This double-blind randomized clinical trial was performed to evaluate the anti-anxiety, anti-stress effect of a modified formula WS-01 consisted with several herbs(Jujubae Fructus. Longanae Arillus. Poria Cocos) and germinated rice. The extract of the formula was administered (p.o) to 24 students and placebo was to 23 students for 4 weeks. STAI-KYZ(Hahn. Hakjisa), ABR2000(Meridian, Korea), CBC, LFT, U/A were checked before and after the administration period. There was no difference between the STAI score of WS-01 and that of placebo group in first test. But the STAI state anxiety score was 5.33±7.33 reduced in WS-01 group and it was 0.52±6.42 increased in placebo group in second test. this result was significant stastically. 10 students in WS-01 group showed improving result, but only 1 student in placebo group showed improving result of ABR2000 test. The result of ABR2000 was analyzed with curve 2, Regulation 2, and graph 1,2,3, because those reflect central nerve system and stressful condition of the body. There was no significant result in first and second CBC, LFT, Urine test. The results of this clinical study suggest that WS-01 has anti-anxiety, anti-stress effect, and it could be applied to various conditions or disorders related with anxiety and stress.
