Toxicity
Symptoms
Severe painful allergic reactions can occur between 12 hours and 7 days after contact. These reactions include severe dermatitis that begins with a rash, redness, itching and blisters where skin has made contact with the tree. Localised swelling of the face, arms and legs is often associated with the rash. All of these symptoms usually last 7 to 10 days. However, chronic sufferers or more sensitive individuals may experience more extreme symptoms over a longer period of time. Contact with any part of the tree can cause these symptoms, but it is the sap that can cause the most severe reaction. Sensitivity to this plant can have an cumulative effect over a number of years, with initial exposure not necessarily causing a significant reaction. However, subsequent contact will result in stronger allergic reactions.
