《魏书·列传·卷七十九》
徐謇合和药剂，治疗疾病的效果比李更为精妙，但他的性情十分古怪，如果接待不如他的意愿，即使如王公那样尊贵的人，也不肯替他治病。
謇合和药剂，攻救之验，精妙于脩，而性甚秘忌，承奉不得意者，虽贵为王公，不为措疗也。
Xu Qian combined medicinal compounds, and his treatment of illness was even more refined than Li, but his personality was very eccentric. If the hospitality did not go according to his wishes, he would refuse to treat even people as respected as civil and military officials.
