Krameria is obtained from the root of the shrub krameria triandra, of the natural order Polygaleae, native of Peru. It is in the form of cylindrical pieces, of the thickness of a quill, with many branches of a light red color within and crossed by a reddish-brown bark. The root is without odor, and of an astringent and somewhat bitter-sweetish taste.
Krameria is a powerful astringent, its medicinal property being due to tannic acid, of which it contains about forty per cent. There is also present an odorous principle, wax gum, and a peculiar acid known as krameric acid. When chewed it imparts a red tinge to the saliva. It imparts its properties very readily to alcohol, but less so to both cold and boiling water.
Krameria is employed internally for its astringent and a slightly tonic effect in the treatment of diarrhoea, dysentery, passive hemorrhages, menorrhagia, leucorrhoea, etc. Externally, in the form of powder, tincture and infusion, in the treatment of ozaena, ophthalmia, etc., and as an enema in hemorrhoids, fissures of the anus, sore nipples, leucorrhoea, etc., etc.
