About
The character 瘙 denotes itching or an irritating skin condition, employed primarily in medical and dermatological contexts. As a standard phono-semantic compound, it is framed by the radical 疒, which indicates diseases and medical symptoms, thereby anchoring the character within the vocabulary of health and pathology. The enclosed component 蚤 means 'flea' and mainly provides the sound, but its association with the intense itching caused by flea bites adds a resonant semantic layer. The character appears predominantly in the compound 瘙痒 (sàoyǎng), the clinical term for pruritus.
