Keep Your Energy Strong
If the energy of meridians becomes thin and deficient, the cold energy may pass through it to attack the viscera and bowels and cause fear and shock. If the nutritive energy becomes disordered and flows upstream in between the flesh and muscles, swelling of carbuncle may come about as a result.
lf the wind and cold attack the person while he is still perspiring, all the points on the skin are shut up with the result that energy of heat is locked inside the body which will cause a disease called wind malaria in autumn.
