Toxicity

• To humans

  Sweet pea, the common name for Lathyrus odoratus 'Heathcliff', is mildly toxic to humans if ingested. The seeds and seed pods are the most toxic parts of the plant. Ingesting the seeds can lead to symptoms such as nausea, vomiting, abdominal pain, and convulsions in severe cases. Repeated consumption may result in a condition called lathyrism, which may cause muscle weakness and paralysis, particularly in the legs, due to the neurotoxin ODAP (beta-N-oxalyl-L-alpha,beta-diaminopropionic acid) present in the seeds.

• To pets

  Sweet pea, the common name for Lathyrus odoratus 'Heathcliff', poses a toxicity risk to pets if they consume the plant, particularly the seeds and seed pods. Symptoms of poisoning in pets can include lethargy, pacing, head pressing, tremors, seizures, and difficulty breathing. Continuous or large ingestion can lead to more serious neurological issues, such as lathyrism which affects the nervous system, potentially causing paralysis, especially in hind limbs. It's important to prevent pets from having access to sweet peas to avoid any toxic effects.
