DESCRIPTION
Medicinal Parts: The medicinal parts are the fresh leaves
and the whole herb.
Flower and Fruit: The plant has small greenish unisexual,
dioecious flowers growing in narrow, loose panicles. There
are 6 tepals. The 3 inner ones are longer, closer together, and
turn red when the fruit ripens. When mature they are often
red-tinged, membranous, entire-margined and have a scale-
like downwardly curved welt at the base. The three
outermost tips are revolute. There are 6 stamens and 3 styles
with a paintbrush-like stigma. The fruit is a triangular,
brown-black nut enclosed in the wing-like enlarged inner
tepal.

Leaves, Stem and Root: The plant can grow up to 100 cm
high. The leaves alternate on the erect, grooved stems, which
are unbranched up to the panicles. The leaves are fleshy,
grass green, hastate or spit-shaped. The lower leaves are
long-petioled; the upper ones are short-petioled, sessile and
clasping. There is a membranous, dentate or fringed cone at
the base of the leaves.

Characteristics: The stem is red-tinged, and the herb has a
sour taste. It gets its acidity from the same salt that is present
in Rhubarb.
