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. 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.. 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.
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. The combination has been found to be useful in helping to promote mucus drainage ("mucolytic" action) from the sinuses. 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

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.4 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.5 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.6
