Are lemon bushes leaves poisonous

Lemon bush leaves, specifically from the lemon tree (Citrus limon), are not considered poisonous to humans. While the leaves may contain certain compounds that can cause mild irritation if ingested in large quantities, they are generally safe. However, it's always best to avoid consuming any plant material unless you are certain of its safety. If you have pets, consult a veterinarian, as some plants can be harmful to animals.
