Sago Palm: One of the Most Dangerous Common Houseplants

Sago palms are popular ornamental plants both indoors and in warm-climate landscaping, and they're consistently near the top of veterinary toxicology lists for a reason: every part of the plant is toxic, but the seeds (sometimes called nuts) are the most concentrated, and dogs seem to find them particularly appealing to chew on.

The toxin causes severe liver damage, and this is one of the more sobering entries on this list — sago palm ingestion carries a meaningfully high fatality rate even with treatment, which makes early action more critical here than with almost anything else covered so far.

Symptoms to watch for: vomiting and diarrhea (sometimes bloody) within a few hours, followed by lethargy, jaundice (yellowing of the gums or eyes), increased thirst, and signs of liver failure over the following days.

What to do right now: any known or suspected ingestion of any part of a sago palm, including just chewing on a leaf, should be treated as an emergency immediately. This is not a plant where amount matters much — the concentration and severity of the toxin make even small exposures worth treating urgently.

When it's an emergency: always, for any part of the plant and any amount.
