heal
痊 centers on recovery from illness or injury: to heal or become well again.
痊 combines 疒 (sickness) with 全, which likely contributes both sound and the idea of completeness or wholeness, suggesting full recovery.
The sickness enclosure 疒 surrounds 全 (whole, complete). Picture sickness being completely surrounded and healed, making the person whole again.
For セン, imagine a cent (coin) being the price for a complete healing: cent -> セン, and the sickness is fully cured.
