Acupuncture Meridians: Large Intestine

In Traditional Chinese Medicine, meridians are paths through which the life energy ‘qi’ and blood flows, connecting acupuncture points across the body. Within the system there are 12 principal meridians which are divided into groups of yin and yang and pertain to interior organs as well as extending all over the surface of the body’s exterior, creating a network that links tissue and organs. It is a network which helps to maintain balance in the mind and body.

Each meridian has an external point along its pathway which has all the acupoints and an internal counterpart which connects to its pertaining organ. These meridians are spread bilaterally along the length of the body with the Yin meridians of the arm being the Lung, Heart, and Pericardium and the Yang meridians of the arm being the Large Intestine, Small Intestine, and Triple Burner. The Yin Meridians of the leg are the Spleen, Kidney, and Liver and the Yang meridians of the leg are Stomach, Bladder, and Gall Bladder.

Each meridian has a multitude of acupoints located in different areas of the body which is why in this series we will be systematically moving through each, detailing where the correlating acupoints are located and looking at how exactly they can help to balance the body.

In this piece we will be focusing on the large intestine acupuncture meridian, exploring all of its 20 acupuncture points and how they can help various ailments.
