Carrying or conveying laxative or excretory properties; relating to substances that promote evacuation.
From eccoprotic (mildly laxative) + Greek '-phoros' (carrying, bearing). This highly specialized medical term combines the root for mild purgation with the Greek suffix meaning 'that carries or brings.'
This is basically the definition of an ultra-specific medical jargon word that doctors probably used once in a medical treatise and then abandoned—it's technically correct but so cumbersome that it died out almost immediately.
