(From the Arabic term erbah, from raba/i, to germinate). Herbs, or plants whose stalks die to the ground every year.' Those whose roots continue one year are called annual; if two years, biennial; and if durable, perennial. In common language, an herb is used in opposition to a tree. By Linnaeus the herb is put for that part of a vegetable which arises from the root, is terminated by the fructification, and comprehends the stem, leaves, fulcra, and hybernacula.
Herbs are to be gathered when the leaves are at their full growth, before the flowers unfold, except those whose flowery tops are preferred.. They should be quickly dried, in a room heated by a fire to a degree equal to the hottest day, from 75° to 80c. Aromatic plants should be collected from warm dry soils; fetid ones from those which are moist and rich. All herbs and leaves should be gathered in clear dry days, as soon as the morning dew is dissipated. When herbs are properly dried, they are good while their colour remains, both for decoctions and distillation; those that are good when dry are preferable to the same herbs in their green state.
