Heart rules blood and head
In addition to generating qi, in Traditional Chinese Medicine, food also helps create blood. The heart is thought to regulate the blood, control the blood vessels and blood circulation throughout the body.
The Chinese considered that a person’s complexion might indicate the status of the heart. The heart may sometimes affects the mind. For example, a pale person may be deficient in blood including various nutrients, may have suffered too much blood loss, could have a physical health issue and or maybe had one or more significant shocks or upsets.
Speech, a sense of taste, the tongue and the amount of sweating may be affected.
So, according to ancient Traditional Chinese Medicine, the heart rules the blood and head!
