Meridians and Acupoints: How Energy Flows in the Body According to Huangdi Neijing
mars wuIntroduction: What Are Meridians and Acupoints?
In Traditional Chinese Medicine (TCM), the concept of meridians and acupoints is crucial to understanding how Qi (the body's vital energy) flows through the body. This understanding is largely derived from Huangdi Neijing, an ancient text that remains the cornerstone of TCM. Huangdi Neijing provides a detailed map of the human body, highlighting how energy moves through pathways, often referred to as meridians, and how specific locations on the body, acupoints, can influence the flow of Qi.
The balance and smooth flow of Qi are essential to maintaining good health, and meridians play a vital role in regulating the body’s energy. When the flow of Qi is disrupted, illness and disease can result. Understanding how meridians and acupoints work together to promote health is key to achieving balance in both body and mind.
What Are Meridians?
Meridians are channels or pathways through which Qi flows in the body. There are 12 primary meridians in the human body, each corresponding to a specific organ or system. These meridians form an intricate network that connects the body’s organs to each other, creating a holistic system where energy circulates, nourishes, and maintains health.

Each of the 12 primary meridians is linked to a specific organ, such as:
- Lung Meridian (responsible for respiratory health)
- Stomach Meridian (related to digestion)
- Heart Meridian (regulates emotional health and circulation)
In addition to these 12, there are also 8 extraordinary meridians, which store and distribute Qi to the primary channels as needed. The flow of Qi through these meridians is akin to blood circulating through blood vessels. When the meridians are clear, Qi flows smoothly, nourishing the organs and tissues, ensuring optimal health.
What Are Acupoints?
Acupoints are specific locations on the body where Qi is concentrated or where it can be accessed directly through the skin. These points are found along the meridians, and stimulating them with techniques such as acupuncture, acupressure, or moxibustion can help to restore balance and regulate the flow of energy.
In Huangdi Neijing, acupoints are seen as gateways to the body’s energy system. Needles or pressure applied to these points can unblock stagnation, enhance energy flow, and release emotional or physical blockages that cause illness. The strategic stimulation of acupoints can target specific ailments, whether they be physical pain, digestive issues, or emotional distress.
For example, the ST36 acupoint, located below the knee, is widely known for its ability to strengthen the immune system, boost energy, and improve digestive health.
How Do Meridians and Acupoints Work Together?
In Huangdi Neijing, the interaction between meridians and acupoints is central to TCM healing practices. When Qi is blocked or stagnant, it leads to various health issues. Stimulating specific acupoints helps to clear blockages, restore Qi flow, and rejuvenate the body's natural healing processes.
This is why acupuncture, moxibustion, and acupressure are so effective in treating a wide range of conditions. They target acupoints along meridians to harmonize the body’s energy system and restore balance.
The Role of Qi in Health According to Huangdi Neijing
According to Huangdi Neijing, the smooth flow of Qi is vital for maintaining health. When Qi is flowing freely through the meridians, the body remains balanced, energetic, and resilient to disease. However, Qi blockages can lead to illness.
Here are some examples of how Qi imbalances affect health:
- Stagnant Qi: Can result in pain, tightness, or discomfort (such as muscle stiffness or headaches).
- Deficient Qi: Can lead to fatigue, weakened immune system, and overall depletion of vitality.
- Excessive Qi: Can lead to symptoms like restlessness, anxiety, or high blood pressure.
By stimulating acupoints along the meridians, acupuncture and moxibustion help to regulate Qi, promote its smooth flow, and restore balance to the body.
Benefits of Understanding Meridians and Acupoints
Understanding meridians and acupoints helps you understand how Traditional Chinese Medicine works as a holistic healing system. Here’s why this knowledge is powerful for modern health:
- Improves circulation and energy flow: By stimulating the right acupoints, you can promote the free flow of Qi and enhance circulation throughout the body.
- Balances the body's systems: TCM sees the body as a connected system. Working with meridians allows for a deeper understanding of the body’s interconnectedness.
- Addresses both physical and emotional health: Meridians not only affect physical health but also the emotional and spiritual well-being. Acupuncture and acupressure can relieve stress, anxiety, and emotional blockages.
- Prevents disease: By keeping the energy channels clear and balanced, you help prevent illness before it starts, as advocated in Huangdi Neijing.
How to Restore Balance Using Meridians and Acupoints
Here are a few ways you can start restoring balance in your body using TCM principles:
- Acupuncture: This involves the insertion of fine needles into acupoints to stimulate energy flow and unblock stagnant Qi.
- Acupressure: This technique uses manual pressure on specific acupoints along the meridians to achieve the same effect as acupuncture.
- Moxibustion: A technique where moxa (a form of mugwort) is burned near specific acupoints to warm the body and stimulate Qi.
- Herbal Remedies: Herbs that target specific meridians and acupoints can help restore balance and regulate Qi.
