Arsesmart scientifically known as Persicaria hydropiper is an annual plant and a member of the knotweed or buckwheat Family(Polygonaceae).The plant grows in damp places and shallow water and is native to most of mainland Europe, North Africa, temperate parts of Asia, Australia,New Zealand and North America. Few of the popular common names of the plant are water pepper, Biting persicaria, Lakeweed, Curage, Red leaf, Marsh pepper smartweed, Marshpepper knotweed, annuals martweed, mild water pepper, akatade, water willow, redshank, Common smartweed, marshpepper smartweed, annual smartweed, marsh waterpepper, watersmartweed, biting knotweed, marsh pepper, knotweed, biting pepper, sickleweed and bog ginger. Persicaria, the generic name, relates the shape of leaves of this group of plants to those of a peach tree. The specific epithethy dropiper translates to water pepper. This flower gets its common name Water-pepper (sometimes written as Water Pepper) from its preference for wet habitats and the peppery taste of the leaves. It has some use as a spice because of its pungent flavor. The joints in the stem have produced the nickname red knees. Though several species possess similar properties, P. hydropiper is by far the most powerful in medicine. Most animals avoid the plant because of its burning flavor.

Plant Description

Arsesmart is an annual, glabrous plant that grows up to 20 to 70 cm (8 to 28 in) tall. The plant is found growing in soggy openings in woodlands, logged-over woodlands in floodplains, soggy alluvial meadows, seeps,edges of rivers and ponds, roadside ditches, poorly drained agricultural land,along creek, river, canal, stream banks, in marshes and swamps, in poorly drained hollows, and in seasonally flooded areas. Disturbed wetlands are preferred,although this plant also occurs in higher quality habitats. The plant grows well in most soils including silts, peats, loams and sands, and whilst tolerating a wide range of pH frequently grows better in more acid situations.The plant has taproot that may grow to over 1 m deep, though it is usually much shorter.


The main stem is often procumbent at the base, and may root from the lower nodes. It commonly branches at the lower nodes to produce several erect or ascending stems, 15-80 cm tall. Stems are smooth and hairless to very finely hairy, swollen at the nodes, green to red or light brown, and are surrounded above each node by cylindrical membranous ochreas which are 0.5-1 cm long with bristly tips. The stems normally branch towards their tips.


The single leaves have short stalks which taper into slender finely hairy glandular blades 4-10 cm long. Emerging leaves are rolled downwards at the edges. Modified stipules known as ochreae sheath the stem above the junction of stem and petiole. In P. hydropiper these are about 5 mm long with a fringe of hairs about the same length.


Inflorescence occur at the tips of all branches and in the upper leaf axils. Each is a slender (often nodding) spike of well-spaced green to pink flowers, 2-4 mm long, the outer parts of which are covered with dark glands. Flowering normally takes place from June through to the end of September.


Fertilized flowers develop into hard, usually triangular(also flattened), 2-3.5 mm long, dark dull brown to black nuts which remain surrounded in the dried flowers.


Sir Thomas Browne in The Garden of Cyrus (1658) asked: “Why Fenny waters afford the hottest and sweetest plants, as Calamus, Cyperus, and Crowfoot, and mud cast out of ditches most naturally produceth Arsmart?” In Japan leaves of a cultivar are used as a vegetable. Seeds of the water-pepper are also used in the popular Japanese wasabi sauce and sushi, tempura and sashimi dishes.
