Functions of the Liver
The Liver stores Blood and regulates its volume.
Commentary: The Liver is able to retain Bood and regulate the amount of Blood in the body. The amount of Blood in the various parts of the body varies according to physiological needs. During physical activity, Blood is distributed throughout the body, meeting the increased need for nutrients. When the body is at rest or asleep, Blood flows back to the Liver to be stored. When the Liver's Blood storing function is disturbed, for example in Blood Deficiency, the amount of Blood is reduced and there is not enough Blood in the body to supply all needs. It manifests, for example, as numbness and tingling in the extremities. These sensations are likely to be first noticed at night or when resting, since the amount of Blood is even more reduced during rest and inactivity. Other signs include blurred vision, and vertigo, due to the inability to supply Blood to the brain quickly enough when changing position.
