The kanji 癒癒 is a phono-semantic compound (形声文字, keisei moji). The left side is the radical 疒 (やまいだれ, yamai-dare), which means "sickness" or "illness." The right side is 愈, which is a phonetic component, representing the sound and indirectly the meaning of "more and more" or "further." Together, they suggest a process of illness gradually becoming better, or recovering. Therefore, this character emphasizes the process of healing and getting better from illness or distress.
