What is qi and where did this idea of it come from?
Central to ancient Chinese theory is the thought that we have Qi (vital energy/innate force) that flows throughout our entire body. The ancient Chinese believed that Qi is the substance behind our ability to move and protect ourselves from diseases and pain. It was believed that an individual's health was dependent on the balance, quantity and quality of their Qi.
When Qi moves throughout your body freely, you will reap the benefits of good mental, physical and emotional health. When your Qi is stuck (or "stagnant") then parts of your body is no longer nourished with vital energy, thus dis-ease ensues.
Like I mentioned in Loveland Acupuncture:"How It Works" - your body is just one Great Big highway that wants & needs to flow freely to maintain its harmony.
