Solanum americanum is an annual or perennial herb that is native to California, and also found elsewhere in North America and beyond.
[Wikipedia] Toxicity: Research indicates the presence of toxic glycoalkaloids and there are warnings to be careful on the use of S. americanum as herbal medicine and food.[7] The green fruit is particularly poisonous and eating unripe berries has caused the death of children.[8] Ripe berries and foliage may also cause poisoning,[8] though the toxicity seems to diminish somewhat with ripening.[9] This is via high levels of the glycoalkaloids, solanine and solamargine.[10] Other toxins present in the plant include chaconine, solasonine, solanigrine, gitogenin and traces of saponins,[11] as well as the tropane alkaloids scopolamine and hyoscyamine (an isomer of atropine).
