Manchineel

Hippomane mancinella

Identified By Marcs

The manchineel is widely recognized as one of the most dangerous trees in the entire world, native to tropical regions of southern North America, Central America, the Caribbean, and northern South America. Every single part of this remarkable yet perilous tree, including its bark, leaves, flowers, and fruits, contains a powerful and highly toxic milky sap that can cause severe chemical burns, inflammation, and temporary or permanent blindness upon contact with human skin or eyes. Despite its extreme toxicity, the manchineel plays a vital ecological role in coastal environments by stabilizing sandy beaches and acting as an effective natural windbreak against severe tropical storms and hurricanes.

Also known as: Beach Apple Little Apple of Death

Toxicity & Safety

Is Manchineel toxic to pets?

Yes, toxic to pets.

The manchineel tree is extraordinarily toxic to all domestic pets and animals. Ingestion of any part of the plant, especially the leaves or the small green apple-like fruits, can lead to severe gastrointestinal distress, intense internal burning, profuse salivation, vomiting, and potentially fatal systemic shock. Merely brushing against the foliage or getting the caustic sap on an animal's fur and skin can cause severe dermatitis, painful blisters, and intense irritation. Pet owners must ensure their animals are kept far away from these trees, particularly in coastal areas where the tree naturally grows.

Is Manchineel toxic to humans?

Yes, toxic to humans.

Manchineel is notoriously dangerous to humans due to its highly toxic sap, which contains phorbol and other potent irritants. Contact with the skin causes severe, burn-like blistering, while getting the sap in the eyes can result in temporary or permanent blindness. Ingesting its sweet-smelling fruit causes severe pain, throat closure, and life-threatening digestive complications. Standing beneath the tree during rainfall is also hazardous, as raindrops mixed with the sap dripping from the leaves can burn human skin. Burning the wood produces toxic smoke that can permanently blind and severely injure anyone nearby.

Is Manchineel safe during pregnancy?

Caution advised during pregnancy.

Exposure to the extreme toxins and systemic irritants found within the manchineel tree poses severe health risks to pregnant individuals. The powerful chemical compounds contained in the sap can induce significant systemic reactions, severe allergic dermatitis, and intense physical stress that may indirectly jeopardize pregnancy health. Due to the extreme potency of the plant's poisons and the lack of safe exposure thresholds, pregnant individuals must strictly avoid any contact with the tree, its sap, its smoke, or its fruit to prevent catastrophic health complications.
