Antidiarrhoeal;  Antidote;  Antiflatulent;  Antiseptic;  Antispasmodic;  Appetizer;  Cholagogue;  Diaphoretic;  
Digestive;  Diuretic;  Emmenagogue;  Expectorant;  Hepatic;  Stimulant;  TB;  
Tonic.

White horehound is a well-known and popular herbal medicine that is often used as a domestic remedy for coughs, colds, wheeziness etc[4, 254]. The herb apparently causes the secretion of a more fluid mucous, readily cleared by coughing[254]. The leaves and young flowering stems are antiseptic, antispasmodic, cholagogue, diaphoretic, digestive, diuretic, emmenagogue, strongly expectorant, hepatic, stimulant and tonic[4, 7, 9, 21, 165, 238]. Horehound is a very valuable pectoral, expectorant and tonic that can be safely used by children as well as adults[4]. It is often made into a syrup or candy in order to disguise its very bitter flavour, though it can also be taken as a tea[4]. As a bitter tonic, it increases the appetite and supports the function of the stomach[254]. It can also act to normalize heart rhythm[254]. The plant is harvested as it comes into flower and can be used fresh or dried[238]. The root is a remedy for the bite of rattlesnakes, it is used in equal portions with Plantago lanceolata or P. major[207]. The German Commission E Monographs, a therapeutic guide to herbal medicine, approve Marrubium vulgare for dyspepsia, loss of appetite (see [302] for critics of commission E).
Other Uses
Essential;  Repellent.

An essential oil is obtained from the plant and used as a flavouring in liqueurs[46]. The plant has been used as a cure for cankerworm in trees[238]. No more details are given but it is probably a strong infusion of the flowering shoots, or the essential oil, that is used[K]. The growing plant repels flies[201].
Cultivation details
White horehound is an easily grown plant that succeeds in most well-drained soils[200], though it flourishes best in a poor dry soil[1, 4]. Another report says that the plant flourishes best where there is plenty of nitrogen in the soil[274]. It prefers neutral to alkaline soil conditions[238] and requires a warm sunny position if it is to do well[14]. Often grown in the herb garden and sometimes cultivated commercially as a medicinal herb[4, 61]. If the plant is cut back after flowering it will normally produce a second crop of leaves[238]. The fresh leaves have a pronounced musky smell, though this is lost once the plant is dried[245]. A good bee plant[1]. White horehound is a good companion plant for growing near tomatoes[24]. The tomatoes crop for a longer period and also produce a heavier crop[201].
Propagation
Seed - sow April/May or August/September in a cold frame. Germination can be slow and erratic[200]. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in the following spring[K]. Basal cuttings in late spring. Harvest the shoots with plenty of underground stem when they are about 8 - 10cm above the ground. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer. Division in spring[1]. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
