[syns Stratiotes aquaticus Pall., Stratiotes ensiformis Gilib., Stratiotes generalis E.H.L.Krause]

The narrow sword-shaped leaves of this water plant bear sharp prickles along their edges, which can cause mechanical injury in those who pull the plant by hand.

According to Grieve (1931),the herb assuages swelling and inflammations in wounds; and an ointment made of it is good to heal them. The plant had in olden times the reputation of being an unfailing cure for all wounds made by iron weapons.
