In herbal medicine, qi (氣) often refers to thermal nature—how warming or cooling a food or herb feels in the body. Substances are understood along a spectrum from hot and warm to cool, cold, and neutral. These thermal qualities are relatively easy to perceive, influencing whether internal activity speeds up or slows down.

The four seasons illustrate the fundamental movement patterns of qi—rising, expanding, contracting, and descending—each linked to a direction, phase, and zang. This article explores how these seasonal dynamics reflect the interaction of heavenly and earthly qi, forming the foundation for understanding the Five Phases (五行) and the Five Zang “Organs” (五臟) in East Asian Medicine.

The ancient Chinese viewed the seasons not only as divisions of the year but as the living rhythm of yin and yang—the foundation of all things. Through observing sunlight, shadow, and cyclical change, they mapped time itself as a field of movement, revealing the energetic patterns that shape both nature and life.
