Raphany \Raph"a*ny\ (r[a^]f"[.a]*n[y^]), n. [Cf. F. raphanie.]
   (Med.)
   A convulsive disease, attended with ravenous hunger, not
   uncommon in Sweden and Germany. It was so called because
   supposed to be caused by eating corn with which seeds of
   jointed charlock (Raphanus raphanistrum) had been mixed,
   but the condition is now known to be a form of ergotism.
