風癎（上音封說文云風動蟲生故蟲八月而化從虫𠘨聲也下限姦反聲類云小兒病也從疒間聲也疒音女厄反像倚臥之形也）。

Wind epilepsy (風癎: the first character is pronounced 封; Shuowen says, “Winds move and insects are born; thus insects transform in the eighth month; it takes 虫 with 𠘨 for phonetic.” The second character has the fanqie 限 + 姦; Shenglei says, “An infantile disease; it takes 疒 with 間 for phonetic.” 疒 has the fanqie 女 + 厄, resembling the posture of reclining in sickness).
