Antiaris toxicaria(见血封喉树) , commonly known as the upas tree or poison tree, is a large tree species belonging to the Moraceae family. It is well-known for its toxic latex, which has historically been used for hunting and warfare, as well as its potential medicinal uses. Here’s some information on Antiaris toxicaria, particularly in relation to Yunnan, China:
General Information about Antiaris Toxicaria:
- Scientific Name: Antiaris toxicaria
- Common Names: Upas tree, poison tree, antiaris
- Family: Moraceae
- Native Range: It is native to tropical regions, including parts of Southeast Asia, Africa, and northern Australia. The tree also grows in southern China, including Yunnan Province.

Characteristics and Uses:
- Toxic Latex: The most notable feature of Antiaris toxicaria is its latex, which contains toxic compounds like antiarin. This latex can cause severe irritation upon contact with the skin and is highly toxic if ingested. Historically, it was used by indigenous peoples to poison arrows for hunting and warfare.
- Medicinal Uses: Despite its toxicity, the tree has been used in traditional medicine. In some cultures, the latex and other parts of the tree have been used to treat various ailments, such as skin diseases, fever, and as a sedative. However, such uses require extreme caution due to the tree’s toxic nature.
- Wood: The wood of Antiaris toxicaria is relatively soft and lightweight, making it suitable for construction and crafting purposes, though its toxicity can limit its use.
- Ecological Role: In its natural habitat, the tree plays a role in the forest ecosystem, providing shelter and food for various wildlife. It is also valued for its ecological benefits, such as carbon sequestration.
Antiaris Toxicaria in Yunnan:
- Distribution: In Yunnan, Antiaris toxicaria is found in tropical and subtropical forests, especially in the southern parts of the province, where the climate is suitable for its growth. Yunnan’s biodiversity-rich environment makes it a suitable habitat for such species.
- Conservation: While not globally endangered, habitat loss due to deforestation and agricultural expansion can threaten local populations. Conservation efforts focus on preserving natural habitats and maintaining biodiversity in regions like Yunnan.
Safety Precautions:
- Handling: Due to the toxic nature of the latex, caution should be exercised when handling any part of the tree. Direct contact with the latex should be avoided, and protective gloves should be worn if necessary.
- Medical Attention: In case of accidental exposure, especially ingestion, immediate medical attention is required due to the potential severity of poisoning.
Antiaris toxicaria is a fascinating yet dangerous species, highlighting the complex interactions between nature and traditional human practices. It is a part of Yunnan’s rich floral diversity and contributes to the ecological and cultural heritage of the region.
