《史记·七十列传·苏秦列传》
苏秦说： 我听说饥饿的人，宁愿饥饿而不吃乌头这种有毒植物的原因，是因为它越是能填满肚子就和饿死的灾祸越是没有区别啊。
苏秦曰： 臣闻饥人所以饥而不食乌喙者，为其愈充腹而与饿死同患也。
Su Qin explained, “I've heard that starving people prefer to starve rather than eat the wolfsbane plant, because filling one's stomach is little different from starving to death with wolfsbane poisoning.”
