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.
