Animals parameter design was conducted to prove the validity on the mixing ratios of herbal medicines which consists of multiple kinds of herbs. Mixing ratios were assigned to an orthogonal array. The variability of drug and its efficacy were evaluated by SN ratio and sensitivity, respectively. Comparison was made between current and optimum conditions. The individual difference in the seriousness of sickness between animals was considered as the noise factor. Variability was controlled by the use of SN ratio, As a result, the mixing ratio under the optimum condition was extremely effective compared with the worst among the 18 mixing conditions. It was also confirmed that the efficacy of the mixing ratio reported in the literatures bears comparison with the optimum one.
