qiú is archaic — preserved chiefly in traditional Chinese medicine vocabulary as a diagnostic term for chronic nasal symptoms. The compound
鼽嚏 (nasal-discharge-and-sneezing) names a TCM pattern roughly corresponding to allergic rhinitis. Modern Mandarin uses
鼻塞 (stuffy nose),
流鼻涕 (runny nose), or
鼻炎 (rhinitis) —
鼽 is essentially never used in everyday speech or modern biomedical writing.
