Medicinal Monday - All About Water Pepper!

This plant, the Polygonum hydropiper, common in America is known by several interesting names including smartweed, Marash pepper, knotweed, and water pepper.  The Cherokee, Iroquois, and Malecite found many interesting uses for this herb that range from treating dropsy to using this plant as a poison!



About Water Pepper

This plant is usually found in the shallow water of ponds and in wetland areas. It prefers a wet mucky soil rich in organic material.  This summer annual grows to almost two feet high.  Its stem is hairless and can be red or green in color.  The leaves are smooth, hairless, and often olive-green in color with a base and membranous sheath that wraps around the stem.  The upper stems have spike-like racemes of flowers that range from two to three inches long.  Racemes are characterized by a flower cluster with separate flowers attached by short equal stalks at equal distances along a central stem (think Lily of the Valley). The flowers are greenish-white and consist of sepals with stamens but have no petals. The plant flowers from July through September. The flowers are replaced by black or dark brown seeds and spreads by reseeding themselves. 



Medicinal Uses
The Cherokee use this plant to treat painful urination in adults by making an infusion of this plant mixed with meal.  Another medicinal use is to treat pain, inflammation, and swelling by making a poultice of the entire plant mixed with meal.  An infusion of the root is given to children to treat diarrhea, and the leaves of this plant are rubbed on a child's thumbs to stop thumbsucking!  The Cherokee also use this plant to poison fish.  Known for its analgesic qualities, the Iroquois make a poultice of wet leaves and apply them to the forehead to treat headaches. A decoction is used to treat colds and coughs as well as children with swollen stomachs.  The Malecite use an infusion of dried leaves to treat dropsy.
