Objectives: The aim of this study was to investigate deodorizing effectsof medicinal herbs (Mume Fructus, Eriobotryae Folium, Acanthopanacis Cortex, Angelicae Dahuricae Radix) for development of a gargle solution.
Methods: 1. The antimicrobial effects of medicinal herbs were evaluated with the minimal bactericidal concentration (MBC) and the change of the number of viable cells in the herb extracts(1%) for 48 hrs against P. gingivalis 2561 and Pr. intermedia ATCC 25611. 2. Deodorizing activity of each herb and Garglin gainst methyl mercaptan were analyzed by gas chromatography (GC). 3. We used the malodor modeling of the salivary sediment system with a Halimeter. 4. In the preliminary clinical study, the baseline concentration of VSC in the oral cavity of each subject was measured by Halimeter. Subjects would gargle for 30 seconds with cysteine. After 4 minutes subjects would gargle for 30 seconds with Garglin and herb extracts (2%). Subsequently, concentration of VSC were measured at 0, 4, 8, 12 and 20 minutes.
Results: 1. MBC of Mume Fructusfor P. gingivalis 2561 was determined to be <1% and MBCs of Eriobotryae Folium for P. gingivalis 2561 and Pr. intermedia ATCC 25611 were determined to be <2% and <1%, respectively. Mume Fructus (1%) completely suppressed the P. gingivalis cell viability from 5 hrs and Eriobotryae Folium (1%) completely suppressed the Pr. intermedia cell viability from 48 hrs. 2. In GC analysis, deodorizing activities were 91.54% with Mume Fructus, 87.97% with Eriobotryae Folium, 100% with Acanthopanacis Cortex, 72.36% with Angelicae Dahuricae Radix and 40.54% with Garglin . 3. In malodor modeling of the salivary sediment system, each of the medicinal herbs had significantly inhibitory effect on malodor formation (p<0.05). 4. In the preliminary clinical study, the concentration of VSC of the herb groups was significantly lower than of the control group, but not in Garglin .
Conclusions: Mume Fructus, Eriobotryae Folium, Acanthopanacis Cortex and Angelicae Dahuricae Radixhave deodorizing activities and potential as an effective mouthwash against oral malodor.
