Simarubaceæ.

Quassia Family.

Samadera Indica, Gaertn. (Niota tetrapela, DC. & Blanco; Manungala pendula, Blanco.)

Nom. Vulg.—Manungal, Tag., Pam., Bicol.; Manunagl, Linatoganak, Palagarium, Daraput, Vis.

Uses.—The wood and seeds contain an intensely bitter principle. The Filipinos make cups and vases of the wood and allow water to stand in them 6–12 hours, thus preparing a solution of the bitter principle of the plant which they use in various stomach disorders.

Vrij has extracted from the seeds a 33% oil of a bright yellow color, composed, according to Oudermans, of 84 parts olein to 16 of palmitin and stearin.

The bitter principle contained in the root, wood and bark was discovered by Blunse who named it samaderin; it is a white, crystalline, foliaceous substance, more soluble in water than in alcohol, fusible. Nitric and hydrochloric acids color it yellow. Sulphuric acid immediately forms a violet red color which disappears as iridescent, feathery crystals are precipitated. (D. Beaumentz et Egasse.)

The Filipino “herb-doctors” concoct an oil of manungal that in reality contains none of the ingredients of the seeds; it is simply cocoanut oil in which chips of the wood have been soaked. They use it in doses of 30–60 grams as a purgative, externally as an application to the abdomen in colic or indigestion and with friction in rheumatism or contusions. In India the oil extracted from the seeds is used locally with friction in rheumatism.

The decoction of the wood and the powdered wood are given in fevers, in dyspepsia and as a general tonic.

A wineglassful several times a day in cholera, fevers, diarrhœa, etc.

Botanical Description.—A small tree, trunk straight, the wood white and very light in weight. Leaves 4–5′ long, alternate, acute, oval, entire, glabrous, coriaceous, veined. Petioles very short, no stipules. Flowers in terminal umbels, each composed of 4–6 flowerets with moderately long pedicels. Common peduncle, very slender, very long, drooping. Calyx of same color as corolla, inferior, very small, 4-lobuled. Corolla purplish, very long, 4 straight, linear petals. Stamens 8, inserted on the receptacle. Filaments of equal length with the petals, with 1–2 appendices at the base. Anthers spiral. Ovary 5-lobuled, borne on small stalk. One style of equal length with the stamens, situated above the center of the 5 lobules of the ovary which develop into 5 future pods. Stigma simple. Fruit 5 woody pods, short, united centrally above a small base, semi-lunar in form, medianly expanded, venate, containing a small wrinkled, kidney-shaped seed attached by a seed-stalk to the superior suture.

Habitat.—Very common and well known everywhere in the Philippines. Blooms in February.

Burseraceæ.

Myrrh Family.

Garuga pinnata, Roxb. (G. Madagascarensis, DC.)

Nom. Vulg.—Bugo, Tag.

Uses.—The fruit is slightly acid and edible. The trunk exudes an abundant gum, of the odor of turpentine, translucent, greenish-yellow, forming small masses slightly soluble in alcohol, soluble in water, with which a mucilage is formed. The juice of the leaves is used for asthma. The sap is used in Bombay to remove opacities of the cornea. There is another species in the Philippines, G. floribunda, Decsne (Icica Abilo, Blanco), abilo, Tag., the root of which furnishes a decoction used for phthisis. This species also produces a gum-resin similar to that of the bugo.

Botanical Description.—A tree, with leaves alternate, odd-pinnate, without stipules, bunched on the ends of the branches, with opposite, serrate leaflets. Flowers yellowish-white in panicles, compound, polygamous. Calyx bell-shaped, 5-toothed. Corolla, 5 petals. Stamens 10, free, in 2 series. Ovary inferior, 5-lobuled. Fruit, a globose, greenish-yellow drupe with numerous bony seeds.

Habitat.—Everywhere in Luzon, Panay and Balabac.

Canarium commune, L. (C. album and C. Luzonicum, Blanco.)

Nom. Vulg.—Pili, Tag.; Java Almond Tree, East Indian Elemi, Eng.

Uses.—The ripe pili nut is edible and sold in confectioneries. It yields a fixed oil, an excellent sample of which was sent by the Manila pharmacist D. A. del Rosario to the Paris Exposition of 1889. “It is an oil very similar to oil of almond and owing to its physical properties may be used as a substitute for the latter for all the requirements of pharmacy. The only inconvenience connected with its use is the slight one that it solidifies at 3° C. It could furthermore be very advantageously used in the manufacture of fine grades of soap.” (D. A. del Rosario.)

The incised trunk exudes a gum-resin called brea blanca (white pitch) in the Philippines and elemi in Europe. Until recently it was not known in Europe what tree yielded the gum elemi, some authors stating that according to Blanco it was the resin of the Icica abilo, Blanco (Garuga floribunda, Decsne); it is not true, however, that Padre Blanco ever attributed such origin to that product or named his Icica the “pitch-tree.” On the contrary in speaking of the Canarium, Blanco states that it yields a resin called “pili-pitch.” I do not know the reason for this confusion of terms, but presume it to be due to imperfect knowledge of Spanish on the part of those who thus quote Blanco.

