The main symptoms of wind-cold invasion include chills and fever, presence or absence of sweating, headache, body aches, floating tight pulse, and white tongue coating. Some other symptoms include nasal congestion, clear nasal discharge, cough, watery sputum, or stifling sensation at chest which relates to Lung Qi stagnation. Based on the treatment principle that when the problem is at the skin level, the sweating method is used to release the exterior, this type of syndrome often uses releasing-exterior and promoting-sweating herbs such as Ma Huang, Gui Zhi, Xi Xin, Zi Su Ye, Jing Jie, and Fang Feng as the chief herbs in a formula. These formulas are warm, acrid, and releasing-exterior, which can promote the dispersing function of the Lung and expel evils.
