Chapter 15

The flowers are diuretic according to Endlicher; the bark is astringent; the leaves and the seeds are purgative, the latter yielding an oil which they use in India to stimulate the growth of the hair. Gibson considers the seeds diuretic and quotes two cases where abundant diuresis immediately followed by the application of a poultice of the bruised seeds over the pubis. In Concan they make a sort of extract from the wood and apply it to the yoke sores of the cattle to prevent the growth of maggots. This disinfectant action marks the plant as worthy of further experiment.

Rumphius is authority for the statement that the infusion of the leaves is used in cholera. The Chinese make vessels of the wood to preserve their drinking water at sea; the first and second waters are bitter and are thrown away, but after that the water has no disagreeable taste and is said to aid digestion.

It has been said that the wood was poisonous because at one time several workmen died from the effects of wounds caused by splinters of the wood, but the statement has not been confirmed by later cases and the deaths were most probably due to a septic infection independent of the chemical composition of the splinters.

R. Romanis has extracted a resin from the wood by alcohol; it is soft, and on distillation yields a crystalline body called by the author _tectoquinon_ (C_18_H_10_O_2_), on account of its resemblance to the quinons. It melts at 171° and volatilizes slightly at ordinary temperature.

Botanical Description.--A tree with leaves almost round, oval, entire, 30-60 centimeters by 20-40, the under surface covered with hoary down. Petioles very short, flattened. Flowers in panicles. Primary peduncle square. Calyx inferior, bell-shaped, very large when ripe, 5-cleft. Corolla white, longer than calyx, covered with a mealy substance, bell-shaped, 5-lobed. Stamens 5 or 6, inserted in the corolla. Filaments flattened, somewhat longer than the corolla. Anthers semi-globose, a yellow zone below and a black circle above. Ovary free, rounded, 4 locules each with 1 seed. Style same length as stamens. Stigma bilobulate. Drupe globose, woolly, spongy, depressed, covered by the membranous inflated calyx; contains one nut, very hard, 4 apartments each containing one seed.

Habitat.--The mountains of Morong and Tanay (of La Laguna Province) bear some specimens. Very common in the island of Negros and in Mindanao. It also grows in the Visayas, Mindora and Paragua. Blooms in September.

_Vitex trifolia_, L. (_V. repens_, Blanco.)

Nom. Vulg.--_Lagundi_, Tag.; _Gapasgapas_, Vis.; _Dangla_, Iloc.

_Vitex Negundo_, L. (_V. Leucoxylon_, Blanco.)

Nom. Vulg.--_Lagundi_, _Malawin_, Tag.

Uses.--Both species are used medicinally in the Philippines and both enjoy high repute. A variety of the first that seems to possess the same virtues is the _V. repens_, Blanco, called _lagunding gapang_ by the Tagalos.

_V. trifolia_ is regarded in India as the most powerful species and Bontius has extolled it highly, calling attention to the anodyne, diuretic and emmenagogue properties of the leaves. These are very effective applied in fomentation to rheumatic joints and their use is extensive both in India and the Malay Archipelago. A decoction of the leaves is used locally and as a vapor-bath in the treatment of beriberi. A large earthen pot is filled with leaves and water and brought to a boil; the pot is then placed under a chair in which the patient sits enveloped in a sheet or blanket. If necessary the pot may be removed 2 or 3 times, heated and replaced until abundant sweating is induced. An apparatus to conduct the steam under the chair would be much handier, but it is unsafe to place a small stove or lamp under the chair for fear of setting fire to the cloth.

In India and the Philippines there is a peculiar inflammation localized in the soles of the feet and characterized by an intense burning rather than pain, not described in the textbooks, but called by the natives "burning of the feet" ("quemadura del pié" or "ignipedites"); in our own experience and according to the consensus of the physicians of India, the application of these leaves 3 or 4 times a day to the soles of the feet has afforded marked relief. The leaves are heated in an earthen pot without the addition of water, and when sufficiently hot are applied and held in place by a bandage.

