eczema; skin eruption
Refers to eczema or a similar skin condition; the term is somewhat dated and may appear in older medical texts or historical contexts. In modern Japanese, 湿疹 (しっしん) is more common.
In old documents, the disease name '瘡' is recorded.
This medicine has long been said to be effective for skin eruptions.
Kana spelling is more common in everyday writing when referring to this condition.
The kanji 瘡 is composed of 疒 (sickness radical) and 倉 (warehouse), but the exact derivation is uncertain. The reading くさ is native Japanese, and the word is historically used for skin diseases.
