Lung and Large Intestine: A Season for Letting Go
As the evenings draw in and there's a crispness in the morning air, nature is quietly showing us how to let go. The trees are changing colour and shedding their leaves without a second thought, and that's a good place to start with this message.
In Traditional Chinese Medicine (TCM), the body is never seen as a set of separate parts. Everything is connected, and health depends on Qi, our vital energy, flowing freely. TCM groups the organs into five paired systems, one of which is the Lung and Large Intestine.
At first glance it's an odd couple. One sits in the chest and one in the abdomen, so what could they have in common? Thousands of years ago, practitioners observed that the two share a close energetic relationship. Things that look unconnected from one angle can turn out to be deeply linked when you step back and see the bigger picture.
The Lung is about more than breathing. In TCM it governs Qi throughout the body, taking in what's fresh and spreading it where it's needed. The Large Intestine has the opposite job: releasing what we no longer need. Between them they cover the whole cycle of receiving and releasing, a fine balancing act.
When one partner struggles, the other often feels it. Many people with breathing or Lung imbalances also notice changes in their bowel habits. The two also share a connection with the skin, so dryness, itchiness or dullness can be part of the same picture. TCM links the Lung and Large Intestine to autumn and to dryness, which is why many of us notice drier skin, tickling throats and sluggish digestion at this time of year.
What I love about this pairing is how well it fits current research. A functional medicine approach looks for the root causes of symptoms rather than simply managing them, and it has some fascinating information to share:
The gut–lung axis. Researchers are finding that the bacteria living in our gut influence immune responses in the lungs, and vice versa. The ancient observation of a Lung–Large Intestine link is getting modern support.
The gut–skin axis. Gut health shows up on the skin. Inflammation and imbalances in the gut microbiome are associated with skin conditions, echoing the TCM view that skin reflects this organ pair.
The gut–brain axis. The colon is far more than a waste-disposal system. It's home to trillions of microbes that help regulate mood, immunity and energy, and it communicates constantly with the brain.
Looking upstream. Constipation is incredibly common, and it's tempting to reach for something that forces things along. Yet regular laxative use treats the symptom rather than the cause. In functional medicine I ask why things have slowed down: hydration, fibre, stomach acid and enzymes, the microbiome, stress, movement and sleep can all play a part. TCM asks the same question in its own language, and often looks to the Lung.
As the temperatures drop in the Northern Hemisphere, our digestion appreciates a little extra kindness. TCM has long recommended favouring warm, cooked foods in autumn and winter. Cold, raw foods ask the digestive system to work harder, while gently cooked meals are easier to break down and absorb.
Some simple seasonal swaps:
Swap smoothies and salads for soups, stews, broths and slow-cooked dishes
Enjoy root vegetables like carrots, parsnips, beetroots, squash and sweet potato
Try stewed or baked pears and apples, traditionally used in TCM to moisten dryness
Add warming spices such as ginger, cinnamon and a little black pepper
Sip warm water or herbal teas through the day rather than iced drinks
Include fibre-rich foods like oats, lentils, beans and ground flaxseed to keep things moving and feed your gut bacteria
Letting go and slowing down
The Tao Te Ching teaches that to receive, we must first give away. The Lung and Large Intestine embody this beautifully: we can only take a full, fresh breath once we've breathed out, and we can only nourish ourselves well when we're able to let go of what's no longer serving us.
That applies emotionally too. In TCM, the Lung is linked to grief and letting go. Autumn invites us to release old habits, held-on worries and the busyness of summer. Feeling stuck emotionally is often mirrored by feeling stuck physically.
As we move towards the darker days of winter, it's natural to want to slow down, rest more and turn inwards, a gentle kind of hibernation. Rather than fighting it, we can lean in: earlier nights, slower mornings, nourishing meals and time to breathe deeply. A few minutes of slow, full breaths each day is a lovely way to support both partners in this pair, calming the nervous system and helping digestion along.
If your digestion has been feeling sluggish, uncomfortable or unpredictable, or if you'd simply like to feel more balanced going into winter, I'd love to help. My clinic is currently running online, so you can get support from the comfort of your own home, wherever you are. I work with Nutrition, Herbs and Homeopathy to harness balance for my patients, with a special focus on the Gut, Liver and Skin as well as Brain Health.
