What to do

Treat as an emergency for significant ingestion β€” nicotine acts quickly and can affect heart rate and the nervous system in a biphasic pattern (stimulation followed by depression).

Toxic component and mechanism

The toxic component in Nicotiana is nicotine and related alkaloids.

What makes this plant different

Ornamental Nicotiana (Tree Tobacco) contains real nicotine, and its rapid absorption means symptoms can progress faster than with many slower-acting plant toxins β€” a reminder that decorative tobacco relatives carry the same core chemistry as the cigarette plant, just packaged as a garden flower.
