Beautiful things are not always good ▪ Arum italicum, A. maculatum, pianta velenosa ⑭

1Arum is a tuberous herbaceous perennial. Leaves and flowers emerge from tubers and each flower consists of an erect, finger-like spadix covered with minute, creamy white flowers and a large light green bract which partially envelops the spadix. After bloom, leaves and bract die leaving only the spadix which develops attractive, bright orange-red berries [1].

All plant parts are toxic: tubers, leaves, bracts, flowers, berries.

All parts are abundant in saponins (arin), alkaloids (n-methyl-coiine), calcium oxalates which have needle-shaped crystals which irritate the skin, mouth, tongue, throat and result in 3swelling of throat, difficulty breathing, burning pain and upset stomach [2].
