First Aid & Prevention

First 30 Minutes

• Rinse the mouth of the exposed individual/animal with clean water if large amounts of plant material were ingested
• Monitor for rare signs of mild digestive discomfort for 2 to 4 hours post-exposure
• Clear remaining plant debris from the area to prevent further unnecessary intake

Contact Vet Immediately

• If the affected animal shows persistent vomiting, diarrhea, or lethargy lasting more than 6 hours post-ingestion
• If the animal consumed the plant alongside other known toxic substances or extremely large quantities of material

Prevention

• Only restrict access if your pet has a history of overeating non-food vegetation leading to digestive distress
• Store harvested edible rhizomes separately from ornamental plant material to avoid accidental mix-ups

Treatment & Prognosis

• Provide supportive care only if mild digestive symptoms occur, including access to fresh clean water and rest
• No specific antidote is required, as no toxic effects are expected from exposure to this plant

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Domestic Rabbit: Non-toxic; may be safely fed as part of a varied forage diet in moderate quantities

Guinea Pig: Non-toxic; no reported adverse effects from casual ingestion of leaves or rhizome pieces

Backyard Poultry: Non-toxic; leaf and rhizome material is safe for consumption in small amounts as part of a balanced diet

Confusion Risk

The following plants look similar and may be confused:

True Arrowroot Maranta arundinacea

Confused due to shared 'Arrowroot' common name and similar edible starchy rhizomes; key difference is true arrowroot belongs to the Marantaceae family, not Cannaceae

Ornamental Canna Lily Canna indica

Visually nearly identical due to shared large foliage and bright inflorescences; key difference is some ornamental Canna indica cultivars have higher latex content that may cause mild digestive upset
