Intestinal aggregation

Also blood arrow. A disease characterized by the spurting of blood from the anus, described in The Gateway to Medicine (医学入门 yī xué rù mén) as enduring food diarrhea stemming originally from wind damage invasion of the stomach and allowing damp toxin to form an aggregation and to pour into the large intestine to contend with the lesser yīn (shào yīn), giving rise to what is called intestinal aggregation, known popularly as blood arrow because of the forceful issue of blood like an arrow that shoots far.
