This is a list of common plants containing poisonous parts that pose a serious risk of illness,  injury, or death to humans.

Poisonous Food Plants

  • Potato (Solanum tuberosum) Can contain the glycoalkaloid solanine; this develops as the eyes prepare to sprout chiefly as a result of exposure to light. Green tinged flesh is a sign that this process has begun.
  • Apple (Malus domestica) Seeds contain cyanogenic acids in them; although the amount found in most apples won't kill a person, with enough seeds, one could die from it.
  • Tomato (Solanum lycopersicum) Foliage and vines contain alkaloid poisons
  • Rhubarb (Rheum rhaponticum) Leaves contain oxalic acid salts
  • Cherry (Prunus cerasus), as well as other species such as peach, plum, almond and apricot (Prunus) Leaves and pits contain cyanogenic glycosides
  • Pokeweed (Phytolacca sp.) Leaves, berries and roots contain phytolaccatoxin and phytolaccigenin - toxin in young leaves is reduced with each boiling and draining.
