_Euphorbia pilulifera_, L. (_E. capitata_, Lam.; _E. hirta_, Blanco.)

Nom. Vulg.--_Golondrina_, Sp.-Fil.; _Gatasgatas_, _Batobatonis_, _Sayikan_, Tag.; _Buyayawa_, _Tawawa_, _Bowi_, Vis.; _Malismalis_, _Sisiwhan_, _Bolobotones_, _Magatas_, Pam.

Uses.--This plant has a reputation in the Philippines as a haemostatic of great efficiency, for which purpose the whole plant is crushed and applied as a poultice over the wound. Like all members of this family it abounds in milky juice. We have had no occasion to employ it as a haemostatic, but do not doubt its action in view of the effect that it exercises on the circulation and the heart when given internally. In toxic doses experiment has demonstrated that it kills animals by suspension of the respiratory movements and those of the heart, which at first beats faster but gradually more slowly. It has no effect upon any other organ and is eliminated by the liver.

Matheson recommends it as an antispasmodic and has employed it also in dyspnoea of cardiac origin. I have used it in both these conditions in Manila with highly satisfactory results. I have found the most convenient form of administration to be the tincture in doses of 15-40 drops a day given in an infusion of althaea every 3 or 4 hours; the vehicle should be used liberally as it diminishes the irritant action of the euphorbia on the stomach. A decoction of 15 grams of the plant to 2 liters of water may be given in doses of from 6 to 12 tablespoonfuls daily. A proper dose of the alcoholic extract is 10 centigrams in 24 hours. Dr. Daruty, of Mauritius, gives the following formula:

_Euphorbia pilulifera_ dried in the shade 30 grams.

Water 1 1/2 liters.

Boil till reduced to 1 liter, cool and add:

Rum or cognac 30 grams.

Dose.--1 winegla.s.sful 3 times a day.

This decoction relieves the most obstinate asthma, as well as cough and bronchial irritation. It is necessary to use the entire plant. The decoction is usually given in the morning, fasting, in the middle of the afternoon and at bedtime. In very stubborn cases another dose may be given in the middle of the night. Frequently the relief is immediate and in some cases a liter of the decoction is enough to effect a cure. If the symptoms return, it is easy to abort them; they are less distressing and, according to the statements of patients, the medicine "gives them air."

Dr. Hicks Bunting found, in an a.n.a.lysis of the drug, 60 per cent. of insoluble residue, wax, "caucho," resin, tannin, sugar, alb.u.minoids, oxalate of calcium and other salts.

Dr. Marsset states that the active principle is soluble in water, in dilute alcohol; insoluble in ether, chloroform, bisulphide of carbon, and turpentine, but does not give the reaction.

The toxic dose is 1 gram of dried plant for each kilogram of weight of the animal.

Botanical Description.--A small creeping plant with milky juice. Stem 1-2 high, cylindrical, hairy and reddish in color. Leaves opposite, obliquely ovate, rhomboid, serrate, hairy. Petioles very short. Two pointed stipules at the base. Flowers yellowish in hemispherical umbels of 5 divisions, each subdivided in 2. Involucre universal. Calyx bell-shaped, laciniate, in 5 parts. Corolla, 5 petals, inserted on the divisions of the calyx, fleshy, orbicular, with an orbicular appendix at the base, concave and differing from the corolla in color. Stamens 8, inserted on the base of the calyx; filaments unequal in length, each bearing 2 anthers. Four filaments lacking anthers. Ovary with stalk longer than the flower, curved downward. Styles 3, bifid. Stigmas simple. Seed vessels 3, united, hairy, 3-angled, each bearing 1 red globose seed with a wrinkled surface.

Habitat.--Common in all parts of the islands and well known to the natives. The name by which it is best known in Manila is "golondrina."

_Euphorbia neriifolia_, L. (_E. ligularia_, Roxb.; _E. pentagona_, Blanco.)

Nom. Vulg.--_Sorosoro_, _Sorog-sorog_, _Bait_, Tag., Pam.; _Karambauaya_, Iloc.; _Lengua de perro_, Sp.-Fil.

Uses.--The princ.i.p.al medicinal use of this plant in the Philippines is the introduction of the hot juice of its fleshy leaves into the external auditory ca.n.a.l in cases of otorrhoea or of simple earache, whatever its cause.

The root is regarded in India as an antidote for snake bite and, indeed, the plant is sacred to Munsa, the snake divinity. During the months of July and August in some parts of India the natives make offerings of rice, milk and sugar to this sacred tree every Tuesday and Thursday, praying for protection from the bites of serpents.

The leaves contain an abundance of milky juice, acrid and very active, used in the treatment of several skin diseases. Like the species _E. pilulifera_ it possesses antiasthmatic properties; Dr. S. C. Amcobury reports 6 cases treated with satisfactory results. Owing to the acrid quality of the juice great care should be maintained both in its internal and external use. The Sanscrit authors regard it as purgative and usually administer it with other drugs of the same action to increase its effect. Ainslie states that the native herb-doctors of India give the juice in intestinal obstruction and in the oedema of malarial cachexia. The dose is 1.25 grams in 24 hours given in 300 cc. of sweetened water in divided doses. This dose is, in my opinion, dangerous; 40-60 centigrams a day is more prudent.

