Pyroxylin is made by treating cotton with equal parts of nitric and sulphuric acids, then washing with water till the latter ceases to give a precipitate with chloride of baryta; then dry in the air.

Collodion is made by dissolving 5 grams of pyroxylin in the following mixture:

Sulphuric ether, rectified 75 grams. Alcohol at 95° 20 grams.

Filter.

Elastic collodion:

Canada Balsam 1.50 grams. Castor oil .50 grams. Collodion 30.00 grams.

Mix.

Botanical Description.--A plant 2-3° high, of herbaceous stem, branches sparsely covered with small, black points; leaves cleft at their base, with 5 lobules and a small gland on the midrib. Petiole long with 2 stipules at the base. Flowers axillary, solitary. Calyx double; the outer portion divided in 3 parts, heart-shaped, and each with 5-9 long, acute teeth. Corolla bell-shaped, of 5 petals, pale yellow or turning rose color, purple at the base. Stamens many, inserted on a column. Stigma in 4-5 parts. Ovary of 3-5 compartments. Seeds enveloped in the fiber.

Habitat.--Batangas, Ilocos.

_Bombax malabaricum_, DC. (_B. Ceiba_, Blanco.)

Nom. Vulg.--_Taglinaw_, _Bobuy gubat_, Tag.; _Talutu_, Vis.

Uses.--In India the roots are used to obtain an astringent and alterative effect and form part of a well-known aphrodisiac mixture called _Musla-Samul_. If the trunk is incised, an astringent gum exudes and this they use in diarrhoea, dysentery and menorrhagia. Dose of the gum 2 1/2-3 grams.

Botanical Description.--A large tree covered with sharp, conical and tough spines. Leaves alternate, compound, digitate, caducous; leaflets 5-7 with long common petiole. Flowers solitary or in axillary cymes, hermaphrodite, regular. Calyx gamosepalous, cup-shaped, with 5 acute lobules. Corolla violet, with 5 deep clefts; æstivation convolute. Stamens numerous, united at the base in 5 bundles, free above, bearing unilocular anthers. Ovary of 5 many-ovulate compartments, with a style ending in 5 short branches. Capsule woody, ovoid, loculicidal, with 5 valves. Seeds numerous, black, covered with cottony fibers.

Habitat.--Angat, Iloilo. Blooms in February.

_Eriodendron anfractuosum_, DC. (_Bombax pentandrum_, L.)

Nom. Vulg.--_Boboy_, Tag.; _Doldol_, Vis.; _Bulak kastila_, Pam.

Uses.--The principal use made of this plant in the Philippines is to stuff the pillows with the cotton that it yields. The leaves, pounded with a little water, yield a mucilaginous juice highly prized by the natives as a wash for the hair, mixing it with _gogo_. The root bark is emetic in dose of 1.25 grm. The cotton yielded by this tree should be used for the same therapeutic purposes as that of gossypium, and being of an exceedingly fine fiber it would give better results. The Filipinos use it to treat burns and sores. I have often used it, being careful always to impregnate it thoroughly with some antiseptic solution. In the treatment of burns it has been my custom to envelope the part in a thick layer of this cotton, after bathing it with a tepid 1-2,000 solution of corrosive sublimate and dusting with a very fine powder of boracic acid.

Botanical Description.--A tree 40-50° high. Trunk somewhat thorny, the branches horizontal, arranged in stars of 3-4. Leaves compound with 7 leaflets, lanceolate, entire, glabrous. Flowers in umbels of 8 or more flowerets. No common peduncle, the individual ones long. Calyx, 5 obtuse sepals, slightly notched. Corolla, 5 fleshy petals, obtusely lanceolate and bent downwards. Stamens 5. Anthers of irregular shape, peltate, with the borders deeply undulate. Stigma in 5 parts. Pod 4-6' long, spindle-shaped. Seeds enveloped in very fine cotton fiber.

Habitat.--Exceedingly common in all parts of the islands. Blooms in December.

STERCULIACEÆ.

Sterculia Family.

_Sterculia foetida_, L. (_S. polyphilla_, R. Br.; _Clompanus major_, Rumph.)

Nom. Vulg.--_Kalumpang_, Tag.; _Bangar_, Iloc.

