A wax that coats the fruit is used to make candles[2, 27, 238].

The roots have considerable resistance to soil-borne diseases and they are sometimes used as a rootstock for melons and other cucurbits[206].

  • Medicinal Use

    The wax gourd has been used as a food and medicine for thousands of years in the Orient. All parts of the fruit are used medicinally.

    The rind of the fruit is diuretic[218, 238]. It is taken internally in the treatment of urinary dysfunction, summer fevers etc[238]. The ashes of the rind are applied to painful wounds[218].

    The seed is anthelmintic, anti-inflammatory, demulcent, diuretic, expectorant, febrifuge, laxative and tonic[218, 238]. A decoction is used internally in the treatment of vaginal discharges and coughs[238, 254]. In combination with Rheum palmatum it is used to treat intestinal abscesses[254]. In Ayurvedic medicine the seed is used in the treatment of coughs, fevers, excessive thirst and to expel tapeworms[254]. The oil from the seed is also used as an anthelmintic[240].

    The fruit is antiperiodic, aphrodisiac, diuretic, laxative and tonic[240]. It is used in Ayurvedic medicine in the treatment of epilepsy, lung diseases, asthma, coughs etc[238]. The fruit juice is used in the treatment of insanity, epilepsy and other nervous diseases[240]. Recent research has shown that the fruits contain anti-cancer terpenes[238].

    An infusion of the root is used in the treatment of gonorrhoea[218].

    Demulcent, salve. Facilitates pus drainage[147, 176, 178].

  • Edible Use

    Fruit – raw or cooked[74, 114]. Used as a vegetable, and in pickles, curries and preserves[1, 2, 27, 61, 183]. The fruit can be eaten when it is young or old[116], it can be picked as early as one week after fertilization[206]. A juicy texture with a mild flavour, the flavour is somewhat stronger in younger fruits[206]. Because of its waxy coating, it will store for several months, sometimes as long as a year[116, 206]. Mature fruits can vary in weight from 2 – 50 kg[206]. A nutritional analysis is available[218].

    Young leaves and flower buds are steamed and eaten as a vegetable, or are added as a flavouring to soups[183, 200].

    Seed – cooked[74, 114, 177, 183]. Rich in oil and protein.

Cultivation & Habitat

Seed – sow March/April in a greenhouse. Germination should take place within 3 weeks. When they are large enough to handle, prick the seedlings out into individual pots and grow them on fast in a rich compost in the greenhouse. Try to maintain a minimum night temperature of at least 10¡c for the seedlings first few weeks[206]. Plant out in May/June after the last expected frosts[1].
Requires a warm sunny position in a rich well-drained soil and plenty of moisture in the growing season[1, 200, 238]. Established plants are reasonably drought tolerant[206]. Tolerates a pH in the range 5.8 to 6.8. This species is not very frost hardy, it is best grown in a greenhouse in Britain[86] but can succeed outdoors in good summers if started off in a greenhouse and planted out after the last expected frosts. Plants require stable temperatures in excess of 25¡c if they are to do well[200]. Short daylengths and lower temperatures stimulate female flower development, higher temperatures stimulate male flower production[200]. Plants take 5 months from seed to produce a mature crop, though the fruits can be eaten when immature[206]. The wax gourd is frequently cultivated for its edible fruit in the tropics, there are many named varieties[183]. One group, sometimes classified as B. hispids chieh-gua, is known as the hairy melon or jointed gourd. This form is grown for its immature fruit in much the same way as courgettes are used[206]. Mature fruits of this form do not develop a waxy coating[206]. The fruit can be harvested about 3 months after sowing[206].
Tropical Asia.
