Which organ transforms food Qi into blood?

The organ primarily responsible for transforming food Qi into blood is the spleen. In Traditional Chinese Medicine (TCM), the spleen is crucial in the process of digestion and in the transformation of food into Qi (which is vital energy). This vital Qi is further transformed into blood, emphasizing the foundational role of the spleen in nourishing the body and maintaining health.

While the heart plays an important role in circulating blood and is often associated with the quality and vitality of blood, it does not transform food Qi into blood. The kidneys are involved in storing essence and play a role in reproductive health and overall vitality but are not the primary organ for this transformation either. Additionally, while the liver is responsible for the regulation of Qi and the storage of blood, it acts more as a facilitator for blood circulation rather than as the primary transformer of food Qi into blood.

Thus, the spleen is key in this process, and recognizing its function helps in understanding the interconnectedness of various organs in TCM and their roles in maintaining health.
