Trichosanthes anguina is the long-fruited cultivated form of T. cucumerina.

The plant today

Trichosanthes cucumerina, also called as Pudalangai (புடலங்காய்) is a tropical or subtropical vine. Its variety T. cucumerina var. anguina raised for its strikingly long fruit. In Asia, it is eaten immature as a vegetable much like the summer squash and in Africa, the reddish pulp of mature snake gourd is used as an economical substitute for tomato. Common names for the cultivated variety include snake gourd, serpent gourd, chichinda padwal, Podalanga and Snake Tomato.

Uses

The fruit of T. anguina is purgative, emetic and anthelmintic. The natives use an infusion of the filamentous, reticulate portion surrounding the seeds, in doses of 0.50–0.60 gm., according to P. Blanco.

The second species, T. cucumerina, has a wider use. In India it is regarded as a febrifuge and laxative and is commonly given with some aromatic. Ainslie notes that the leaves, as well as the fruit, are bitter and purgative and that the Tamuls use them for their laxative and stomachic effect. Drury states that on the Malabar coast the seeds have a considerable reputation as a remedy for functional disorders of the stomach. Although the green fruit is very bitter the natives of that region use it as a condiment. The tender stems and the dry capsules, both bitter and purgative, are given in infusion and in a sweetened solution, as an aid to digestion. The seeds are febrifuge and anthelmintic. The juice of the leaves is emetic and that of the roots purgative. The decoction of the stem is expectorant.

In Bombay the plant is considered febrifuge, and is given in decoction with ginger, Swertia chirata, and sugar. The Mohammedan authors say that the T. cucumerina is effective in expelling lumbricoids and one of them mentions the following as a cure for stubborn fevers:

[table omitted; see the source text]

Let stand over night, filter, add a little sugar, administer in 2 doses morning and evening.

In Concan they use the juice of the leaves as a liniment in remittent fevers, rubbing the hepatic region and in fact the entire body.

Flowers white, monœcious. Staminate: calyx 5-toothed with dotted borders; corolla, 5 fringed petals; stamens 3; anthers 3, entirely united and forming a cylinder. Pistillate: 3 glandules in the corolla tube; style long; stigmas 3.
