Physiological parameters were recorded and assessment of behaviour was carried out with North Carolina Behaviour Rating Scale. Results: Student’s t-test showed a significant reduction in pulse rate(p=0.049) and respiratory rate(p=0.003) in experimental group. Conclusion: The positive effects of lavender oil on anxiety in children can be performed to reduce anxiety in children as appropriate.
