TCM Philosophy: Yin-Yang and Five Elements

The philosophical system of traditional Chinese medicine — based on the concepts of yin-yang (阴阳) and the Five Elements (五行) — provides the theoretical framework for understanding health and disease in TCM. These concepts, developed over two thousand years, offer a distinct approach to understanding the body, illness, and treatment.

Yin and Yang

Yin and yang describe complementary opposites: cold/hot, interior/exterior, water/fire, stillness/movement. In the body, yin is the material basis — blood, fluids, organs; yang is the functional activity — circulation, metabolism, warmth. Health is a dynamic balance between yin and yang; disease is an imbalance.

The Five Elements

The Five Elements — wood, fire, earth, metal, water — describe the relationships between organs, tissues, emotions, and environmental factors. Each element is associated with organs (wood with liver/gallbladder, fire with heart/small intestine, etc.), emotions (anger, joy, worry, grief, fear), seasons, colors, and flavors. Treatment aims to restore harmony among the elements.
