（宋代《开宝本草》记载）
【释名】圣知子（出自《日华子本草》）、圣先子。
苏颂《本草图经》记载：相传取两枚果实缀在衣领上，如果遇到蛊毒，就能听到声响，从而预先知晓，因此得名。
李时珍说：“仙沼”，怀疑是“仙枣”的讹误。
【集解】苏颂《本草图经》记载：预知子有皮壳，其果实形状像皂荚子。
苏颂又说：以前不记载它出产的州县，现在淮、蜀、汉、黔、壁等州都有出产。它是蔓生植物，依附在大树上生长。叶子绿色，呈三角形，正面颜色深背面颜色浅。七月、八月结果实成房状，初生时为青色，成熟后为深红色。每房有五到七枚种子，像皂荚子一样，呈斑褐色，光泽润泽如飞蛾之翅。它的功效胜过果实本身。山民称它为“圣无忧”。
双仁的种子可以带壳服用。
【气味】味苦，性寒，无毒。
陈藏器《本草拾遗》说：性温。双仁的可带壳服用。
【主治】杀虫疗蛊，治疗各种毒邪。（出自《开宝本草》）。治疗各种风邪，补益五劳七伤，其功效无法详尽叙述。治疗癖气块（积聚），消除宿食，止住烦闷，通利小便，催生，治疗中恶失音，促进头发再生，治疗天行温疾（流行性温热病），涂抹治疗一切蛇虫蚕咬伤，治疗各种疾病，每天吞服二至七粒，不超过三千粒，即可永远痊愈（出自《本草拾遗》）。

耳卒聋闭（突然耳聋闭塞）：八、九月取石榴，开一个小孔，保留盖子，倒入米醋装满，盖好，用面糊包裹，在火中煨熟取出，放入少许……（原文此处似有缺漏或排版错误，结合上下文推测可能涉及药物混合，但依原文仅译可见部分）仙沼子、黑李子……
眉落声变（眉毛脱落声音改变）：预知子膏：用预知子、雄黄各二两，研为细末。用乳香三两，同水一斗，在银锅中煮至五升。加入上述两种药末，熬制成膏，用瓶子盛装。每次服用一匙，用温酒调服。会有如马尾般的虫子，随大便排出。（出自《太平圣惠方》）

Each pod contains five to seven seeds, resembling soap beans, mottled brown, glossy like flying insects. Its efficacy surpasses that of the fruit itself. Mountain people call it "Sheng Wuyou" (Sage Without Worries).
