Warnings: Research indicating the presence of toxic glycoalkaloids prompted a warning to be careful on the use of S.americanum as herbal medicine and food. The green fruit is particularly poisonous. Ripe berries and foliage may also cause poisoning. This is via high levels of the glycoalkaloids, solanine and solamargine, as well as the tropane alkaloids scopolamine (hyoscine) and hyoscyamine (an isomer of atropine).
