Xǔ Xiàochóng 許孝崇, fl. mid-7th century, Imperial Physician (尚藥奉御) under Táng Gāozōng, and one of the senior medical members of the editorial committee that produced the Xīnxiū běncǎo (KR3ec004) in 659. He held the further rank of Tàizhōng dàfū 太中大夫. Kǒng Zhìyuē’s preface names him alongside Lǐ Jì and Zhǎngsūn Wújì as one of the principal supervising signatories. No independent biography survives; he is known only from the Xīnxiū běncǎo’s editorial list and a handful of incidental imperial-physician references.
