healing, cure, quench (thirst), wreak
癒 centers on restoration from harm or need: healing illness, curing pain, or soothing a deep lack such as thirst. The rare sense 'wreak' is likely a misassignment or obscure extension and does not fit the core idea.
癒 combines 疒 (sickness) with 愈, which likely contributes both sound and the idea of getting better.
The sickness enclosure 疒 wraps around 愈, a shape associated with getting better. Picture illness being surrounded and gradually healed.
For ユ, imagine you helping someone heal: you -> ユ, and your care cures the sickness inside 癒.
