    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.

    1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

    This supplement has been used in connection with the following health conditions:

    Chamomile is a carminative with long history of use as a calming herb and may be used to ease intestinal cramping in colicky infants. A soothing tea made from chamomile, vervain , licorice , fennel , and lemon balm has been shown to relieve colic more effectively than placebo.4 In this study, approximately 1/2 cup (150 ml) of tea was given during each colic episode up to a maximum of three times per day.

    1 Star
    Indigestion, Heartburn, and Low Stomach Acidity
    Refer to label instructions
    Vervain is a digestive stimulant widely used in traditional medicine in North America.

    Bitter herbs are thought to stimulate digestive function by increasing saliva production and promoting both stomach acid and digestive enzyme production.5 As a result, they are particularly used when there is low stomach acid but not in heartburn (where too much stomach acid could initially exacerbate the situation). These herbs literally taste bitter. Some examples of bitter herbs include greater celandine , wormwood , gentian, dandelion , blessed thistle , yarrow , devil?s claw , bitter orange, bitter melon , juniper , andrographis , prickly ash , and centaury .6. Bitters are generally taken either by mixing 1?3 ml tincture into water and sipping slowly 10?30 minutes before eating, or by making tea, which is also sipped slowly before eating.

    Some bitters widely used in traditional medicine in North America include yarrow , yellow dock , goldenseal , Oregon grape , and vervain . Oregon grape?s European cousin barberry has also traditionally been used as a bitter. Animal studies indicate that yarrow, barberry, and Oregon grape, in addition to stimulating digestion like other bitters, may relieve spasms in the intestinal tract.7

    1 Star
    Sinusitis (Elder Flower, Gentian Root, Primrose Flowers, Sorrel)
    Refer to label instructions
    An herbal combination of gentian root, primrose flowers, sorrel herb, elder flowers, and European vervain has been found to help promote mucus drainage from the sinuses.

    One of the most popular supportive treatments for both acute and chronic sinusitis in Germany is an herbal combination containing gentian root, primrose flowers, sorrel herb, elder flowers, and European vervain .8 The combination has been found to be useful in helping to promote mucus drainage (?mucolytic? action) from the sinuses.9 The combination is typically used together with antibiotics for treating acute sinusitis.

    Traditional Use (May Not Be Supported by Scientific Studies)

    Due to its bitter taste, herbalists used vervain to improve digestion. Vervain was also used to treat people with depression and spastic pains in the gastrointestinal tract, as a mild diaphoretic (to induce sweating and promote mild fevers), and for all manner of female reproductive system problems when associated with melancholy or anxiety.1 Early 20th century Eclectic physicians (doctors who recommended herbal medicines) in the United States felt vervain might be helpful for mild digestive problems .2 Vervain also has a reputation as a traditional remedy for stimulating production of breast milk.3

    How It Works

    Common names:
    European Vervain
    Botanical names:
    Verbena officinalis

    How It Works

    The active constituents of vervain have not been thoroughly demonstrated. Glycosides, such as verbenalin and aucubin, and a volatile oil may all contribute to its activity.10 No human studies have documented the use of this herb for any condition.

    How to Use It

    A tea of vervain leaves and flowers is prepared by adding 1?2 teaspoons (2?4 grams) to a pint (500 ml) of hot water which is left to steep, covered, for 10?15 minutes.11 Three cups (750 ml) per day are typically recommended by doctors. The taste of the tea is fairly disagreeable, therefore, most people prefer a tincture. Tincture, 1?2 teaspoons (5?10 ml) three times per day, is also suggested.12
