Medicinal Parts: The medicinal parts are the leaves and the
whole plant harvested during the flowering season.
Flower and Fruit: The greenish pink flowers are in sparse,
thin, hanging false ears. The 4-bract involucre is inconspicu-
ous with a reddish tip and is glandular-punctate. The flowers
are androgynous. There are 6 to 8 stamens, 2 of which have

Leaves, Stem and Root: The plant grows from 30 to 50 cm
high. The branched stems, which are from 60 to 90 cm long,
are first creeping and later semi-erect and often tinged red.
The leaves are oblong-lanceolate, short petioled, narrowed at
both ends and alternate; they are glandular and ciliate on the
under surface. The leaf sheaths at the base of the leaves.are
loose, glabrous and ciliated at the margin.
Characteristics: Smartweed has an extraordinarily hot,
pepper-like taste and is often used as a pepper substitute. The
plant has characteristic long, thinly curved, hanging, flower-
ing branches.

Habitat: The plant is indigenous to large parts of Europe,
Asian Russia and Arctic regions.

Production: Smartweed is the fresh plant, in flower, of
Polygonum hydropiper. The flowering herb is cut and
washed, the roots are removed and discarded and the herb is
dried in the shade.

times adultered with polygonum persicaria, P. mite and P.
minus.
