown in Nigeria showed the oil to be largely composed of monoterpenes (61.1%) characterized mainly by a-pinene, b-pinene, p-cymene and a-terpineol. The sesquiterpenes constituted 30.8% of the oil with b-caryophyllene as the major component.
• Essential Oils / Non-Ichthyotoxic: Study yielded three compounds – ursolic acid, B-sitosterol, and sitos-4-en-3-one. None of the compounds gave any significant ichthyotoxicity.
• Aldose Reductase Inhibition / Cataract Prevention: Cataractogenesis is a common complication in diabetes, and aldose reductase in a lens enzyme involved in its development. In a study, S malaccense was one of the best four plant extract inhibitors with a preventive effect on cataract formation.
