"Looking, listening, asking, and feeling" — these are the four foundational diagnostic methods in Traditional Chinese Medicine (TCM). Many people recognise the phrase but are unsure what each examination actually involves. This article explains what each of the four examinations covers, how they are conducted in a consultation, and which ones can be done online.
HansMed Modern TCM offers online video consultations, so we also want to be honest about the differences between online and in-person visits. This does not mean online consultations are a "compromised version" of TCM — it simply means a systematic pattern-differentiation (辨证) assessment is carried out using the remaining three examinations.
1. Looking (望): More Than Just Complexion
The first of the four examinations is the most direct. The practitioner observes your overall state — energy level, body type, complexion, and importantly, the tongue. In TCM theory, the tongue is understood to reflect the condition of the internal organs.
In an in-person visit, observation happens naturally face to face. In an online consultation, you can show your tongue clearly through the camera. The system guides you through capturing a clear tongue photo, which a registered practitioner then reads — the tongue is one reference among several in the assessment, and the registered practitioner's judgment is final.
A note: tongue analysis is a diagnostic method within TCM theory, for the practitioner's reference only. If you have any unusual symptoms in your mouth or tongue, please consult a doctor or dentist first.
2. Listening and Smelling (闻): Sound and Odour
This examination has two parts: listening to sound and detecting odour. The practitioner pays attention to the quality of your voice, the depth of your breathing, the character of a cough, and so on. As for odour — breath or body scent — modern clinical settings rely on this far less than in the past.
In an online consultation, the "listening" part can be done in full. Through video, the practitioner can clearly hear your voice and breathing. The "smelling" part cannot be done online — but it already carries less weight in modern TCM diagnosis, so the impact is limited.
3. Asking (问): The Most Important Step
This is where the practitioner gathers the most information. You will be asked about your specific complaint, when it started, what makes it better or worse, sleep, appetite, digestion, bowel movements, mood, and menstrual history where relevant. This information forms the main basis for the TCM assessment (辨证).
In an online consultation, the questioning can be done in full — and often more efficiently. You can answer from a quiet environment without the time pressure of a clinic room. The practitioner also follows up in real time to fill in any needed detail.
Before your consultation, prepare the following:
- Your main complaint and when it started
- What makes it better or worse
- Your usual sleep, diet, and bowel habits
- Any medications or supplements you are taking (including Western OTC medicines)
- Any past illnesses or surgeries
4. Feeling the Pulse (切): The One That Cannot Be Done Online
Pulse diagnosis involves the practitioner placing fingers on the radial artery at your wrist to sense the depth, speed, and quality of the pulse. In TCM theory, the pulse is understood to reflect the state of qi and blood in the body.
To be clear: pulse diagnosis cannot be performed in an online consultation. This is the most significant difference between online and in-person TCM. Online consultations simply work differently — in modern TCM practice, thorough asking and looking can already provide most of the essential diagnostic information; pulse-taking is one supplementary tool, not the sole basis for the assessment.
In an online consultation, the practitioner works with the other three examinations to form the assessment. If pulse-taking is considered essential for your condition, the practitioner will recommend an in-person visit. HansMed's in-person service is coming soon, and will offer the full four-examination assessment.
Comparison Table
| Examination | What It Covers | Possible Online? |
|---|---|---|
| Looking | Complexion, body type, tongue | ✅ Yes — tongue and complexion via camera |
| Listening & Smelling | Voice, breathing, cough | ✅ Yes — via video call |
| Asking | Symptoms, history, lifestyle | ✅ Yes — fully, often in more detail |
| Feeling the pulse | Pulse characteristics at the wrist | ❌ No — requires in-person visit |
FAQ
Q: Is an online consultation as effective as an in-person one?
A: Online consultations use three of the four examinations and are suitable for most common health and wellness concerns. If your condition requires pulse diagnosis, the practitioner will recommend an in-person visit. Each format has its place — neither is inherently superior.
Q: Can I get herbal medicine prescribed in an online consultation?
A: The practitioner will decide whether a herbal prescription is appropriate based on the assessment (辨证). Prescriptions are verified by a licensed pharmacist at our partner pharmacy before dispatch, typically within 1–2 working days in the Klang Valley.
Q: What is an online consultation suitable for?
A: Non-emergency wellness concerns such as sleep, digestion, stress, pain, and women's health. If you have an emergency or severe symptoms, call 999 or go to the nearest emergency department immediately.
Conclusion
The four examinations form the complete framework of TCM diagnosis, and each has its role. Online consultations can perform three of the four, with looking, listening, and asking combined (三诊合参) as the basis for the assessment.
