Malay Apple.
The ripe fruit is eaten raw though many people consider it insipid. It is best stewed with cloves or other flavoring and served with cream as dessert. Asiatic people in
Guyana stew the peeled fruit, cooking the skin separately to make a syrup which they add to the cooked fruit. Malayan people may add the petals of the red-flowered hibiscus
(Hibiscus rosa-sinensis L.) to make the product more colorful. Malay apples are often cooked with acid fruits to the benefit of both. They are sometimes made into sauce or preserves. The slightly unripe fruits are used for making jelly and pickles..
In Puerto Rico, both red and white table wines are made from the Malay apple. The fruits are picked as soon as they are fully colored (not allowed to fall) and immediately dipped in boiling water for one minute to destroy surface bacteria and fungi. The seeds are removed and, for red wine, the fruits are passed through a meat grinder and the resulting juice and pulp weighed. To this material, they add twice the amount of water and 1 1/2 lbs (680 g) of white sugar per gallon, and pour into sterilized barrels with the mouth covered soon with cheesecloth. Yeast is added and a coil inserted to maintain circulation of the water. The barrels are kept in the coolest place possible for 6 months to 1 year, then the wine is filtered. It will be of a pale-rose color so artificial color is added to give it a rich-red hue. In making white wine, the fruits are peeled, the only liquid is the fruit juice, and less sugar is used, only 1 1/4 lbs (565 g) per gallon, so as to limit alcohol formation over a fermenting period of 3 to 6 months.

bark has been much used in local remedies. It is pounded together with salt, the crushed material is strained through coconut husk fiber, and the juice poured into a deep cut. "The patient must exercise absolute self-control as the liquid bums its way into the flesh and nerves."
In the Molucca, or Spice, Islands, a decoction of the bark is used to treat thrush. Malayans apply a powder of the dried leaves on a cracked tongue. A preparation of the root is a remedy for itching. The root acts as a diuretic and is given to alleviate edema. The root bark is useful against dysentery, also serves as an emmenagogue and abortifacient.
