Why Acupuncture Research Seems “Inconsistent” — and Why That Doesn’t Mean It Doesn’t Work

Author: Dr. Richard Zeng Acupuncturist Melbourne TCM Doctor

If you’ve ever searched “Does acupuncture really work?” you’ve probably found yourself confused. One article praises it for relieving pain or anxiety, while another insists it’s “no better than placebo.”

So, which is true?

The answer isn’t that acupuncture doesn’t work — it’s that we’re often trying to measure it with the wrong tools. We’re using a drug-based research model to assess a body-based healing system.

Let’s unpack what that means — and why it matters for anyone considering acupuncture.

1. Acupuncture Isn’t an “Action” — It’s a “Reaction”

This is one of the most important distinctions to understand.

A drug is an Action — it imposes a chemical effect on your body whether your body agrees or not.

Acupuncture, on the other hand, relies on your body’s Reaction — the way your nervous system and energy respond to precise stimulation.

A good acupuncturist isn’t just inserting needles; they’re inviting your body to participate in its own healing. The effectiveness depends on your body’s ability to respond — and the practitioner’s ability to elicit that response.

2. Technique Matters — It’s All About the “Switch”

Here’s a simple example from clinical practice.

There’s a famous point called Zusanli (ST36), often used for nausea or morning sickness.

When it’s needled correctly — perpendicularly and to the right depth — we wait for the body to respond.

Sometimes, the muscle twitches gently, and the patient might feel a sensation travel down the front of the leg to the second toe — along the Stomach Meridian.

That switch isn’t random — it’s the body’s reflex, a sign the system has responded.

At that moment, nausea can ease almost instantly – and I call ST36 “the Nausea Switch”

But if the technique isn’t right — the angle, depth, or timing — that “switch” might not turn on.

This is why two practitioners can use the same point and get different results. It’s not inconsistency — it’s sensitivity.

3. Why Research Results Are So “Inconsistent”

Most acupuncture studies are designed using drug-trial logic: fixed doses, standardised protocols, and placebo (sham acupuncture) controls.

But acupuncture doesn’t work that way. As:

• Every Patient’s Reaction is Unique. In clinical trials, everyone gets the same acupuncture points. But in real practice, no two patients are treated the same way — because their reactions differ.
• Sham Acupuncture Causes Reactions Too: Even “sham” acupuncture — shallow or off-point needling — can trigger physiological reactions like endorphin release or nerve activation.
• Practitioner and Patient Variability: Just as each patient reacts differently, they may also react differently to different practitioners. The practitioner’s touch, skill, and sensitivity matter. Acupuncture is not a machine process; it’s a living interaction.

So when researchers try to “standardise” acupuncture, they’re stripping away its interactive nature — the very thing that makes it effective.

As I explained in my article Why Most Acupuncture Research Is Low Quality, this mismatch between research method and treatment reality explains much of the confusion.

4. Qi: Energy or Physiology?

In Traditional Chinese Medicine (TCM), we talk about Qi (energy flow).

In modern terms, Qi can be seen as the body’s communication network — involving nerves, fascia, and microcirculation.

When you feel the “De-Qi” sensation — a dull ache, heaviness, or spreading warmth — it reflects activation of your nervous and connective tissue networks.

So, whether we call it Qi or neurovascular response, the goal is the same: restoring the body’s internal balance and flow.

5. Beyond Placebo: What the Science Shows

Modern research does show measurable physiological changes:

• Brain imaging (fMRI) reveals changes in pain and stress-related regions.
• Studies show releases of endorphins and serotonin after acupuncture.
• Acupuncture regulates cortisol, improves blood flow, and modulates inflammation.
• It even works in animals — from horses to dogs — where the placebo effect can’t apply.

So, while a calm mindset helps any treatment, acupuncture’s effects are far more than belief alone.

Final Thought: Healing Is a Conversation, Not a Command

Acupuncture doesn’t force your body to change — it gently reminds it how to heal.
Each treatment is a dialogue between practitioner and patient, needle and nerve, action and reaction.

So the next time you see “mixed results” in the headlines, remember: inconsistency in research doesn’t mean inconsistency in healing.

The best way to understand acupuncture is to experience how your own body reacts.
