_Randia dumetorum_, Lam. (_R. longispina_, DC.; _R. aculata_, Blanco; _R. stipulosa_, Miq.; _Gardenia spinosa_, Blanco.)

Nom. Vulg.--_Sinampaga_, Tag.

Uses.--The fruit is used in some parts of India to kill the fish in ponds and sluggish rivers, the same use to which they sometimes put the "Cocculus Indicus." It is prescribed as an emetic by the Sanscrit and Arabic medical authors of India. Mooden Sheriff ascribes its emetic properties to the pulp alone, the epicarp and seeds being inactive according to his authority. It is a subst.i.tute for ipecac even in the treatment of dysentery in which case the decoction of the trunk bark is also used.

The dried and powdered pulp is given in dose of 2.50 grams as an emetic and 1-2 grams as an antidysenteric. To prepare the fresh fruit for administration as an emetic, mash 2-3, macerate 15 minutes in 150-200 grams of water and filter. It acts in a few minutes and its effect may be hastened by giving tepid water or tickling the fauces.

Botanical Description.--A shrub with straight, th.o.r.n.y stem, leaves sessile, springing from the buds, occurring in threes, obtusely lanceolate, entire, glabrous. Flowers solitary or in pairs, very fragrant. Calyx gamosepalous with 10 toothlets. Corolla twisted, arched, cleft in the middle, throat nude, limb slashed in 5 large glabrous parts. Stamens 5. Filaments short, inserted on corolla. Style 1. Stigma bifid. Fruit inferior, about the size of a crab apple, crowned by the remains of the calyx, smooth, yellow, fleshy, 1-celled with many seeds.

Habitat.--On the coast of Luzon. Blooms in May.

_Ixora coccinea_, L. (_I. bandhuca_, Roxb.)

Nom. Vulg.--_Santan_, Tag.

Uses.--The handsome red flowers are used in decoction for haemoptysis and catarrhal bronchitis. Both root and flower are astringent and are given for dysentery. In Concan they cook 2 "tolas" (13.60 grams) of the flowers in lard, together with coriander and "mesua ferrea,"

add a little candied sugar and divide the ma.s.s into large pills to be given twice a day.

The fresh root in the form of an alcoholic tincture has been recommended by Deb for dysentery, the dose 2-4 grams in an appropriate potion. The tincture of the fresh plant is prepared by macerating 126 grams of the fresh root 15 days in 473 grams alcohol. The plant has been used in intermittent fevers and various skin diseases.

Botanical Description.--A shrub cultivated in all gardens, 6-8 high. Leaves oval, entire, glabrous. Flowers in terminal umbels, white, pink or red. Corolla tubular with limb cleft in 4 rounded lobes. The plant is so well known that further description would be superfluous.

_Coffea Arabica_, L.

Nom. Vulg.--_Cafe_, Sp.; _Coffee_, Eng.

Uses.--The infusion of roasted and ground coffee seeds const.i.tutes a beverage of Arabic origin, but now common all over the world. In the Philippines, where a few years ago the coffee plant was only cultivated in gardens, the harvest has a.s.sumed such proportions that it now const.i.tutes one of the greatest sources of agricultural wealth. Its use is becoming more general every day and the discovery of its alkaloid "caffeine" the therapeutical use of which is also steadily increasing, has given new importance to the seed on account of its increasing demand in the drug trade. When newly harvested its taste is not very agreeable, for it needs considerable time--2 or 3 years--in which to dry completely, before it acquires the aromatic properties and the savor of which it is susceptible. General Morin relates an incident of having drunk a delicious infusion of coffee made from authentic Moka that had been kept for fifty years, of course under ideal conditions of preservation.

In civilized countries coffee is an article of prime necessity as a food; here we shall consider it therapeutically under two heads, as a tonic-stimulant and as an antiseptic. As caffeine is the principle that acts upon the heart we shall consider the cardiac properties of coffee under the head of that alkaloid, so important that it may best be studied separately.

