Similar to cyclopamine, which also occurs in the genus ''Veratrum'', it is a teratogen implicated in birth defects when consumed by animals during a certain period of their gestation.{{cn|date=January 2025}} __TOC__

==Physiological effects == Jervine is a potent teratogen causing birth defects in vertebrates. In severe cases it can cause cyclopia and holoprosencephaly.{{cn|date=January 2025}}

== Mechanism of action == Jervine's biological activity is mediated via its interaction with the 7 pass trans membrane protein smoothened. Jervine binds with and inhibits smoothened, which is an integral part of the hedgehog signaling pathways.<ref>{{cite journal |author1=Chen, J |author2=Taipale, J |author3=Cooper, M. | title = Inhibition of Hedgehog Signaling by direct binding of Cyclopamine to Smoothened | journal = Genes Dev. | year = 2002 | volume = 16 | pages = 2743–2748 | pmid = 12414725 | issue = 21 | doi = 10.1101/gad.1025302 | pmc = 187469}}</ref> With smoothened inhibited, the GLI1 transcription cannot be activated and hedgehog target genes cannot be transcribed.{{cn|date=January 2025}}