Pili-pitch, or elemi, as they call it in Manila, is a substance existing in soft masses, slightly yellowish or gray, resembling old honey in appearance. Its odor is strong and agreeable, somewhat like that of lemon and turpentine. Its taste is acrid and bitter.

The French pharmacist Meaujean demonstrated in 1820 that elemi contains two resins, one soluble in the cold, and the other in hot spirits of wine. Other chemists, among them Baup, Flückiger and Hanbury, have found elemi to be composed of a resinous substance and a colorless essential oil; the proportion of the latter Flückiger gives as 10% and further states that it is dextrogyrous. Sainte-Claire Deville found the essential oil levogyrous, a fact that emphasizes the probability of there being different products in the market bearing the name of elemi.

Baup obtained several principles from it: (1) A resin, brein, fusible at 187°, soluble in cold alcohol, crystallizable in oblique rhombic prisms; (2) another crystalline substance, bryoidin, soluble in 360 parts water at 10°, and melting at 13°; (3) a small amount of breidin, a body soluble in 260 parts water and melting at 100°+; (4) another resin soluble in boiling alcohol, called amyrin.

White pitch is used in the Philippines to make plasters which they apply to the back and breast of patients suffering from bronchial or pulmonary complaints; it is also applied to indolent ulcers. We believe that elemi possesses the same properties as copaiba, and that its indications for internal use are the same.

Botanical Description.—A tree 30–40 meters high, with leaves alternate, odd-pinnate; leaflets opposite, coriaceous. Flowers yellowish-white in axillary, compound panicles, hermaphrodite. Calyx 3-toothed. Corolla, 3 oblong, concave petals. Stamens 6, inserted on the base of the disc. Ovary free, of 3 lobules each containing 2 ovules. Style simple. Stigma, 3 lobules. Drupe oblong, size of large prune, fleshy, containing a hard, 3-sided pit.

Habitat.—Very common in all Philippine woods especially in Camarines.

Meliaceæ.

Melia Family.

Melia Azedarach, L.

Nom. Vulg.—Paraiso (Paradise), Sp.-Fil.; Pride of India, China Tree, Eng.

Uses.—The root was official in the U. S. P., 1880, as an anthelmintic; it is administered in the following form:

Boil till reduced one half.

Dose.—For a child 1 soup-spoonful every 15 minutes till nausea is produced.

In view of the narcotic effects produced by this drug, the foregoing method of administration seems to us imprudent; we prefer to give 30–70 grams of the decoction and follow with a purgative such as castor oil.

This drug is also tonic, febrifuge and astringent, and a decoction of its leaves and flowers is used as a wash for ulcers. Some believe that the leaves and fruit contain toxic principles, which may well be true considering the effects of large doses of their preparations. It has also been observed that the bark collected in March and April may cause dilatation of the pupil, stupor, etc.; this may be explained by the fact that at this season the sap is rising in the tree and the bark contains an increased amount of active ingredients.

The fruit yields a fixed oil, and by fermentation and distillation produces alcohol.

The root bark referred to is bitter and nauseous, if taken from the superficial roots—the part usually employed; the bark of the deeper parts is astringent by virtue of the contained tannin.

Jacobs analyzed the bark and isolated an amorphous resin of yellowish color and very bitter taste. It is soluble in alcohol, ether and chloroform, slightly soluble in sulphuret of carbon, insoluble in turpentine or benzin. He believes that it is the active principle of the root, and produces the anthelmintic action already mentioned: the proper dose is 0.20 centigrams to a child of 4 years, followed by a purge of calomel.

Botanical Description.—A tree, 30–40° high, with leaves alternate, compound, odd-pinnate; leaflets opposite, ovate, pointed, dentate. Flowers in large axillary compound panicles. Calyx, 5 sepals. Corolla, 5 petals, rose-colored within, lilac-colored without. Stamens 10, united into a cylindrical tube, expanded at both ends, the mouth 15-toothed. Anthers inserted near the apex of the tube, short, fleshy, bilocular. Ovary free, of 5 biovuled cells. Style of equal length with the tube. Stigma button-shaped. Fruit a drupe, about the size of a small olive, yellow when ripe, with a dark brown pit of 5 one-seeded cells.

Habitat.—Native of China; is cultivated in most gardens in the Philippines.

Dysoxylum Blancoi, Vidal. (D. salutare, F. Villar; Turroca virens, Blanco.)

Nom. Vulg.—Igiw, Agiw, Taliatan, Tag.; Ananag̃tag̃, Bakugan, Makasili, Vis.; Malabag̃aw, Pam.; Basiloag, Iloc.

Uses.—The bark of the trunk, dry and finely powdered, is used in doses of 1½–2½ grams as an emetic, and, according to Padre Blanco, its effect is very certain.

It is also a febrifuge, and Padre Mercado states that it cures “all forms of asthma, suffocative affections of the chest, and griping pains of the belly.” He also states that it yields marvelous results in malarial fevers, given during the cold stage in doses of 4–8 grams in water or wine in which it has macerated 12 hours. He also recommends its use before breakfast as an anthelmintic in lumbricoids, and finally attributes to it virtues as an emmenagogue.

Padre Blanco calls attention to the species D. schizochitoides, Turcz. (Turroea octandra, Blanco), Himamaw, Tag., as a substitute for D. Blancoi.

