What Are the Symptoms of Willow Catkin Allergy?

Willow catkin allergy refers to contact dermatitis or allergic dermatitis triggered in some individuals upon skin exposure to willow catkins. Typical manifestations include itching and redness or swelling of the skin. In other cases, inhalation of willow catkins through the nasal passages may provoke coughing, asthma, or allergic rhinitis. Upon onset of allergy, initial protective measures—such as wearing masks and hats to avoid further exposure—are essential. Additionally, symptom-based treatment is required depending on whether the reaction involves the skin or respiratory tract; antihistamines or other anti-allergic medications may be used. Seek immediate medical attention if severe symptoms such as asthma attacks or breathing difficulties occur.

This season marks the peak period of willow catkin dispersal—and also a high-incidence period for diseases and allergic reactions. Willow catkin allergies primarily affect the upper respiratory tract: airborne catkins enter the respiratory system via inhalation, causing discomfort. Once inhaled, willow catkins can cause significant distress, commonly manifesting as coughing, runny nose, sneezing, or asthma.

If symptoms of willow catkin allergy occur—especially those involving respiratory distress—prompt medical evaluation is crucial to prevent airway edema or obstruction.
