Bilibi bearing

            The main use of bilimbi fruits is as an ingredient of pickles, sambals, chutneys and curries (it is especially popular for fish curries), to which they add a tangy taste. Slices of the fruit may be served with salads or chilli as a side dish. Ripe fruits are suitable for making jam and the juice can be used as a refreshing drink (provided that generous amounts of sugar are added).

            Though bilimbi is low in calories, but it is a good course of vitamin C containing 30 mg of it per 100 g of pulp.

            The fruit is said to have medicinal value in the treatment of fevers and skin ailments. The juice is traditionally used to remove rust and stains from knife blades, weapons, clothing and hands (the stain-removing properties are ascribed to the high levels of potassium oxalate).

Cultivation:

Bilimbi is rarely cultivated on a commercial scale.  Its trees are mosly planted in home gardens.

            This fruit requires a tropical climate.  The plant requires adequate soil moisture and is quite sensitive to drought. There is only one cultivated form, which can be propagated from seeds or cuttings. The seeds have a low viability and therefore should be sown fresh from the fruit. 

            Fruits are produced sporadically throughout the year.  These are sold fresh on local markets.