Uses.--A decoction of the leaves is used as a wash in suppurative cutaneous eruptions. The fruit is astringent and is used in Java as an injection for gonorrhoea. In western India and in the Philippines it is an article of diet. The seeds yield an oil that is used for illumination and as a comestible.

Botanical Description.--A large tree of the first order with digitate leaves of 6-8 leaflets, broad, oval, very acute, tough, glabrous, growing on a long common petiole. No petiole proper. Flowers of a foetid or feculent odor, hermaphrodite, in compound racemes. Calyx fleshy, soft pubescent internally, bell-shaped, in 5 parts. Corolla none. Nectary 5-toothed, on the end of a small column. Stamens 15, inserted on the border of the nectary by threes, forming a triangle. Filament almost entirely wanting. In the midst of the stamens is visible a small, hairy body of 5 lobules which are the rudiments of the ovaries. The style protrudes and twists downwards. Stigma thick, compressed, of 5 lobules. Fruit, five woody pods, semicircular, joined to a common center, each enclosing many oval seeds inserted in the superior suture.

Habitat.--Luzon, Mindanao, Cebú, Iloilo. Blooms in March.

_Sterculia urens_, Roxb. (_S. cordifolia_, Blanco; _Cavallium urens_, Schott. & Endl.)

Nom. Vulg.--_Banilad_, Tag.

Uses.--The root bark is pounded up and applied locally in orchitis and in severe contusions with supposed fracture of the bones; native charlatans pretend to cure the latter condition by this treatment.

The trunk exudes a sort of gum, which with water forms a sort of colorless, odorless gelatin which dissolves at the boiling point. I do not know to what use this gum is applied in therapeutics, but it is often found mixed with the Senegambian gum acacia.

Botanical Description.--A tree with leaves bunched, 7-9-veined, heart-shaped, ovate, broad and entire, glabrous upper surface, short white down on lower surface. Petioles of same length as the leaves. Flowers small, yellow, numerous, polygamous, growing in large, terminal panicles covered with a fine, sticky down. Calyx bell-shaped, 5 acute papyraceous divisions, each bearing a small gland near its base. No corolla. Stamens 10, united in a column, the upper ends free. Five pods joined at one point, half-moon shaped, with woody shell, glabrous within and with a short down on the outer surface. Three or four kidney-shaped seeds, the testa thin and crustaceous.

Habitat.--Cebú, Iloilo.

_Kleinhovia hospitata_, L.

Nom. Vulg.--_Tanag_, Tag., Vis.; _Hamitanago_, Vis.; _Panampat_, Pam.; _Bitnong_, Iloc.

Uses.--The decoction of the leaves is used, according to P. Blanco, to cure the itch. It is also used locally in all forms of dermatitis, and the tender leaves and sprouts are cooked and eaten.

Botanical Description.--Tree 25° high or more, with leaves alternate, heart-shaped, pubescent, almost entire. Petioles long with 2 stipules at the base. Flowers red, axillary, in large panicles. Calyx, 5 sepals, almost linear. Corolla the same size as the calyx, 5 linear petals, the lower shorter and curved. Nectary bell-shaped, of 5 parts, each 3-toothed; set on a column; at its base a wavy fringe with dentate edge. Stamens 15. No filaments. Anthers seated on the 15 teeth of the nectary. Ovary within the nectary, 5-angled, 5 apartments each containing an almost spherical seed.

Habitat.--Luzon, Mindanao, Panay, Cebú, Joló. Flowers in March and September.

_Helicteres Isora_, L. (_H. chrysocalyx_, Miq.; _H. Roxburghii_, G. Don.)

Nom. Vulg.--(?); _Indian Screw Tree_, Eng.

Uses.--I am ignorant of the use that the Filipinos make of this plant, though it is very possible that they do not employ it at all in medicine, which is usually the case with those plants to which they have given no name. In India the peculiar spiral form of the fruit has suggested its application, according to the theories of the doctrine of symbolism. Ainslie says that the Hindoos use it to treat diseases of the external auditory canal. On account of its emollient properties and probably on account of its twisted form, it is used internally as a decoction, in flatulence and the intestinal colic of children. It is indispensable in the marriage ceremonies of the caste of Vaisya, among whom it is customary for the groom to wear on his wrists in the form of bracelets, strings of this fruit combined with that of _Randia dumetorum_.