The Tagalo “herb-doctors” pretend that the part of the bark near the earth is doubly efficacious, for which reason they administer only that portion which is within one meter of the ground, giving it in the doses already mentioned.

Botanical Description.—Tree 16–20 meters high. Leaves glabrous, odd-pinnate, petioles very long; leaflets entire, opposite, short-petiolate, acute, oblique at the base. Flowers in axillary panicles. Calyx, 5 imbricated sepals. Corolla, 5 linear, lanceolate petals united at the base. Staminal tube, 10-toothed and 10-anthered. Ovary 5-celled, each cell containing two ovules. Style somewhat longer than the stamens. Stigma thick and depressed. Seed vessel globose, depressed, somewhat downy, 5-angled; with 5 compartments each containing 2 seeds.

Habitat.—Batangas and Laguna.

Sandoricum Indicum, Cav.

Nom. Vulg.—Santol, Tag.

Uses.—The santol is doubtless one of the best known fruits in Manila. The most savory portion is the center, which consists of seeds covered with a white pulp of a delicious flavor in the ripe fruit of good quality. The fleshy covering is edible only in the center of the fruit and only a very thin layer of that, the rest having very little flavor. The whole fruit is used in making a confection often prescribed as an astringent. Padre Mercado compares it very appropriately to the quince. The root of the santol is aromatic, stomachic and astringent, by virtue of which latter property it is used in Java in the treatment of leucorrhœa.

Botanical Description.—A tree, 30–40° high, well known in the islands. Leaves ternate; leaflets 4–5′ long, half-ovate, obtuse, entire, stiff and downy, the middle one elliptical. Flowers in panicles. Calyx 5-toothed. Corolla much longer than the calyx, 5 greenish petals, linear and curved downwards. Nectary a cylindrical tube attached to the corolla for half its length, mouth 10-toothed, containing 10 sessile anthers. Style somewhat longer than the stamens. Stigma 5-parted. Fruit about size and form of a small apple, thick, brown, pericarp indehiscent, 5 or more one-seeded compartments.

Habitat.—Grows in all parts of the islands, commonly along the roads.

Carapa Moluccensis, Lam. (Xylocarpus granatum, Blanco.)

Nom. Vulg.—Tabigi, Nigi, Kalumpag̃ sa lati, Tag.; Migi, Pam.

Uses.—The seeds contain a yellow oil, bitter and astringent, with a characteristic odor, having a taste somewhat resembling the odor. In decoction they are used for diarrhœa and dysentery, on account, doubtless, of the tannin they contain. The dose is 1–2 seeds dried, pounded and infused with 200 grams of sweetened water.

The bark, also bitter, is said to be useful in fevers.

In America they extract an oil from the species of the C. Guianensis, Aubl., with which the negroes anoint themselves to keep away stinging insects. Wood soaked in this oil is also proof against insects.

Botanical Description.—This tree, 20° high, grows in swampy districts. Leaves opposite, abruptly pinnate. Two pairs of wedge-shaped leaflets, entire and glabrous. Petiole very short. Calyx inferior, 4–5-toothed. Corolla, 4–5 concave petals, slightly notched at the end. Nectary notched, ovate, 8–9-toothed. No filaments. Anthers equal in number to the teeth of the nectary and inserted between them. Ovary very thick, globose. Stigma shield-shaped. Drupe globose, resembling a very large orange, 5 chambers, each containing 1, 2 or more seeds, convex on one side and concave on the other, angular and much crowded. Testa hard and porous.

Habitat.—Common throughout the Archipelago.

Cedrela Toona, Roxb. (C. odorata, Blanco.)

Nom. Vulg.—Kalantas, Tag., Pam.; Lanigpa, Vis.

Uses.—The infusion of the flowers is antispasmodic. The trunk bark is an excellent astringent, and Dr. Waitz recommends it in extract as a treatment for infantile diarrhœa, for which I also have found it very useful. Blume says that it contains marked antispasmodic virtues, and Dr. G. Kennedy confirms it. Other physicians of India, among them Ros and Newton, have recommended the bark as a substitute for cinchona, given dry in doses of 30 grams.

Infusion.—

Dose.—Several dessert-spoonfuls a day.

The powdered bark is very useful as an application to indolent ulcers which it instantly deodorizes; like powdered quinine it is used in the treatment of superficial gangrene.

Botanical Description.—A large tree. Leaves odd-pinnate. Leaflets oval, lanceolate, acuminate, entire, glabrous, 5–6 pairs. Flowers yellow, in terminal panicles. Calyx 5-toothed. Corolla, 5 oblong petals. Stamens 5, free, inserted on the apex of a disk. Ovaries sessile, 5 many-ovuled cells. Style short. Stigma on a disk. Seed vessel coriaceous, 5 compartments, septicidal, 5-valved. Seeds compressed, pendulous, prolonged in a membranous wing.

Habitat.—Very common in the islands.

Celastraceæ.

Staff-Tree Family.

Celastrus paniculata, Willd. (C. alnifolia, DC.; C. Rothiana, Roem.; Diosma serrata, Blanco.)

Nom. Vulg.—Bilogo, Tag.

