Common Knot-grass, in Latin Polygonum mas vul∣gare.

The Root is hard, woody, and single, and has many Fibres, and is of an astringent Taste. It has many Stalks; they are sometimes upright, but they oftner bend towards the Earth, or lie on it; they are above two Foot long; they are small, round, solid and smooth. The Leaves are placed alternately; they are oblong, narrow, and smooth, and are placed on very short Foot-stalks. From the Wings of the lower Leaves, at the Knots of the Stalks, come forth small Branches: And from the Wings of the Upper, two or three small Flowers together, on short Foot-stalks; they consist of five Leaves, and are of a light purple Colour. The Seeds are pretty large, triangu∣lar, and of a dark Chesnut-colour.

'Tis Vulnerary, Drying, and Astringent. 'Tis chief∣ly used for stopping all Fluxes. Outwardly 'tis used for Wounds and Ul∣cers, and for Inflammations of the Eyes. A certain Nobleman that vomited Blood, and had used other Medicines in vain, was much reliev'd by the Juice of this, in a little Styptick Wine.
