| | | | Horehound | | | Historical writings indicate that the wild perennial plant, horehound, has
been used for centuries for medicinal purposes. Growing wild in many parts
of Europe and Asia, horehound has long been noted for its efficacy in lung
troubles and respiratory complaints.
The main active expectorant
principle in white horehound is reported to be marrubiin, which is stated
to stimulate secretions of the bronchial mucosa. Horehound has also been
used for stomach and gastrointestinal complaints due to the fact that
marrubiin stimulated bile secretions in laboratory rats.
Human
trials are warranted give the limited animal and in vitro studies
to date, as well as the extensive historical documentation linking
horehound with conditions of the respiratory tract.

Browse Sections | View Horehound products | | | Description | | | Horehound is a perennial plant with small white flowers found growing in
the wild throughout Europe and Asia. All parts of the plant are used
medicinally.1
The plant is bushy, producing numerous annual,
quadrangular and branching stems, a foot or more in height, on which the
whitish flowers are borne in crowded, axillary, woolly whorls. The leaves
are much wrinkled, opposite, petiolate, about 1 inch long, covered with
white, felted hairs, which give them a woolly appearance. They have a
curious, musky smell, which is diminished by drying and lost on keeping.
Horehound flowers from June to September.

Claudius Galen (ca. 130-200 CE), who recommended it as a therapy for
coughs and other respiratory ailments. Like Galen, Nicholas Culpeper, the
17th-century English pharmacist, commented that it was helpful for a cough
and was also useful in helping remove stubborn phlegm from the
lung.
Similarly, American Eclectic physicians (doctors who
recommended herbs) of the 19th century remarked on its value as a
medicinal plant not only for coughs and asthma but also in menstrual
complaints.2
Ancient Greeks reportedly relied on horehound
(Marrabium vulgare) to treat mad-dog bite, which explains the "hound" in
this plant's name. But over time, it has been this herb's power to control
a cough that has made it so popular. Soothing teas, lozenges, and syrups
concocted from its wooly leaves and white flowering tops make a cough more
productive by stimulating phlegm (mucus) output in the airways. Colds,
bronchitis, and other minor respiratory problems often respond to
horehound treatment as well.
The Romans esteemed Horehound for its
medicinal properties, and its Latin name of Marrubium is said to be
derived from Maria urbs, an ancient town of Italy. Other authors derive
its name from the Hebrew marrob (a bitter juice), and state that it was
one of the bitter herbs which the Jews were ordered to take for the Feast
of Passover.
The Egyptian Priests called this plant the 'Seed of
Horus,' or the 'Bull's Blood,' and the 'Eye of the Star.' It was a
principal ingredient in Caesar's antidote for vegetable
poisons.
Herbalist John Gerard (1545-1612) recommends it, in
addition to its uses in coughs and colds, to "those that have drunk
poyson or have been bitten of serpents," and it was also administered
for "mad dogge's biting." It was also once regarded as an
anti-magical herb.
According to the ancient botanist Lucius
Columella (1st Century CE), Horehound is a serviceable remedy against
Cankerworm in trees, and it is stated that if it be put into new milk and
set in a place pestered with flies, it will speedily kill them
all.
Preparations of Horehound are still largely used as
expectorants and tonics. It may, indeed, be considered one of the most
popular pectoral remedies, being given with benefit for chronic cough,
asthma, and some cases of consumption.

