About
The character "疬" denotes scrofula, a lymphatic disease, and appears primarily in the compound "瘰疬". Its traditional form, "癧", is structured with the disease radical "疒" and the phonetic component "歷", which indicates pronunciation. In the simplified form "疬", the phonetic element is replaced by "厉", a component that also signals sound while reducing complexity. Historically, the character's meaning has remained specific to this medical condition, with no broad semantic expansion.
