Only the purified inner gel of Aloe vera is edible for humans; all other plant tissues are toxic to common domestic animals.

Toxicity Snapshot
First Aid & Prevention
First 30 Minutes
- • Remove any remaining aloe plant material from the affected person/animal's mouth and rinse thoroughly with clean water
- • Do not induce vomiting unless explicitly instructed to do so by a veterinarian or poison control professional
- • Collect a sample of the ingested plant to confirm identification for medical care providers
Contact Vet Immediately
- • Your cat, dog, or horse has ingested any part of an aloe plant other than purified edible gel
- • You observe symptoms including vomiting, diarrhea, lethargy, bloody stool, or discolored urine after exposure
- • A child has ingested large quantities of unprocessed aloe leaf and shows signs of gastrointestinal distress
Prevention
- • Keep potted aloe plants out of reach of cats, dogs, and horses to avoid accidental ingestion
- • Clearly separate purified edible aloe gel products from whole unprocessed aloe leaves that contain toxic sap
- • Never feed unprocessed aloe plant material to pets or livestock under any circumstances
Treatment & Prognosis
- • Administer decontamination measures such as activated charcoal under professional guidance to reduce toxin absorption
- • Provide symptomatic care including fluid therapy, anti-diarrheal medication, and gastrointestinal support as needed
- • Monitor kidney function and urinary output for patients presenting with increased urination or blood in urine symptoms
Professional Toxicology
• Saponin compounds irritate gastrointestinal mucosal membranes and disrupt cellular function
• Anthraquinone derivatives (e.g. aloin) have strong laxative effects and may cause kidney tissue damage with high or prolonged exposure