The root yields a juice which is employed in skin diseases, in abscess, acid in cardialgia. In Jamaica the juice of the leaves is sometimes used for constipation.

Botanical Description.--A small tree with leaves alternate, simple, entire, irregularly nerved or veined at the base, petiolate. Flowers of a handsome red color, hermaphrodite, regular, axillary. Calyx gamosepalous, tubular, of 5 parts. Corolla, 5 free petals slightly dentate at the point. Stamens numerous, united on a free column on the cusp. Compound nectary of 5 unilocular, many-ovuled ovaries. Styles 5, joined at the base. Fruit of 5 carpels, thin, twisted on themselves in spirals, forming a cone, pubescent, of a greenish-brown color, each containing a single row of angular seeds.

Habitat.--Luzon, Panay.

_Abroma fastuosa_, R. Br. (_A. angulata_, Lam.; _A. communis_, Blanco; _A. augusta_, L.)

Nom. Vulg.--_Anibong_, Tag.; _Anabo_, Vis.; _Perennial Indian Hemp_, Eng.

Uses.--The root bark is used in India as an emmenagogue in the congestive and neuralgic forms of amenorrhoea. It seems to act as a uterine tonic. The dose is 2 grams of the juice of the fresh root mixed with pepper which also acts as a carminative and stomachic.

Botanical Description.--A shrub 3-4 meters high with hairy branches. Leaves opposite, oval, oblong, serrate, tomentose. Flowers purple, solitary, terminal. Calyx, 5 sepals. Corolla, 5 petals. Stamens 5, united in the form of a tube. Ovary sessile, with 5 many-ovuled compartments. Styles 5, united in the form of a tube which divides into 5 stigma-bearing branches. Capsule membranous, 5-angled, truncate, dehiscent at apex. Seeds albuminous, covered with filaments of cotton.

Habitat.--San Mateo, La Laguna, Batangas, Iloilo.

_Theobroma Cacao_, L.

Nom. Vulg.--_Cacao._

Uses.--The roasted bean ground with sugar constitutes chocolate, one of the most generally used foods of the Philippines.

It is very nutritious by virtue of the fat and sugar it contains, but all stomachs do not bear it well and its use is the unsuspected cause of much dyspepsia. The custom of drinking it very hot and following with a large quantity of cold water is a very common cause of dilatation of the stomach in the Philippines. The seed of the cacao contains several substances: cacao butter, albumin, theobromine, starch, glucose, gum, tartaric acid, free or combined, tannin, and mineral substances. Of these the butter and theobromine are the most important.

Theobromine (C_7_H_8_N_4_O_2_) is a weak alkaloid, crystalline, slightly bitter, slightly soluble in cold water, more soluble in hot water, less soluble in alcohol and ether; stable in the air up to 100°; sublimes without decomposition at 290° in microscopic crystals of the form of rhomboid prisms ending in an octohedric point (Keller).

This alkaloid is very little used in therapeutics and its physiological

## action is said to be analogous to that of caffeine but weaker. It

is better to use the salt of the alkaloid, and that most frequently employed is the salicylate of soda and theobromine in doses of from 2 to 6 grams daily in solution or pill. Lately, however, Dr. Gram has maintained that theobromine is a powerful diuretic operating when other diuretics fail and further that this effect is produced without injuring the heart. The double salt is non-toxic, though sometimes in exceedingly weak patients it produces vertigo. Dr. Gram administers 6 grams a day in one-gram doses.

Cacao butter is a white substance, slightly yellowish, unctuous to the touch, brittle; with the agreeable odor peculiar to cacao, and a sweet and pleasant taste. Its density is 0.961, it melts at 30°-33°, and solidifies at 25°. It dissolves in 20 parts of boiling alcohol, in 100 parts of cold alcohol and in twice its weight of benzin. Cacao butter is obtained by grinding or mashing the roasted seeds in a hot apparatus and mixing the mass with a fifth or tenth of its weight of boiling water. It is then pressed between two hot iron plates and the butter thus obtained is refined by boiling water. It is then put aside in earthen pans, or still better, in moulds, where it solidifies. It does not easily become rancid and, for this reason, enters into the composition of many ointments and pomades, or is used alone. It serves as the base for suppositories and is, finally, a highly valued cosmetic. A common substitute is made by mixing oil of almonds, wax and animal fat.

