CHAP. 113.—THE PLANT CALLED IMPIA: TWO REMEDIES.
The plant called “impia”427 is white, resembling rosemary in appearance. It is clothed with leaves like a thyrsus, and is terminated by a head, from which a number of small branches protrude, terminated, all of them, in a similar manner. It is this peculiar conformation that has procured for it the name of “impia,” from the progeny thus surmounting the parent. Some persons, however, are of opinion that it is so called because no animal will touch it. Bruised between two stones it yields an effervescent juice, which, in combination with wine and milk, is remarkably efficacious for quinzy.
There is a marvellous property attributed to this plant, to the effect that persons who have once tasted it will never be attacked by quinzy; for which reason it is given to swine: those among them, however, which refuse to take it will be sure to die of that disease. Some persons too are of opinion that if slips of it are put into a bird’s nest, they will effectually prevent the young birds from choking themselves by eating too voraciously.
