The herbaceous plant known as the avens is characterized by possessing thin and almost upright wiry stems; this herb is slightly branched and can reach one to two feet when fully grown. The herb is reddish brown in color on one side of the body.
The avens has leaves that vary to a very significant extent in physical form; this physical appearance of the leaves depends to some extent on their position along the axis of the plant. The avens bears radical leaves that are borne on long and channeled foot stalks; the leaves are interruptedly pinnate in their shape similar to the silverweed plant.
The large and terminal leaflet is shaped like a wedge while, the pairs of leaflets in the middle are quite small in size. Leaves on the upper part of the stem consists of three long and narrow leaflets, while the leaves lower along the stems are made of three leaflets which are round and full in shape.
Leaves on the stem are borne on alternate sides and possess two stipules at the base - these "stipules" are structures that occur at the junction of the base of the leaf, in the area touching the stem in many plants. The stipules of the avens are very large, each is about an inch broad and is very long and rounded in physical form, and it is also mostly coarsely toothed and comes out in lobes.
The avens bears leaves that are of a deep green color, most of the leaf surface is covered with hairs spread out all over, thee margins of the leaves are also toothed or serrated.
The avens also has rhizomes, each single rhizome is about one to two inches in length and terminates quite abruptly, and most of these structures are hard and rough and bear many light brown and fibrous roots all along the surface.
The avens also bears flowers that are considered small compared to the total size of the plant, the flowers are borne on solitary and terminating stalks along the main axis of the plant.
The flowers of the avens have a corolla that consists of five round and spreading yellow colored petals, while the calyx of the flower is split into ten different segments, five of these segments are large while the other five are small - this arrangement on the flower is comparable to the floral arrangement seen in the silverweed.
The flowers of the avens are less showy than the round fruit heads, even though the floral bloom lasts all summer and autumn, even as long as December. The rounded fruit heads that succeed the floral bloom are much more visible, these are composed of a mass of dark crimson colored achenes, with each single achene terminating in an awn, the terminal part of which is curved into a hook like structure.
The name of the avens is a derivative from the Latin - Avencia - a name sourced from the Medieval Latin "avantia or avence", this is already a word now seen as obscure with unclear origins. However, it is a name that has been given to this plant in a variety of spellings since early history.
The avens has a botanical name - Geum - that comes from the Greek word geno, a word that means to "yield an agreeable fragrance"; one reason for this name is that when the root is dug up fresh, it has an aroma that is similar to the smell of cloves.
As a consequence, another name, Radix caryophylata or clove root, and a further corruption of the name - Gariophilata, is often given to this herb as well. Many other common names including Minarta, Assarabaccara, Pesleporis or Harefoot were given to the avens in the fourteenth century.
The avens was also commonly known as 'the Blessed Herb' - Herba benedicta, this common name is still in use today in the form of a verbal corruption - Herb Bennet. One reason for the name was that in the past, the herb was believed to have the power to ward off all sorts of evil spirits and venomous beasts of all kinds. As a result, the herb was commonly worn on an amulet by people who wanted protection from evil spirits and dangerous beasts.
During the medieval age, the very graceful appearance of the trefoiled leaf of the plant and the five gold colored petals seen in the blossoms was seen as symbols of the Holy Trinity, these were even though to represent the five wounds of Jesus.

The dried roots would then be sliced up and grounded into powder as required in the medication - this drying and grounding of the roots makes them much less likely to lose their beneficial properties, then merely slicing them up for dry storage.
When dried, the external appearance of the rhizome is almost brown in color and is sometimes a brownish yellow color as well. The fracture within the rhizome is short. The inside of the dried rhizome is light purplish to brown in color.
The transverse section of the rhizome shows large pith, with a narrow woody ring all around, along with a very thin bark on the rim. Avens based medication is slightly bitter in taste, it is even described as tasting like cloves - the avens has great effect as a potent astringent.
