There is no question that the exotic appearance of the acacia makes a good impression. But as beautiful as the deciduous tree may look, it should be treated with caution. Certain parts of plants contain toxins that can be dangerous for other living beings. Read here what the toxic properties of the acacia are all about.
Acacia leaves are poisonous
Poison to protect against predators
The toxicity of the acacia is not particularly high. However, consumption is strongly discouraged. Animals that still dare to injure the deciduous tree as a source of food will learn the meaning of the proverb "One learns from mistakes". The acacia has developed a protective mechanism that protects it from predators. If an animal gnaws on a tree, it produces the scent ethene, which warns neighboring trees of the pest. These then react with the formation of toxic substances, so-called tannins, in the leaves. If the animal moves on and feeds on the remaining trees, it poisons itself with the tannins.
The robinia is particularly poisonous
Much more poisonous than the acacia is a close relative, the black locust, also called false acacia. Here, all parts of the tree are extremely poisonous, except for the blossom. The bark in particular is classified as highly toxic and can even kill animals.
Who is at risk?
- Children (the bark smells sweet and has a sweet taste, resulting in a high risk of temptation)
- Workers and gardeners who inhale the dust when sawing the branches
- Bovine
- horses
- dogs
- cats
- birds
- Small game such as hares and rabbits
The first symptoms are nausea and abdominal cramps. Later, dizziness, fatigue, diarrhea, balance disorders, uncontrollable convulsions or blindness occur. A clear sign are dilated pupils.
