Objectives : This study aims to assess the effects of incense smokes of 'Cheung-Woon'(consists of several kind of herbal powder) on autonomic nervous system activity and attention in healthy individuals. Methods : A total of 48 healthy volunteers participated in this study. The volunteers were examined with heart rate variability (HRV) before and after incense smokes inhalation of 'Cheung-Woon'. HRV measured the mean RR, mean HR, SDNN, VLF, LF, HF, TP, norm LF, norm HF, and LF/HF ratio. 'Cheung-Woon' consists of 7 herbal powders, known for useful effect on attention. Results : After inhalation smokes of 'Cheung-Woon', the mean RR, and mean HR were decreased and SDNN, VLF, LF, TP were increased, but it's not significant. Further, HF, and norm HF were decreased, and LF/HF ratio, and norm LF was increased significantly (p<0.01). Conclusions : This results (Ed note: 'this result' or 'these results') show that incense smokes inhalation of 'Cheung-Woon' is an effective way of decreasing parasympathetic nervous activity and increasing sympathetic activity and attention.

Objectives : This study aimed to assess the effects of incense smokes of 'Cheung-Woon' on the concentration and EEG in healthy individuals. Methods : A total of 48 healthy volunteers participated in this study. The volunteers were examined with K-MAS, CBT(Corsi block tapping task), and EEG before and after smelling the incense smokes of 'Cheung-Woon'. K-MAS measured the recalled words, and CBT measured the recalled positions and orders of the color boxes. EEG measured the relative power of ${\theta}$ wave, ${\alpha}$ wave, SMR wave, mid-${\beta}$ wave, high-${\beta}$ wave, ${\gamma}$ wave and T(concentraion index T = (SMR wave + mid-${\beta}$ wave) / ${\theta}$ wave). 'Cheung-Woon' consists of 7 herbal powder, known as a useful effect on the concentration and memory. Results : After smelling 'Cheung-Woon', K-MAS were increased significantly(p<0.05). In relative power of ${\theta}$ wave, F4, T3, and P4 were decreased significantly(p<0.05) and P3 was also decreased significantly(p<0.01). In the relative power of ${\alpha}$ wave, SMR wave, and mid-${\beta}$ wave, the values were not significant. In the relative power of high-${\beta}$ wave, Fp1, and P4 were increased significantly(p<0.05). In relative power of ${\gamma}$ wave, T3 were increased significantly (p<0.05). In T value, F4, T3, T4, and P4 were increased significantly(p<0.05) and P3 were also increased significantly(p<0.01). Conclusions : This results show that smelling incense smokes of 'Cheung-Woon' is an effective way of increasing concentration and memory.

The purpose of this study was to assess the effects of herbs aroma on relaxation in highly stressed volunteers with heart rate variability(HRV) and SACL(stress arousal check list). 28 highly stressed volunteers participated in this study. The volunteers were examined with heart rate variability(HRV) and SACL(stress arousal check list) before and after smell herbs aroma. After smelling powder incense composed with oriental medicine herbs, mean RR, SDNN, LF, HF, TP were incresed and mean HRV, LF/HF ratio were decreased, but it was not significant. And VLF, norm HF were incresed and norm LF was decreased significantly. This results show that the powder incense composed with oriental medicine herbs effects on decresing sympathetic nervous activity and increasing parasympathetic activity and rebalancing autonomic nervous system who were under stress.
