Effects of thyme (TO), cinnamon (CO) and lemongrass (LO) essential oils on (A) breathing frequency, (B) tidal volume, (C) minute ventilation, (D) time of inspiration, (E) time of expiration, (F) peak inspiratory flow, (G) peak expiratory flow, (H) relaxation time and (I) Penh compared to the negative control paraffin oil (PO), after lipopolysaccharide (LPS - black columns)/phosphate-buffered saline (PBS - white columns) treatment. (n = 8–10/group, # p < 0.05, ## p < 0.005, ### p < 0.0005, #### p < 0.0001 vs. respective PBS-treated group, *p < 0.05, ** p < 0.005, *** p < 0.0005, **** p < 0.0001 vs. LPS-PO-treated mice).
