Monday mornings are usually quiet for me. I try to stay off social media unless there’s real intention behind it, partly because I’m experimenting with how my memory feels when I’m not flooded with irrelevant information and fascinating facts.
So, while doing my usual morning tidy, I decided to put on a podcast. I came across The First Years of Acupuncture by Kenton Sefcik, a Canadian acupuncturist and teacher whose work I’ve loved since I first started seriously studying Traditional Chinese Medicine (TCM). I’ve taken several of his courses, including the Pacific Rim College Online Register Acupuncturist Pan-Canadian Exam Bootcamp and his The Strength of TCM membership, and I always learn something new from him.
That morning, I pressed play on Episode 4, The 4-Step Tongue Diagnosis. I ended up sitting down midcleanup to take notes.
A Little Background
I first learned tongue diagnosis in Diagnostics in Traditional Chinese Medicine A at the Canadian College of Acupuncture and Traditional Chinese Medicine (CCATCM). It was one of my favourite parts of the course, equal parts science and poetry.
We learned to observe shape, color, coating, moisture, and movement, and we even did presentations analyzing the tongues of our friends and family members. It’s incredible how much the body reveals if you know how to read its language.
Tongue diagnosis is one of the pillars of TCM assessment. Alongside pulse, palpation, and questioning, it helps us understand the internal landscape of the body, the “where” and “why” behind symptoms.
But unlike a Western diagnosis, it’s not about labeling disease. It’s about identifying patterns of imbalance so we can support the body’s natural movement back toward harmony.
What It Means When I Ask to See Your Tongue
If you’ve ever been to a TCM practitioner and they ask, “Can I see your tongue?” here’s what’s happening.
We’re not checking for oral hygiene or looking for signs of strep. We’re observing your internal terrain.
The tongue reflects what’s happening inside, and each area corresponds to an organ system:
- The tip connects to the Heart and Lungs
- The sides to the Liver and Gallbladder
- The center to the Stomach and Spleen
- The root to the Kidneys and Bladder
Now, before you start worrying that your acupuncturist is diagnosing liver failure from your tongue, take a breath.
When we talk about the Liver or Spleen in Traditional Chinese Medicine, we’re not referring to the literal Western organs you’d see on a scan or in a lab test. They’re more like organ systems, energetic and functional networks that describe how the body moves, digests, feels, and adapts.
You can think of them like characters in a story, each with a role, a personality, and relationships with the others. The Liver system, for instance, governs flow, of blood, of emotions, of movement. The Spleen system transforms nourishment into energy. The Heart holds the spirit. It’s poetic, but also deeply practical once you learn the language.
So when I say, “your tongue shows a bit of Liver Heat,” it doesn’t mean your physical liver is damaged. It means the Liver system, the part of you responsible for smooth flow, might be running a little hot, tight, or stressed.
My job is to interpret those signs and translate them into gentle, practical steps to help your body rebalance.
How to Show Me Your Tongue (the Right Way)
Kenton says it best:
“Stick it out like a dog on a hot day — relaxed.”
That means:
- Not so far that the tip tenses up and turns red (that can give a false reading).
- Not barely out, either — I need to see the whole picture.
- Try not to move it too much while I’m observing.
And a few pro tips:
- Avoid coffee, blueberries, or candy right before your appointment. They can temporarily stain or heat the tongue and change what I see.
- Don’t scrape your tongue the morning of your appointment, the coating is part of the diagnostic picture.
- If you’re sick, don’t worry about it looking “bad.” That’s valuable information.
Over time, experienced practitioners learn to tell the difference between true changes and temporary ones, like “coffee heat” versus genuine internal heat, or the bluish tint from blueberries versus signs of Blood stasis.
What the Tongue Can Reveal
What’s most fascinating is how this one simple observation can guide our questions. Sometimes, before I’ve even asked, the tongue will point me toward what’s really happening, whether someone’s been struggling with digestion, experiencing loose or dry stools, feeling anxious, or having trouble sleeping.
Patients are often amazed when I can describe their symptoms just from that first glance. That’s not magic, it’s pattern recognition, built on thousands of years of careful observation.
Thinking in Points
Kenton teaches something I love: after observing the tongue, think in acupuncture points.
For example:
- Red sides → Liver Heat or Fire → might call for LV2, the Liver’s spring point, to clear that excess heat.
- Thick greasy coating → Dampness → might lead me to SP9 and ST40, classic points for draining Damp and phlegm.
It’s a way of bridging the diagnostic and the practical, seeing the pattern, then immediately thinking about how to shift it.
For My Fellow Students
If you’re still finding your way through the maze of tongue diagnosis, I highly recommend Kenton’s The First Years of Acupuncture podcast. It’s honest, clear, and full of grounded wisdom from someone who remembers what it’s like to be in our shoes.

For My Future Patients
When you come to see me, tongue diagnosis is just one of the tools I’ll use to understand you — your patterns, your rhythms, your story.
It’s not about judgment or superstition, it’s a quiet, ancient way of listening to the body.
And like everything in Traditional Chinese Medicine, it’s a conversation, between practitioner and patient, between body and balance, between what’s seen and what’s felt.
A Gentle Note: I’m a student of Traditional Chinese Medicine, and this space reflects my learning as it unfolds. TCM is deep, layered, and complex, and I’m still finding my footing within it. I will refine my understanding over time. I will make mistakes. That’s part of doing this honestly. What I share here is my current perspective, shaped by my teachers, clinical training, lived experience, and my own biases. It’s not absolute, it’s evolving. I welcome thoughtful conversation, shared insight, and respectful correction along the way. I humbly welcome your insight. Let’s learn together. You can always find me over on Instagram to keep the conversation going.
