What is "raphany"

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.
