Research using the MT method to study foot-bath effect has shown Kampo bath salts to be highly effective. They are, however, expensive because of their use of herbal medicines. In this study, the herbal composition ratio was varied and it was found that there exists a composition ratio with lower cost but greater effect. States thought from everyday experience to represent conditions of low fatigue were taken as the unit space, and states distanced in the MT system by intentionally adding fatigue were taken as the signal space. The study covered physical condition, lifestyle, and Kampo questionnaire data. The effect of bath salts was optimized from the degree to which foot baths reduced the distance of the signal space, by studying the sensitivity β and the S/N ratio of the reciprocal of the error variance. Enlarging on these results, it appears possible to use the MT system to evaluate drug effect and find appropriate prices.
