 "Reading of Materia Medica" states: "Magnolia bark has a thick smell and is used to descend. When descending, it is warm and specializes in dispersing. It is bitter and specializes in purging. Therefore, it is used to treat solid diseases. Stroke has obstructed bowel movements, typhoid fever has mild wheezing, abdominal distension after sweating, whipping stool, and headache with turbid qi rushing up. All of these are suitable for Magnolia bark. As for warmth, it can dissipate cold, and bitterness can purge heat. It can dissipate and purge, so it can relieve the shock and palpitation caused by qi reversal. It can disperse qi and purge blood, so it can treat qi and blood stasis and dead muscles. It is not clear in the Classics that it can relieve distension and purge qi. Zhongjing used it because of its bitter and warm smell, and got the meaning behind the Classics."
