Amianthium muscitoxicum
Plante vivace toxique des forêts ouvertes de l'est de l'Amérique du Nord, historiquement utilisée comme poison à mouches dans la tradition populaire.
Amianthium muscitoxicum is a highly toxic perennial herb native to eastern North America, historically employed as a fly poison in folk traditions and by Native Americans. Its primary active compounds include the steroidal alkaloids jervine and cyclopamine, which are responsible for its potent neurotoxic and teratogenic effects. Despite its historical use as an insecticide, there is no established safe medicinal application due to its extreme toxicity.
The alkaloids jervine and cyclopamine exert toxicity through multiple mechanisms. Cyclopamine is a well-characterized antagonist of the Hedgehog signaling pathway, binding to Smoothened (SMO) and inhibiting downstream Gli transcription factors, leading to severe developmental defects such as cyclopia. Jervine modulates voltage-gated sodium channels and inhibits acetylcholinesterase, resulting in neurotoxic and cardiotoxic effects including paralysis and respiratory failure. These combined actions render the plant lethal upon ingestion.
