Saigon cinnamon is generally safe to eat in small amounts. One of the most important things to keep in mind, however, is that it is higher in coumarins than other types of cinnamon. Too much coumarin may cause liver damage. If you have a liver condition, you may want to limit your intake or avoid the use of cinnamon.
去年曾Recall肉桂苹果酱，原因是铅污染。此后扩大调查，发现六种牌子的肉桂粉中的若干批次有铅污染，虽然含量不高，但会在体内积累，长期食用会造成铅中毒。
六个牌子是：
La Fiesta, lot 25033, sold at La Superior SuperMercados
Marcum, best by 10/16/25 and 4/06/25, sold at Save A Lot
MTCI, sold at SF Supermarket
Swad, lot KX21223, sold at Patel Brothers
Supreme Tradition, best buy dates from 4/25 through 9/25, sold at Dollar Tree and Family Dollar
El Chillar, F275EX1026 and D300EX1024, sold at La Joya Morelense in Baltimore, Maryland
这个报道中有更多信息。
可能有人又会嘲笑怕这怕那，那就继续吃吧，随意。
另外，据以前TBz转发的一贴，只有斯里兰卡出产的肉桂是安全的，其他地方出产的都有比较高的生物毒性。
