*Shenghui Fang*: Hematochezia in infants and children occurs because the Heart governs the blood vessels. When there is heat in the Heart, the heat affects the blood. Blood, upon receiving heat, becomes volatile and flows recklessly, deviating from its normal course. If the blood seeps into the Large Intestine, it causes hematochezia.
*Qianjin Fang* prescription for bleeding after defecation.
