Research theme





Outline of the research

Natural resources of herbal drugs are gradually decreasing in many countries due to environmental degradation resulted from global warming and human made catastrophes. Diversity is the key to sustain environment including natural resources. For herbal drugs and the formulations, however, the safety and efficacy must be secured. Therefore, it is necessary to standardize the herbal drugs through limiting the acceptable range of diversity in quality. Aiming for standardizing herbal drugs and developing the methods for sustainable use of medicinal resources, I engage in the following subjects.

1. Field investigation on herbal drug resources around Asian countries and analysis on diversity of the medicinal plants from genetic, chemical and pharmacological aspects.
2. Quality evaluation of medicinal plants aiming for selecting proper species for cultivation and expanding domestic cultivation.
3. Standardization of herbal drugs based on genetic polymorphisms and chemical constituents.
4. Expanding of the database by accumulation of information on traditional medicines.

Thoughts on research

Quality of herbal drugs with multiple components varies depending on genetic and environmental factors. My theme is to stabilize the quality for providing the inherent effects of herbal drugs based on scientific evidences, including genetic, chemical and pharmacological data. Moreover, the studies to select value-added plants and to establish a cultivation method including post-harvest processing method have been conducted toward the development of branded herbal drugs.
