Brief Summary:
The purpose of this study is to determine effect of Mouthwash containing Camellia sinensis extracts on oral malodor and gingival inflammation in gingivitis subjects.

Condition or disease Intervention/treatment Phase
Gingivitis Halitosis Drug: Camellia sinensis mouthwash Drug: Placebo mouthwash Phase 2

Detailed Description:
At baseline, level of volatile sulfur compounds (VSC) in mouth air, Plaque Index and Papillary Bleeding Index will be recorded. Gingivitis subjects will be asked to rinse with Camellia sinensis mouthwash or placebo mouthwash. VSC level will be measured at 30 minutes and 3 hours post-rinsing. For the following 4 weeks, subjects will be rinsed with the assigned mouthwash twice daily after toothbrushing. All parameter will be recorded again at Day 28.
