Functions of the Spleen
The Spleen holds the Blood in the vessels.
Commentary: The Spleen Yang holds the Blood in the vessels. Impairment of the Spleen's function of managing the Blood results in abnormal bleeding. For example, blood in the stool, blood in the urine, or abnormal uterine bleeding. Another reason for abnormal bleedings is Heat in the Blood; the reckless movement of Heat drives the Blood out of the vessels.