Before going further let us describe the composition of Spanish chocolate according to the French chemist Boussingault:

Cane sugar 41.40 grams. Cacao butter 29.24 grams. Starch, glucose 1.48 grams. Theobromine 1.93 grams. Asparagin a trace Albumin 6.25 grams. Gum 1.42 grams. Tartaric acid 1.98 grams. Tannin and coloring matter 0.022 grams. Soluble cellulose 6.21 grams. Ash 2.34 grams. Water 4.36 grams. Undetermined material 3.27 grams. ------ 100.00

Botanical Description.--A small tree about 10° high, with leaves broad, 6-12' long, hanging or drooping, lanceolate, entire, and somewhat pubescent on both surfaces. Petioles very short with 2 deciduous stipules at the base. Flowers in clusters on the roots, trunk and branches. Peduncle very long. Nectary divided in 5 parts, straight, awl-shaped and 2-nerved. Calyx, 5 sepals. Corolla, 5 petals curved upward in the form of a bow as far as the middle, where they form a hollow with two little horns; then curving downwards, then upwards, widening at the end, the edge finely dentate. Stamens 5, inserted on the nectary, and alternating with the lobes of the latter. Anthers 2 on each filament, concealed in the hollows of the petals. Ovary globose. Style awl-shaped. Stigma cleft almost to the middle, 5-parted. Fruit broad, spindle-shaped, 4' or more long, dark reddish, warty, 10-ribbed, with 5 compartments each containing many compressed, ovoid seeds.

Habitat.--Common in orchards and gardens throughout the islands.

GERANIACEÆ.

Geranium Family.

_Oxalis corniculata_, L. (_O. Acetosella_, Blanco.)

Nom. Vulg.--_Taingan dogá, Susokayoli_, Tag.; _Darasig_, Vis.; _Malabalugbug dagis_, _Ayo_, _Kongi_, _Yayo_, Pam.; _Indian Sorrel_, Eng.

Uses.--The part of the plant used in medicine is the leaf which is acid by virtue of the potassium oxalate which it contains. The decoction is used internally as an antipyretic in fevers and in dysentery. Mistaking the properties of the plant it is given for vesical calculus which, if composed of oxalates, would be increased instead of diminished by the treatment. In fact the salt of sorrel in the leaves contains a large quantity of oxalic acid mixed with potassium oxalate. In China, India and the Philippines the entire plant is used as an antiscorbutic.

The cold infusion of the leaves is given internally in doses of from 30 to 60 grams, but it is not a medicine to be given indiscriminately, because in addition to its power of adding to the bulk of calculi of the oxalates, the contained potassium oxalate is poisonous in doses of 25 to 30 grams. If a concentrated solution is taken, it operates as a corrosive poison, producing violent pains in the stomach, vomiting, faintness and great weakness. If the solution is dilute its absorption is rapid and it operates very energetically. When a patient is poisoned by a concentrated solution, the stomach-pump is contraindicated, because the mucous membrane of the organ is corroded and ulcerated; if by a dilute solution, use the pump to remove as much of the poison as possible. The best antidote is a watery solution of a soluble salt of lime, _i. e._, the saccharate, which forms an insoluble salt with oxalic acid.

The juice of the leaves is an antidote for the _Datura_ (Stramonium). In India they make a decoction of the plant, mix it with onion juice and apply it to the head as a fomentation in hemicrania.

Botanical Description.--A plant 1° high, with a creeping, glabrous stem, leaves horizontal, ternate with common long petiole. Leaflets sessile, obcordate, with downy borders. Flowers axillary or terminal, from 1 to 3 in number on a common long peduncle. The pedicel is also long. Calyx common to the family. Corolla, 5 petals ending in small claws. Stamens 10, monadelphous, the 5 shorter ones bearing each a small gland on the outer surface of the base. Ovary large, fluted. Styles 5, short. Stigmas hemispherical. Seed vessel pyramidal, containing many seeds enveloped in an elastic aril by which they are ejected when the fruit opens.

