CHAP. 42.—THE TITHYMALOS HELIOSCOPIOS : EIGHTEEN REMEDIES.
A fourth kind of tithymalos1
is known by the additional
name of "helioscopios."2
It has leaves like those of purslain,3
and some four or five small branches standing out from the root,
of a red colour, half a foot in height, and full of juice. This
plant grows in the vicinity of towns: the seed is white, and
are remarkably fond of it. It receives its additional
name of "helioscopios" from the fact that the heads of it turn5
with the sun. Taken in doses of half an acetabulum, in
oxymel, it carries off bile by stool: in other respects it has
the same properties as the characias, above-mentioned.
