So we can see, that the essence of the word Qi relates to the vital energy that flows through us and animates us and is inherent in every living thing.
The character Qi has many meanings in Chinese based on it’s use in different contexts. For example, it can mean defensive energy (eg: adopting a protective, immunological role) or nutritive energy (that assists growth and repair ) and so on. It is also used to describe the energetic qualities of the climate/weather. This is how Chinese medicine practitioners begin to make the link with various seasonal and climatic effects on the body. For example, it’s not uncommon for people to complain their arthritis is worse in damp weather, or their asthma is worse for breathing in cold air and so on.
The Meridian System
The meridian system is a network of discreet pathways that carry the Qi and cover the entire body and access every part of it. While this occurs at the superficial level (the skin and hair) it also occurs at the deepest level (bones and marrow). During their acupuncture treatment, people sometimes comment that they can feel a sensation along a specific line of their body, which relates to one or more meridians.
