Imbalances of Fire Ying in the body
In Chinese medicine the [Pericardium] is not distinguished from the [Heart], except that it is the first line of defence against external pernicious influences attacking the [Heart]. The [Pericardium] is also called the "Heart Cover" or "Heart Governor". It is responsible for the "outer matters", the functionality of the [Heart], regulating [Blood] circulation, heartbeat and heart frequency.
The [Heart] is also an [Organ] of [Fire Yin]. The [Pericardium] is paired with its [Yang Organ], the [Triple Burner], and the [Heart] with the [Small Intestine].
