What Are "Star" Ratings?
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.

Black horehound has been used traditionally for heavy periods.
Reference Cinnamon has been used historically for the treatment of various menstrual disorders, including heavy menstruation.2 This is also the case with shepherd’s purse (Capsella bursa-pastoris). 3 Other herbs known as astringents (tannin-containing plants that tend to decrease discharges), such as Reference cranesbill, Reference periwinkle, Reference witch hazel, and Reference oak, were traditionally used for heavy menstruation. Human trials are lacking, so the usefulness of these herbs is unknown. Reference Black horehound was sometimes used traditionally for heavy periods, though this approach has not been investigated by modern research.

Black horehound is sometimes used by herbalists to treat nausea associated with motion sickness.
Reference Black horehound (Ballotta nigra, Marrubium nigrum) is sometimes used by herbalists to treat nausea associated with motion sickness.4 However, there are no clinical trials to confirm its effectiveness for treating this condition.

Black horehound has primarily been used in European traditional herbalism to relieve nausea, Reference anxiety, or the combination of these conditions.1 It was also used as a mild expectorant and to help normalize menstruation.
How It Works
How It Works
Phenylpropanoids—flavonoids and compounds found in the volatile oil of black horehound—are believed to be the plant’s major active constituents.5 , 6 A recent test tube study found black horehound phenylpropanoids to have both Reference antioxidant properties and a sedating effect on overactive nerve cells.7 Although no human studies have been conducted with black horehound, the herb is believed to be useful for treating nausea associated Reference motion sickness due to a possible effect on the central nervous system.8
How to Use It
Black horehound is traditionally used as a tea or tincture. Approximately 2 teaspoons of the leaves are added to 1 cup hot water and allowed to steep for 10 to 15 minutes.9 One cup is drunk three times per day. If a tincture is preferred, 1 to 2 ml may be taken three times per day. Black horehound is rarely used alone, and is frequently combined with Reference meadowsweet, Reference chamomile, or Reference ginger for relief of nausea.
Interactions with Supplements, Foods, & Other Compounds
Interactions with Medicines
There are no reports of adverse effects from use of black horehound when taken in the recommended amounts. Black horehound was traditionally used to treat Reference nausea during pregnancy, though no scientific evaluation of the safety or efficacy of this practice has been conducted. Some sources report that black horehound could induce miscarriage when taken in large amounts.10 Consult with a doctor who is trained in botanical medicine before using horehound during pregnancy.
