Su Wen, lifting pain theory “Yu know hundred diseases born in the gas, anger is gas, happy is gas slow, sad is gas, fear is gas down, cold is gas collection, Gui is gas discharge, alarm is gas chaos, labor is gas consumption, thinking is gas knot, nine gas different, what disease is born? Qibo said: anger is reversed, even vomiting blood and food, so the gas is carried on. Joy is the gas and Zhi Da, Rongwei Tongli, so the gas is slow. Sadness is the heart is anxious, the lung cloth leaf lift, and the upper jiao is not accessible, Rongwei does not disperse, heat in the, so the gas is eliminated. Cold, the couples are closed, the Qi does not work, so the Qi is collected. Gui is the coup open, Rongwei pass, sweat, so the gas leak. The heart has nothing to rely on, God has nothing to return, nothing to set, so the gas is disordered. Labor is panting and sweating, outside and inside are over, so the gas is depleted. Thinking is the heart is stored, the gods have returned, the right qi stay and not work, so the qi knot carry on.” From this, we can see that only “happy is the gas and Zhi Da, Rong Wei Tongli, so the gas is slow”, is a relatively good mood, conducive to the harmonization of blood, blood vessels flow. Then, it is important that we maintain an optimistic mood in life, which is conducive to physical health. And bad emotions, more or less, will affect our body and should be avoided as much as possible!
