The toxins also remain stable when dried and stored, with bulbs remaining toxic for two decades after collection. [31] The seeds and the bulbs are the most toxic parts of the plants. [7] A survivor of poisoning said of the experience, "My mouth got tingly, and later the sensation moved down my throat." [32] Human poisonings are rare.
