Co-citation network of journals with original and review articles on aromatherapy published between 1995 and 2014 that received at least 50 co-citations. Five clusters were identified: cluster 1 (blue, top left), cluster 2 (red, middle left), cluster 3 (green, bottom middle), cluster 4 (purple, right), and cluster 5 (yellow, inset). The inset (bottom left corner) shows the full co-citation network map with two journals (Journal of Chemical Ecology and Florida Entomologist). Clusters located close to each other in the figure indicate related topics
