The Medicinal Plants of the Philippines

Translator’s Preface.

This translation was undertaken with the especial object of facilitating the study of the native medicinal plants by the numerous medical officers stationed at small posts throughout the Philippines. In order to aid in the recognition of these plants, the botanical descriptions have been revised to the extent of adding, where possible, the size and shape of the plant, English name, length of leaves, color of flowers, etc., in many instances supplying the entire botanical description where it had been omitted on account of general familiarity with the plant. Comparing the few analyses that I have had an opportunity to make with corresponding ones in the native works from which Dr. Tavera has taken his botanical descriptions, I am impressed with the necessity for a revision of the Botany of the Philippines. However, as the therapeutic properties of the flora are of foremost interest to the medical profession I have not hesitated to publish the book in its present form as an entering wedge, leaving to those better fitted the great work of classifying the flora of these islands in accordance with modern botanical science.

Dr. Tavera has faithfully described the Malay and Hindu therapeutics of the present day, enriching his description by observations founded on a long practice in Paris and in his own native Luzon. From this potpourri of scientific therapeutics and ignorant, superstitious drugging the interested physician will elicit not a few useful data concerning the treatment of disease in the tropics, and at the same time gain a more intimate knowledge of both the people and plants of our new Asiatic possessions.

I take this occasion to gratefully acknowledge my obligations to Mr. A. P. Tonielli, stenographer and translator of the Supreme Court of the Philippines, for typewriting the manuscript of this translation.Jerome B. Thomas, Jr.Manila, P. I.

Preface.

Commissioned by His Majesty’s Government to study the medicinal plants of my native country, I returned there and spent two years in collecting data regarding the use that the Filipinos make of their plants in the treatment of disease. At the same time I collected and carefully preserved some with the purpose of taking them to Europe, to study their chemical composition in the laboratories of Paris under the direction of the eminent men who had been my instructors in medicine.

The work I did in the Philippines was preliminary, a preparation for the more extended study of the subject which I wished to make in Paris, where I went with my notes and collection. Unfortunately, upon leaving Manila, I confided the mounting and pressing of my plants to an inexperienced person who stupidly placed in the midst of them several succulent tubers which decomposed during the voyage and spoiled the other plants. At the same time I received in Paris an important collection of the vegetable drugs of the Philippines, sent by my friend the pharmacist, M. Rosedo Garcia, and destined for the World’s Fair of 1889. I opened with great pleasure the wood and zinc box in which the collection came, anticipating that I should be able to carry out my plan of study and at the same time win for my friend, Garcia, a well-deserved premium. Imagine my disappointment upon finding that, by an unfortunate coincidence, his plants had arrived in the same condition as mine, having also been packed with tubers of ubi, gabi, etc., and several cocoanuts which had decomposed.

Many times since then I have tried to obtain from Manila, through exchange or payment of money, a similar collection, but have been unable to secure a single leaf of the plants I so desired. If in the future I have the good fortune to procure any, I shall make a study of those at hand and publish the results.

I herewith publish the results of my investigations and experiments in Manila, where, especially in the neighboring towns of San Mateo and San Miguel, I often had opportunities for using, with good results, the plants of which this volume treats. I may add that in spite of the limited means at my disposal in Manila and the short time left me by my regular occupations I was able to conduct a few laboratory experiments owing to which this work contains some personal observations reinforcing those quoted from medical literature.

The flora of the Archipelago is known to-day through the works of Fathers Blanco, Llanos, Fernandez del Villar and Naves, and of the engineers Jordano, the brothers Vidal and Soler and others who have brought such honor to Spanish science, preparing the way for the study of the therapeutic and industrial applications of that wonderfully rich plant life with which our islands have been endowed. Their works help us to recognize the plants whose medicinal virtues are herein described and it is to them I owe the botanical descriptions in this treatise.

