Convallaria feu Sigillum Salomonis Ph. Edinb, (a) Polygonatum latifolium vulgare C. B. Convallaria multiflora Linn, Solomons-seal: a plant with unbranched stalks, bearing oval narrow leaves ribbed like those of plantain, generally all on one side: on the other side hang oblong monopetalous white flowers, two or more together, on long pedicles, followed each by a black berry: the root is white, thick, fleshy, with several joints, and some flat circular depressions supposed to resemble the stamp of a feal. It is perennial,; grows wild in woods, and flowers in May.
The roots of Solomons-seal are recommended externally as restringents; and internally as in-crassants and mild corroborants. They have little or no smell; to the taste they discover a considerable sweetness and viscidity, followed by a very slight impression of bitterishnefs and acrimony, which is dissipated by boiling. It is said that they have been used with success in the haemorrhoids (b). The flowers, berries, and leaves, are acrid and poisonous (c).
