In almost every European language the name of the plant is associated with the shape of the fruit of the plant.
It is either gathered from the wild or cultivated.
Originally native to Eastern Europe and Asia Minor, it has been naturalized in the UK and other colder climates. In the UK it blossoms all year around.
In Greenland it can be found in places where it was first introduced by Norse settlers 1000 years ago.
In Africa it does grow but only in higher altitudes.
- Fumaric acid is contained in the plant
A notable feature of C. bursa-pastoris is that it contains acetylcholine. Acetylcholine is a neurotransmitter, responsible for the parasympathetic neurotransmission in our organism. This is probably the substance that provides the herb with its diuretic properties by interacting with the muscarinic receptors.
Bursic acid is another phytochemical of the plant, which is responsible for stopping bleeding.
Cardioactive steroids are presumably present only in the seeds.
TCM Formulas in which it is included:
The plant’s usage in western herbal medicine is based on it’s astringency. It is documented in the UK as a remedy for for excessive menstrual bleeding  Based on this traditional use even today there are commercially available food supplements.
In Limerick (Ireland) it has been used for the treatment of kidney problems.

It has been shown that a mixture of extracts of C. bursa-pastoris and Glychyrrhiza glabra is effective against oral micro-organisms so it can potentially be used for oral hygiene. 
The seeds are often used in bird seed mixes. 
It is consumed as food in several countries of the Mediterranean like Spain, Morocco, Turkey and Bosnia Herzegovina. It is also used in the traditional Korean dish namul.
It contains a high amount of calcium but low amounts of oxalic acid making it a relatively good source for this element. 
Seeds and young shoots are eaten raw. Tender Rosettes of young leaves are collected in spring and eaten raw. 
Although as stated earlier it has a low oxalic acid/calcium ratio (<1) it still contains oxalic acid so its consumption is not advised for people with kidney stones or even endometriosis.
