In accordance to medical practices at that time, there were physicians in charge of 'hondo,' or internal medicine, and others called 'zakka' covering all other areas of medical care including surgery, ophthalmology, dentistry, acupuncture and moxibustion.
当時の医学の慣例に倣って「本道」と呼ばれた内科を担当する医師と外科をはじめ眼科・歯科・鍼灸などを一括した「雑科」に分けられていた。