Dr. W. Ingledew states that the natives of Mysore (south of India) treat rheumatism and febrile catarrhs by steam baths of the decoction of vitex. A decoction of the leaves is in common use in the Philippines, Malay Islands and India as a bath for women in the puerperal state.

The dry leaves are smoked for headache and catarrh. According to creditable authority the application of the heated leaves in orchitis produces good results. The root is tonic, febrifuge and expectorant and the fruit nervine and emmenagogue according to the Sanscrit writer.

Botanical Description.--_V. trifolia_ is a small tree, 3-4 meters high. The fruit and leaves are said to emit the odor of rosemary. Leaves ternate. Leaflets oval, entire, hoary below, no secondary petioles. Flowers purplish in forked panicle. Corolla bell-shaped with palate. The lower lip 3-lobed, the middle lobe larger; upper lip smaller, 2-lobed. Stamens 4, free, didynamous. Ovary free. Style simple, with stigma-bearing lobules. Berry-like drupe, with 4-celled nut, one seed in each cell.

Habitat.--Common on the seashore. Blooms in June.

The _V. Negundo_ is a small tree like the preceding, but when it grows in the forest it develops to a tree of the first order, yielding a valuable building wood called _molave_ (Sp.) or more properly _molawin_. Leaves compound with 5 leaflets. Secondary petioles short. Flowers in dichotomous panicle. Fruit like that of the foregoing species.

_Clerodendron infortunatum_, L. (_C. fortunatum_, Blanco.)

Nom. Vulg.--_Kasupangit_, _Gubat_, Tag.; _Saling-wak_, Vis.

Uses.--The fresh juice of the leaves is used in India as a vermifuge, according to K. L. Dey; it is also used as a bitter tonic in malarial fever, especially of children. As a tonic and antipyretic it is certainly worthy of recommendation.

Dr. Bholanauth Bose calls attention to this plant as a good substitute for _Ophelia chirata_, DC. as a tonic and antipyretic.

The infusion of the bruised leaves (10 grams to water 300 cc.) is given up to 200 cc. a day in 3 or 4 doses; the tincture (leaves 60 grams, alcohol 90 %, 500 cc.) is given up to 10 grams a day in 5 or 6 doses.

Botanical Description.--A shrub with nearly round stem; leaves opposite, ovate, oblong; acute, entire, slightly downy. Flowers terminal in umbellate panicles, the umbellets opposite and each bearing 3 flowerets. Calyx bluish, long, tubular, somewhat expanded in the middle, divided in 5 parts. Corolla twice as long as the calyx, tube filiform, limb 5-lobed. Stamens didynamous, their lower parts grown to the tube of the corolla. Filaments longer than the corolla. Ovary conical. Style of same length as the stamens. Stigma bifid. Berry dry, quadrate, depressed, the shell hard, 4 grooves, 4 cells, each containing a seed.

Habitat.--Very common in Manila and in the forests.

LABIATÆ.

Mint Family.

_Ocimum basilicum_, L. (_O. Americanum_, Blanco.)

Nom. Vulg.--_Solasi_, Tag., Pam.; _Bonak_, Vis.; _Sweet Basil_, Eng.

_Ocimum gratissimum_, L. (_O. virgatum_ Blanco.)

Nom. Vulg.--_Lokoloko_, Tag., Pam.; _Kolonkogon_, Vis.

_Ocimum sanctum_, L. (_O. flexuosum_, Blanco.)

Nom. Vulg.--_Balanay_, Tag.; _Sacred Basil_, Eng.

Uses.--All three species possess a characteristic camphoraceous odor and are commonly grouped under the one name, _albahacas_ (sweet basil). Some natives call them _solasi_ and others _balanay_, but many are able to distinguish the various species correctly. All three have analogous properties, but the most widely used is the _O. basilicum_. These properties are stimulant, diaphoretic, and expectorant, and the infusion is used commonly for flatulent colic and painful dyspepsia. The dry powdered leaves of the _O. sanctum_ are taken as snuff by the natives of India in the treatment of a curious endemic disease characterized by the presence of small maggots in the nasal secretion; this disease is called peenash, and possibly exists in the Philippines though I have never encountered it.

