The language of TCM

In Chinese medical thought, qi describes processes of movement, transformation, warming, protection and containment. Translating it simply as ‘energy’ can conceal this range of meanings. It is not a measurement in joules, an oxygen level or a synonym for electricity.

Example: A practitioner might speak of ‘qi deficiency’ when interpreting a collection of symptoms. This is a traditional pattern, not a blood-test result.

Yin can describe relative coolness, rest, inwardness and substance; yang can describe warmth, activity, outwardness and function. The terms depend on context. Neither is inherently good or bad, and balance is a changing relationship rather than a fixed fifty-fifty ratio.

Example: Rest after exertion illustrates a shift in relative activity. It cannot diagnose a person as permanently ‘yin’ or ‘yang’.

Also called Five Elements, this is a model of transformation and relationships. It links phases with seasons, tastes and functional networks. The labels are symbolic categories, not chemical elements or five literal substances inside organs.

Example: Wood is associated with spring and growth. This is an analogy within the tradition, not a finding about liver chemistry.

A traditional concept connected with development, reproduction and the resources of life. Some accounts distinguish inherited and acquired aspects. It should not be equated directly with DNA, hormones, semen or a measurable store of life expectancy.

Example: A discussion of ageing may use the language of jing; this does not replace examination of bone health, strength or endocrine function.

Its meaning varies across medical, philosophical and religious contexts. In medicine it is often discussed in relation to awareness, sleep and emotional life. Translating shen as only ‘the brain’ or only ‘the soul’ loses part of the concept.

Example: A practitioner may observe alertness and demeanour. Mental-health symptoms still deserve an appropriate clinical assessment.

The term includes nourishing and moistening functions in TCM. Although it overlaps with the ordinary word for blood, ‘blood deficiency’ or ‘blood stasis’ are traditional categories and do not map directly to anaemia or a blood clot.

Example: ‘Blood deficiency’ cannot confirm low haemoglobin. Suspected anaemia requires suitable clinical investigation.

A traditional grouping of fluids that moisten and nourish tissues. Practitioners distinguish finer and thicker fluids in their theory. The categories are not a substitute for measuring hydration, kidney function or electrolytes.

Example: Dryness may be discussed using this language, while medicines, environment and medical causes also need consideration.

Names such as Liver, Heart, Spleen, Lung and Kidney refer to broader traditional networks as well as bodily organs. English texts often capitalise these names to signal the difference. There is no exact anatomical translation for every function.

Example: A TCM ‘Spleen’ pattern does not mean that the anatomical spleen is diseased.

These organise relationships between regions, functions and acupuncture points in traditional teaching. Classical maps commonly describe twelve primary channels and eight extraordinary vessels. They are not established anatomical tubes or a replacement map of nerves.

Example: A meridian chart is a map within a medical tradition. It should not be used as a home needling guide.

The interpretation of a cluster of observations within a traditional framework. Two people with the same biomedical diagnosis may receive different TCM pattern descriptions, while different biomedical diseases may share a traditional pattern.

Example: The terms ‘disease’ and ‘pattern’ answer different questions; one cannot safely be substituted for the other.

Broad descriptors used in pattern assessment. Deficiency refers to a perceived insufficiency of a function or resource; excess refers to a perceived predominance or obstruction. These words are not simple judgements about body size or nutritional intake.

Example: An ‘excess’ pattern is not a diagnosis of obesity, and ‘deficiency’ is not proof that supplements are needed.

Traditional descriptions of patterns and the qualities attributed to foods or medicines. Their meaning extends beyond a thermometer reading. A food called ‘warming’ is not necessarily served hot or shown to raise core body temperature.

Example: A temperature reading and a ‘heat’ pattern are separate kinds of information.

A traditional pattern term associated with heaviness, sluggishness or fluid-related descriptions. The transliteration resembles shi meaning excess, but the Chinese character and meaning differ. It is not a proven physical residue that a detox product can flush out.

Example: Swelling needs assessment for its actual cause; describing it as dampness is not enough.

A broad culture of cultivating daily life through habits such as rest, movement, eating and attention. It extends beyond a single medical procedure and has taken different forms across history.

Example: A regular routine can be meaningful without making a claim that it prevents every illness.
