Objective : In this study, we investigated the effects of Hwangryunhaedoktang Herbal-acupuncture(HHT) at a acupoint, $G_{21}$(Kyonjong) on the Heart Rate Variability(HRV) in adults, as well as we tried to observe how HHT affects on the balance of the autonomic nervous system. Methods : The subject were comprised of 20 healthy adults, who didn't take any drugs which affected on the autonomic nervous system and had normal sinus rhythm in electrocardiogram. The control group was comprised of 9 subjects, who were injected normal saline at $G_{21}$(Kyonjong). The experiment group consisted of 10 subjects, who were injected HHT at $G_{21}$(Kyonjong). We measured HRV by CANS 3000 on three times : before, immediately after, and 20 minutes after injection. The SPSS 10.0 for windows was used to analyze the date and the Wilcoxon signed rank test (in group) and Mann-Whitney U-test(between two groups) were used to verify the results. Results : The following results were obtained ; 1. In each group, Mean-HRV and Mean-RR showed a significant change during 20 minutes after injection. But there were no significant difference between two groups(p>0.05). 2. In experiment group, 20 minutes after injection, norm LF and LHR showed a significant decrease and norm HF showed a significant increase. There were significant difference between two groups(p<0.05). Conclusions : The findings suggest that HHT at $G_{21}$(Kyonjong) in adults relatively activate parasympathetic nervous system and inactivate sympathetic nervous system.