Martins states that in Brazil they use a decoction of the mucilaginous leaves of the _O. gratissimum_ in the treatment of gonorrhoea and Dr. Waitz highly recommends a strong decoction of these leaves for the aphthæ of children, which he claims to have cured by this means after all European drugs had failed. This fact and the action of the snuff above mentioned, demonstrate the antiseptic properties of the plant, due doubtless to its abundant aromatic principles.

_O. basilicum_ contains a green essential oil, very aromatic, becoming solid; it is a sort of camphor (C_20_H_16_6HO, Raybaud) and crystallizes in 4-faced prisms.

All the plants are used to prepare aromatic baths for cases of atrophy and debility in children (Waitz) and for the treatment of rheumatism and paralysis.

Botanical Description.--_O. gratissimum_ is a plant 2-3° high, stem straight, downy. Leaves medium lanceolate, finely serrate from the middle upwards, with short hairs and transparent dots. Flowers in long terminal racemes. Calyx, upper lip horizontal, round; lower lip 3 pointed parts, the middle one subdivided in two. Corolla yellowish, inverted, one lip cleft in 4 obtuse lobes; the other longer, narrow, serrate. Stamens didynamous, 2 shorter. Anthers semilunar. Stigma bifid. Seeds 4.

The _O. Americanum_ has leaves lanceolate, ovate, acute, full of pores, somewhat downy. It is more fragrant than the other species and its flowers are bluish-white in racemes.

The _O. sanctum_ is the most sacred plant of the Hindoos, dedicated to Vishnu; its branches are wavy or cauliflexuous, leaves obliquely ovate, obtuse, serrate, nearly glabrous.

Habitat.--All species are very common and universally known.

_Coleus aromaticus_, Benth. (_C. suganda_, Blanco.)

Nom. Vulg.--_Orégano_, Sp.-Fil.; _Suganda_, Tag.; _Marjoram_, Eng. (The Sp. and Eng. names are incorrect.)

Uses.--The fleshy, aromatic leaves of this plant are bruised and applied locally for the bites of centipedes and scorpions. They are also applied to the temples and forehead for headache, held in place by a bandage. In Cochin China they are used in asthma, chronic bronchitis, epilepsy and other convulsive diseases. The juice of the leaves is a carminative and is given to children suffering with wind colic. Dr. Wight claims to have observed occasional intoxicating effects following its use, but Dymock states that he has never observed such effects. The plant contains a coloring matter, _colein_ (C_10_H_10_O_3_), red, insoluble in ether, soluble in alcohol, slightly soluble in water. On the addition of ammonia the solution changes to purple, then violet, indigo, green, and, finally, greenish-yellow.

Another species, the _C. atropurpureus_, Benth. (_C. grandifolius_, Blanco), well known in the Philippines by its common name _mayana_, is used in the treatment of bruises, the bruised fleshy leaves being the part employed; these leaves are downy and dark violet in color.

Botanical Description.--Leaves opposite, nearly sessile, cordate, obtuse, downy and very fleshy. Flowers in a quadrangular raceme, each group of these flowerets having a concave scale at the base. Calyx bell-shaped, 2-lipped; the upper lip longer and entire; the lower with 4 narrow teeth. Corolla a pale violet, 5 times longer than the calyx. Stamens didynamous, straight, longer than the corolla. Style bifid. Seeds 4.

Habitat.--Universally abundant.

_Rosmarinus officinalis_, L.

Nom. Vulg.--_Romero_, Sp.; _Rosemary_, Eng.

