What is considered the source of life in Chinese medicine?

In Chinese medicine, the concept that is often regarded as the source of life is Ch'i, often spelled as Qi. Ch'i represents the vital life force or energy that flows through all living things. It is fundamental to maintaining health and balance within the body. Without a proper flow and balance of Ch'i, individuals may experience health issues or disease.

Blood is indeed essential for life and plays a critical role in nourishment and vitality within the body. However, it is considered one of the components of Ch'i and does not encompass the entirety of life’s energy as described by the concept of Ch'i.

Qi Gong refers to a Chinese practice aimed at cultivating and balancing Ch'i through movement, meditation, and controlled breathing. While it is related to health and well-being, it does not represent the source of life itself.

Yin and Yang are fundamental concepts in Chinese philosophy that represent dualities and the nature of balance in the universe. They are essential in understanding health and disease within Chinese medicine but serve as a framework for interpreting changes in Ch'i rather than as the source of life.

Thus, Ch'i stands out as the accurate answer, highlighting its significance as the foundational energy believed to sustain life.
