Coltsfoot (Tussilago farfara (мати-й-мачуха)

 

Tussilago farfara, commonly known as Coltsfoot, is a plant in the

family Asteraceae.

 

It has been used medicinally as a cough suppressant. The name

"tussilago" itself means "cough suppressant." The plant has been used

historically to treat lung ailments such as asthma as well as various

coughs by way of smoking. Crushed flowers supposedly cured skin

conditions, and the plant has been consumed as a food product.

 

Description

 

Coltsfoot is a perennial herbaceous plant that spreads by seeds and

rhizomes. Tussilago is often found in colonies of dozens of plants. The

flowers, which superficially resemble dandelions, appear in early spring

before dandelions appear. The leaves, which resemble a colt's foot in

cross section, do not appear usually until after the seeds are set.

Thus, the flowers appear on stems with no apparent leaves, and the later

appearing leaves then wither and die during the season without seeming

to set flowers. The plant is typically between 10 - 30 cm in height.

 

Distribution

 

Coltsfoot is native to several locations in Europe and Asia. It is also

a common plant in North America and South America where it has been

introduced, most likely by settlers as a medicinal item. The plant is

often found in waste and disturbed places and along roadsides and paths.

In some areas it is considered an invasive species.

 

Synonym

 

Other common names include Ass's foot, Bull's foot, Butterbur,

Coughwort, Farfara, Foal's foot, Foalswort, Horse Foot and Winter

heliotrope. Sometimes it is confused as Petasites frigidus, or Western

Coltsfoot.

 

Uses

 

Coltsfoot is used as a food plant by the larvae of some Lepidoptera

species including The Gothic and Small Angle Shades. The Coltsfoot is

also worked by the honey bee (Apis mellifera mellifera). Dried coltsfoot

is often used as a tobacco alternative, notably in Amsterdam, since the

legal status of tobacco was tightened in August 2008.

 

Coltsfoot has also become a popular confectionery product made by using

Coltsfoot essence to create a hardened rock that is used to soothe sore

throats and chesty coughs; the recipe has been developed exclusively by

Stockley's Sweets of Oswaldtwistle, UK and has become a favourite

medicinal sweet around the globe known simply as Coltsfoot rock.