Uses.—I am not acquainted with the medicinal uses of this plant in the Philippines. In India, by means of a primitive system of distillation, they extract from the seeds a dark-colored oil of empyreumatic odor, which under the name of Oleum nigrum was once proclaimed by Dr. Herklots as the sovereign remedy for beriberi.

This oil in doses of 10–15 drops a day is a very powerful stimulant, the action of which is manifested by profuse perspiration several hours after its administration. Malcolmson reports that it has given him good results in several cases of beriberi, particularly in recent cases and those in which nervous and paralytic symptoms predominated. In Concan, the juice of the leaves is given in doses of 30 grams as an antidote for opium. The bruised seeds made into a paste with cow urine are used locally in treatment of itch. They are also used in the treatment of leprosy, gout, rheumatism, and other diseases which according to their medical theories, are derived from “cold humors.” For these purposes they give the seeds internally, beginning with one and increasing daily until 50 are taken. At the same time they make external applications of the oil or of another compound prepared in the following way:

Place in an open pot with one opening, seeds of C. paniculata, cloves, benzoin, nutmeg and mace. The pot having been previously heated, is covered with another, inverted over the opening. On the sides of the latter a thick black oil condenses which Herklots very appropriately named Oleum nigrum.

Botanical Description.—A climbing shrub, 6–9° high, without spines. Leaves 6–7′ long by 5′ broad, alternate, petiolate, entire, glabrous, half-ovate. Flowers small and paniculate. Calyx, 5 divisions. Corolla, 5 petals. Stamens 5, inserted in a disc. Anthers oblong. Ovary 3-celled. Stigma 3-lobulate. Style short. Seed vessel the size of a pea, globose, 3-celled, loculicidal, with pulpy seeds.

Habitat.—Tayabas, Laguna, Ilocos North, San Mateo, Albay. Flowers in April.

Rhamnaceæ.

Buckthorn Family.

Zizyphus Jujuba, Lam. (Rhamnus Jujuba, L. & Blanco; Z. Mauritania, Wall.)

Nom. Vulg.—Manzanitas, Sp.-Fil.; Jujube Fruit, Eng.

Uses.—The small fruit known commonly as manzanitas has an agreeable taste, although ordinarily offered for sale before they are quite ripe. They are among the most popular dainties at the fairs and festivals in the provinces of Manila and are the only part of the plant used in medicine. They possess emollient qualities and are official in the codex. They enter in the composition of the so-called pectoral remedies (composed of equal parts of figs, dates, Corinthian raisins and manzanitas).

Botanical Description.—A shrub, with hooked thorns, leaves alternate, petiolate, coriaceous, entire, 3-nerved, 2 thorny stipules, one of them crooked. Flowers small, greenish, axillary. Calyx, 5 oval divisions. Corolla, 5 petals. Stamens 5, free. Ovary bilocular, situated on the disc. Styles 2–3, divergent; small papillary stigmas. Drupe pulpy, globose, resembling a crab-apple in size and taste, enclosing a hard, 2-celled seed.

Habitat.—Common in all parts of the islands.

Rhamnus Wightii, W. & Arn. (Ceanothus Wightiana, Wall.; R. Carolianus, Blanco.)

Nom. Vulg.—Kabatiti, Tag.

Uses.—The dried trunk bark is the part employed in medicine. Hooper analyzed it in 1888 and found a crystalline principle (0.47%), a brown resin (0.85), a red resin (1.15), a bitter principle (1.23), sugar, starch, calcium, oxalate, etc.

As the active principles exist in the resins, an alcoholic tincture of the latter is the best preparation for administration. In India it is used as a tonic and an astringent.

Botanical Description.—A small tree that grows near the sea coast. Trunk 9–12° high, straight, many-branched, devoid of thorns. Leaves alternate, ovate, acutely serrate, glabrous, short-petioled. Flowers greenish-white, axillary, perfect. Calyx 5-toothed, inversely conical. Corolla, 5 petals, smaller than the teeth of the calyx, oval, without claws, notched at the apex. Disc fleshy, smooth, slightly concave. Stamens 5, hidden within the petals. Filaments flattened. Anthers rounded. Ovary fleshy, inserted at the bottom of the calyx tube. Style short. Stigmas 3, divergent. Fruit oval, its base adherent to the calyx, 3 seeds.

Habitat.—Batangas. Blooms in July and October.

Anacardiaceæ.

Cashew Family.

Mangifera Indica, L.

Nom. Vulg.—Manga.

Uses.—The dried and pulverized kernel of the seed is used as an anthelmintic in doses of 1½–2 grams both in India and Brazil. The same preparation is used in the Philippines in the treatment of dysentery and diarrhœa and its effect is doubtless due to the large quantity of tannin it contains. It is administered as follows: The pounded kernels of 20–25 seeds are brought to a boil in 2 bottles (sic) of water. When the liquid has evaporated a third, it is removed from the fire, cooled, decanted, and again placed on the fire after adding three to four hundred grams of sugar. This time it is allowed to boil till reduced to one bottle. The dose is 50–60 grams 2–3 times a day. Incisions in the trunk exude a brownish resin which solidifies in the air, is slightly acrid, bitter, dissolves in alcohol and partially in water. In Malabar it is given internally in the treatment of diarrhœa and dysentery, mixing it with white of egg and opium. But the curative value of the combination is more likely due to the albumen and opium than to the resin. Dissolved in lemon juice it is a useful application in the itch. The trunk bark is astringent and is employed in decoction as a wash for ulcers and eczema and as an injection in leucorrhœa.

