How is the wind-heat type cold caused? Is it symptomatic to eat Lianhua Qingwen?

Wind-heat cold is generally caused by hot weather when the body's immunity is low and the body needs it more. The main symptoms are headache, stuffy nose and fear of wind. It is symptomatic to eat Lianhua Qingwen, because the prescription of Lianhua Qingwen contains mint and ephedra, which can make people sweat and dissipate wind and heat. Honeysuckle and forsythia are also effective in clearing away lung and heat.
