I have said that they carry on a commercial intercourse with the white traders. It is not of much magnitude, and their exports consist altogether of the native and spontaneous productions of the soil, sarsaparilla being one of the chief articles. They gather this (the women and children do) during six months of the year. The other six months no industry is followed,—as this period is spent in hostile excursions against the neighboring tribes. Their imports consist of iron tools and pieces for weapons; but they more especially barter the product of their labor for ornamental gewgaws,—such as savages universally admire and desire. Their sarsaparilla is good, and much sought for in the medical market.

Every one is acquainted with the nature and character of this valuable medicinal root, the appearance of which must also be known to almost everybody,—since it is so very common for our druggists to display the bundles of it in their shop windows. Perhaps every one is not acquainted with the fact, that the sarsaparilla root is the product of a great many different species of plants most of them of the genus Simlax, but not a few belonging to plants of other genera, as those of Carex and Herreria the roots of which are also sold as sarsaparilla. The species of simlax are widely distributed throughout the whole torrid zone, in Asia, Africa, and America, and some kinds are found growing many degrees outside the tropics,—as is the case in Virginia and the valley of the Mississippi, and also on the other side of the Pacific on the great continent-island of Australia.

The best sarsaparilla, however, is that which is produced in tropical countries, and especially in moist situations, where the atmosphere is at once hot and humid. It requires these conditions to concentrate the virtue of its sap, and render it more active.

It would be idle to give a list of the different species of simlax that furnish the sarsaparilla root of the pharmacopeia. There is an almost endless number of them, and they are equally varied in respect to excellence of quality; some kinds are in reality almost worthless, and for this reason, in using it as a medicine, great care should be taken in the selection of the species. Like all other articles, either of food or medicine, the valuable kinds are the scarcest; the reason in this case being that the best sarsaparilla is found in situations not only difficult of access, but where the gathering of its root is attended with considerable danger, from the unhealthy nature of the climate and the hostility of the savages in whose territory it grows. As to the quantity that may be obtained, there is no limit, on the score of any scarcity of the plant itself, since it is found throughout all the countries of tropical America plenteously distributed both in species and individual plants. Such quantities of it grow along the banks of some South-American rivers, that the Indians have a belief that those streams known as black waters—such as the Rio Negro and others—derive their peculiar color from the roots of this plant. This, however, is an erroneous supposition, as there are many of the white-water rivers that run through regions abundantly supplied with the sarsaparilla root. The black water, therefore, must arise from some other cause, as yet unknown.

As observed, the sarsaparilla of the Mundrucu country is of the very best quality. It is the Simlax papyracea of Soiret, and is known in commerce as the “Lisbon,” or “Brazilian.” It is a climbing plant, or under-shrub, the stem of which is flattened and angular, with rows of prickles standing along the prominent edges. Its leaves are of an oval acuminated shape, and marked with longitudinal nerves. It shoots up without any support, to a height of fifteen or twenty feet, after which it embraces the surrounding branches of trees and spreads to a great distance in every direction. The main root sends out many long tendrils, all of like thickness, covered with a brownish bark, of sometimes of a dark-gray color. These tendrils are fibrous, and about as thick as a quill. They present a constant tendency to become crooked, and they are also wrinkled longitudinally, with here and there some smaller lateral fibres branching off from the sides.

It is in the bark or epidermis of the rhizomes that the medicinal virtue lies; but the tendrils—both rhizome and bark—are collected together, and no attempt is made to separate them, until they have reached their commercial destination. Indeed, even these are sold together, the mode of preparing the root being left to the choice of the consumer, or the apothecary who procures it.

The Mundrucus collect it during the six months of the rainy season, partly because during the remaining six they are otherwise employed, and partly for the reason that, in the time of rain, the roots are more easily extracted from the damp soil. The process simply consists in digging them up or dragging them out of the earth—the latter mode especially where the tendrils lie near the surface, and they will pull up without breaking. If the main root be not dug out, it will send forth new tendrils, which in a short time would yield a new crop; but the improvident savages make no prudential calculations of this kind—present convenience forming their sole consideration; and on this account both the root and plant are generally destroyed by them during the operation of collecting.

As already stated, this labor devolves upon the women, who are also assisted in it by their children. They proceed into the depths of the forest—where the simlax grows in greatest abundance—and after collecting as much root as they can carry home with them, they return with their bundles to the malocca. When fresh gathered the sarsaparilla is heavy enough—partly on account of the sap which it then contains, and partly from the quantity of the mud or earth that adheres to the corrugated surface of the roots.

It is extremely probable that in this fresh state the virtue of the sarsaparilla, as a blood-purifier, is much greater than after it has passed through the channels of commerce; and the writer of this sketch has some reason, derived from personal experience, to believe that such is the case. Certain it is, that the reputation of this invaluable drug is far less in countries where the plant does not grow, than in those where it is common and can be obtained in its fresh state. In all parts of Spanish America its virtues are unquestioned, and experience has led to a more extensive use of it there than elsewhere. It is probable, therefore, that the virtue exists in the juice rather than the cortical integument of the rhizome; and this of course would be materially altered and deteriorated, if not altogether destroyed, in the process of exsiccation, which must necessarily take place in the time required for transporting it to distant parts of the world. In the European pharmacopeia it is the epidermis of the root which is supposed to contain the sanitary principle; and this, which is of a mucilaginous nature and slightly bitter taste, is employed, both in decoctions and infusions, as a tonic and alterative. In America, however, it is generally taken for what is termed purifying the blood—for the same purpose as the rhizomes of the Laurus sassafras and other plants are used; but the sarsaparilla is generally considered the best, and it certainly is the best of all known medicines for this purpose. Why it has fallen in the estimation of the Old-World practitioners, or why it never obtained so great a reputation as it has in America, may arise from two circumstances. First, that the root offered for sale is generally the product of the less valuable species; and second, that the sap, and not the rhizome, may be the part that contains the virtuous principle.

When the collected roots have been kept for awhile they become dry and light, and for the convenience of stowage and carriage—an important consideration to the trader in his eight-ton garratea—it is necessary to have the roots done up in packages of a uniform length and thickness. These packages are formed by laying the roots side by side, and doubling in the ends of the longer ones. A bundle of the proper size for stowage contains an arroba of twenty-five pounds, though the weight varies according to the condition of the root. Uniformity in size is the chief object aimed at, and the bundles are made of a round or cylindrical shape, about five inches in diameter, and something more than a yard in length. They are trimmed off small at the ends—so as to admit of stowage without leaving any empty space between two tiers of them—and each bundle is tightly corded round from one end to the other with a “sipo,” or creeping plant.
