First Aid & Prevention

First 30 Minutes

• Remove any remaining plant material from the subject's mouth and surrounding area.
• Rinse the mouth thoroughly with clean cool water if residual plant matter is present.
• Monitor for unusual signs including drooling, vomiting, or lethargy for 2 to 4 hours post-ingestion.

Contact Vet Immediately

• If your pet or livestock ingests large quantities of the plant and develops persistent vomiting, diarrhea, or lethargy.
• If you are unsure if the ingested plant is Brachychiton rupestris or a potentially toxic lookalike species.

Prevention

• Do not use Brachychiton rupestris as a feed source for any pets or livestock.
• Learn to distinguish Brachychiton rupestris from other Brachychiton species via its distinctive swollen mature trunk to avoid lookalike exposure.
• Keep potted specimens out of reach of young pets that may chew on plant material out of curiosity.

Treatment & Prognosis

• Provide supportive care including fluid administration for any rare gastrointestinal adverse reactions.
• Administer activated charcoal only if large quantities are ingested and advised by a veterinarian or medical professional.
• Rule out exposure to toxic lookalike species if severe symptoms develop following ingestion.