Father Blanco, in describing certain plants, mentions their medicinal uses in the Philippines, but his descriptions are few and very deficient as one would expect in a work of the scope of his Flora. A Jesuit of some reputation, Father Clain, published in Manila in 1712 a book entitled “Remedios fáciles para diferentes enfermedades?” in which he speaks of the medicinal virtues of some of the indigenous plants, almost the same ones that appear in another work, a frank and pleasing little treatise written by Father Santa Maria. Father Mercado is the only one who has written a special treatise on the subject and his manuscript remained unedited until the Augustinian Fathers of Manila published it in the last edition of Father Blanco’s “Flora”; but neither this work nor those of Clain or Santa Maria are useful to a physician, nor are they as accurately written as works of a scientific character should be. From time to time superficial articles have appeared in the Manila papers regarding the virtues of some plant or other and these books and articles comprise the whole literature on the subject up to this time.

Some physicians regard with small favor the therapeutic application of plants by the Filipino “herb-doctors” (curanderos) as being entirely empirical. This disparagement is unjustified because in all the most rational and scientific remedies that we make use of, the first step towards the final development of their relative position among remedies is due to empiricism which is founded on daily experience, on observation of results obtained in specific cases, facts that are handed down from father to son for generations. The scientific explanation is lacking, but those first ideas frequently owing their origin to chance, or, perhaps, to superstition, have often been based upon the observation of facts which, although fortuitous, are none the less positive.

Many of the plants mentioned in this book are official in the Pharmacopœia of India and we see no reason why their use should be proscribed in the Philippines. Filipino physicians not only can but should employ many indigenous plants in their therapeutics; in many instances they would find them more useful than the exotics, which are not always fresh and are commonly reduced in strength by long keeping or damaged by some circumstance of voyage or climate. The price is another argument in favor of the use of native drugs. If the pharmacists would prepare extracts and keep on hand the crude drugs most in demand the public would gain a great advantage and the druggists be well repaid for their labor. Physicians and pharmacists will surely understand these advantages and when finally one considers that the patients generally prefer to be treated with native plants, I feel justified in the hope that their use will spread rapidly in the Philippines.

To employ therapeutically the drugs described in this work is not to experiment “in anima vilis,” as some would have us believe. To experiment is to employ unknown remedies of unknown virtues and properties.

In this treatise I am not attempting to fix the indications for this or that product, but simply make known the diseases in which the Filipinos and the natives of other countries employ the products. Any physician has a perfect right to prescribe these drugs, as have also the “curanderos” and even the laity, with this difference, however, that the physician is capable of observing results and guiding himself by the physiologic action of the drugs. His knowledge of the physiologic and anatomo-pathologic problems of the human body, will enable the physician to make scientific inferences that would be hidden from the common “curandero.”

As neither the Manila nor the provincial physicians keep these medicinal plants in stock, with the exception of those that are official in the European and American pharmacopœias, it will be necessary for the physician who wishes to use them, to busy himself with seeking them and laying in a sufficient stock to serve him when the opportunity presents itself. It is necessary to preserve them by drying and this is best done by exposing them several days to the fresh air in a dry place—for example, the corridors of the house—being careful not to expose them to the rays of the sun, in which latter event the fleshy and juicy plants which do not desiccate rapidly, putrefy or ferment.

A convenient way to get them is to visit the Binondo Square where there has been market for native drugs from time immemorial. The gardeners from the neighboring towns, especially those from Pasay and Singalon, regularly offer the plants for sale and will undertake to supply you with any that may not be on hand. Inasmuch as the common names of the plants lead to many mistakes and much confusion, it is indispensable to acquaint one’s self with the description of the plant and be sure that the actual product conforms in all respects to the description. For this purpose it is well to obtain flowering specimens, and bearing this fact in mind I have been careful to indicate the flowering season of each plant. By making excursions to the towns of San Mateo and Angono I have obtained an abundance of whatever I sought and at the same time have learned by talking with the mountaineers and “curanderos,” what uses they make of their plants. The “curanderos” know a great deal concerning these uses, but become very reticent as soon as they are questioned about them. Whether it is dread of ridicule or selfishness or fear that silences them, the fact remains that it is no easy matter to glean any useful facts from them. And yet by tact and friendliness one may elicit much more information from them than first impressions would lead one to hope.

Leaves should be gathered when fully developed, rejecting the old, dried and worm-eaten ones.

The best time to gather bark is one month before the period of inflorescence, when it is rich in sap. The flowers are best gathered when about half expanded. The fruit is gathered green or ripe according to the active principle sought. The seeds should always be mature.

Not all parts of the plant are equally provided with the active principle which may be localized in the root or the flower; or distinct principles may exist in different parts of the same plant. Therefore the part indicated, and only that part, should be employed.

