Sécurité

People: The seeds are toxic if ingested in large quantities, and the fruit pulp can cause skin irritation.
Pets: The seeds and leaves are toxic to cats and dogs if ingested.
Children: Keep children away from the fallen fruit, as the pulp is highly irritating to skin and toxic if eaten.
Contact allergens: The pulp of the female fruit contains ginkgolic acids which are potent skin irritants.
Airborne allergens: Male trees produce pollen that can trigger seasonal allergies in sensitive individuals.
