Doctors who learned exclusively western medicine probably understand a priori Kampo (Japanese herbal) medicine merely as a kind of folk medicine which is not so effective and only a supplementary therapy to western medicine. We have been performing experiments on the mechanism of epileptogenesis mainly at the cellular level for a long time. During the research process, we unexpectedly encountered Kampo (Japanese herbal) medicine, and also performed research on the mechanism of action of a herbal mixture prescription, saiko-keishi-to-ka-shakuyaku (SK, TJ-960). Recently we discovered that SK acts to induce the best functional state of neurons and consequently intractable nervous symptoms disappear. SK has protective effects against neuron damage, normalizing effects on developmental defects of El mouse neurons, complete preventive effects on stress-induced increased c-fos and HSP 72 expression, complete suppression effects on the Reilly syndrome, complete normalizing effects on expression of the seizure-related gene, PTZ-17, and also, surprisingly, complete suppression effects on amyloid β protein-induced neuron death. Such wide ranging effects which are preferable to functional maintenance and development of neurons can not be obtained by pure chemical drugs. These findings suggest that we should effectively use such ancient herbal prescriptions which show excellent preventive effects against neuron damage, enforcing action on natural healing forces and even regulatory action against adverse expression of genes, at least to prevent intractable nervous diseases, such as epilepsy, Alzheimer's disease and developmental defects of neurons during pregnancy and after birth. We should also create a future medicine, the ‘third medicine’, which is situated in a higher dimension than that of contemporary oriental and western medicines. For this purpose, it is necessary to perform research on the mechanism of action of Kampo (Japanese herbal) medicine. |
