Intervention in oxidant pollutant exposure-induced inflammation at 18 hrs by topical application of the oil preparation. Individual data showing the upper respiratory inflammatory responses of subjects exposed to ozone (0.25 ppm, 2 hr) when pretreated with 50 μl of scented sterile water (sham) or a mixture of natural oils administered by aerosol spray to each nostril. Each subject is represented by the same symbol in both arms of the study; numbers correspond to subject numbers in Table 1. Points connected by dashed lines represent means of each group. * indicates significant difference from baseline (P < 0.05) by paired t analysis.