The fruit is one of the most highly prized in the Philippines, and resident Europeans are able to eat large quantities of it without ill effects unless the fruit is over-ripe, in which case it often causes transient diarrhœa, which should be treated with a mild purge.

In Mauritius the following compound powder is used in dysentery:

Mix.

Dose.—For an adult one dessert-spoonful every 4 hours; may be given in cauge or arrowroot.

The flowers, testa and bark are, in Hindoo therapeutics, considered “cold,” and “astringent,” and are used especially in diarrhœa. In certain throat affections the Hindoos employ the burning leaves for inhalation. They also use the gum made by evaporating the juice of the ripe fruit, as a confection and an antiscorbutic. Dr. Linguist recommends the bark as a local astringent in uterine, intestinal and pulmonary hemorrhage and employs the following:

Fluid Extract.—

Mix. Dose, 1 teaspoonful every 1 or 2 hours.

Botanical Description.—A noble tree, 30° to 40° high, dome-like or rotund in outline. Leaves dark green, lustrous, alternate, lanceolate, entire; short petioles. Flowers racemose, in verticillate panicles. Calyx, 4, 5 or 6 sepals. Corolla white, fragrant, 4, 5 or 6 petals. Stamens 5, of which perhaps 1, 2 or 3 are fertile. Style on one side of the ovary. Stigma simple. Fruit large, reniform, fleshy, yellow when ripe; contains a large, flattened, reniform pit. Blooms from January even till June. The natives force the fruit by building fires under the trees when but little air is stirring.

Habitat.—Common throughout the islands.

Anacardium occidentale, L. (Cassuvium reniforme, Blanco.)

Nom. Vulg.—Kasuy, Tag.; Caskew Nut, Eng.

Uses.—The pericarp of the nut contains an essential oil which is very irritant and used by the Hindoos as a vesicant; it severely blisters the lips and tongues of imprudent persons who break the nut without taking the precaution of cleansing it of the oil before opening it. In addition to the oil called cardol, the pericarp contains an especial acid anacardic, a little tannin and ammonia. Cardol (C₂₁H₃₁O₂) is an oleaginous, yellow liquid very unstable, neutral, soluble in alcohol and ether, insoluble in water, volatile, and vesicant if applied to the skin. “Anacardic” acid is white, crystalline, odorless, with a burning, aromatic taste. It melts at 26° and decomposes at 200° forming a colorless oil; it is not vesicant, burns with a dark flame, and has the odor of rancid oil. A tincture of the pericarp has been made (1 part to 10 of alcohol) and given internally as a vermifuge in doses of 2–10 drops. Cardol, according to some authors, does not exercise a vesicant action in the gastro-intestinal canal, because it is not dissolved by the gastro-intestinal juices; I am sure, however, that I have seen a choleraic diarrhœa brought on by swallowing, in fun, the pericarp of one nut and a half. Cardol is eliminated by the urine.

The kernel is edible and has a very agreeable taste when roasted. By expression it yields a sweet, yellowish oil, density 0.916.

The trunk exudes a gum resin in masses varying in color from red to yellow.

The fleshy part, called the fruit, is edible but contains a certain quantity of cardol not only evidenced by the odor but by the smarting of the mouth and throat after eating. It is very juicy and the expressed liquid is fermented in Bombay and distilled to make a very weak alcohol which sells for the very low price of 4 annas (5 cents gold) a gallon. This alcohol is again distilled and a stronger obtained which sells for 1½ rupees a gallon. The Portuguese of India make a sort of wine from the fermented juice of the fruit, which, like the weak alcohol we have mentioned, is a well-known diuretic and is used as a liniment.

The gum resin of the trunk contains 90% of anacardic acid and 10% cardol. Wood soaked in it is preserved from the ravages of insects, especially of white ants, for which purpose it is used by bookbinders also. Therapeutically it is used externally in leprosy, old ulcers and to destroy corns, but on account of its rubefacient and vesicant qualities it is necessary to use it cautiously.

Botanical Description.—A tree, 18° high, with leaves cuneiform, glabrous, stiff, short-petioled. Flowers polygamous in terminal panicles. Calyx with 5 erect segments, imbricated, caducous. Corolla, 5 linear, lanceolate petals, curved and imbricated. Stamens 8–10, all fertile. Filaments united to one another and to the disc. Ovary heart-shaped. Style filiform and eccentric. Stigma defective. Ovule solitary. Fruit a reniform nut enclosed in a pulpy pyriform body, formed by the matured disc and extremity of the peduncle. Seed reniform, testa membranous.

Habitat.—Common throughout the Archipelago. Blooms in February.

Odina Wodier, Roxb.

Nom. Vulg.—Amugis, Tag. and Vis.

Uses.—The bark is very astringent and in decoction is used for chronic ulcers. In India Dr. Kirkpatrick has used it as a lotion in impetigo. It has also given good results as a gargle in affections of the pharynx and buccal cavity.

The trunk exudes a gum called in India “kanni ki gond,” an article of commerce. It is almost odorless and has a disagreeable taste. It is only partially soluble in water, forming a viscid mucilage. It is used in the treatment of contusions and sprains and is edible when mixed with cocoanut milk.

