The manifestations of yang deficiency:
1, cold, cold limbs.
This is the most important symptom of yang deficiency. Yang is like the sun in nature. Without it, the internal environment would be "cold".
2, the end of the valley does not change.
It means that the stool is mixed with undigested food. The ancients had an image metaphor for this phenomenon. The digestion of food is like cooking raw rice into cooked rice, the stomach is like a cooking pot, and the yang is like a fire for cooking. Rice can't be cooked without fire. Therefore, when the yang is insufficient, the food entering the stomach cannot be "decomposed" (digested) well and directly discharged from the intestine.
3. Lack of energy.
Yang deficiency, cell life activities decline, so it is listless and lazy.
