Tussilago farfara

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. The discovery of toxic pyrrolizidine alkaloids in the plant has resulted in liver health concerns.

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.

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.
