Tordylon is, according to some authorities, the seed of sili,434 while according to others it is a distinct plant,435 known also as “syreon.” I find no particulars relative to it, except that it grows upon mountains, and that the ashes of it, taken in drink, act as an emmenagogue and facilitate expectoration. It is stated also, that for this last purpose the root is even more efficacious than the stem; that the juice of it, taken in doses of three oboli, cures diseases of the kidneys; and that the root is used as an ingredient for emollient plasters.
