Part 12

Habitat.--Mandaloya Tayabas, Iloilo.

Gossypium herbaceum, L. (G. Indicum, Lam.; G. Capas, Rumph.)

Nom. Vulg.--Algodón, Sp.; Bulak, Tag.; Cotton, Eng.

Uses.--The root bark is antiasthmatic, emmenagogue, and according to Daruty is a substitute for ergot in uterine hemorrhage. The leaves are used in bronchial troubles and the seeds are sudorific. The negroes in the United States use the root bark in large doses as an abortifacient; but a dose of 60 grams to 1,200 of water in decoction is proper and useful in treating dysmenorrhoea.

For a long time the seeds went to waste but industry has learned to obtain from them a brownish-red oil which is used as a substitute for olive oil, from which it is hard to distinguish it, if the latter is adulterated by mixing the two; for both have the same density and a very similar odor and taste. For this reason the production of cottonseed oil is very considerable nowadays. It is cheap and excellent for domestic, industrial and pharmaceutic use.

The seeds are used in North America in dysentery and as a galactagogue, and the juice of the leaves as an emollient in diarrhoea and mild dysentery. The pulp of the seeds, after the oil is extracted, yields a sweet material called gossypose, which is dextrogyrous and has the formula C18H32O16 + 5H2O.

The cotton itself, the part used in commerce as a textile, is also the portion of the plant most widely employed in therapeutics; not only the fiber from this species is used, but also that of others that grow in the Philippines, the G. Barbadense, L. (nom. vulg. Pernambuko, Tag.), and the G. arboreum, L. (Bulak na bundok, Bulak na totoo, Tag.).

Cotton is used extensively in bacteriological laboratories as a filter of liquids and gases. This property possessed by cotton, of retaining in its fibers the germs of the air was utilized by the famous French surgeon Guérin in the treatment that bears his name. The denuded surfaces exposed to infection by airborne bacteria are completely protected against them when, according to the Guérin treatment, they are enveloped in large masses of fresh, raw cotton, presumably free from microörganisms. To avoid the possibility of infection by the cotton itself, it is now the practice to sterilize it either by means of chemicals such as carbolic acid, iodoform, etc., or by physical means such as high temperatures.

Raw cotton is used in compounding gun cotton or explosive cotton, also named pyroxylin, and this is used to make collodion, so extensively employed in medicine.

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.
