The reduction of VOC in artificial saliva. In artificial saliva 16 chemicals were detected (Table 1) using GCMS. Negative numbers represent an increase. The contents of VOC reduction are shown as mean with SD error bars (n = 3). *Means that the contents of the control group continued to increase, while the contents of the treatment group decreased significantly after administration. The p values are, in order, 0.027, 0.042, 0.033, 0.036, 0.034, 0.021, 0.030, 0.027 compared the control with the treatment groups
