In autumn, seeds drop to the earth and lie still. Similarly, we prepare to hibernate for the winter by drawing inward and consolidating our energy. Traditional Chinese Medicine’s Metal element is associated with autumn. Metal governs the Lung and Large Intestine meridians, with their functions of inspiration and excretion, appropriate storage and release.

The twelve organ systems of Traditional Chinese Medicine (TCM) connect with their western biomedical counterparts, but aren’t limited to western understandings of locations or functions. In TCM, each organ system includes not only the organ’s location, but also primary meridian lines, collateral lines, sinew channels, and more. The Five Elements of Chinese medicine—Water, Wood, Fire, Earth, and Metal—and their associated seasonal changes correlate with these organ systems.

In spring, buds burst with potential energy, flowers push up from under the snow, and, according to Chinese medicine, the Wind blows change, energy, and wellness disturbances hither and thither. Spring is associated with the Wood element, in its upward, outward expansion and infinite possibilities.