Uses.--This is one of the plants most valued by the Filipinos. Its infusion is used as an eye-wash for slight catarrhal conjunctivitis, applied 3 or 4 times a day. It is one of the aromatic plants used so commonly to bathe women in the puerperal state, and in vapor baths for rheumatism, paralysis and incipient catarrhs. The entire plant is a stimulant and carminative but little used internally; in atonic dyspepsia it has given good results taken in the same form as the infusion of manzanilla.

It contains a large per cent. of an essential oil which gives the plant its agreeable odor. This oil enters into the composition of "Cologne Water"; it is said to arrest falling of the hair and is a diffusible stimulant which may be given internally in doses of 3-5 drops. It is colorless and liquid when fresh, but in time becomes dark and viscid. It combines freely with alcohol and its density is 0.885.

Botanical Description.--A plant from 2 to 3° high. Leaves sessile, linear, obtuse, margins revolute, white-hoary beneath. Calyx tubular, 2-lipped. Corolla rose-violet color, gaping; the upper lip concave, 2-lobed; the lower lip longer, 3-lobed. Stamens, 2 fertile and 2 sterile. Style, same length as the stamens. Stigma simple. Fruit, 4 seeds in the depths of the calyx.

Habitat.--It is carefully cultivated throughout the Philippines.

_Anisomeles ovata_, R. Br. (_Phlomis alba_, Blanco.)

Nom. Vulg.--_Taligharap_, Tag.; _Jerusalem Sage_, Eng.

Uses.--The infusion of the leaves is bitter and aromatic and is used in catarrhal inflammations of the stomach and intestines and in intermittent fevers. Used as a vapor-bath it produces abundant diaphoresis, and the infusion given internally has a like effect. The leaves, when distilled, yield an oil which is used as an external application in rheumatism.

Botanical Description.--A plant 6° or more high. Root fibrous, trunk and branches enlarged at the joints. Leaves opposite, ovate, obtusely serrate, soft and downy. Flowers pink, verticillate, in opposite clusters around the stem, with several linear and hairy involucres at the base of each cluster. Calyx, 5 sharp teeth. Corolla, 2-lipped; the lower much larger, downy within, 3-lobed, the middle lobe larger and broader, notched at the extremity, and its borders turned downward; the other 2 lateral lobes very small, narrow; the upper lip much shorter and smaller, entire, enveloping the stamens. Stamens didynamous. Style about the same length as the stamens. Stigma bifid. Fruit, 4 small seeds.

Habitat.--Very common on the fields of Manila Province.

_Leucas aspera_, Spreng. (_Phlomis Zeylanica_, Blanco.)

Nom. Vulg.--_Pansipansi_, _Solasolasian_, _Karukansoli_, Tag.; _Pansipansi_, _Paypaysi_, Vis.

Uses.--The bruised leaves are applied to the bites of serpents or poisonous insects. In India they are similarly used. The juice of the leaves is very useful in the treatment of certain skin diseases, especially psoriasis.

Botanical Description.--A plant about 2° high, very well known to the natives. Leaves sessile, lanceolate, finely serrate and covered with short hairs. Flowers terminal, white, verticillate, with the characteristics of the mint family.

PLANTAGINACEÆ.

Plantain Family.

_Plantago erosa_, Wall. (_P. crenata_ and _media_, Blanco.)

Nom. Vulg.--_Llantén_, Sp.-Fil.; _Lantín_, Tag.; _Plantain_, Eng.

Uses.--The leaves of this popular plant are the commonest remedy in the Philippines for abscess of the gums. They are bruised and applied with a little lard over the swollen cheek. It is emollient and, in decoction, is used as a substitute for flaxseed.

Botanical Description.--This plant is so universally known that there is no fear of confusing it with others. It flourishes as a common weed in the U. S. as well as the Philippines.

NYCTAGINACEÆ.

Four-O'Clock Family.

_Mirabilis Jalapa_, L. (_M. longiflora_, Blanco.)

Nom. Vulg.--_Maravillas_, _Suspiros_, Sp.-Fil.; _Gilalas_, Tag.; _Four O'Clock_, _Marvel of Peru_, Eng.

