Ingestion may cause mild gastrointestinal upset, but is generally not life-threatening.
Ingestion can result in mild symptoms like vomiting, diarrhea, or drooling. Rarely fatal but may require veterinary care.
Eating these plants can lead to more pronounced symptoms like abdominal pain, lethargy, or difficulty breathing. Veterinary intervention may be necessary.
Ingesting even small amounts can cause severe symptoms like organ damage, seizures, or cardiac failure without rapid treatment.
All parts of these plants are extremely poisonous to cats and can quickly lead to death, even with immediate veterinary care.

Poison hemlock has a long and notorious history. In ancient Greece, it was used to execute prisoners, most famously the philosopher Socrates in 399 BC. Throughout the centuries, poison hemlock has been employed as a medicine, cosmetic, and poison.
Despite its toxicity, poison hemlock was once used to treat ailments like bronchitis, asthma, and tumors. Its use as a sedative and antispasmodic continued into the early 20th century before safer alternatives were developed.
Today, poison hemlock is considered an invasive weed in many areas. Its similarity to other plants like parsley, fennel, and Queen Anne’s lace sometimes leads to accidental poisonings in humans and animals.
