Where are the chemical poisons concentrated in the Black Locust tree, *Robinia pseudoacacia*?
Answer
The bark, leaves, seeds, and seed pods
The inherent toxicity of the Black Locust plant is localized in specific structures, primarily the bark, leaves, seeds, and the seed pods. Ingestion of these parts is what leads to significant systemic illness, potentially causing symptoms such as nausea, vomiting, diarrhea, weakness, and depression. While the plant is indeed poisonous, the text specifies that the thorn itself, which is a hardened outgrowth, is not generally considered the source of chemical poisons when it merely pricks the skin. The danger associated with a thorn penetration event shifts away from systemic poisoning and toward physical injury, such as trauma or secondary microbial introduction.