Browse Sections | View Horehound products | | | Constituents / Nutrients | | | Horehound contains a number of constituents, including alkaloids,
flavonoids, diterpenes (e.g., marrubiin), and trace amount of volatile
oils.3 The major active constituent in horehound is marrubiin, which is
thought to be responsible for the expectorant (promotion of coughing up of
mucus) action of the herb. In addition, marrubiin contributes to the
bitter taste of horehound, an action that increases the flow of saliva and
gastric juice, thereby stimulating the appetite.4 These actions likely
explain the long-standing use of horehound as a cough suppressant and
expectorant as well as a bitter digestive
tonic.
Alkaloids: Pyrrolidine-type. Betonicine 0.3%,
the cis-isomer turicine.
Flavonoids: Apigenin,
luteolin, quercetin, and their
glycosides.(5)
Terpenoids: Diterpenes including
marrubiin 0.3-1.0%, a lactone, as the main component with lesser amounts
of various alcohols (e.g. marrubenol, marrubiol, peregrinol and vulgarol).
Marrubiin has also been stated to be an artefact formed from a precursor,
premarrubiin, during extraction.(6)
Volatile Oils:
Trace. Bisabolol, camphene, p-cymene, limonene, Beta-pinene, sabinene and
others,(6) a sesquiterpene (unspecified).
Other
Constituents: Choline, saponin (unspecified), á-sitosterol (a
phytosterol), waxes (C26-C34 alkanes).
Browse Sections | View Horehound products | | | Pharmacological Summary | | | The chemistry of white horehound is well documented. Limited
pharmacological information is available, although expectorant properties
have been reported which support some of the herbal uses in conditions of
the upper respiratory tract. Furthermore, horehound's ability to stimulate
bile secretions suggests a benefit for digestive complaints. In view of
the lack of toxicity data and suggested cardioactive properties, white
horehound should not be taken in excessive doses.

Aqueous extracts have
been reported to exhibit an antagonistic effect towards hydroxytryptamine
in vivo in mice, and in vitro in guinea-pig ileum and rat uterus
tissue.(8) Expectorant and vasodilative properties have been documented
for the volatile oil.(9) However, the main active expectorant principle in
white horehound is reported to be marrubiin, which is stated to stimulate
secretions of the bronchial mucosa. Marrubiin has also been stated to be
cardioactive, possessing anti-arrhythmic properties, although higher doses
are reported to cause arrhythmias. Marrubin acid (obtained from the
saponification of marrubiin) has been documented to stimulate bile
secretion in rats, whereas marrubiin was found to be inactive.(10) White
horehound is stated to possess bitter properties (BI 65 000 compared to
gentian BI 10 000-30 000) with marrubiin as the main active component.
Large doses of white horehound are purgative. The volatile oil has
antischistosomal activity.(11)

documented in animals.
Horehound has been safely used for
centuries. But avoid taking more that commonly recommended. One of the
herb active ingredients, a volatile oil called marrubiin, could
potentially cause heart irregularities in large doses.
Limited
research in animals indicates that substances in horehound stimulate the
uterus. To be safe, pregnant women should avoid the
herb.
Pregnancy and Lactation
White horehound
is reputed to be an abortifacient and to affect the menstrual cycle.
Uterine stimulant activity in animals has been documented. In view of this
and the lack of safety data, the use of white horehound during pregnancy
should be avoided. Excessive use during lactation should be avoided.
Browse Sections | View Horehound products | | | Interaction with Medications | | | Horehound may dangerously increase the blood sugar-lowering effects of
drugs designed to lower blood glucose, such as insulin and oral
antidiabetic agents. Avoid combining horehound with these
medicines.
There are no other known drug or nutrient interactions
associated with horehound.
Browse Sections | View Horehound products | | | Possible Side Effects | | | Since horehound acts as a bitter and may increase production of stomach
acid, people with gastritis or peptic ulcer disease should use it
cautiously. Horehound should not be used during pregnancy, as it may
stimulate contractions.
The plant juice of white horehound is
stated to contain an irritant principle, which can cause contact
dermatitis. No documented toxicity studies were located for the whole
plant, although an LD50 (rat, by mouth) value for marrubin acid is
reported as 370 mg/kg body weight.(10) The volatile oil is documented to
be highly toxic to the flukes Schisto soma mansoni and Schistosoma
haematobium.(11)
Browse Sections | View Horehound products | | | Dosage | | | For adults, the German Commission E monograph recommends approximately 3/4
teaspoon (4.5 grams) of horehound per day or 2-6 tablespoons (30-90 mL) of
the pressed juice.5 Alternatively, horehound tea can be prepared from
approximately 1/4-1/2 teaspoon (1-2 grams) of root boiled in about 7
ounces (200 mL) of water for ten minutes. Three cups (750 mL) of this tea
can be drunk per day. Horehound is sometimes found in herbal lozenges that
are used for coughs.
Dried Extract: Horehound capsules are
generally available in strengths that range from 400 to 700 mg. Within
herbal blends, quantities of horehound are significantly smaller.
Typically, a capsule strength of 400 to 500 mg is recommended to be taken
3 times daily.
