Should not be used more than 2 days at a time.

"...where the root is in the house, Satan can do nothing and flies from it, wherefore it is blessed before all other herbs,
and if a man carries the root about him, no venemous beast can harm him."
(Maude Grieve, quoting from Ortus Sanitatis written ca 1491).

CONTAINS: The principle constituent of the root is a volatile oil which is composed mainly of eugenol and a glucoside, plus Gein, geum-bitter, tannic acid, gum and resin.
Distilled with water, it yields 0.04% of thick, greenish, volatile oil.
Tannins equal 1/11th of its weight.

A common wayside perennial in Great Britain which has been used medicinally since Roman times and is closely related to Potentilla. It is abundant in woods and hedges in England, Ireland and southern Scotland. It is common in the greater part of Europe, Russia and Central Asia. The thin wiry stems are slightly branched and are 1 to 2 feet in height with a reddish-brown coloration on one side. The leaves vary considerably according to their position on the plant but the upper leaves are composed of 3 narrow leaflets. The rhizomes are 1 to 2 inches long and terminate abruptly; they are hard and rough with many light brown fibrous roots. Flowers are small (about ¾ inch across), golden-yellow, without scent and on solitary terminal stalks. The corolla is made up of 5 roundish, spreading yellow petals and a calyx which is split into 10 segments - 5 large and 5 small. Flowers are inconspicuous and bloom all summer into autumn. The pointed sepals are visible between each pair of petals. The fruits are contained in small brown burred tassels. A good choice for the front of the border.

The plant derives its common name from the Latin "avencia" (meaning is unclear). The botanical name Geum is from the Greek "geno" meaning to yield an agreeable fragrance. When freshly dug, the root has a clove-like aroma. It was called "the Blessed Herb" in earlier times and the common name "Herb Bennet" is a possible corruption of that. It was believed to have the power to ward off evil spirits and venomous beasts and was worn as an amulet. In Dr. Prior's Popular Names of English Plants the author considers the original name to have probably been "St. Benedict's Herb" since that name was assigned to herbs that were supposed to be antidotes of those things alluding to the saint. Hemlock is also known as Herb Bennett which may allude to a story involving St. Benedict and an attempt to poison him. In mediaeval days the trefoiled leaf and the five golden petals of the blossoms symbolized the Holy Trinity and the 5 wounds of Jesus.
Towards the end of the 13th century the plant frequently occurs as an architectural decoration in the carved leafage on the capitals of columns and in wall patterns.
Astrologically it is ruled by Jupiter. It was well known to the gypsies who called it "the kind herb".
In the past it has been known to have been adulterated with Arnica.

PROPAGATION: By seed sown in autumn or spring (self-seeds freely); it is more easily propagated by root division in spring or fall.
NEEDS: Rich, moist soil in part shade to full shade; grows best in soil which does not dry up in summer. Happy in semi-shade of other plants and ordinary soil. Plant 12 inches apart at the front of the border.
FLOWERS: June to August
HARVEST: Plants are cut as they begin flowering and are dried for infusions and liquid extracts. The roots are lifted in spring and used fresh or dried for decoctions and liquid extracts. In former times, physicians fixed the date of March 25th, to harvest the roots and that the soil must be dry. It was said that the root was the most fragrant at this time and loses much of its odor in drying, so must be dried with great care and slowly; then sliced and powdered as required. In the whole dried form it would retain its properties longer than if stored in a sliced or powdered form. When dried the rhizome is of a brownish to brownish-yellow color. Internally it is of a light purplish-brown when dried. In a crosswise cut, it shows a large pith, a narrow woody ring, and thin bark. Taste is astringent, slightly bitter and clove-like.
PART USED: Whole flowering plant and roots.
SOLVENT: Water and alcohol (which the root will tinge red).

This has been used like Water Avens (G. rivale) and considered tonic, powerful astringent, styptic, febrifuge and stomachic.



White Avens
(Geum canadense)
imageImage

Taller than Yellow Avens and can grow to 3½ feet. The stalks of flowers are covered with small glandular hairs. Flowers are white with petals broader at the tips than the base. Native to eastern and central Canada, Minnesota, North Dakota and south to Texas, Oklahoma, Alabama and Scouth Carolina in rich thickets and borders of woods. Used by the Iroquois for fever and diarrhea. The root was used by the Chippewa for female weakness.

(Geum aleppicum var. strictum)
[wu qi chao yang cao]
imageImage

Native to North America, about a foot tall and covered with spreading brownish hairs. The leaves consist of many opposite leaflets of various shapes with tiny ones in between and always one large leaflet at the end of the stalk. Leaves are green and hairy on both sides, having long stalks, when at the base of the plant, and none when they near the top. Flowers are roughly 1 inch in size and deep yellow to orange in color with 5 petals and are solitary at the ends of the stems. These are followed by brown balls of hooked bristles.

Native Americans and early settlers used a weak decoction taken internally for soreness in the chest and for coughs. The Iroquois used this as well as G. canadense (White Avens), and G. rivale (Water Avens) for fever and diarrhea.

It is native to Labrador, Newfoundland, New Brunswick, Prince Edward Island, Nova Scotia, Quebec, Ungava Bay ONT, Manitoba to British Columbia and south to Washington, New Mexico, Missouri, Indiana, Pennsylvania and North Carolina, Iceland, Europe and Western Asia in swamps and wet places. It is found chiefly in damp woods and in ditches and among coarse herbage fringing canals, but are most often seen along rivers and streams. It is a stouter plant than G. urbanum and with a hairy stem. It has fewer flowers, although they are larger in size. This is not a wide spreading star shaped flower as with other Geums, but a drooping flower which is compact and forms a bell-shape with the corolla of a dull purplish hue with darker veins. One writer describes them as resembling wine glasses held in a green calyx. The outer petals (sepals) are purple, the inner petals are yellowish, suffused with purple and are purple veined. The flowers nod at the end of the stems. The seeds have feathery hairs sticking out from them. In the eastern United States it is called Indian Chocolate, Cure All and Water Flower. It was used by Native Americans and by early European settlers who were already familiar with the use of Geums.

NEEDS: Flourishes in a moist situation.
HARVEST: Root is dug in spring before the stem grows up.
PART USED: The root and the above ground plant.
