Castor beans contain ricin, one of the most toxic substances known. A biphasic toxicity is described consisting of acute and potentially fatal gastroenteritis followed by damage to the viscera several days later. However, the most current review of the literature states that the above delayed toxicity has not been reported.
We report a 20-month-old girl with no gastrointestinal symptoms who developed reversible hepatotoxicity beginning 48-72 hours after the ingestion of castor beans.
It seems prudent to follow for several days any patients who actually chewed castor beans before ingestion.
蓖麻子含有蓖麻毒素，这是已知的最有毒物质之一。其毒性呈双相性，包括急性且可能致命的肠胃炎，随后在数天后出现内脏损伤。然而，最新的文献综述指出，上述延迟毒性尚未见报道。
我们报告一名20个月大的女童，在摄入蓖麻子后48 - 72小时开始出现可逆性肝毒性，摄入前无胃肠道症状。
对于任何实际咀嚼过蓖麻子再摄入的患者，持续观察数天似乎是谨慎的做法。
