7 Unique Facets of Classical Chinese organ systems

I’d like to piggyback off of the organ clock post and introduce the Chinese medicine theory of organs in a little more depth.

Why should we pay attention to an alternative way of looking at the body – hasn’t conventional biomedicine (aka Western medicine) figured it all out? There are many ways of categorizing the various structures and functions of the body, some older, some newer. Each system takes different features of the human being to be primary, each system has used their own conceptual understanding to render a viable picture of the body and its interactions. Perhaps most importantly, each system uses their vision of the human being to craft effective treatments. It seems reasonable to expect that different systems will create different spheres of effectiveness – a topic for a future post.

1. There are twelve organ systems in Chinese medicine

Heart, Small Intestine, Bladder, Kidney, Pericardium, Triple Burner, Gall Bladder, Liver, Lung, Large Intestine, Stomach and Spleen. The typical convention is to capitalize when we are talking about Chinese organ systems and not to capitalize when we are referring to the anatomical organ known to Western medicine. Another convention is to refer to the in the singular. So, for instance, the Lung organ system includes the Lungs, but we don’t say – for example – The emotion of the Lungs is grief.¬†Of course, these are just guidelines I’ve picked up from my time at NUNM. I’ve noticed at conferences or when talking to other students from other schools, they observe different conventions.

2. The physical, material organ isn’t necessarily the most important part.

Probably the most important thing to understand is that the classical Chinese view doesn’t stop at gross anatomy. Although the ancient Chinese did investigate the inside of the body and were clearly aware of the physical structures that Western medicine now names “organs” this is not primary for the medicine’s understanding. The organ is included in a larger concept that is often called the “organ system,” which you have already seen me use many times. This organ system includes the physical organ, it’s associated channel(s), the tissues, surfaces, functions and other bodily features associated with that organ and other more rarefied aspects of the system.

3. The organ systems work together as a dynamic whole.

While each system has specific functions and can be talked about in isolation, the beauty of the Chinese medical view of the body only becomes truly apparent when you focus on the interconnections. No system is complete without seeing its relationship to the rest. This can make it a little confusing to study because our brains seem to find it simpler to focus on one mono-dimensional thing at a time.

4. The organ systems are a reflection of the macrocosm.

This principle relates back to Chinese philosophical understanding of the holographic nature of reality. For a complete review of the holographic worldview, see Michael Talbot’s The Holographic Universe. The basic gist of this philosophy is that the fundamental nature of reality is reflected in its smallest pieces just as much as in its largest. The small reflect the large, and the large reflect the small – they’re both reflecting something much deeper than themselves. In Chinese medicine we study this principle all the time.

On one level, each organ is a reflection of all the others – the parts reflect the whole. On another level, the total complex of organs and each organ individually reflect some aspect of nature. For example, the Heart reflects the nature of our Sun and acts as such within the body. Understanding these layers of meaning help us to fully comprehend the human body, and studying the human body through this lens helps us to gain a greater understanding about the Universe.

5. Following from that, then, the organ systems can be understood using various types of symbols.

Learning about the Chinese concept of the body was much easier once I learned to think about it as an ecosystem or as a country. With the former, I could simply walk in nature in a mindful way and reflect on the various features I found there. IS the Heart like the Sun? What would that mean if it were? How does that bear out in diagnosis? In treatment?

I think this practice does its work on more subtle levels as well – it must be why we are constantly urged to spend time in nature as CCM students. Using metaphors about the government helped me a great deal in understanding the functional relationships between organ systems. If the Heart is like the Emperor (or Empress) then what relationships should I see between it and the Lung, which is said to be like the Prime Minister?

6. The organs’ interrelationships are therapeutically useful.

Far from being a simple intellectual exercise, understanding the organ systems as networks of interrelationship bears out in treatment. Take the example of a problem that you determine is centered around some dysfunction of the Heart organ system, say palpitations. Thinking too simplistically, you might focus on the Heart channel, or maybe the paired Small Intestine channel. You would find points on those and other channels that are known to impact the Heart. Perhaps you would prescribe some herbs associated with the Heart organ system.

This simplified approach would miss out on the therapeutic benefit of considering the interrelationships of organ systems. Instead – quickly review a few of the most well known organ system relationships to increase nuance. Is fire failing to be generated by wood? Being reversely controlled by metal? Perhaps thinking about the six conformations could have us considering how Kidney water might influence the Heart and create palpitations. Through leveraging this more nuanced reasoning, we’ll find many more treatment approaches – and most of the more effective than the simplified reasoning would engender.

7. Even with this complex understanding – the organ systems are not PRIMARY.

In a sense, the organ systems are simply a useful way of organizing the overwhelming amount of information we can get from studying the human body. It is a convenient way because it has clear physical correlates. But we must also consider the fluids of the body (Qi, Blood, Jing, Shen, JinYe) as well as any more subtle aspects of the human being. We must also keep in mind that the body is not just a jumble of parts, but a integral functioning whole – when we treat we are not “tonifying the Kidney” but instead having a specific kind of impact on an infinitely complicated system using a particular technique. Maybe that’s splitting hairs, but it seems an important distinction.

There’s a lot more to know – but that’s a good start. Please put any questions or thoughts in the comments!

    I had heard that times you spontaneously wake at night can relate to a posible issue with various organs, depending on the time your waking. Is there anywhere you can point me to to explore this further in order to pinpoint and treat the body???

  2. Eric says:


    Thank you for your comment. Some have theorized that people wake during the two hour periods corresponding to certain organs. For instance, people who wake habitually between 11pm and 1am may either have a problem in the GB system, or the system across the organ clock – the HT. I have never heard a particular robust account of this theory, and most practitioners I know use it as a relatively minor piece of diagnostic information among the larger amount of information provided by the pulse, tongue and the rest of the history taking.

    In general – the organ time correspondences are as such:

    Heart: 11-1pm
    Small Intestine: 1-3pm
    Bladder: 3-5pm
    Kidney: 5-7pm
    Pericardium: 7-9pm
    Triple Burner/Heater: 9-11pm
    Gall Bladder: 11-1am
    Liver: 1-3am
    Lung: 3-5am
    Large Intestine: 5-7am
    Stomach: 7-9am
    Spleen: 9-11am
    … back to Heart

    I hope this helps.

    Hi Eric, Karina,

    Enjoying your articles Eric and I like Karina’s question on nightly waking.

    Apart from other considerations, I would suggest Solar Flares to be influential and affecting
    one’s personal magnetism. We can specifically note behavioral change in young children, as,
    if not linked to Solar Flare, this could soon result in diagnosis for ADHD, because it is where around Solar Flares their behavior becomes so charged, so energized, that a simple ‘can you please calm down’ wouldn’t work at all.

    Around Solar Flares, it is not that I wake up, then immediately fall back to sleep, but at times
    of Solar Flare, I’d have to actually get out of bed and be active for about 2 or 3 hours, then back to bed. The funny thing being, the spouse may wake up also, all independent of one another.

    Some people get overactive, others become pretty laborious, yet others complain of anxiety. Either way, it is like the Solar Wind resulting from Solar Flare ‘implodes’ into our system, then needs find a way out, so that in case of children, the ‘processing’ involves just going out with them and have them run, run. Here, the body is being given the chance to discharge the excess and sort of direct the energy to earth, just as in electricity. Solar Flares may affect the atmosphere in the house, so that with no any obvious cause, all get restless, like in adrift.

    It pays off to doing web searches on Solar Flare, Solar Storm, Sun Spots, earth magnetosphere, Solar minimum and Solar maximum and include this in your physiological calendar for advance and retreat.

    Be well,
