Poison Ivy
The surprisingly poisonous plants that are right here in the UK.
Fans of Agatha Christie will be aware that nefarious characters of yesteryear had a penchant for poison. Terrifying tinctures, savage serums and potions of ill portent were popular in the periods before modern medicine, and with the lack of laboratories to create chemicals, apothecaries and poisoners relied on humble plants to both heal and kill.
Foxglove
A striking plant (pictured, top) with tall spikes of tubular flowers, often seen in gardens and woodlands. Despite its allure (and charming name), every part of the foxglove is highly toxic. It contains compounds called cardiac glycosides, which can cause nausea, vomiting, hallucinations, and potentially fatal heart problems.
Giant hogweed
An invasive species that can reach up to 5 metres in height, its sap contains toxic chemicals called furanocoumarins, which can cause severe skin burns and blistering when exposed to sunlight. Contact with this plant should be avoided, and any exposure should be treated with immediate medical attention.
Deadly Nightshade
Also known as belladonna, this plant bears attractive, shiny black berries and purple bell-shaped flowers. However, its beauty masks a deadly secret; the entire plant is highly toxic, containing tropane alkaloids that can cause dilated pupils, sensitivity to light, blurred vision, tachycardia, loss of balance, and hallucinations. Ingesting even small amounts can be fatal, but you can’t say the name didn’t warn you.
Yew
The yew tree is a common sight in churchyards and parks, known for its evergreen foliage and red berries. But despite its pleasant facade, all parts of the yew, except for the flesh of the berries, contain toxic alkaloids called taxines. These can cause symptoms ranging from dizziness and dry mouth to severe cardiac and respiratory distress, potentially leading to death if ingested. Who knew?
Monkshood
Lily of the valley
This delicate plant is often associated with springtime and is commonly used in floral arrangements. However, it contains cardiac glycosides similar to those found in foxglove. Ingesting any part of the plant can lead to symptoms such as nausea, vomiting, diarrhoea, and irregular heartbeats.
Hemlock
Hemlock is a tall, branching plant with small white flowers and fern-like leaves. It is notorious for its role in the execution of the philosopher Socrates. The plant contains potent alkaloids, including coniine, which can cause symptoms such as muscle paralysis, respiratory failure, and death. Not a smart way to die.
