Outline of the research
The best medicine is that of treatments of the pre-disease state; this is known as mibyou in traditional Japanese medicine. The concept was first explained in the Yellow Emperor’s Inner Canon, the oldest surviving book on Chinese medicine. Recently, many exceptionally effective but expensive pharmaceuticals, such as antibody drugs and molecular-targeted agents, have been developed, and these contribute our health and welfare. However, the increasing burden of treatments using these drugs will surely lead to medical economic disaster. With this in mind, the goal of my study is to clear the biological mechanisms of the pre-disease state and create new preemptive medicines targeting the pre-disease state. I mainly plan to do this using research techniques related to pharmaceutical science, immunology, pharmacology, and traditional medicine.
Thoughts on research
2000 years has been passed from Yellow Emperor’s Inner Canon.
It’s high time to start developing new preemptive medicine for the pre-disease state, Mibyou!
The development will open the door which connect to novel medical and pharmaceutical science.
I strongly believe that the fusion between Herbal medicine and Food science are key role of the success for novel medical pharmaceutical science.
