CHAP. 46.—THE APIOS ISCHAS, OR RAPHANOS AGRIA: TWO
The apios ischas or raphanos agria,1
throws out two or
three rush-like branches of a red colour, creeping upon the
ground, and bearing leaves like those of rue. The root
resembles that of an onion, only that it is larger, for which
reason some have called it the "wild radish." The interior
of this root is composed of a mammose substance, containing
a white juice: the outer coat is black. It grows in rugged,
mountainous spots, and sometimes in pasture lands. It is
taken up in spring, and pounded and put into an earthen vessel,
that portion of it being removed which floats upon the surface.
The part which remains acts purgatively, taken in doses of
an obolus and a half in hydromel, both as an emetic and by
stool. This juice is administered also, in doses of one acetabulum, for dropsy.
The root of this plant is dried and powdered, and taken in
drink: the upper part of it, they say, carries off bile by acting
as an emetic, the lower part, by promoting alvine evacuation.
