Many of these persons, who often suffer from depression or dizziness, take medicines, either prescribed by a physician or on their own, if they recognize their problem themselves. AOZORA, an organization in Fukui Prefecture that supports such persons and encourages them to communicate with and adapt gradually to their local society, has observed that several kinds of herbal tea improved patients’ morbid conditions. Mentha sp. (mint) leaves, Chrysanthemum sp. flowers, Coix lacryma-jobi (adlay) fruits and seeds, Houttynia cordata leaves, Geranium thunbergii leaves, Eucommia ulmoides bark and leaves have been given to reduce dyssomnia and dizziness in patients. To help assess the relationship between herbal tea consumption and its benefits, we gathered patients’ experiences on the Internet and developed a system that should be helpful for gathering together such knowledge for the benefit of both patients and supporters and of keeping track of patients’ conditions. Analysis of such collected experiences by data mining may lead to new knowledge. We also report the results of using this system in this way.