Botanical Description.--A small tree, from 5 to 6 high. Trunk erect, jointed, 5-sided, at the angles 2 rows of thorns. Leaves spatulate, fleshy. Flowers yellowish. Calyx bell-shaped, 5-lobed. Corolla, numerous imbricated, spatulate petals with ravelled or fringed ends. Stamens in groups. Styles 3. Stigma coa.r.s.e. Seed vessel, 3 carpels on a stalk.

Habitat.--In all parts of Luzon.

_Euphorbia Tirucalli_, L.

Nom. Vulg.--_Consuelda_, Sp.-Fil.; _Katwit_, _Suelda_, Tag.

Uses.--The milky juice of this species is very caustic. It is used chiefly in India mixed with oil as an embrocation for rheumatism; given internally it is regarded as an antisyphilitic. Dr. J. Shortt states that it is an excellent alterant in syphilis in dose of 30 centigrams, morning and evening. It is further employed in malarial hypertrophy of the spleen, in asthma and as a purgative; in a word the same virtues are attributed to it as to the foregoing species.

Botanical Description.--Small trees, 9-12 high. Trunk erect. Branches cylindrical, stumpy (not tapering), several very small leaves at the ends. Flowers yellowish, in umbels. Calyx, 5 rounded, fleshy sepals. Corolla, 5 groups of woolly hairs on the divisions of the calyx. Stamens 5, inserted on the sepals, with double or irregular anthers. Seed vessel, 3 carpels each with one seed.

Habitat.--Very common, especially in the suburbs of Manila where they serve as hedges.

_Phyllanthus reticulatus_, Mull. (_Cica decandra_, Blanco.)

Nom. Vulg.--_Tinatinaan_, _Tintatintahan_, _Malinta_, Tag.; _Sungot-olang_, Vis.

Uses.--The natives eat the little berries of this species, which are dark purple before and black after maturity, and use their juice for ink. The leaves are diuretic and refres.h.i.+ng; the bark alterant. In the bazaars of India the bark is sold commonly in pieces 1 long and as thick as the wrist; its taste is slightly sweet, color dark and the alterative dose of its decoction is 120-150 grams a day. In Concan they make a compound pill of the leaf-juice, powdered cubebs and camphor, to be dissolved in the mouth for ulcerated, bleeding or s...o...b..tic gums. The juice is also given internally for urticaria.

Botanical Description.--Small trees, 12 or more high, with leaves pinnate, oval, entire, alternate, glabrous, downy when young. Common petiole, 2 stipules at the base. Flowers monoecious. Staminate: calyx, 5 colored sepals; no corolla; filaments 4, coa.r.s.e, somewhat shorter than the calyx, the middle one thicker and 2-parted; anthers 10, 4 on the middle filament and two on each of the others. Pistillate: calyx and corolla same as staminate; nectary, 5 glandules on the base of the ovary. Fruit, a black berry seated within the calyx, crowned with 2 erect styles, 6 or 8 compartments each with a single seed.

Habitat.--Grows everywhere and is well known.

_Phyllanthus Niruri_, L.

_P. urinaria_, L.

Nom. Vulg.--_Hierba de San Pablo, de San Pedro_, Sp.

Uses.--This species is not used medicinally in the Philippines, but in India is given for its diuretic effect and has great repute in the treatment of genito-urinary diseases, dropsy and gonorrhoea. The infusion of the leaves of _P. Niruri_ with Fenugreek seeds is a highly prized remedy for chronic dysentery, mentioned by Ainslie. The leaves are bitter and tonic and in Bombay they are in common use in gonorrhoea to correct the acidity of the urine. Bruised and mixed with salt they make a sort of jelly frequently used as an application for itch; without salt the same is used for contusions.

The dose of the leaf juice of both species, for internal use, is 15 grams a day in divided doses.

A decoction of the entire plant well dried and powdered, is given for jaundice in doses of 5 grams a day.

The milky juice of the stem is useful in the local treatment of ulcers. The bruised root is employed in Concan for neuralgia.

Botanical Description.--_P. Niruri_ is an herb with straight stem. Leaves alternate, pinnate with stylet in place of the odd leaflet. Leaflets nearly oval, glabrous, 2 stipules at the base. Flowers monoecious, greenish, axillary; the staminate growing along the common petiole above the pistillate. Staminate: Calyx, 5 lanceolate, entire sepals; no corolla; 1 filament with 1 anther. Pistillate: Calyx and corolla as above; ovary free, 3 biovulate cells; style with 2 stigma-bearing branches. Fruit capsular, globose.

_P. urinaria_ may be distinguished by its sessile flowers and reddish stem.

Habitat.--Very common in Manila and all over Luzon.

_Jatropha Curcas_, L.

Nom. Vulg.--_Tuba_, Tag.; _Kasla_, Vis.; _Tawatawa_, Iloc. (Seeds called "English Physic Nuts" in India.)
