long whitish tube; the upper lip short, round, and notched atthe apex; the lower one separated into three segments, theundermost of which is inversely ovate. The filaments arecrowned with simple anthers; the style is slender and bifid;and the seeds are four, at the bottom of the calyx.

Qualities. —The leaves of hyssop have an agreeable aromaticodour, and a bitterish moderately warm taste; qualities thatappear to depend on a volatile oil of a yellow colour, whichcan be obtained separate by distillation with water. It iselevated by alcohol also; but soon exhales, and the spirit losesthe odour it had when newly distilled.

Medical properties and uses. — Hyssop is stimulant and tonic.It has been recommended in hysteria; and was formerly em-ployed in catarrhal and other pulmonary affections with theview of promoting expectoration; but the stimulant propertiesof hyssop render its use doubtful in these diseases; and as atonic it scarcely merits the least attention.INULA.