Botanical Description.—A tree, with leaves bunched at the extremities of the branches, oblong, oval, acuminate, odd-pinnate, 3–4 pairs of opposite leaflets. Flowers greenish-white, polygamous, in terminal panicles. Calyx gamosepalous, 4 rounded lobules. Corolla, 4 imbricated petals. Stamens 8, free. Ovary 4-parted. Pistillate flowers; ovary sessile, oblong, unilocular. Style 4-parted, thick. Drupe oblong, compressed, unicellular. Testa hard, with 1 non-albuminous kernel.

Habitat.—San Mateo.

Moringeæ.

Moringa pterygosperma, Gaertn. (M. oleifera, Lamk.; M. poligona, DC.; Guilandina Moringa, Blanco.)

Nom. Vulg.—Malug̃ay, Kamalug̃ay, Kalug̃ay, Tag.; Dool, Malug̃it, Vis. and Pam.; Horse Radish Tree, Indo-Eng.

Uses.—The root is vesicant and the Filipinos bruise it and use it for sinapisms. I have often observed, however, that it is quite painful used in this way. Dr. Waitz states that it is a good plan to add a few drops of the root juice to mustard sinapisms, a proceeding which seems to me superfluous, especially in the case of children as he advises it.

The Bengal pharmacopœia contains the following official preparations:

Compound Spirit.—

Mix and distil 4 liters.

Dose.—8–30 cc. as a stimulant and diuretic.

Compound Infusion.—

Dose.—30–60 grams a day, as a strong stimulant.

The expressed seeds yield a fixed oil, which is irritating and in my opinion should not be used internally.

The green pods, the flowers and the tender shoots of the leaves are eaten stewed. The juice of the leaves is given internally in India, as an emetic, in doses of 30 grams.

Botanical Description.—A well-known tree, 5–6 meters high. Leaves 3-pinnate, their terminal divisions odd-pinnate. Leaflets oval, glabrous, entire. Calyx, 5 unequal petaloid segments, imbricated, caducous. Corolla white, 5 unequal petals. Stamens inserted on the border of a disc, unequal, 5 opposite the petals bearing anthers, 5 alternate without anthers. Anthers dorsal, unilocular. Ovary pedunculate, lanceolate, unilocular, with many ovules in 2 series, inserted on the parietal placentæ. Fruit a pod terminating in a beak, 3-valved. Seeds numerous, very large, winged, embedded in a spongy substance.

Habitat.—Common throughout the islands. Blooms in November.

Leguminosæ. (Papilionaceæ.)

Pulse Family.

Agati grandiflora, Desv. (Sesbania grandiflora, Pers.)

Nom. Vulg.—Katuray, Tag.

Uses.—The flowers are edible. They and the leaves are purgative and are given in decoction for this purpose, 30–40 grams to 200 of water. The juice of the flowers is a popular remedy in India, for migraine and coryza. The trunk bark is bitter and tonic.

Botanical Description.—A tree, 4–6 meters high, with drooping limbs; leaves long, very narrow, abruptly pinnate; many caducous leaflets, linear, elliptical. Flowers large, white, fragrant, in axillary racemes. Calyx bell-shaped with two indistinct lips. Corolla papilionaceous, white. Standard oval, a slight notch at the apex. Wings almost as large as the keel which is strongly arched. Stamens 10, diadelphous. Anthers uniform. Style and stamens equally long. Stigma a small head. Pod 1–2° long, linear, 4-sided, containing many oval seeds, separated by filamentous partitions.

Habitat.—Grows in all sections of Luzon and Panay.

Abrus precatorius, L.

Nom. Vulg.—Saga, Sagamamin, Bag̃ati, Tag.; Bag̃ati Gikosgikos, Vis.; Kanaasaga, Pam.; Bugayon, Iloc.; Jequiriti, Prayerbeads, Eng.

Uses.—The part of the plant most important in therapeutics is the seed, the size of a small pea, bright red with a black spot, hard and shining. The Filipino children use them to make rosaries and other decorations. In the distant past the Filipinos used these seeds to weigh gold, a practice followed even to-day by the Hindoos. The famous Susrutas, author of the “Ayur Veda,” recommends them internally for nervous diseases; modern therapeutics, however, limits their use to one disease, though that is frequent and stubborn enough, namely chronic granular conjunctivitis.

Some physicians state that these seeds are poisonous and others the contrary, but the fact that they are used as food among the poor classes of Egypt, demonstrates their harmlessness in the digestive tract at least; when introduced into the circulation they undoubtedly exercise a toxic effect. We have already mentioned that their use is limited nowadays to the therapeutics of the eye; the decoction of the seeds known in Europe under the name of “Jaqueriti”—so named in Brazil—produces a purulent inflammation of the healthy conjunctiva and it is precisely this counter-irritant effect which makes it useful in chronic granular conjunctivitis, the persistence of which has defied the most heroic measures of therapeutics. The French oculist, Dr. de Wecker, was the first to employ jequirity for this purpose, in the form of a 24 hours’ maceration of the seeds, 10 grams to 500 grams of water. It is necessary to use a product recently prepared and with this several applications a day are made. It is now known that the inflammation of the healthy conjunctiva is not caused by germ-life contained in the solution but by an inorganic ferment discovered by Bruylans and Venneman and named jequiritin; they state that it is produced during the germination of the seeds or of the cells in the powdered seeds. Warden and Waddell, of Calcutta, have isolated an essential oil, an acid named “ábric” and an amorphous substance called abrin, obtained by precipitation with alcohol from a watery infusion of the pulverized seeds. Its action is identical with that of “jequiritin.”

