There is no evidence to suggest that the African Fern Pine (Afrocarpus falcatus) is poisonous to humans or animals. However, like all plants, ingestion of large amounts of its leaves or berries may cause gastrointestinal upset. It is always best to keep plants out of reach of children and pets to prevent accidental ingestion. Additionally, the African Fern Pine is a large tree and may pose a hazard if it falls or sheds large branches, so care should be taken when planting it near structures or high-traffic areas.
