Taraxacum officinale - Dugdhapheni

Taraxacum, Dugdhapheni

Dugdhapheni or Taraxacum is a large genus of flowering plants in the family Asteraceae which consists of species commonly known as dandelion. They are native to Eurasia and North America, but the two commonplace species worldwide, T. officinale and T. erythrospermum, were imports from Europe that now propagate as wildflowers.

Description

The species of Taraxacum are tap-rooted, perennial, herbaceous plants, native to temperate areas of the Northern Hemisphere. The genus contains many species which usually (or in the case of triploids, obligately) reproduce by apomixis, resulting in many local populations and endemism. In the British Isles alone, 234 microspecies are recognised in 9 loosely defined sections, of which 40 are "probably endemic".

In general, the leaves are 5–25 cm long or longer, simple, lobed, and form a basal rosette above the central taproot. The flower heads are yellow to orange coloured, and are open in the daytime, but closed at night. The heads are borne singly on a hollow stem (scape) that is usually leafless and rises 1–10 cm or more above the leaves.

Many similar plants in the Asteraceae family with yellow flowers are sometimes known as false dandelions. Dandelions are very similar to catsears (Hypochaeris). Both plants carry similar flowers, which form into windborne seeds.

Uses

Historically, dandelion was prized for a variety of medicinal properties, and it contains a number of pharmacologically active compounds. Dandelion is used as a herbal remedy in Europe, North America, and China. It has been used in herbal medicine to treat infections, bile and liver problems, and as a diuretic.
