Nara Clan Medical Encyclopaedia

This is a huge Medical Encyclopaedia kept by the Nara clan. The members of this clan are apparently skilled in the field of medicine and as such have created and maintained an encyclopaedia of sorts with medical herbs, preparations and the effects of such items as the closely affiliated, Akimichi clan's Three Coloured Pills. This book was instrumental in saving Chōji Akimichi's life after he ingested the last of the pills during his battle with Jirōbō.
