But, despite their beauty, there’s a dark side to the robinia tree that many people may not be aware of. Some experts say that this tree is highly toxic and can cause serious health problems if ingested.
The debate over the toxicity of robinia trees has been going on for years. While some people believe that they are harmless, others warn that they can be deadly. The truth is somewhere in between.

If you’re concerned about the safety of your robinias, consider having a professional examine them for signs of damage or disease.

By taking the right precautions, you can enjoy all that these trees have to offer without worrying about their potential dangers.
Robinia Tree Identification
Robinia trees, also known as black locust trees, are medium-sized deciduous trees that can grow up to 80 feet tall. The trees are native to southeastern United States and are commonly found in the Appalachian Mountains. They were introduced to Europe in the early 17th century and are now commonly found in parks and gardens all over the world. Robinia trees are known for their attractive white flowers that bloom in the late spring to early summer.
- The leaves of a Robinia tree are pinnately compound, meaning they are divided into leaflets arranged on each side of a central stalk called the rachis. A single leaf can have up to 21 leaflets.
- The flowers of a Robinia tree are white, fragrant and pea-shaped. They grow in clusters that can be up to 8 inches long and appear in late spring or early summer.
- The bark of a young Robinia tree is smooth and greenish-brown, while the bark of a mature tree is deep furrowed with rough ridges. The wood of a Robinia tree is hard, dense and rot-resistant, making it popular for outdoor furniture and fence posts.
Symptoms of Robinia Tree Poisoning in Humans
Robinia trees, also known as black locust trees, are native to North America and are known for their beautiful white flowers and hard wood. However, despite their aesthetic appeal, they are not without danger as they contain the toxin robin, which can cause harm to humans if ingested or contact is made with the tree’s sap or bark.
- Oral symptoms: Ingestion of any part of the robinia tree, including the flowers, leaves, seeds, and bark, can result in a variety of symptoms, including nausea, vomiting, abdominal pain, and diarrhea. The severity of these symptoms typically depends on the amount of toxin ingested and the age and health status of the individual.
- Respiratory symptoms: Inhaling the bark or flowers of the robinia tree can cause respiratory symptoms, including coughing, wheezing, and shortness of breath. These symptoms are caused by the release of the toxin into the airways and can be severe in some cases.
- Skin symptoms: Contact with the sap or bark of the robinia tree can cause skin irritation and rash. The severity of these symptoms depends on the level of exposure and may range from mild irritation to severe rash and blisters.
If you suspect that you or someone you know has been poisoned by a robinia tree, seek medical attention immediately. Treatment may involve symptomatic relief, such as anti-nausea medication and pain relief, or in severe cases, activated charcoal or gastrointestinal decontamination to remove the toxin from the body.
It is important to keep in mind that while robinia tree poisoning can cause significant harm to humans, it is a relatively rare occurrence. However, it is still important to exercise caution when interacting with these trees and to seek medical attention if you experience any symptoms of poisoning.
| Symptoms | Cause |
|---|---|
| Nausea, vomiting, abdominal pain, and diarrhea | Ingestion of any part of the robinia tree |
| Coughing, wheezing, and shortness of breath | Inhaling the bark or flowers of the robinia tree |
| Skin irritation and rash | Contact with the sap or bark of the robinia tree |
Overall, while the robinia tree is a beautiful addition to any garden or landscape, it is important to be aware of the potential risks associated with them. By taking the necessary precautions and seeking medical attention if needed, you can enjoy the beauty of these trees without putting yourself at risk.
Symptoms of Robinia Tree Poisoning in Animals
Robinia, commonly known as black locust trees, are deciduous trees with white flowers that bloom in the spring. While their wood and bark have been used in traditional medicine, it’s important to note that all parts of the robinia tree contain a toxic substance called robin. This toxin can cause serious health problems in animals that have ingested it.
Here are the symptoms of robinia tree poisoning in animals:
- Gastrointestinal Issues – Ingesting parts of the robinia tree can cause vomiting, diarrhea, and colic in animals.
- Respiratory Distress – Inhalation of the pollen or dust from the robinia tree can cause respiratory issues in animals, including wheezing and difficulty breathing.

What parts of the robinia tree are toxic
The robinia tree, also known as the black locust tree, is a fast-growing deciduous tree that produces showy, fragrant white flowers in the spring. While this tree is commonly used for landscaping and as a source of hardwood lumber, it is important to be aware that certain parts of the tree are toxic to humans and animals.
- Leaves: The leaves of the robinia tree contain the toxic chemical, robin, which can cause mild to severe poisoning in humans and animals if ingested. Symptoms may include nausea, vomiting, diarrhea, abdominal pain, and fever. In some cases, consuming large amounts of robinia leaves can lead to respiratory arrest or kidney failure.
- Bark: The bark of the robinia tree also contains robin and can cause similar symptoms to those caused by ingesting the leaves. However, the bark is less commonly ingested by humans or animals, as it is tougher and less palatable than the leaves.
- Seeds: The robinia tree produces large, brown seed pods that contain toxic alkaloids. Ingestion of the seeds can cause gastrointestinal symptoms such as nausea, vomiting, and diarrhea. Severe poisoning can lead to convulsions and coma.
- Flowers: While the flowers of the robinia tree are not toxic, they can cause allergic reactions in some people. Symptoms may include skin irritation, itching, and respiratory symptoms such as coughing and wheezing.

If you suspect that you or someone you know has ingested any part of the robinia tree, seek medical attention immediately. It is important to note that while the tree is toxic, it is rarely fatal and most cases of poisoning can be treated with supportive care.
| Toxic Part | Toxic Chemical | Symptoms of Poisoning |
|---|---|---|
| Leaves | Robin | nausea, vomiting, diarrhea, abdominal pain, fever, respiratory arrest, kidney failure |
| Bark | Robin | nausea, vomiting, diarrhea, abdominal pain, fever, respiratory arrest, kidney failure |
| Seeds | Toxic alkaloids | nausea, vomiting, diarrhea, convulsions, coma |
| Flowers | N/A | skin irritation, itching, coughing, wheezing |

Familiarization with Other Toxic Trees and Plants
While Robinia trees are known for their toxicity, there are a number of other trees and plants that also contain poisonous elements. It’s important to be familiar with these toxic trees and plants, especially if you have pets or young children who might consume them.
- Poison Ivy, Poison Oak, and Poison Sumac: These plants are known for causing an itchy, red rash when they come in contact with skin. The rash is caused by an oil called urushiol, which is present in all three plants. You should always wear gloves and protective clothing if you’re going to be removing these plants from your yard.
- Yew: This evergreen tree is toxic to both humans and animals. The entire tree, including the foliage, bark, and seeds, contains a deadly toxin called taxine. It’s important to keep yew trees away from areas where pets or children might play.
- Castor Bean: The castor bean plant contains ricin, a deadly toxin that can cause severe illness or death. While the toxin is present in all parts of the plant, it’s most concentrated in the seeds. You should never attempt to extract oil from castor beans, as this can release the toxin.
In addition to these plants, there are a number of trees that are also toxic:
Table:
| Tree | Part(s) of Tree That Are Toxic |
|---|---|
| Black Locust | Bark, leaves, seeds |
| Horse Chestnut | Seeds, bark, leaves |
| Cherry Tree | Wilting leaves and pits |
| Red Maple | Leaves |
| English Yew | Foliage, seeds, bark |
If you have any of these trees or plants in your yard, it’s important to keep an eye on pets and children to ensure that they don’t come into contact with them. If you suspect that your pet or child has ingested any part of a toxic plant, seek medical attention immediately.
