Nature is a very important resource for not only new drug discovery but also application of traditional medicines. Kampo (Japanese traditional) medicines have been used as the traditional formula in which multi-active ingredients may attack multiple target sites to recover complicated symptoms caused by disturbance of the body systems such as immune, neural and endocrine systems. Therefore, their multilateral actions are suitable to treat multifactorial diseases. Kampo medicines are using for the treatment depending on the patient’s clinical situation, either separately or to complement modern western medicine in Japan. Present review describes the concept and characterization of Kampo medicines, and introduces our pharmacological studies of Kampo medicines to clarify their action mechanism and active ingredients. The results may contribute for more evidence-based clinical applications of Kampo medicines.