Uses.--The root is purgative and possesses the same active principles, the same properties and is given in the same dose as jalap. According to the experience of Shoolbred, Hunter, W. O'Shaughnessy and Ainslie, its purgative action is weak and uncertain and therefore unworthy of use as a substitute for jalap. The bruised leaves are used as poultices to hasten suppuration, but according to Waring they are capable of causing dermatitis.

Botanical Description.--The flowers open toward the end of the day and close again at sunrise. The root is blackish and spindle-shaped. The stem smooth, branches forked. Leaves opposite, lanceolate-cordate, acute, somewhat downy along the borders and the upper surface. Petioles short. Flowers fragrant, almost constantly blooming, of different colors even in the same plant, terminal, in umbels. Pedicels very short. Calyx persistent, 5-toothed. Corolla superior, very long, its tube downy, funnel-form, limb 5-lobed. Stamens 5, longer than the corolla. Style longer than the stamens. Stigma globose. Nut small, black, globose, many-ribbed, full of a mealy substance.

Habitat.--Common in gardens.

AMARANTHACEÆ.

Amaranth Family.

_Amaranthus spinosus_, L.

Nom. Vulg.--_Kilitis_, _Orayi_, Tag.; _Ayantoto_, Pam.; _Kalitis_, _Tilites_, _Bayang-bayang_, Vis.; _Kuanton_, Iloc.; _Thorny Amaranth_, Eng.

Uses.--The entire plant is emollient and its principal use is as a poultice for inflammations, bruises, etc. The decoction of the root is diuretic and antiphlogistic and is used in Mauritius (30 grams root to 750 cc. water) as an internal remedy for gonorrhoea; indeed it is there regarded as a specific for that disease, checking the discharge and the "ardor urinæ." It should be continued till the cure is complete.

The bruised leaves are used locally for eczema.

Botanical Description.--A plant 2-3° high of a reddish color. Leaves alternate, lanceolate, broad, notched at the apex, wavy, glabrous. Petioles with a pair of spines in their axils. Flowers small, yellow-green, in round axillary clusters and in long terminal spikes. The pistillate flowers are sometimes separated from the staminate, sometimes mixed with them in the lower part of the spike. Staminate: No corolla, calyx 2-5 parts, stamens 4-5. Pistillate: Style and stigma 2 or 3, otherwise the same as the staminate. Seed vessel with 1 seed.

Habitat.--Common in all parts. Blooms in October.

_Achyranthes obtusifolia_, Lam. (_A. aspera_, Blanco.)

Nom. Vulg.--_Hangor_, _Hangot_, _Dokotdekot_, _Libay_, Tag.; _Angod_, Pam.

Uses.--The plant has astringent and diuretic properties; the latter were observed by Dr. Cornish, who communicated the facts to Waring, calling special attention to the good service the drug had afforded him in dropsy. Other physicians in India have confirmed these observations of Cornish. The decoction is made of 60 grams of the entire plant to 750 cc. water, boiled till reduced one-half and strained under pressure. Dose, 60 cc. every 2 hours till diuresis is induced.

The ashes of this plant, like those of the _Amaranthus spinosus_, L., contain a large quantity of potassa, and are used for washing clothes; on this account it has received its Sanscrit name _Apamarga_ (the washer). The ashes are also mixed in an infusion of ginger and given internally in dropsy.

The flowers are bruised and applied to the bites of snakes and other poisonous animals. In India there is a superstition that carrying these flowers about the person will keep off scorpions.

Botanical Description.--A plant about 3° high, the stem angular and downy. Leaves opposite, downy, clasping the stem, lanceolate, very obtuse and wavy. Flowers bent downward in a long spike bearing many flowerets. Calyx, 5 tough scales. Corolla wanting. Nectary much smaller than the calyx, monophyllous, 5-lobed. Stamens 5. Ovary top-shaped, upper part somewhat concave. Style same length as stamens. Stigma coarse, bifid. Fruit, a seed covered with 2 membranes, one enveloping it completely, the outer one adherent in only one part.

