Part 34

Var. L. clavata, Ser. (C. lagenaria villosa, Blanco.)

Nom. Vulg.--Calabaza blanca, Sp.; Opo, Tag.; White Gourd, Eng.

Uses.--The three above-mentioned varieties of L. vulgaris, Ser., are commonly grouped under the name calabaza (gourd). All have the same action and hence the same therapeutic application. The green portion of the rind is bitter and possesses purgative and emetic properties. The decoction of the tender shoots is expectorant; in addition it appears to possess purgative properties and in India is used in jaundice.

The part of the plant most generally used is the seeds, the tænifuge properties of which are well known. Its action, however, is not always certain, which may be as truly said of all other known tænifuges. The seeds have the advantage of lacking the disgusting taste characteristic of other remedies of the same class; the taste is almost neutral and a little sugar conceals it completely. The dose is unlimited; some take 15 grams, others as high as 100, and no unpleasant symptoms of any kind have been reported. The only precaution to be observed is to give the patient a purgative 1-2 hours after his dose.

Heckel has analyzed the seeds and found a resin which he calls pepo-resina; it exists in the greenish pellicle that envelopes the embryo and appears to be the active principle of the seeds. Its dose is 0.80-1.00 gram (Dujardin-Beaumetz), the product of 250 grams of the seeds. The dose of 100 grams of the seeds mentioned above is very small, if the pepo-resin represents the entire active principle, for 100 grams of the seeds would only contain about 40 centigrams.

Botanical Description.--A very familiar vine, clammy, pubescent and musk-scented; large leaves, long-stalked flowers, white petals, greenish veiny fruit usually club-shaped or enlarged at the apex, the hard rind used for vessels, dippers, and so forth. It is noteworthy that none of the tænifuge varieties mentioned bears yellow fruit.

Luffa Ægyptiaca, Mill. (L. pentandra, Roxb.; L. petola, Ser.; Momordica operculata, Blanco.)

Nom. Vulg.--Probably bears the same names as the Trichosanthes.

Uses.--The root is a hydragogue cathartic even in minute doses. The fruit is emollient by virtue of the large quantity of mucilage it contains, but it is more interesting for other properties. When cut in two, deprived of epidermis and seeds, and washed until none of the mucilage remains, there is left a fibrous skeleton, a sort of skein of interwoven nets that constitutes the so-called vegetable sponge. It serves the same purpose as a sponge and has the advantages that its fibers do not rot and that they are easily kept clean. In view of its cheapness and plentifulness in the Philippines the above advantages should suffice to bring it into universal use for the toilet, for surgical purposes and for cleaning in general.

Botanical Description.--A vine with square, glabrous stem. Leaves alternate, cordate, 3-5-lobulate, dentate, rough, 5-7-nerved. Petioles short. Flowers monoecious. Staminate in axillary panicles; calyx bell-shaped; corolla yellow, 5 oval petals, borders entire; stamens 3; filaments short; two thick ones divide high up in 2 parts, thus giving the appearance of 5 stamens in all. Pistillate axillary, calyx adherent, 5 pointed sepals; corolla, 5 nearly triangular petals, finely dentate; style thick, short, the base encircled by 3 glandules; stigma cordate. Ovary, 3 pseudo-locules formed by the central union of the placentas; pluriovulate. Fruit oblong, terminating at the apex in a deciduous lid or cover, marked with 8 or 10 black longitudinal lines; the interior reticulate, 3 compartments with many seeds, oval, black, flat with thin borders. The natives do not distinguish between this specimen and the Trichosanthes, but it is to be noted that the corolla of the former is not ravelled or fringed.

Habitat.--Common in Luzon and Panay. Blooms in January.

Momordica balsamina, L.

Nom. Vulg.--Ampalaya, Ampalea, Tag.; Amargoso, Sp.-Fil.; Paria, Iloc.; Apalia, Pam.; Balsamina, Sp.; Balsam Apple, Eng.

M. charanta, L. (M. muricata, Willd.; M. cylindrica, Blanco.)

Nom. Vulg.--The same as of M. balsamina.

Uses.--The fruit of both varieties is edible, though a bitter principle gives it such an intensely bitter taste that it is intolerable to the unaccustomed palate. It is eaten raw as a salad, or cooked with meat or fish. The juice of the leaves is prescribed internally as a purgative and anthelmintic. In Concan it is given alone or combined with aromatics, in bilious disorders as an emetic and purgative; externally they use it as an ointment for the itch and other skin diseases; in India it is mixed with cinnamon, pepper, rice and oil of Hydnocarpus inebrians, Vahl.

The fruit and leaves are used internally for worms and externally for leprosy. Some Hindoo writers state that the fruit is tonic and stomachic, and that it is useful in rheumatism, gout, diseases of the liver and spleen.

Botanical Description.--The first variety, M. balsamina, more common than the second, is a vine with angular stem and simple tendrils. Leaves, many serrate lobules with white dots on the ends. Flowers yellow, monoecious. Staminate solitary, peduncles very long, involucre cordate; calyx 5-lobed; corolla 5 petals; filaments simple, one separate, 2 approximated; anthers joined at their bases. Pistillate solitary; ovary, 3 locules and numerous ovules; stigma, 3 bifid divisions; fruit globose, narrowing at the ends, covered with tubercles; seeds numerous, lacking albumen, having red aril.

The second variety, M. cylindrica, has a downy stem, 5-angled with simple tendrils. The leaves are 5-lobuled, cordate, serrate, with short hairs on under surface. Melon hollow, glabrous, very long, cylindrical, tapering at the ends, covered with tubercles, some elevated in longitudinal lines, others depressed; seeds in 3 rows, enveloped in pulpy arils, white, long quadrangular, truncate above, encircled by 2 rows of obtuse toothlets.

Habitat.--Both grow in all parts and are well known.

Citrullus Colocynthis, Schard. (Cucumis Colocynthis, L.)

Nom. Vulg.--Coloquíntida, Sp.; Colocynth, Bitter Apple, Eng.

Uses.--The part employed is the fruit pulp, official in all the pharmacopoeias as a very energetic hydragogue cathartic. It is seldom given alone, but in combination with other drugs to modify its energy and its action.

In large doses it causes vomiting, bloody diarrhoea and a series of nervous phenomena that may end in death. Six to ten grams constitute a toxic dose. It operates with most force upon the large intestines and sympathetically upon the uterus.

Dose.--Extract, 0.10-0.30 gram; powder, 0.30-1.00 gram.

The pulp contains a yellow, intensely bitter substance, quite soluble in water and in alcohol, discovered by Hubschmann and named by him coloquintina. The seeds contain 17% of an insipid oil.

Botanical Description.--An herb with long, prostrate stems covered with stiff hairs. Leaves alternate, triangular, deeply cleft in 3 lobules that subdivide. Petioles long. The color of the leaves is pale green above, whitish or gray and covered with white hairs underneath. Flowers yellow, monoecious, solitary, axillary, with long peduncles. Staminate: receptacle cup-formed, 5 sepals and 5 free, yellow petals; 5 stamens in pairs, one free. Pistillate: the receptacle globose, covering the lower part of the ovary; 3 staminodes take the place of the stamens. Ovary unilocular, uniovulate, with a short style bearing 3 lobules at its apex. Fruit globose, 6-8 centimeters in diameter, smooth, greenish, later yellow with white spots; it is full of a whitish pulp that becomes dry and pithy and that contains the obovate seeds, smooth, flattened, brown, lacking albumen.

Habitat.--Manila.