In the root the active substance usually resides in the bark, sometimes in the parenchyma that envelopes the woody tissue and rarely in the woody tissue itself, as, for example, in “rhubarb” and “pareira brava.”

The stem bark is also a frequent seat of the active principle, of which the outer portion contains the greater amount, according to the valuable experiments of Howard.

Some plants owe their therapeutic importance to their wood, others to their leaves or flowers, and regarding the localization of the active principle in these parts we have nothing especial to indicate. The fruit, however, may have a pericarp consisting of mucilage, starch, sugar and gum, etc., while the seeds contain fatty matter, fixed or essential oils or alkaloids, as is the case with coffee and cacao. In view of these facts, we repeat that it is indispensable to use that part of each plant which I have indicated as applicable to a determined case or condition.

I earnestly hope that the physicians and pharmacists practising in the Philippines may undertake investigations and experiments regarding the therapeutic properties of the plants of my native land, and that my endeavors may have acted as a stimulus or inspiration to the loyal and earnest study of the subjects that are now awakening such interest, not only in Europe and America, but in India and Japan.

I should be pleased to receive notes, plants or reports of researches from any one interested in the subject matter of this book, and I shall consider it a pleasure, as well as a duty, to devote my forces, small as they may be, to aiding any one who may do me the honor to claim my assistance.T.

Explanation.

For the common words of the different Filipino dialects I have adopted the orthography which in my various treatises on those dialects I have demonstrated to be the easiest, most rational and convenient. I should be inconsistent as to my own theories and convictions if I continued to follow the old form of spelling. For the benefit of those who are not familiar with the matter I will state that the consonants are pronounced as follows:galways as in get.hgutturalized aspirate.kas in English.walways as initial w in English, win, wan.as ng in sing, hung, etc.g̃

Abbreviations.

Dicotyledonous, Polypetalous.

Dilleniaceæ.

Tetracera macrophylla, Vall. (T. monocarpa, T. sarmentosa, Blanco.)

Nom. Vulg.—Malakatmón, Tag.

Uses.—The wood of malakatmón is one of the best known and 1popular drugs of the Binondo market place. It is used as an infusion internally in the hæmoptysis of consumptives, and externally in the treatment of sore throat, its action being due to the large amount of tannin it contains. It is also employed in Malabar in the form of an infusion of the leaves of the species, T. Rheedi, to treat sore throat, mixing it with a decoction of rice called cange.

The Filipinos do not distinguish this species from the T. Assa.

Both are called malakatmón, and are employed indiscriminately to accomplish the same results. The silicious concretion obtained from the leaves is used as a polish in the form of polish paper.

Dose.—In infusion for internal use, 4 grams of wood to 1 liter of water; as a gargle, 10 to 15 grams to the liter.

Botanical Description.—A shrub with leaves alternate, oval, serrate, finely dentate with very short and stiff hairs. Flowers of a strong, rather agreeable odor, axillary, in panicles. Calyx, 4 sepals. Corolla, 4 petals. Stamens indefinite, expanding at the upper end and bearing 2 anthers. Carpels 3, with ovules indefinite in two series. Seeds with red arils.

Habitat.—In the vicinity of Manila. Blooms in July.

Magnoliaceæ

Magnolia Family.Illicium anisatum, L.

Nom. Vulg.—Anis estrellado, Badiana, Sp.; Sag̃ki, Tag.; Star Anise, Eng.

Uses.—Although this plant does not grow in the Philippines, the use of its fruit is so common there that it demands a place in this work. It is employed chiefly as a condiment in the preparation of food, and its essential oil is used to prepare the native “anise cordial” by mixing it with alcohol obtained from the palm or from sugar cane.

The decoction of the fruit is given after meals as a tea-like beverage, to aid digestion or for its carminative effect in flatulent colic.

Star anise has an aromatic taste, slightly bitter and acrid, and a very marked perfume of anise which with its star-like form gives the plant one of its names. It is a very useful stimulant, tonic, stomachic and carminative.

It is official in all Pharmacopœias and the pericarp is the part employed.

The dose is from 1 to 2 grams to 100 of water in infusion, to be taken in one draught.

