Black horehound (Ballota nigra) is a three-foot, perennial herb of the family Lamiaceae. It is native to the Mediterranean and central Asia, and can be found throughout Europe and the eastern United States. Black horehound has a very strong smell, and can be recognized by its clusters of hairy, reddish-purple flowers. The aerial parts of the plant are used medicinally, either alone or in combination with other herbs. Usually, the aerial parts are prepared as an herbal extract.
Black horehound has been used in traditional European herbalism for nervous dyspepsia (upset stomach), traveling sickness, morning sickness in pregnancy, arthritis, gout (foot inflammation), menstrual disorders, and bronchial complaints.
Black horehound has been used for nausea and vomiting, and as a mild sedative. However, its popularity has waned due to the plant's extremely foul odor. Although clinical data is lacking, laboratory studies indicate that black horehound may have some sedative, antioxidant, and antibiotic properties.

Adults (18 years and older)
There is no proven safe or effective dose for black horehound. Traditionally, black horehound has been taken as a dried herb, tea, syrup or tincture. For instance, 2-4 grams of dried herb have been taken three times a day; 3 cups of tea (prepared using 2oz. fresh horehound leaves per 2.5 cups of fresh, non-chlorinated water) have been taken daily; 1 teaspoonful of syrup has been taken three times a day, or every two hours, for acute illness; and 10-15 drops of tincture (1:10, 45% ethanol) has also been taken three times daily.
Children (younger than 18 years)
There is no proven safe or effective dose for black horehound in children.
SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Avoid in individuals with a known allergy or hypersensitivity to black horehound, its constituents, or related members of the Lamiaceae family.
Side Effects and Warnings
Adverse effects information is based on traditional health practice patterns and expert opinion; there are no available reliable human trials demonstrating safety or efficacy of black horehound. Overdose may result in death.
Black horehound is possibly unsafe when used in pregnant or breastfeeding women, children, and patients taking iron supplements or sedating agents. It is also theoretically unsafe when used in patients with Parkinson's disease, as black horehound may block the effects of dopamine in the brain.
Pregnancy and Breastfeeding
Black horehound is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
Interactions with Drugs
Although not well studied in humans, black horehound may have antibiotic (antibacterial) and antioxidant effects. Use cautiously when taking black horehound with other agents with similar effects due to possible additive effects.
Black horehound may inhibit LDL oxidation. Caution is advised when taking concomitantly with other cholesterol-lowering agents, including statins.
Black horehound may decrease the efficacy of dopamine agonists.
Black horehound may also have neurosedative effects, and may increase the amount of drowsiness caused by some drugs. Examples include benzodiazepines such as lorazepam (Ativan®) or diazepam (Valium®), barbiturates such as phenobarbital, narcotics such as codeine, some antidepressants, and alcohol. Caution is advised while driving or operating machinery.
Interactions with Herbs and Dietary Supplements
Although not well studied in humans, black horehound may have antibiotic (antibacterial) and antioxidant effects. Use cautiously when taking black horehound with other herbs or supplements with similar effects due to possible additive effects.
Black horehound may inhibit LDL oxidation. Caution is advised when taking concomitantly with other cholesterol-lowering agents, such as red yeast rice.
Black horehound may decrease the efficacy of dopamine agonists.
When black horehound is taken internally, it may interfere with the absorption of iron and other minerals.
Black horehound may also have neurosedative effects, and may increase the amount of drowsiness caused by some herbs or supplements.
