Consulted references classify the plant as toxic or irritating for that pet type.
Drooling, vomiting, abdominal pain, and potential central nervous system depression.
The essential oils within the plant can cause irritation and systemic effects. Seek veterinary care if your dog shows signs of illness after exposure.
Most dogs that nibble the herb develop vomiting and diarrhoea. With concentrated-oil exposure, expect drooling, repeated vomiting, abdominal discomfort, and lethargy. The ASPCA names ascaridole, limonene, and p-cymene as the toxic essential-oil components.
Onset and recovery times for epazote in dogs are not well documented in the cited sources.
Call ASPCA Poison Control or your vet if your dog has consumed epazote essential oil, if vomiting or diarrhoea persists beyond a few hours, or if you see drooling, weakness, or wobbliness.
Dogs: epazote is on the ASPCA toxic-plant list for dogs. A few chewed leaves usually means GI upset, but ingestion of concentrated epazote oil — the form used in some herbal preparations — can be considerably more serious because of its ascaridole content.
