Gentiana quinqueflora

Natural History.
      Five-flowered Gentian. Gall of the Earth. N.O. Gentianacae. Decoction of the herb.
      Tincture of fresh plant in flower (September, October).

      Intermittent fever.

      This unproved Gentian has a great popular reputation in Ohio and other parts of the United States as an antiperiodic and tonic.
      Hale quoted Yelvington of Susquehanna (who says he learned its value from a tribe of Indians) as saying "he has succeeded in obstinate intermittents where Quinine and other antiperiodics had failed.
      He used the decoction of the herb.
      A fluid extract or the saturated tincture is a better form for administration in fever.
      It is a valuable tonic for old cases of dyspepsia and torpid liver." It is a pleasant bitter, and appears to be, like the other Gentians, a positive tonic.
      Dr. Yelvington also used it in cases of infantile fever and cholera infantum.
      "As a tonic in enfeebled patients and in chronic diseases," he says, "it is a remedy par excellence, appearing to exert an action over the organs of nutrition and assimilation, as well as being a stimulant to the excretory organs."
