Common name: Hare's-lettuce, Milk thistle, Sow thistle • Hindi: दूधी Dudhi • Manipuri: খোমথোক্পী Khomthokpi
Botanical name: Sonchus oleraceus Family: Asteraceae (Sunflower family)
The plant is an erect annual with simple branches. One particular feature
about this sow thistle is that most of the plant is smooth and glabrous -
without any hair or bristles. The stem is hollowed, and have a milky sap and
its lower part usually gets a purple-brown colour later in spring. The leaves
differ according age. The old (and hence lower) leaves are stalked, elongated
and deeply lobed. In fact each lobe, nearly oppositely arranged along the leaf
rachis, may appear to be a distinct leaf on its own. There are usually 2, 3 or
4 pairs of lobes per leaf and the terminal apical lobe is the largest and have
a shape of a rounded arrow. The younger leaves also possess similar but
smaller lobes. However these leaves are sessile, and have characteristic two
pointed lobes (auricles) embracing the stem. Colour of the leaves vary from
pale green to green-blue and may have a serrated outline but no prickles or
hair. The fruits are simple achenes, brownish in colour, and oval/oblong in
shape. They are wrinkled and possess obscure longitudinal ribs. At the apex
they have a beakless pappus which helps seed dispersal by wind. The shape of
involucral fruit is vase like - round bottomed with tapering apex and so
differs from the cylindrical shape of the bud.
Medicinal uses: Plant is useful in liver diseases. Leaves and roots
are used in indegestion as febrifuge; stem is used as sedative, tonic; root
extract is used in ointments for ulcers and wounds. Gum produced by
evaporating latex is used for ascites and hydrothorax.
