2.3 Poison hemlock (Conium maculatum) Conium maculatum is a tall, branched, biennial plant, usually 1–2.5m high, and thought to be one of the most toxic members of the family Apiaceae (formerly Umbelliferae) of plant kingdom. The stems are rigid, smooth, and hollow except at the nodes. The plant has a bitter taste and white flower. The leaves are large, triangular; fern like, and alternate on the erect stem. The plant usually grows in waste places where moisture may accumulate and protected from cultivation, damp ground, and banks of streams, rivers, road sides, woodland and pastures. Poison hemlock (Conium maculatum) has a worldwide distribution and reported as a very common weed in Europe, North and South America, North Africa, Australia …show more content…

The juice or the extract of Conium maculatum was allegedly administered to criminals or political prisoners in ancient Greece which the Greek philosopher Socrates was condemned to drink in 399 BC. The 70-year-old was found guilty of heresy in a trial in Athens. His sentence was death by hemlock, and he had to drink the poison by his own hand. Socrates drank up, then walked around until he noticed his legs were heavy (Holm, 1997; Scutchfield and Genovese, 1997). Symptoms described by Socrates were: a rapid loss of power of the lower extremities (muscular weakness), ataxia, staggering and trembling. As the effects ascended, there was loss of control of the upper extremities. Total paralysis of the legs and arms followed. There was loss of the power to chew and loss of sensation and the pupils became fixed. If ingested, conium will cause paralysis of various body systems. Finally, death was due to paralysis of respiration and asphyxia; but is aware of what is happening as the mind is unaffected until death is imminent the intellect was clear until death occurred (Panter and Keeler, …show more content…

The location of secretory structures and the presence of essential oils and alkaloids were investigated (Corsi and Biasci, 1998).The consumption of varying parts of the plants (leaves, fruits) can cause different degrees of clinical effects and there appears to be different susceptibility to toxicity between species. The primary time of year for poison hemlock is spring; often when there is insufficient forage available. At this time the plant may also be more palatable. The toxicity increases throughout the growing season and the roots become toxic only later in the year. Once dried, the toxicity is considered to be reduced but not eliminated. The plant causes different signs and lesions in different species of animals (Dougall and Maureen,
