PATCHOULY.—Under this name are imported into this country the dried foliaceous tops of a strongly odoriferous labiate plant, growing three feet high in India and China, called in Bengalee and Hindu, pucha pat. About 46 cases, of from 50 to 110 lbs. each, were imported from China, by the way of New York, in 1844. The price asked was 6s. per pound. Very little is known of the plant yielding it. Mr. George Porter, late of the island of Pinang, stated that it grows wild there and on the opposite shores of the Malay peninsula. Dr. Wallich says, that it obviously belongs to the family Labiatæ. Viney, in the "French Journal of Pharmacy," suggests that it is the Plectranthus graveolens of R. Brown. It forms a shrub of two or three feet in height. It is the Pogostemon patchouly. The odor of the dried plant is strong and peculiar, and to some persons not agreeable. The dried tops imported into England are a foot or more in length. In India it is used as an ingredient in tobacco for smoking, and for scenting the hair of women. In Europe it is principally used for perfumery purposes, it being a favorite with the French, who import it largely from Bourbon. The Arabs use and export it more than any other nation. Their annual pilgrimship takes up an immense quantity of the leaf. They use it principally for stuffing mattrasses and pillows, and assert that it is very efficacious in preventing contagion and prolonging life. It requires no sort of preparation, being simply gathered and dried in the sun; too much drying, however, is hurtful, inasmuch as it renders the leaf liable to crumble to dust in packing and stowing on board. The characteristic smell of Chinese or Indian ink is owing to an admixture of this plant in its manufacture. M. de Hugel found the plant growing wild near Canton. By distillation it yields a volatile oil, on which the odor and remarkable properties depend. This oil is in common use in India for imparting the peculiar fragrance of the leaf to clothes among the superior classes of natives. The origin of its use is this:—A few years ago, real Indian shawls bore an extravagant price, and purchasers could always distinguish them by their odor; in fact, they were perfumed with Patchouly; the French manufacturers at length discovered this secret, and used to import the plant to perfume articles of their make, and thus palm off homespun shawls as real India! Some people put the dry leaves in a muslin bag, and thus use it as we do lavender, scenting drawers in which linen is kept; this is the best way to use it, as this odor, like musk, is most agreeable when very dilute.—("Gardeners' Chronicle.")
The root of some parasitical plant, under the name of kritz, is used in Cashmere to wash the celebrated shawls, soap is used only for white shawls.
From the flowers of the Bengal quince (Ægle marmemolos) a fragant liquid is distilled in Ceylon known as marmala water, which is much used as a perfume for sprinkling by the natives.
Jasmine oil is distilled from Jasminum sambac and grandiflora.
SAPONACEOUS PLANTS.—Many plants furnish abroad useful substitutes for common soap. The aril which surrounds the seed and the roots of Sapindus Saponaria, an evergreen tree, I have seen used as soap in South America and the West Indies under the name of soap berries. The seed vessels are very acrid, they lather freely in water and will cleanse more linen than thirty times their weight of soap, but in time they corrode or burn the linen. Humboldt says that proceeding along the river Carenicuar, in the Gulf of Cariaco, he saw the Indian women washing their linen with the fruit of this tree, there called the parapara. Some other species of Sapindus and of Gypsophila have similar properties. The bruised leaves and roots of Saponaria officinalis, a British species, form a lather which much resembles that of soap, and is similarly efficacious in removing grease spots. The bark of many species of Quillaia, as Q. saponaria, when beaten between stones, makes a lather which can be used as a substitute for soap, in washing woollens and silk clothes, and to clean colors in dyeing, in Chili and Brazil, but it turns linen yellow. The fruit of Bromelia Pinguin is equally useful. A vegetable soap was prepared some years ago in Jamaica from the leaves of the American aloe (Agave Americana) which was found as detergent as Castile soap for washing linen, and had the superior quality of mixing and forming a lather with salt water as well as fresh. Dr. Robinson, the naturalist, thus describes the process he adopted in 1767, and for which he was awarded a grant by the House of Assembly:—"The lower leaves of the Curaca or Coratoe (Agave karatu) were passed between heavy rollers to express the juice, which, after being strained through a hair cloth, was merely inspissated by the action of the sun, or a slow fire, and cast into balls or casks. The only precaution necessary was to allow no mixture of any unctuous materials, which destroyed the efficacy of the soap. A vegetable soap, which has been found excellent for washing silk, &c. may be thus obtained. To one part of the skin of the Ackee add one and a half part of the Agave karatu, macerated in one part of boiling water for twenty-four hours, and with the extract from this decoction mix four per cent. of rosin. In Brazil, soap is made from the ashes of the bassura or broom plant (Sidu lanceolata) which abounds with alkali. There are also some soap barks and pods of native plants used in China. Several other plants have been employed in different countries as a substitute for soap. The bark of Quillaia saponaria renders water frothy and is used as a detergent by wool dyers. Saponaria vaccana is common in India. The pericarp of Sapindus emarginatus mixed with water froths like soap. Saponaceous berries are found in Java.
The soap-worts to which the genus Sapindus belongs are tropical plants. The fruit of many species of Sapindus is used as a substitute for soap, as Sapindus acuminata, Laurifolius emarginatus and detergens, all East Indian plants.