There are two preparations of coffee, the decoction used by the Arabs and the infusion, used in Europe and adopted in the Philippines. The decoction forms a tonic and aromatic drink devoid of any excitant properties, but the infusion is highly excitant and should not be taken in such large amounts as the decoction, for its action may be powerful enough to cause headache, nausea, trembling of the extremities and disorders of vision and hearing. These phenomena however are not dangerous and rapidly subside as soon as the urine eliminates the substances that cause them.

Infusion of coffee stimulates especially the cerebral functions and the circulation; as to its digestive properties, opinion is divided but it is more probable that it lacks them and that coffee taken after meals owes its reputation as a digestive aid to two distinct factors--the temperature and the sugar. Without doubt it exerts an anaphrodisiac action, on account of which the ill.u.s.trious Linnaeus called it the "drink of eunuchs." This action seems incompatible with the fact that the Arabs, who are so much given to the abuse of the pleasures forbidden to eunuchs are most addicted to the use and abuse of coffee. The explanation rests in the form in which they consume their coffee, namely the decoction, which is free from the sedative principle of the seed, that undoubtedly resides in the aromatic ingredient "cafeol."

Coffee is contraindicated in hysterical and nervous persons, in children and in those who suffer with insomnia or palpitation. It counteracts sleep and coma, being very useful in poisoning by opium or its alkaloids. Its stimulant action is as rapid as that of alcohol. On several occasions it has yielded me marked results when given by stomach or by enema in cases of nervous and cardiac depression. Indeed it is a remedy that I cannot recommend too highly and each day leaves me more convinced of its therapeutic activity and certainty.

Attention has only lately been directed to the antiseptic property of coffee though we have long been availing ourselves of that property without knowing it; this is true of many other medicinal agents, indeed of all that the modern studies of bacteriology have presented to us as antifermentives and microbicides. Roasted coffee in powder form gives good results if dusted over ulcers and gangrenous sores, rapidly improving their appearance and destroying the foetid odor. It corrects the unhygienic properties of non-potable water and therefore enters into the army and navy ration of nearly all the nations of Europe. In epidemics of disease every physician should advise its use in mild infusion as a regular beverage.

Dr. Luderitz, experimenting in the Hygienic Inst.i.tute of Berlin, reported that no bacteria could resist the action of coffee in infusion. He attributed this action not only to the tannin, which is present in high percentage, but princ.i.p.ally to the empyreumatic substances formed by the roasting. The caffeine takes no part in this action. Dr. Luderitz exposed the coffee to the open air for six days and found it free from bacteria at the end of that time. Whatever may be the explanation of its activity the fact remains that coffee is highly antiseptic, and this should be kept in mind by physicians not only because it is everywhere easily obtained and an infusion easily prepared, but because it in addition possesses the great advantage of being nontoxic.

The chemical a.n.a.lysis of the seed is as follows:

Cellulose 34.000 Water 12.000 Fatty matters 10 to 13.000 Glucose, dextrin, undetermined acid 15.500 Legumin, caffeine 10.000 Chlorogenate of caffeine and pota.s.sa 3.500 to 5.000 Alb.u.minoids 3.000 Caffeine, free .800 Essential oil, solid .001 Essential oil, liquid .002 Mineral substances 6.697

Caffeine, the only one of the ingredients that interests us, was discovered by Hunge in 1821 and recognized as an alkaloid by Herzog. It also exists in tea, formerly known as "theine" which is now known to be identical with caffeine; both are expressed by the formula C_8_H_10_N_2_O_2_+H_2_O. It crystallizes in fine, silky needles, is colorless, odorless and slightly bitter.

It is considered a subst.i.tute for digitalis, especially valuable as a diuretic and where cerebral anemia exists. Germain See values it as a preventive medicine, acting princ.i.p.ally upon the heart and thus preventing fatigue; with this end in view he advises its use before long marches, violent exercise and all conditions where the heart will be called upon to do a greatly increased amount of work. Dose 0.25 gram to 1 or 2 grams a day given by stomach or hypodermic injection.

