Black Horehound is distinguished by its disagreeable odour. It also belongs to the Labiatae order, among which it is distinguished by the strongly ten-ribbed salver-shaped calyx. The Ballota are natives of the temperate regions of the Eastern Hemisphere, and are remarkable for their strong offensive odour, on account of which they are for the most part rejected by cattle; hence the name from the Greek ballo (to reject). This plant (Ballota nigra) is sometimes given the opprobrious name of ‘Black Stinking Horehound.’ It is a common wayside perennial, has stout-branched stems, eggshaped wrinkled leaves, and whorls of numerous dull purple flowers.
The whole plant is as offensive in odour as it is unattractive in appearance. It is mostly found growing near towns and villages, and has accompanied our colonists to many remote countries.
It has a perennial root of a woody and fibrous nature. The leaves are arranged in pairs on the stem, each pair being at right angles to the pair it succeeds. They are stalked, with margins coarsely serrate, dull green in colour, their surfaces clothed with soft grey hairs, and with rather conspicuous veining.
The flowers are arranged in more or less dense whorls at the axils of the leaves; their colour occasionally varies to white.
The corolla of the Horehound has its upper lip erect and slightly concave, and the lower lip cleft into three, the lateral lobes being considerably smaller than the central ones. The calyx is tubular, its mouth having five short spreading teeth terminating in a stiff bristly point. The body of the calyx is sharply ridged and furrowed.
It is found in flower from June to October. The name ballote was given to this plant as early as the time of Dioscorides.
It has been suggested that the name Horehound came from two Anglo-Saxon words signifying the hoary honey-yielding plant; but other authorities find other derivations.
Dioscorides (like Gerard) declared that the Ballota was an antidote for the bite of a mad dog.
Beaumont and Fletcher’s Faithful Shepherdess has a reference to this property of the plant:
‘This is the clote bearing a yellow flower,
And this black horehound: both are very good
For sheep or shepherd bitten by a wood-Dog’s venom’d tooth.’
Cultivation details
Prefers a well-drained soil in full sun or partial shade. Avoids acid soils in the wild but tolerates a pH down to 5 in cultivation. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c. This species is widely grown in herb gardens, but little employed because of its strong flavour. Its essential oil is used to adulterate the oil of white horehound (Marrubium vulgare). The leaves emit a most unpleasant smell when bruised, somewhat like stale perspiration. Plants can self-sow freely when well-sited[238]. There is at least one named variety selected for its ornamental value. The whole plant has an offensive odour.
Propagation
Seed – sow spring or autumn in a greenhouse. The seed usually germinates in 3 – 6 weeks at 15°c[134]. Prick out the seedlings into individual pots when they are large enough to handle and plant them out into their permanent positions in the summer or following autumn. Division in spring. Larger divisions can be planted straight into their permanent positions whilst smaller clumps are best potted up and kept in a cold frame until they are growing away well.
Medicinal Action and Uses:
Antiemetic; Antispasmodic; Stimulant; Vermifuge.
Black horehound has a long history of herbal use, though is not widely employed in modern herbalism because of its unpleasant flavour. Nonetheless, it does have a range of medicinal virtues, being especially effective in its action as an antiemetic. In the past it was often used for treating problems connected with the respiratory system, convulsions, low spirits and the menopause, but present-day authorities differ over whether it was effective in these applications. The whole plant is antiemetic, antispasmodic, expectorant, stimulant and vermifuge. It is taken internally in the treatment of nervous dyspepsia, travelling sickness, morning sickness in pregnancy, arthritis, gout, menstrual disorders and bronchial complaints. The plant is harvested as it comes into flower and is dried for later use. It should not be stored for longer than a year. The fresh herb is sometimes used to make a syrup
