TCM Differential

TCM pattern differentiation for insomnia

‘Insomnia’ is too broad to differentiate directly. Start by identifying the disturbed part of sleep—falling asleep, maintaining sleep, early waking, dream disturbance or unrefreshing sleep—then test the pattern families that could produce that presentation.

Questions that open the right branches

  • What exactly happens: difficulty falling asleep, repeated waking, early waking, vivid dreams or non-restorative sleep?
  • Is the mind agitated, worried, fearful or simply unable to settle?
  • Are there palpitations, night sweating, five-centre Heat, thirst, bitter taste or mouth ulcers?
  • Is there epigastric fullness, reflux, nausea or late-evening food aggravation?
  • Are heaviness, chest oppression, phlegm or a greasy tongue coat present?
  • How longstanding is the problem, and what changed around its onset?

Pattern families to distinguish

CandidateUseful supporting clusterImportant separator
Heart FireMarked agitation, palpitations, thirst, mouth/tongue ulcersRed tongue tip and a rapid pulse with clear full-Heat signs
Liver FireIrritability, bitter taste, red eyes, headacheLiver Heat signs predominate rather than mouth/tongue-ulcer signs
Heart Yin DeficiencyDream-disturbed sleep, palpitations, night sweating, five-centre HeatDeficiency-Heat picture with thin rapid pulse rather than full excess
Heart–Kidney disharmonyInsomnia with palpitations plus tinnitus or low-back/Kidney signsBoth upper Heart agitation and lower Kidney deficiency evidence
Phlegm-HeatRestlessness with chest oppression, nausea or phlegmGreasy yellow coat and slippery rapid pulse
Food retentionRestless sleep after eating, epigastric fullness, belching or refluxClear digestive timing and retention signs

Timing is context, not a verdict

A recurring waking time can guide a follow-up question, but it does not establish an organ pattern. The accompanying symptom cluster, tongue and pulse determine whether that timing is meaningful.

Document sleep opportunity, schedule, substances, medication and environmental disturbance so a TCM hypothesis is not built on an unexamined non-pattern cause.

Move from reading to reasoning

Test the distinctions in an interactive case.

The assistant asks for evidence that can change the ranking and keeps missing observations visible.