The infusion appears to possess considerable value as a stimulating application to indolent ulcers.

The root is a good substitute for licorice, is emollient and has an agreeable taste. The extract is useful in catarrhal diseases of the bronchi and in dysuria. The leaves contain the same properties as the root and an extract prepared from them is used as a substitute for licorice.

Botanical Description.—A vine, with leaves opposite, abruptly pinnate, a stylet taking the place of the terminal leaflet. Leaflets linear, entire, glabrous, tipped with a small point. Common petiole with 2 awl-shaped stipules at the base. Flowers in small racemes. Calyx gamosepalous, caducous, 4–5 short teeth. Corolla papilionaceous, wings horizontal. Stamens 9, monadelphous with bilocular anthers. Style very short. Stigma globose. Pod 4–5 cm. long, truncate at the ends, with 5–6 red seeds, each with a black spot.

Habitat.—Common in all mountainous regions of the islands. Grows near houses and roads.

Mucuna pruriens, DC. (M. prurita, Hook.; M. utilis, Wall.; Dolichos pruriens, L.; Carpopogon pruriens, Roxb.)

Nom. Vulg.—Nipay, Lipay, Vis.

Uses.—The pods are official as an anthelmintic in the Pharmacopœia of India. They are used in the form of an electuary triturated to the proper consistency with honey or syrup. The dose for adults is one soupspoonful, and for children a teaspoonful, given every morning for 3–4 consecutive days. The last day a purge is given to expel the lumbricoids.

Botanical Description.—A vine with ternate leaves. Flowers red, keel larger than the standard and wings. Pods about as thick as the little finger, lacking transverse grooves, curved in the form of the letter f, covered with bright red down, which causes an unendurable itching. They are divided into 3 or 4 oblique cells each containing a brown, shiny seed.

Habitat.—Luzon and Panay.

Erythrina Indica, Lam. (E. corallodendron, L.; E. carnea, Blanco.)

Nom. Vulg.—Dapdap, Kasindik, Tag.; Dapdap, Kabrab, Vis.; Dapdap, Sulbag̃, Pam.; Indian Coral Tree, Eng.

Uses.—This tree is well known on account of the beauty of its crimson flowers. The decoction of the leaves is a useful cleansing and deodorizing application for ulcers. The bruised leaves are used locally in painful affections of the joints and to abort syphilitic buboes and abscesses of all kinds. The juice of the tender leaves is used in Concan to destroy maggots in ulcers, and the powder has a similar use. A decoction is used locally in ophthalmia.

The root and the leaves are used as a febrifuge in the Philippines and in India, according to Wight. In Brazil the bark is given in small repeated doses as a hypnotic and in the Philippines as a diuretic and purgative; a decoction of the leaves is similarly used. The bark contains an alkaloid discovered by Rochefontaine and Rey, called erythrin, which acts upon the central nervous system, diminishing its normal functions even to the point of abolishment, without modifying motor excitability or muscular contractility. W. Young isolated a glucoside, migarrhin, similar to saponin, but possessing the additional property of dilating the pupil.

In bronchitis with dyspnœa the following infusion of bark is very useful:

Boil till reduced one-half, filter and add:

Dose: Wineglassful every two hours.

Botanical Description.—A large tree, 20° high, thorny, with ternate leaves. Leaflets rhomboid, broad, entire, glabrous. Secondary petioles: that of the middle leaflet long, bearing 2 glands, those of the others short, bearing 1 gland each. The leaves fall at the end of the rainy season and the flowers bloom. They are a handsome scarlet color, large, in terminal racemes. Calyx half-cylindrical, oblique, truncate, entire. Corolla papilionaceous; standard elongated, lanceolate. Wings short. Keel very short, 2-lobuled. Stamens diadelphous. Anthers large. Ovary woolly. Stigma thick. Pod curved, rounded, furrowed in parts corresponding to the seeds which are numerous, oval, pointed at the ends.

Habitat.—Common throughout the islands. Blooms in February.

Clitoria ternatea, L.

Nom. Vulg.—Kolokantig̃, Pakingag̃, Tag.; Kolokatig̃, Vis.; Butterfly-pea, Eng.

Uses.—The pounded seeds mixed with oil are used locally for painful joints. They possess purgative and emetic properties and Dr. J. Shartt has employed a mixture of the powdered roasted seeds, 8 grams, with double the quantity of acid tartrate of potassium. Its action is gentle, but sure. The alcoholic extract of the root, a soft, brown, resinous substance with an odor recalling that of jalap, is a very active cathartic, producing sharp effects in doses of 30–60 centigrams; in fact it produces such severe tenesmus that its use in such doses should not be recommended.

