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

Wind-heat cold is generally a cold 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. Eating Lianhua Qingwen is symptomatic, because the prescription of Lianhua Qingwen contains mint and ephedra, which can make people sweat and dissipate wind-heat. Flos Lonicerae and Fructus Forsythiae can clear away lung heat, which is also very effective for wind-heat cold.
