- Datura (Datura stramonium)
Datura, also known as jimsonweed or devil’s trumpet, is a plant that contains tropane alkaloids like deadly nightshade. Its seeds and leaves, when consumed, can cause hallucinations, confusion, fever, and dangerous spikes in heart rate and blood pressure.
- Aconite (Aconitum spp.)
Aconite, commonly known as monkshood or wolf’s bane, is a highly toxic plant found in mountainous regions. All parts of the plant contain alkaloids that can lead to severe gastrointestinal disturbances, neurological symptoms, and heart issues. In extreme cases, ingestion can be fatal.
- Sago Palm (Cycas revoluta)
The Sago Palm, despite its name, is not a true palm but a cycad. Its seeds, leaves, and roots contain cycasin, a neurotoxin that can cause severe liver damage, vomiting, and in some cases, death. This plant is particularly dangerous to pets and small children, as its seeds may be mistaken for edible nuts.
- Poison Hemlock (Conium maculatum)
Poison hemlock is a deadly plant that resembles edible wild herbs like parsley, but it is far from safe to consume. It contains coniine and other alkaloids that can cause paralysis and respiratory failure in high doses.
