"[Plin. Nat. 26.29.] - THE ASTRAGALUS: SIX REMEDIES.
Astragalus is the name of a plant which has long leaves, with numerous incisions, and running aslant near the root. The stems are three or four in number, and covered with leaves: the flower is like that of the hyacinth, and the roots are red, hairy, matted, and remarkably hard. It grows on stony localities, equally exposed to the sun and to falls of snow, those in the vicinity of Pheneus in Arcadia, for instance. Its properties are highly astringent; the root of it, taken in wine, arrests looseness of the bowels, having the additional effect of throwing downward the aqueous humours, and so acting as a diuretic; a property, in fact, which, belongs to most substances which act astringently upon the bowels.
Bruised in red wine, this plant is curative of dysentery; it is only bruised, however, with the greatest difficulty. It is extremely useful, also, as a fomentation for gum-boils. The end of autumn is the time for gathering it, after the leaves are off; it being then left to dry in the shade.”