According to Schlegel it contains the following substances: An essential oil 4.675; a green waxy material which melts at 51°, a resin, a gum and saponin. The essential oil is (almost) identical with that of anise from which it is impossible to distinguish it chemically. The only difference is that the former has a blander odor and solidifies at 1°.25 instead of 10°, as does the oil of anise.

Botanical Description.—The plant grows in the mountains of Yunnan, China, and in Tonquin. The part used in the Philippines is the fruit, being indeed the only part known here. This is composed of 8 woody follicles arranged about a central column in the form of a star. These follicles open at maturity and reveal the seeds, which are shining, smooth, ovoid, hard, of a pretty chestnut-red color. In the Philippines they are sold even in the smallest food-vending shops.Michelia Champaca, L.

Nom. Vulg.—Tsampaka, Sampaka, Tag.; Champaca, Fil.-Span.

Uses.—The bark of the trunk is well known as a febrifuge and emmenagogue in India. It is slightly bitter and aromatic. Dr. H. Folliat has used it with success in the Island of Mauritius in the treatment of the common intermittent fevers; he administered the infusion (bark 30 grams, water 600 cc.)—or the decoction (bark 30 grams, water 1,200 cc.); boil till reduced to 600 cc.—giving a wine-glassful every hour just before and after the paroxysm.

An astringent decoction made from the leaves is used as a gargle in sore throat. The root is emmenagogue and the seeds are used in the treatment of anal fissure.

Dr. Hooper has found the following substances in the bark of the Champana: a volatile oil with a pine-like odor; a fixed oil, insoluble in alcohol, melting at 15° and forming soap with soda; a resin extremely bitter, acrid, brown in color; tannin; sugar; a bitter principle, albuminoids, coloring matters, mucilage and starch.

Botanical Description.—A tree 15–18° high; leaves alternate, 6 × 2′, stipulate, simple. Flowers fragrant, saffron-colored, hermaphrodite, solitary and axillary. The receptacle, conical at its base, becomes narrow, lengthens and then enlarges, forming a column which is bare at its narrow part. At its base is inserted the perianth composed of 6 overlapping leaflets arranged in two series. Stamens indefinite, fixed in the base of the column of the receptacle on the superior portion of which are inserted the ovaries which contain many ovules arranged in two vertical series.

Habitat.—Common in all parts (of the islands).

Anonaceæ.

Custard-Apple Family.

Artabotrys odoratissimus, R. Br. (A. hamatus, Bl.; Uvaria Sinensis and Unona uncinata, Blanco.)

Nom. Vulg.—Ilag̃-ilag̃ de China, Sp.-Fil.; Alag-̃ilag ̃Son-son, Tag.

Uses.—A decoction of the leaves of this species is used to treat cholera in some of the islands of the Malay group; in the island of Java they use for the same purpose a decoction of the leaves of the species A. suaveolens, Bl., which is commonly called Susog ̃Damulog in the Pampanga dialect. The active principles of these plants are so powerful that one must beware of giving a large dose, as hemorrhages, nervous phenomena and abortion may follow.

Botanical Description.—A tree 15–18° high with leaves alternate, lanceolate, glabrous, and petioles very short. Flowers very sweet, axillary, solitary. Petals 6, fleshy, concave at the base. Stamens indefinite, closely packed, overlapping. Peduncle curved like a crook.

Habitat.—Cultivated in gardens.

Anona squamosa, L. (A. tuberosa, Rumph.)

Nom. Vulg.—Ates, Tag.; Custard Apple, Eng.

Uses.—The fruit of the mature ates is edible and is one of the most delicious that grows in the Philippines; its white and delicately perfumed pulp has a delicious flavor. The unripe fruit is exceedingly astringent. The fermented juice of the ripe pulp is used in certain parts of America to prepare a popular drink. The powdered seeds make a useful parasiticide especially when used on the scalp, but it is necessary to avoid getting any of the drug in the eyes on account of its irritant effect.

Botanical Description.—Tree 8 or 9° high with leaves alternate, oblong, the edges pubescent. Flowers greenish-yellow, axillary, solitary; peduncle not curved. Petals 6, convergent. Stamens crowded, indefinite. Fruit fleshy, covered with scales or rather rounded tubercles; beneath is the white and fragment pulp, covering the long-oval seeds.
