The aim of this review is to recognize the ability of plants used as food and medicine for our health care. From this point of view, we have studied economical production techniques of medicinal plants and vegetables that have physiological functions such as disease prevention, health maintenance and improvement of physical function. We revealed the suitable cultivation techniques such as the long-term freezing seed storage, and systematic and efficient seedling production of Swertia japonica in the future domestication in Japan. We have also studied the development of a new and friendly product for preparing decoction of Kampo medicine (Japanese traditional medicine) to utilize medicinal plants effectively. It was possible that the decoction of some Kampo medicines in a micro-wavable container could be carried out in substitution for a common method. This study revealed that the improvement of decoction method of Kampo medicine might contribute to conserve the energic or natural resources, especially medicinal plants of crude drugs in comparison with the conventional way. Moreover, the reevaluation of some vegetables such as Japanese radish and carrot in terms of the suitability as materials for “Yakuzen”, and creating and producing of newly low potassium tomatoes for improving the quality of life (QOL) of dialysis patients and potassium restricted patients were also studied by focusing traditional and local vegetables. Some local cultivars containing stronger flavor and taste with higher amount of functional constituents are suitable for our health care than F1 (first filial generation) cultivars. Our research will give feedback each other by cross cutting way, and human health science from the cultivation to utilization of medicinal plants and vegetables will be important and needed for our healthy and comfortable life in the future.
