According to "Classification and determination of TCM constitution" published by China Association of Chinese Medicine (CACM) in 2009, the TCM constitution can be classified into nine basic types: balanced, qi deficiency, yang deficiency, yin deficiency, phlegm-dampness, damp-heat, blood stasis, qi stagnation, and allergic constitution.

GGT-1 is used to treat serious Yang deficiency syndrome, and symptoms include spontaneous perspiration, chills, dry throat, leg cramps, dizziness, vomit, and frequent urination, in Shang-han-lun by Zhongjing Zhang, while GGT-2 is applied to relatively mild lung deficiency, and symptoms include cough, dyspnea, and asthenia, in Jin-kui-yao-lue.

In this study, EFA results indicated that the syndrome pattern blood stasis was highly associated with qi deficiency, qi stagnation, phlegm turbidity, and heat, whereas association of yang deficiency with the same syndrome patterns was significantly lower.
Interestingly, analysis of all syndrome patterns showed that frequency of yang deficiency was significantly lower than that of qi deficiency, qi stagnation, phlegm turbidity, and heat.
Compared to males females showed significantly more serious Yang deficiency (Table 5(a)), but age was not correlated with Yang deficiency.
The classification criteria of syndrome elements were (1) six-excess external contraction: wind, cold, dampness, dryness, and fire; (2) five endogenous qi: internal wind, internal cold, internal dampness, internal dryness, and internal fire; (3) factors related to gas: qi deficiency, qi stagnation, qi block, qi counterflow, qi fall, and qi collapse; (4) factors related to blood: blood deficiency, blood stasis, blood collapse, blood dryness, and bleeding; (5) factors related to yin and yang: yin deficiency, yang deficiency, yin exuberance, and yang hyperactivity; (6) others: poison, excessive fluid, and phlegm turbidity.
The syndrome element date we have measured in the experiment includes forty-five indicators: Yang Deficiency, Yang Hyperactivity, Exterior, Qi Deficiency, Qi Sinking, Qi Counterflow, Blood Stasis, Blood Cold, Stirring Wind, Retained Fluid, Fluid Depletion, External Wind, Summer Heat, Dryness, Food Accumulation, Gallbladder, Large Intestine, Stomach, Bladder, Small Intestine, Chest and Diaphragm, Sinew and Bone, and so on.
The Yang deficiency constitution is linked to a series of cold symptoms characterized by a cold body and limbs owing to an insufficiency of Yang qi, which fails to warm the body and leads to a Yang deficiency-induced internal cold (cold-intolerant) [2].
TCM constitutional types are commonly assessed using Wang's 'Rule of Nine.' [3] A previous report by Lin and colleagues [4] found that the most common TCM constitutional types in persons with mild cognitive impairment were 'qi deficiency' (22%) (i.e., inability of qi and blood to nourish the body), 'blood stasis' (18%) (i.e., poor blood flow), 'yang deficiency' (17%) (i.e., lack of body warmth), and 'phlegm dampness' (11%) (i.e., blockage of other body fluids).
