Marrubium vulgare L.

White horehound

English name: White horehound

Family: Lamiaceae 

Botanical characteristic: A perennial herb reaching a height of 50 cm. The stem is woody at the base, four-angled, and white-woolly. Opposite, grayish-green leaves are egg-shaped, wrinkled, and serrated. White flowers emerge in the leaf axils in whorls. The fruit is a dry multi-seeded divisible fruit (lat. Carcerulus).

Microscopic drawing:

The skin of a white horehound leaf is densely covered with covering (a), candelabra (b) and glandular (c) trichomes. We can also find disc-shaped glands (d) and stomata with two accompanying cells (e), which is characteristic for the microscopy of representatives of the sedum plant.

Distribution: Originally originating from Southern Europe, it occurs from lowlands to high mountain areas. It is often found along roadsides and fences.

Drug: Marrubii herba

Harvesting method: The stalk is harvested during the flowering period from June to September using gardening scissors. 

Drying: Drying common hawthorn is done naturally in thin layers in a dark room. Alternatively, artificial drying can be carried out at temperatures up to 35°C.

Active substances: The hot taste of the entire plant is attributed to bitter-tasting compounds, primarily marubin, with a dominance of bitterness. The remainder consists of tannins, organic acids, especially chlorogenic and caffeic acids. Flavonoids and essential oils make up the remaining substances.

Uses: With its bitterness, white horehound promotes the secretion of digestive juices, stimulates digestion and increases appetite.

Traditional method of use in indications determined solely on the basis of long-term use:

– expectorant in a productive cough related to a cold,

– symptomatic treatment of mild dyspeptic complaints, bloating and flatulence,

– supportive treatment for temporary loss of appetite.
