Wind-cold syndrome herb selection

These three herbs are able to expel wind, cold and dampness from the skin, subcutaneous region and muscles. They can be selected as chief in a formula to treat a severe excess condition of wind-cold syndrome. 

Xi Xin is a very pungent and hot herb with an aromatic smell. It does not enter the Bladder meridian, but does enter the Kidney meridian. It can be selected as deputy in the formula to enhance the action of the chief herbs in treating an excess condition of wind-cold syndrome and can release pain. 

Sang Ye and Ju Hua are bitter, sweet and cold, and enter the Lung and Liver meridians. They are often selected as chief herbs in the formula to treat a mild wind-heat syndrome when the wind-heat mainly affects the Lung. 

At the initial stage, the first priority is to select pungent-cold herbs or bitter-cold herbs that can effectively reduce heat-toxin, along with herbs that expel wind. They can prevent the development of the syndrome.
