Synonyms : Thlaspi bursa-pastoris. Bursa abscissa. Bursa druceana. Capsella concava.
Common Name ; Shepherd’s-purse
Habitat: is native to eastern Europe and Asia minor but is naturalized and considered a common weed in many parts of the world, especially in colder climates,including Britain, where it is regarded as an archaeophyte, North America and China but also in the Mediterranean and North Africa. It grows in Arable land, gardens, waste places etc, it is a common weed of cultivated soil.
Shepherd’s-purse is a small (up to 0.5m) annual and ruderal species, and a member of the Brassicaceae or mustard family. Capsella bursa-pastoris is closely related to the model organism Arabidopsis thaliana and is also used as a model organism due to the variety of genes expressed throughout its life cycle that can be compared to genes that are well studied in A. thaliana. Unlike most flowering plants, it flowers almost all year round. Like many other annual ruderals exploiting disturbed ground, C. bursa-pastoris reproduces entirely from seed, has a long soil seed bank, and short generation time and is capable of producing several generations each year.
CLICK & SEE THE PICRURES
Shepherd’s-purse plants grow from a rosette of lobed leaves at the base. From the base emerges a stem about 0.2 to 0.5 meters tall, which bears a few pointed leaves which partly grasp the stem. The flowers are white and small, in loose racemes, and produce seed pods which are heart-shaped.
Like a number of other plants in several plant families, its seeds contain a substance known as mucilage, a condition known as myxospermy. The adaptive value of myxospermy is unknown, although the fact that mucilage becomes sticky when wet has led some to propose that C. bursa-pastoris traps insects which then provide nutrients to the seedling, which would make it protocarnivorous.
Edible Uses :
Edible Parts: Leaves; Oil; Seed.
Edible Uses: Condiment; Oil.
Leaves – raw or cooked. The young leaves, used before the plant comes into flower, make a fine addition to salads. The leaves are a cress and cabbage substitute, becoming peppery with age. Leaves are usually available all year round, though they can also be dried for later use. The leaves contain about 2.9% protein, 0.2% fat, 3.4% carbohydrate, 1% ash. They are rich in iron, calcium and vitamin C. A zero moisture basis analysis is available. The young flowering shoots can be eaten raw or cooked. They are rather thin and fiddly but the taste is quite acceptable. They can be available at most times of the year. Seed – raw or cooked. It can be ground into a meal and used in soups etc. It is very fiddly to harvest and utilize, the seed is very small. The seed contains 35% of a fatty oil. This oil can be extracted and is edible. The seedpods can be used as a peppery seasoning for soups and stews. The fresh or dried root is a ginger substitute
Constituents: choline, acetylcholine and tyramine, saponins, mustard oil, flavonoids
Fumaric acid is one active substance that has been isolated.. Although Fumaric acid and its derivatives are used with success in many conditions there is no direct evidence that plant extract has been used with similar success.

Shepherd’s purse is one of the important herbs to stop bleeding an effect due to the tyramine and other amines it contains. This property leads to its use is a number of condidtions such as heavy menstrual bleeding, nosebleeds, and as a post-partum herb. The herb is both a vasodilator, and also hastens coagulation and constrict blood vessels.

Other chemicals in the herb may accelerate clotting. Still other compounds in the herb help the uterus contact, explaining the long-time use of the herb to help the womb return to normal size after childbirth. Mountain Rose Herbs (2008-07-09)
Herbally, it is primarily used to stop vaginal bleeding, an action which may be attributable to the common parasitic fungus found with it, which is related to the vasoconstrictor ergot.
