Components

radical
sickness; illness radical
The sickness radical wraps the top and left, marking as a disorder — here a skin disease. Same radical as rash and ringworm.
phonetic
殿 diàn
palace hall; rear
Inside sits 殿 (palace hall), supplying the sound diàn directly with no tone change. It contributes no 'palace' meaning — it is purely the phonetic tag inside the sickness radical for this skin-patch word.
