治 — water radical 氵 + 台 (phonetic)
治 originally referred to the name of a river, written with the water radical 氵 for meaning and 台 as the phonetic component. From 'managing rivers' (flood control), the meaning broadened to 'govern, regulate, manage,' and later 'cure, heal' — all senses of bringing something unruly under control.
