The difference between wind-cold cold and wind-heat cold: wind-cold cold is caused by the invasion of wind-cold pathogens and the instability of lung qi. Symptoms can be seen: aversion to cold, mild fever, anhidrosis, headache and body pain, stuffy nose, cough, thin and white phlegm, thirst or thirst for hot drinks, thin and white fur.

Wind-heat cold is caused by wind-heat invading the exterior and disharmony between lung and qi. Symptoms are severe fever, slight aversion to wind, head swelling and pain, sweating, sore throat, cough, sticky or yellow phlegm, stuffy nose and yellow nose, dry mouth and thirst, red tongue tip, thin white and yellowish fur. Wind-cold cold is an attack of wind-cold in traditional Chinese medicine, while ginger is hot and can dispel external evils. If you have a cold, drink a bowl of hot ginger tea to make the patient sweat slightly, and the exterior evil will come out with the sweat, and the disease will be solved. So it is effective. But wind-heat cold is the internal resistance of true evil, and drinking ginger tea will aggravate the symptoms.
