U+791C "礜" CJK Unified Ideograph-# Unicode Character

U+791C "礜" CJK Unified Ideograph-# is a Chinese character that primarily refers to a type of mineral, specifically a kind of stone or ore historically used in traditional Chinese medicine and alchemy, often associated with arsenic compounds or poisonous minerals due to its toxic properties. Composed of the radical for stone or rock and a phonetic component, this rare and complex character appears in classical texts and dictionaries, where it denotes a substance believed to have medicinal or transformative qualities, though its use is largely obsolete in modern contexts. The character exemplifies the depth of historical Chinese materia medica and the nuanced encoding of specialized vocabulary within the Unicode standard for CJK scripts.
