Vervain herbs are used for centuries as medicines, and they have been known to treat everything from headaches to stomach aches. They were once thought to be nothing but myths, until the 19th century when a German chemist named Carl von Linné first isolated them. Since then, researchers have confirmed their medicinal properties and even synthesized some of the active ingredients. Blue Vervain (Veratrum album)

Blue vervain is one of the most popular varieties of vervain. It’s commonly used in herbal medicine because it has many beneficial effects. Its main use is to reduce inflammation and improve circulation, which helps with pain relief and fever reduction. It also acts as a diuretic, so it can help relieve constipation. Other uses include treating wounds and skin conditions such as eczema and psoriasis.

Blue vervain may also help prevent cancer cells from spreading through your body. Blue vervain is often sold in bottles labeled “blue” or “vermilion.” Because of its high concentration of anthocyanins, blue vervain is sometimes called purple violet. It’s important not to confuse it with poison hemlock (Conium maculatum), which has a similar appearance. Vervain Herbal Information: Learn How To Grow Vervain Herb Plants

Vervain (Verbena officinalis) is a hardy flowering plant in the VERBENACEAE family, native to North and South America but cultivated elsewhere around the world, and naturalized in Britain. With its spikes of purple or pink flowers and its spreading habit, Vervain is often grown as a garden plant. The common name may also be written as “Vervain Verbena” or “True Vervain”. The names “herb Gerard” and “agrimony” are also used, but these better identify herbs from other plants in the Verbenaceae family. The species name of “officinalis” refers to its early use as a medicinal herb.

Qualities of Vervain

Vervain contains the essential oil protoverbenol, and is rich in alkaloids, flavonoids and tannins. The plant is an emmenagogue, diuretic, astringent, sedative, anti-rheumatic, anti-spasmodic, nervine and hypotensive. The herb is used for amenorrhoea, menorrhagia and leucorrhoea. Vervain can be used in the treatment of arthritis, rheumatism and nervous complaints such as insomnia and hysteria. It has been used in the treatment of neuralgia, including that occurring as a result of pregnancy.

It is also used to treat fluid retention (oedema), premenstrual tension and irregular periods. Other traditional uses include treating menopausal problems and for promoting the onset of labour.

A tincture is used in herbal medicine today, taken internally or used as a wash or poultice. When taken internally it should be used with caution because the active ingredients can have a toxic effect if too much is taken. The herb is harvested when in flower and dried for later use.

Preparation and Dosage

Vervain may be taken orally in the form of a tincture, soaked in alcohol or vegetable glycerine and stored in brown glass bottles. The dosage is from 30 to 60 drop, up to three times a day. Tincture should be taken in diluted form (1:4 with water), never straight. Tinctures are best taken diluted in a little water just before eating. The dried herb may be smoked or made into an infusion or tea for the treatment of nervous complaints and as a sedative.

The dry or fresh herb can be infused with boiling water and drunk.

Some people use Vervain extensively to treat nervousness in the form of anxiety, excitability, poor memory and low energy. It is also taken to improve focus and concentration. Many herbalists also recommend combining Vervain with other herbs such as Oats and Damiana for these purposes. As with other herbs, Vervain should not be used on a daily basis for long periods of time. If taken over a period of weeks or months it is best to take a month off every few months.
