Water hemlock roots contain lethal cicutoxin.

Eating the plant causes painful convulsions, abdominal cramps, nausea, and death. Survivors often have amnesia or tremors.

Macbeth’s warriors allegedly poisoned the Danes with nightshade wine. Sweet berries used to entice toddlers and adults to eat this deadly shrub. Night is a native of central and southern Eurasia with dull green foliage and glittering black poisonous fruit the size of cherries.

Loss of appetite, nausea, weakness, abdominal pain, reddish tongue, abnormal blood acidity, and mortality might result from consumption.

4. Cassava (Ricinus communis)

Castor Bean is an elegant African plant.

• Plant poison

Castor oil is made from processed seeds, which contain ricin and are lethal in small doses.
One or two seeds can kill a youngster or adult.

• Plant-based poison

These seeds contain the ribosome-inhibiting protein abrin. If the seeds are not damaged, they are not harmful.

Three micrograms of abrin can kill an adult, less than in one seed.

Abrine hinders protein synthesis in cells and can induce organ failure in four days, like ricin.