The root bark is used internally in an infusion (4–8 grams to 1 liter of water) as an emollient in irritability of the bladder and urethra and has been recommended for such a purpose by Mooden Sheriff. It is a diuretic which frequently acts as a purgative, a fact that is not surprising in view of the above-mentioned properties of the alcoholic extract.

The roasted seeds used as a purgative are so trustworthy that they deserve the further attention of physicians.

Botanical Description.—A vine very well known by its blue flowers. Leaves alternate with 3 pairs of oval leaflets. Stipules persistent. Flowers axillary, solitary, 1–1½′ in long diameter. Calyx in 5 acute divisions, the two upper ones smaller. Corolla papilionaceous. Standard open, notched at the end. Keel shorter than the wings and covered by them. Stamens 10, 9 united and 1 free. Stigma downy, thick. Pod full of short hairs, with more than 6 surrounded with a tow-like substance, reniform, with black spots.

Habitat.—Common along the roads and in gardens. Flowers in July and November.

1. Pterocarpus santalinus, L.5

Nom. Vulg.—Narra, Naga, Tag.; Apalit, Daytanag, Pam.; Red Saunders or Red Sandalwood Tree, Eng.

2. P. Indicus, Willd. (P. pallidus, Blanco.)

Nom. Vulg.—Asana, Tag.; Naga, Vis.

3. P. erinaceus, Poir. (P. echinatus, Pers. & DC.)

Nom. Vulg.—Asana, Narra, Tag.

Uses.—The wood of the first is the so-called “red sandalwood.” It is used for building purposes and, in medicine, as an astringent. In decoction it is used as a gargle for sore throat. The second is also an excellent building material and is used medicinally for its astringent properties. A decoction of sufficient strength to color the water a light blue is used as a mouth wash in toothache and has some reputation as a solvent of vesical calculi. All three species yield a resin known in pharmacy under the name of “kino.” The true gum kino is really produced by the P. marsupium, Roxb., but the Philippine product, especially that of the second and third species, has for a long time been exported to Europe under the name of “red astringent gum” or “kino.” This name is given to the sap of these trees dried without the aid of artificial heat. The bark is the part which produces it and the following extractive process is employed in Madras: a vertical incision is made in the trunk and lateral incisions perpendicular to it and a receptacle is placed at the foot of the tree. This soon fills and when the gum is sufficiently dried by air and sun it is packed in boxes and exported.

In respect to appearance, solubility and chemical composition, Flückiger and Hanbury were unable to discover any difference between the kino of P. marsupium, Roxb., and that of P. erinaceus, Poir. It is therefore interesting to consider a product that is identical with that described in the pharmacopœias as produced by the P. marsupium, Roxb., though the latter does not grow in the Philippines.

Kino is at present used but little in therapeutics and its action is analogous to that of tannin and catechu. It is given internally for its astringent effect in chronic diarrhœa, leucorrhœa, blenorrhœa and hemorrhages. The dose of the powder is 1–4 grams, and of the alcoholic tincture, containing 20 parts kino to 100 of alcohol, 5–10 grams. In prolapse of the rectum and anal fissure the following solution is used by enema:

For vaginal injections a solution of 20 to 250 water.

Botanical Description.—The “pterocarpus,” L., is a tree of the first order with odd-pinnate leaves. Leaflets alternate and coriaceous. Flowers yellow, in racemes, with caducous bracts and bractlets. Calyx turbinate, with short teeth. Petals exserted, markedly unguiculate. Standard and wings curled. Keel obtuse with its petals slightly or not at all coherent. The staminal tube, cleft above and below or above only. Stamens superior, often almost, and at times entirely, free. Anthers versatile. Ovary pedunculate, with 2 ovules. Style curved. Stigma terminal. Pod orbicular, smooth or spiny, usually containing one seed, encircled by a broad, rigid wing, the point curved downward.

Habitat.—In the mountains of Luzon, Panay and Mindoro. Blooms in March.

Pongamia glabra, Vent. (Robinia mitis, L.; Gadelupa maculata, Blanco.)

Nom. Vulg.—Balikbalik, Tag.; Butog̃, Vis.

Uses.—The oil expressed from the seeds is used in India for lighting purposes, and in addition is of notable therapeutic value. It is an excellent local remedy for the itch, for herpes and especially for pityriasis versicolor, used alone or emulsified with lemon juice. In stubborn cases Dymock recommends the addition of oil of hydrocarpus, camphor and powdered sulphur. Dr. Gibson states that he knows of no plant in the vegetable kingdom possessing more notable curative properties in itch, herpes and other cutaneous diseases than the plant under consideration. It is also used as an embrocation in articular rheumatism.

The powdered leaves mixed with common salt and pepper are given internally with a little milk, as a remedy for leprosy.

The juice of the root makes a useful wash for gangrenous ulcers and a good injection for fistula.

Botanical Description.—A tree, 18° high, with leaves opposite, odd-pinnate. Leaflets in 3 pairs, ovate, lanceolate, entire, glabrous and membranaceous. Flowers slightly spotted, racemose. Calyx bell-shaped, with 5 scarcely visible toothlets. Corolla papilionaceous, petals equal, clawed. Standard with 2 callosities athwart the base. Stamens 10, diadelphous. Pod with one seed, which is flat, smooth, veined, bright red.

Habitat.—Luzon and Panay. Blooms in October.