Habitat.--Abundant in Luzon, Panay and Cebú.

_Biophytum sensitivum_, DC. (_B. cumiagianum_, Turez.; _Oxalis sensitivum_, Blanco.)

Nom. Vulg.--_Makahiya_, _Damonghiya_, Tag.; _Mahihiin_, Iloc.

Uses.--A decoction of the leaves is used internally as an expectorant. The bruised leaves are used as an application to wounds and contusions. In Java the decoction is used internally in asthma, phthisis and snake bites.

The peculiar property which this plant possesses of closing its leaves when touched, has caused the natives of India to attribute to it mysterious virtues. Symbolism has determined its therapeutic application and the Hindoos pretend that it endows with delicacy and modesty women who lack these virtues and that it restores virginity.

Botanical Description.--A plant about 7' high. Stem straight, nodose and without branches. Leaves abruptly pinnate, the place of the odd leaflet taken by a stylet. The leaflets nearly linear with a small point at the apex, 11-13 pairs, 2 stipules to each pair. Common petioles long, cleft at the base and disposed in whorls around and on the end of the stem. Flowers sessile, verticillate, on the ends of several very long peduncles which rise from the midst of the petioles. Calyx, 5 sepals. Corolla, 5 petals, clawed, rounded at the end and slightly notched, forming a tube. Stamens 10, free. A small gland on the outer surface of the base of each short stamen. Styles 5. Seed vessels ovate, 5-angled, containing many seeds.

Habitat.--Common in all parts of the islands.

_Averrhoa Bilimbi_, L.

Nom. Vulg.--_Kamias_, _Kalamias_, Tag.; _Kilingiwa_, Vis.; _Pias_, Iloc.

Uses.--The small fruit of the camia springing from the branches and trunks of the trees is widely known in the Philippines, where they eat it green, pickled, and in salad; and when ripe fresh and preserved. Its qualities and therapeutic applications are the same as those of the following species.

Botanical Description.--A tree 4-5 meters high with odd-pinnate leaves. Leaflets 12 pairs, ovate, linear, acute, soft and downy. Flowers small, pinkish or purplish, on trunk and branches. Stamens 10, five alternately longer. Pistils divergent. Fruit oblong, obtuse at the end, with five broad ribs.

Habitat.--Very common throughout the islands.

_Averrhoa Carambola_, L.

Nom. Vulg.--_Bilimbin_, _Balimbin_, Tag.

Uses.--The common name of this tree, whose fruit is so common, causes it to be confused with the name which Linnæus gives to the former species. Balimbin is a fruit of an acid taste, agreeable when ripe, serving the same uses for food as the camia. Its acidity is due to the presence of oxalic acid, which makes the green fruit useful for removing ink and rust stains from clothes. The juice of the fruit is refreshing and is given internally mixed with water and sugar as a refreshing drink in fevers and as an antiscorbutic. For the latter the ripe fruit is eaten uncooked.

In Mauritius the juice is used to treat dysentery and hepatitis. Padre Blanco says that the natives use a decoction of camias and unthreshed rice in diarrhoea and bilious colic. In connection with the subject of camias and balimbins we should mention the fruit treatment of the bilious diarrhoea of the tropics, spoken of by the French physicians of Cochin China. Dr. Van der Burg of the Dutch Indies also strongly recommends the treatment of diarrhoea by fruits; in temperate regions using fruits like peaches, pears, etc., and in the tropics, lychies, mangosteens, etc. In regard to the mangosteens we must not forget that, while the bark is given because of the amount of tannin it contains, the composition of the pulp is very different. The fruit acids seem to exercise great influence in the cure of this obstinate disease and I do not hesitate to recommend for this purpose the camia and the ripe balimbin.

Botanical Description.--A tree much like the former. Leaves odd-pinnate. Leaflets, 3-4 pairs, obliquely ovate, acute, the terminal leaflet nearly lanceolate. Flowers on the trunk, branches and in the axils of the leaves. Fruit oblong, with 5 very prominent acute-angled ribs.

