What can be said about the transformation of Qi and blood?

The idea that essence transforms into blood from the same source reflects a fundamental concept in Traditional Chinese Medicine (TCM). In this context, essence (jing) is considered the foundational material that supports various physiological processes, including the generation of blood. This transformation highlights the interconnectedness of different substances in the body.

Essence is derived from food and is transformed into the vital substances Qi and blood, indicating that both Qi and blood are ultimately nourished by the same essential substances, supporting the notion of their interdependence in maintaining health. This process underscores the holistic view of bodily functions within TCM—everything is interrelated, and the transformation of one vital aspect influences others.

Additionally, while Qi is critical to the circulation and function of blood, the statement acknowledges the role of essence as a precursor to blood production, emphasizing its importance in this transformation.

This recognition of the role of essence helps explain various clinical presentations and treatment strategies in TCM, where nourishing essence can be a therapeutic goal to support the production of blood.
