有个挂政府后缀的网站里面有这么个说法，我截取一小部分：
Impact
 
3. Injurious to people?
 
All parts of the plant are poisonous, and contact with the sap may cause skin rashes (Gardening Australia 2009). - Toxic, can cause allergies to humans throughout the year.

我找到一篇论文《Efficient in vitro multiplication in Ornithogalum ulophyllumHand.-Mazz. from twin scale explants》作者是Cigdem Alev Ozela,Khalid Mahmood Khawarb,Seher Karamanc,Mevlude Alev Atesa,Orhan Arslana，来源Scientia HorticulturaeVolume 116, Issue 1, 10 March 2008, Pages 109–112
 
我粗略翻了翻有这么一句
 “Some Ornithogalum plants are known to be poisonous, and several cardenolide glycosides have been isolated and identified ( Ghannamy et al., 1987)”
 
他们说有些这个属的植物有毒，有cardenolide glycosides被分离出来。
其中cardenolide glycosides是强心甾苷，毒性大小需要看计量。
