Usage examples of "hot-spirited".

Old authors say: 'this fiery and hot-spirited herb is not fit to be given inwardly, but that an ointment of the leaves and flowers will raise a blister and may be applied to the nape of the neck to draw rheum from the eyes,' and that mixed with a little mustard it raises a blister as perfectly as the Spanish Fly.
