Liliaceae - syn. Sabadilla officinale (Cham. et Schlecht.) Brandt, Veratrum officinale Schlechtd.; Sabadilla, Sabadille, Mexikanisches Läusekraut
Perennial herb, native in Central America and northern South America, up to 2m high; stem leafless; leaves forming a basal rosette, up to 1.50m long; flowers small, greenish-yellow.
„Sabadill contains toxic steroid alkaloids in all plant parts, but especially in the „rhizome“ and seeds. They are derived like most veratrum alkaloids (like white hellebore) from C-nor-homo-cholestane. The seeds contain 1 to 5% of the mixture of alkaloids, named veratrine. Therein several veracevin esters were deteted (cevadin, veratridine)… Veratrine is irritant to the mucous membranes in the nose and produces sneezing. When ingested, it can cause vomiting, collapse, unconsciousness and even death. It paralyzes the peripheral nerve endings and striated muscles. In therapeutic doses it temporarily lowers blood pressure.“ http://de.wikipedia.org/wiki/Sabadill
