Clinical Studies:

Demodex folliculorum (Follicular or Demodicid mite) is a zoonotic obligatory parasite with clinical manifestations range from normal infestation to complicated ones. 

Treatment of human facial demodicidosis with freshly prepared camphor oil with or without glycerol dilutions gave complete cure with concentrations of 100%, 75%. and 50%. Incomplete cure but marked drop in infestation density was achieved with diluted camphor oil at concentrations of 25-20%. 

Camphor oil application proved to be safe with no side effects.

Eucalyptus extracts were found to possess an antibacterial activity against some oral pathogens that produce oral malodor compounds in vitro, however, the clinical effects with respect to oral malodor in humans remain unproven.

In the present investigation, a randomized clinical study was designed to test the hypothesis that eucalyptus-extract chewing gum can reduce oral malodor in the general adult population.

Subjects were randomly assigned to the following three groups: a high-concentration (0.6% eucalyptus extract) group, a low-concentration (0.4% eucalyptus extract) group, and a placebo group. The intake period was 12 weeks. 

The organoleptic score, level of volatile sulfur compounds (VSCs), and tongue-coating score were recorded at baseline and 4, 8, 12, and 14 weeks. 

Relative to baseline readings, significant reductions in clinical parameters, including organoleptic and tongue-coating scores in the high- and/or low-concentration groups, occurred at 4, 8, 12, and 14 weeks.

In addition, group-time interactions revealed significant reductions in the organoleptic score, VSCs, and tongue-coating score in both concentration groups compared to the placebo group.

Eucalyptus-extract chewing gum had long-term effects on the olganoleptic score, levels of VSCs, and tongue-coating score. These findings suggest that eucalyptus-extract chewing gum may reduce oral malodor by decreasing the accumulation of tongue coating.
