ACTION AND USES.--Qussia is a bitter stomachic and tonic. It resembles
gentian and calumba. It is prescribed for the several domestic animals
in dyspepsia, loss of appetite and convalescence from debilitating
disorders. Qussia is the most efficient vermicide in our possession for
the destruction of Oxyuris curvula, horse; and O. vermicularis, dog, in
the lower bowel. An infusion is employed for this purpose, made by
soaking qussia chips in cold water (two drachms of the qussia to one
pint of water) for half an hour. The rectum should be first thoroughly
washed out with soap and water and one-half pint of this infusion is
given in enema to dogs; two quarts to horses. The infusion is a narcotic
poison for flies and other insects.
