Effect of Jeongkicheonhyangtang and Kamijeongkicheonhyangtang have been experimentally studied. The results have been obtained as follows : 1. It is proved that analgecic effect on sample I group and sample II group are clearly decreased than control group. Thus, the statistically significant decrease is p<0.005. 2. It is proved that anti-inflammatory effect on sample I group and sample II group are decreased compare to control group. Thus, the statistically significant decrease of sample I group is p<0.05 in 30 and 60-minute, p<0.01 in 90-minute, and p<0.005 in 120 and 180-minute. And those of sample ll group is p<0.05 in 30 and 60-minute and p<0.005 in 90, 120 and 180-minute. 3. It is proved that appearance of gastric ulcer is decreased compare to the control group and the statistically significant decrease is p<0.05. 4. It is proved that plasma epinephrine contents of sample I and II group are clearly decreased compare to the Control Group and the statistically significant decrease is p<0.005. 5. It is proved that plasma norepinephrine contents of sample I group is drastically decreased compare to the control group and the statistically significant decrease is p<0.005. 6. It is proved that plasma dopamine contents of sample I and II group are decreased than the contort group and statistically significant decrease of the sample I group is p<0.005, and those of the sample II group is p<0.05. As the above mentioned results of experiment, It is belived that Jeongklcheonhyang and Kamijeongkicheonhyang have effect for stress.