Caffeine is also useful in headache, neuralgia, and asthma and as a general tonic. For the latter action it is best given in pill form, 0.02-0.04 gram a day, with the extract of cinchona or other bitter tonic.

"Etoxy-caffeine," which is caffeine in which an atom of H has been replaced by the C_2_H_5_O, exists as white, needle-like crystals, slightly soluble in water; it is narcotic and sedative to the cerebro-spinal system. In doses of 0.24 gram it is useful in headache.

_Morinda citrifolia_, L.; variety: _bracteata_, Hoock, Jr.

(_M. ligulata_, Blanco.)

Nom. Vulg.--_Bankundo_, _Pankundo_, _Bangkuro_, _Nino_, _Kulit_, _Tumbongaso_, _Lino_, _Mambog_, _Takpus_, Tag. and Vis.; _Taliantar_, Pam.; _Apalot_, Iloc.; _Indian Mulberry_, Indo-Eng.

Uses.--In the Philippines, as well as in India, the root of the plant is widely used as a red dye. As a medicine the Tamul physicians use it in decoction to treat diarrhoea and dysentery. The fruit is emmenagogue and perhaps aperient. In Bombay the mashed leaves are applied to wounds and ulcers to hasten cicatrization; they also use the decoction internally as a febrifuge and tonic, 10 grams to 500 of water, a winegla.s.sful twice a day.

The root bark contains a crystalline substance called by Anderson _morindin_, C_28_H_30_O_15_. It is a glucoside and exists in the form of yellow needles, soluble in alcohol and in cold water, insoluble in ether; dissolves in alkalies producing an orange-red color.

There is another species, _M. tinctoria_, Roxb.; _M. Royoc_, Blanco, called in Tagalog _Tumboung aso kapay_, the roots of which are used by the Filipinos for the same purposes as the leaves of the former species; the dose, 8 grams a day. The powder is also applied to ulcers and sores, especially those of gangrenous aspect.

Botanical Description.--A small tree 11 or more feet high, branches opposite, quadrate at the extremities. Leaves opposite, oval, oblong, smooth, entire, glabrous. Petioles very short, with 2 broad, lanceolate stipules curved outward. Flowers white, opposite the leaves, fixed on globose, solitary receptacles from which spring the flowerets. Calyx proper, very short, monophyllous, a lanceolate leaflet springing from the border. Corolla tubular, woolly inside about the middle, with 5 lobules. Stamens 5, inserted on the walls of the corolla. Anthers thin, inc.u.mbent. Pistil somewhat longer than the corolla. Stigma cleft in 2 laminae. Fruit: the receptacle of the flowerets ripens to a globe bristling with the remains of the calyces, like a berry covered with many smaller ones, each containing 2 monospermous, quadrangular seeds.

_M. tinctoria_, Roxb., is a climbing shrub with leaves opposite, ovate, keeled; petioles very short; flower and fruit like the foregoing species.

Habitat.--In Luzon and, especially the M. tinctoria, in Malinta, Calauan and Tanauan.

_Paederia foetida_, L. (_P. sessiflora_, DC.)

Nom. Vulg.--_Kantutan_, _Kantutae_, Tag.; _Lilitan_, _Tae-tae_, Vis.

Uses.--The foetid odor of this plant has suggested both the technical and common names for it. The natives regard it as a cure for rheumatism. The root is emetic. The leaves, boiled and mashed, are applied to the abdomen in retention of urine; the decoction of the leaves is used for the same purpose and also has some reputation as a solvent for vesical calculus. For fever, cloths soaked in the decoction are applied to the head, the same preparation being given internally at the same time.

Botanical Description.--A slender, twining plant with leaves 3'

by 1', opposite, oval, acute, entire, long petioles and caducous stipules. Flowers dark rose color, in compound axillary and terminal cymes. Calyx of 5 persistent lobules. Corolla tubular, p.u.b.escent, 5 lobules. Stamens 5, free. Ovary inferior, flattened, 2 uniovulate locules. Style with 2 stigma-bearing branches.

Habitat.--Luzon, Mindanao, Cebu, Panay.
