Zong Qi (Pectoral Qi)

Zong Qi (Pectoral Qi) is a type of qi in the body. It is produced after birth and is therefore regarded as an acquired essential qi.

The Spleen moves Gu Qi (from food essence) up to the Lung combining it with Qing Qi (Clear Qi) from the air. Accumulating in the chest, Pectoral Qi is produced. Due to its convergence in the chest, Pectoral Qi is sometimes referred to as the ‘Sea of Qi’. It is sometimes also called ‘Gathering Qi’.

When transported from the chest, it is divided into Ying Qi (Nutrient Qi) and Wei Qi (Defensive Qi), which are then distributed to the rest of the body.

There are two major functions of Zong Qi:

  1. Warming and nourishing the Heart vessels to maintain circulation of qi and blood.
  2. Warming and nourishing the Lung in order to maintain good respiratory and speaking functions.

If the Pectoral Qi is deficient or weak, the extremities (hands and feet) can become cold and weak. As Pectoral Qi gathers in the throat, if it is weak, the voice may also become weak.

Emotional disturbance, particularly grief, can affect the Lung, thereby weakening the Pectoral Qi. This cause the qi to disperse, thus reducing the function of Pectoral Qi.