Habitat.--It grows, like the former plant, in all parts of the islands.

RUTACEÆ.

Rue Family.

_Ruta graveolens, L._ (_L. angustifolia_, Pers.)

Nom. Vulg.--_Rudu_, Sp.; _Rue_, Eng.

Uses.--The rue of the European, American and Indian pharmacopoeias is emmenagogue, antispasmodic, anthelmintic, excitant, diaphoretic, antiseptic and abortive. It contains an essential oil, and rutinic acid (C_25_H_28_O_15_, Borntrager), starch, gum, etc. The essential oil is greenish-yellow, thick, acrid and bitter; specific gravity 0.911. It boils at 228°, is slightly soluble in water, and soluble in absolute alcohol. It is promptly oxidized by nitric acid, and is converted into pelargonic acid and other fatty acids.

Rutin (or rutinic acid), according to Weiss, is a glucoside which exists in the form of fine needles, bright yellow in color. It is slightly soluble in cold water and more so in boiling water. It melts at 190°, and solidifies at freezing point, forming a resinous mass. Its physiological properties are as yet unknown. The part of the plant employed is the leaves, which owe their property, apparently, to the essential oil they contain, from which they also derive their strong and disagreeable odor and their bitter, acrid and nauseous taste.

It is used principally as a uterine stimulant or emmenagogue, for which purpose it is given in doses of 0.10-0.15 centigrams of the freshly powdered leaf and 0.05-0.10 centigrams of the fresh leaves infused in a liter of water. The dry powder of the leaf should not be used because the essential oil volatilizes and a large proportion of it is lost, which is the most active principle of the drug. It is an agent which should be prescribed with the greatest prudence for large doses are poisonous even to the point of causing death. The symptoms following such doses are colic, vomiting, bloody diarrhoea and tenesmus.

It is also used as an antihemorrhagic after childbirth, but its action is slow, not being felt for several hours after the administration of the drug; for this reason it cannot take the place of ergot, though it seems to be superior to the latter in passive hemorrhages. The essential oil is given internally in doses of 2-6 drops on a piece of sugar. It is sometimes used as an antispasmodic in hysteria, epilepsy and chorea.

The Chinese make extensive use of this drug and it is one of their principal abortives. In Hindostan the dried leaves are burnt and the smoke inhaled as a cure for catarrh in children. They are careful not to administer it to pregnant women.

Botanical Description.--A plant, 1 meter high, with leaves alternate, compound, the inferior ones 2-3-cleft; leaflets narrow, oblong, slightly fleshy. Flowers greenish-yellow, hermaphrodite, arranged in corymbose terminal cymes. Corolla, 4-5 free, concave petals. Calyx deeply divided, persistent. Stamens 8-10, free, in two whorls, inserted beneath a thick disc. Ovaries 5, unilocular, many-ovuled. Styles 5, first free, then united, forming a column terminating in a small stigma. Follicles 5, united at the base, 1 centimeter long, free superiorly, hard, rounded, rugose, opening on top. Seeds ovoid, angular, blackish, albuminous.

Habitat.--Common everywhere in the Philippines.

_Xanthoxylum oxyphyllum_, Edgew. (_X. violaceum_, Wall.; _Fagara piperita_, Blanco.)

Nom. Vulg.--_Kayutana_, Tag.; _Salay_, _Saladay_, Vis.

Uses.--The trunk bark is stimulant and is used as a sudorific in the treatment of fevers. The fresh bark is quite irritating, for which reason it is best to use bark taken from the more mature parts of the trunk, powdered and desiccated. The dose is 1/2-2 grams 2-3 times a day. Its stimulating properties render it useful in colic and in India it is used as a stomachic and digestive. Is seems also to possess diuretic properties.

Botanical Description.--A tree 30-35° high, with trunk thickly set with large spines. Leaves odd-pinnate. Leaflets ovate, acute, obtusely serrate, small transparent vesicles on the surface, spines on the midrib and common petiole. Calyx very small, monophyllous. Corolla twice as large as the calyx, 4 petals. Stamens 4, inserted on the receptacle, the same length as the petals. Ovary superior, 4-angled. No style. Stigmas 2.

Habitat.--Batangas, Morong, Manila.