Habitat.--Common in Luzon. Blooms in November.

CHENOPODIACÆ.

Goosefoot Family.

_Chenopodium ambrosioides_, L.

Nom. Vulg.--_Alpasotes_, Sp.-Fil.; _Pasotis_, _Apasotis_, Tag.; _American Worm-seed_, _Mexican Tea_, Eng.

Uses.--This plant is a native of Mexico. It has a peculiar, somewhat offensive odor and an acrid, aromatic taste due to an essential oil resembling peppermint (?). According to Padre Mercado, "When the seeds are taken with wine, sensation is so dulled that the drinker may be whipped without feeling the lashes, and even if put to the torment, does not feel it." These properties, if true, make this plant one of the most useful in the Philippines. The entire plant is stimulant. The infusion, given internally, causes sweating, excites the circulation, is diuretic, tonic, stomachic, and useful as well as an antispasmodic in nervous troubles. The leaves are employed in making the infusion, 8 grams to 200 of boiling water. It is widely used in bronchial catarrhs and in asthma on account of its sudorific and expectorant action. It seems also to possess emmenagogue properties. The seeds yield on distillation a yellow essential oil with a strong and disagreeable odor, density 0.908. Both seeds and flowers are vermifuge, and are used as such in Brazil in doses of 8 grams in infusion or with an equal dose of castor oil. The anthelmintic dose of the essential oil is 5-15 drops with powdered sugar.

Rilliet and Barthez recommend the following potion for infantile chorea:

Leaves of chenopodium 4 grams. Water 500 grams.

Make an infusion and add syrup of orange flowers 50 grams. Dose, several tablespoonfuls a day.

Botanical Description.--A plant 2° high; stem beset with hairs, many-angled. Leaves lanceolate, varying from entire to cut-pinnatifid. Flowers green, sessile, axillary, in small clusters. Calyx 5-parted. Corolla wanting. Stamens 5. Filaments flattened, inserted near the center of the flowers opposite the parts of the calyx. Anthers in 2 globose parts. Ovary superior, globose, depressed, unilocular, uniovulate. Style none. Stigmas, 2, 3 or 4, short, divergent. Fruit a lenticular seed covered by the membrane of the ovary.

Habitat.--Common in gardens and fields. Blooms in May.

ARISTOLOCHIACEÆ.

Birthwort Family.

_Aristolochia Indica_, L.

Nom. Vulg.--_Timbangan_, _Malaubi_, Tag.; _Indian Birthwort_, Eng.

Uses.--The root has a wide use in medicine in the Philippines; it is bitter, of a nauseating odor and has the reputation of being a powerful antidote for the bites of poisonous serpents and insects. It has further use in the treatment of malarial fever, in dyspepsia, and in the flatulent colic of teething children. It is regarded as tonic and emmenagogue. In various forms of diarrhoea it appears to be effective and Dr. Gibson states that it is useful in intestinal disorders. In the Philippines it is not only given internally but also externally applied over the abdomen, mixed with hot cocoanut oil (10 grams of the powdered root to 100 oil).

The first Portuguese settlers in India called the drug "Cobra Root," because the natives regarded it as an antidote for the bite of the terrible "Cobra da Capello." This reputation, however, seems not to have been deserved, judging from the fearful mortality in India and Ceylon due to the bite of the cobra.

Dr. Imlach, a surgeon of Singapore, states that in one season in one collectorate, Shikapore, no less than 306 cases of snake bites were officially reported, the mortality being 63, or about 20.58 per cent. Other reports make it safe to conclude that in the entire province during the year no less than 300 deaths were due to this cause alone. Dr. Waring believes that if an antidote for snake bite exist in the vegetable kingdom it will most probably be found in the natural order Aristolochiaceæ.

In North India this drug is used as emmenagogue and anti-arthritic, and in Banda for intermittent fevers and intestinal disorders. The juice of the leaves is emetic. The dose of the powdered root is 3-5 grams daily.
