    Toxic Components Of Wisteria

    Beneath its charming exterior lies a hidden truth – wisteria contains certain toxic components that demand caution and awareness [1].

    Wisteria pods and seeds contain lectins and wisterin which are toxic proteins that can lead to gastrointestinal distress if consumed in substantial amounts. Symptoms include nausea, vomiting, abdominal pain, and, in severe cases, dehydration or even organ damage. It is crucial to keep wisteria seeds and pods away from children, as they may be more susceptible to adverse effects [2].

    Floral Fragrance

    While not particularly toxic, the fragrance emitted by wisteria flowers can trigger respiratory allergies and asthma symptoms in some individuals. People with pre-existing respiratory conditions should exercise caution while being in proximity to a blooming wisteria plant [3, 4].
