Gums and Gum-Resins.—Among the natural vegetable substances<br />

which are collected and put upon the market, a certain class <strong>of</strong> gums<br />

and gum-resins may be included. They are the exudations from plants<br />

either from the stings <strong>of</strong> insects, or from incisions made for the purpose<br />

<strong>of</strong> collecting the gum or gum-resin. The collection <strong>of</strong> gums and their<br />

preparation for the market forms a very large and important industry.<br />

Besides the gums and gum-resins, there are many substances known<br />

commercially as gums which are <strong>of</strong> an entirely different character—as<br />

opium, which is a concreted juice, and catechu, which is properly an<br />

extract.<br />

Herbs.—In pharmacy herbs are understood to be the upper portion <strong>of</strong><br />

small plants, including the leaves, flowers and small stalks, the larger<br />

stalks and roots being discarded. Commercially, the smaller plants,<br />

which are gathered entire, are also classed with herbs. Herbs should<br />

generally be gathered when in blossom, carefully dried without artificial<br />

heat, and packed away in a cool, dry place.<br />

Plants.—Plants, as the term is understood botanically, include all<br />

vegetable-growths, great or small; but in pharmacy the name is<br />

generally applied to small plants which are gathered and used entire.<br />

They should be gathered about the season <strong>of</strong> flowering, and dried<br />

without artificial heat.<br />

Leaves.—Leaves should be gathered when the plants or trees are at<br />

their fullest prime. With plants, this is generally a little before the<br />

flowering season ; and with trees and shrubs, usually a little before the<br />

ripening <strong>of</strong> the fruit. Leaves should be dried without artificial heat and<br />

packed away in a cool, dry place.<br />

Nuts.—Nuts are properly classed with fruits. They are gathered when<br />
