TCM 101: The 5 Elements + the “5 Organs” (how Organs in TCM differ from Western medicine)

If you’ve heard from a TCM practitioner that your “Spleen Qi is weak” (and you wondered if your biomedical Spleen was needed to do more reps at the gym, maybe?), here’s a quick explainer. Traditional Chinese Medicine (TCM) uses familiar organ names, but the definition is completely different.

TCM worldview is anchored in ecosystem thinking and comes back to patterns: how your whole system interacts with your environment—food, weather, emotions, stress, sleep, work pace, and even Singapore’s heat + humidity.

A simple way to understand this worldview is through the 5 Elements: Wood, Fire, Earth, Metal, Water. You might think of them like a pond ecosystem from your primary school biology classes, where there were plants, insects, birds, fish, water, soil and everything else. Each part creates the whole and affects each other.

The body in TCM: You’re a mini ecosystem

In a biomedical lens, the body is viewed like a machine: parts, organs, functions all dissected and specialised.

In TCM, the body is more like a living landscape. You’re a mini ecosystem - you can even think of yourself as a little planted aquarium. If the soil is weak and lacks nutrients, plants struggle. If the plants struggle, they might not be fixing the nitrogen they should. If water level is low, you can’t cool the system or the toxic components concentrate. If the temperature is too high, certain species of fish just can’t thrive.

So when symptoms show up, TCM often asks:

  • What is pattern underneath the immediate symptom?
  • What’s the root cause driving it? (Or TCM’s aim to 对症下药）

Symptoms are only the surface signal, which is how the same symptoms might have different treatments at a TCM clinic.

Beyond that, TCM also believes in 调理, or to calibrate and adjust in lifestyle, 养生, or cultivating life through small, consistent daily actions and 药食同源, or that food and medicine come from the same source, which is the philosophy behind the teas here at Apothecary Brew.

What are “TCM Organs” exactly?

When TCM says Liver, Spleen, Heart, Lung, Kidney, it includes the physical organ but comprises a whole Organ System.

A TCM Organ System includes:

  • a set of functions (digestion, circulation, regulation, etc.)
  • an emotional/mental aspect
  • connections through channels (meridians)
  • relationships with other organ systems

What are the 5 Elements (and their Organ pairs) in TCM?

In quick summary, this is the map for the 5 elements. Each element paired Organ System has a lot more detail, which we can expand on at another time.

  1. Wood → Liver + Gallbladder

Wood is growth, movement, direction, and flexibility.

When Wood is balanced, you feel:

  • motivated, decisive, able to plan
  • emotionally “unstuck”
  • physically flexible (in a broad sense)

When Wood is strained (very common with chronic stress), you might notice:

  • tension, tight shoulders/neck, headaches
  • irritability, frustration, mood swings
  • feeling “wired but tired”

2) Fire → Heart + Small Intestine

Fire is warmth, joy, connection, and clarity.

When Fire is balanced:

  • you feel present, calm, emotionally steady
  • sleep is restorative
  • your mind feels clear, not scattered

When Fire is excessive or unstable:

  • restlessness, anxiety, overthinking
  • insomnia, vivid dreams
  • feeling “overheated” emotionally or physically

3) Earth → Spleen + Stomach

Earth is nourishment, digestion, groundedness, and stability.

In TCM, Spleen is central to transforming food into energy (Qi) and fluids. It’s not the same as the anatomical spleen.

When Earth is strong:

  • steady energy, good appetite, good focus
  • you feel centred
  • digestion is smooth

When Earth is weak (also super common in humid climates + busy schedules):

  • bloating, loose stools, sluggish digestion
  • fatigue after meals
  • brain fog, heavy limbs
  • cravings for sugar to “push through” (we can talk about cravings another time)

Singapore Note: humidity adds external “Dampness” in TCM, which has an influence on internal “Dampness”. Dampness + weak Earth = the “why am I so heavy and tired?” combo.

4) Metal → Lung + Large Intestine

Metal is breath, boundaries, immunity, and letting go.

When Metal is balanced:

  • breathing feels easy
  • skin is healthy
  • you recover from stress and illness well
  • you can release what you don’t need (physically + emotionally)

When Metal is out of balance:

  • frequent colds, allergies, sinus issues
  • dry skin or dryness overall
  • grief that feels stuck, or emotional sensitivity
  • constipation or difficult bowel movements

5) Water → Kidney + Bladder

Water is reserves, endurance, deep rest, and long-term vitality.

In TCM, Kidney is linked to foundational energy and resilience (again, not only the biomedical kidney). Unlike energy from the Spleen, Kidney energy is said to be finite (omg!)

When Water is supported:

  • you feel steady, grounded, resilient
  • recovery happens faster
  • you can sustain effort without crashing

When Water is depleted:

  • chronic fatigue, burnout feelings
  • lower back weakness, feeling cold easily
  • anxiety with a “existential” edge
  • sleep that doesn’t recharge you

Side note: if you’re constantly running on adrenaline, you can look “fine” until you suddenly aren’t.

How imbalance shows up: it’s rarely just “one organ”

Symptoms show up when relationships between systems come out of balance.

For example:

  • Chronic stress tightens Wood (Liver).
  • Overactive Wood can “attack” Earth (Spleen/Stomach).
  • Then indigestion and gastric discomfort comes up, appetite might drop so energy also drops.
  • You feel foggy, bloated, gassy and more reactive.
  • Which makes stress worse. Nice little horrible loop we have.

This is why many urban patterns cluster around:

  • Liver-related imbalances (stress + tension + sleep disruption)
  • Spleen deficiency / Dampness patterns (fatigue + bloating + heaviness)

How should I approach self-understanding with TCM info?

If you’re new to TCM, don’t try to self-diagnose perfectly. If you can, seeing a practitioner for a diagnosis can also give you a roadmap. In the meantime, browse our site as we’ll keep sharing more details.

Start by observing patterns:

  • What makes symptoms worse: stress, late meals, heat, lack of sleep?
  • What helps: walking, warm foods, earlier bedtime, less stimulation?
  • Do you swing more toward “tense and wired” (Wood/Fire) or “heavy and tired” (Earth/Water), or “dry and sensitive” (Metal)?

Lastly, as with any living landscape, your classification will keep shifting over time, as you make different lifestyle choices in response. We hope knowing which Organs are most out of balance will help you get a clear direction for right now.

Lastly, like any living landscape, your patterns can shift over time — especially as stress, sleep, food, and routines change. Use TCM as a way to notice trends, not to label yourself permanently.

If you’re curious, I’ll be sharing more beginner-friendly TCM guides like this. And if you want a practical starting point right now, browse our teas — they’re designed around common modern patterns (like stress tension and “heavy + tired” digestion days) to support you where you are today.
