It is not recommended to consume American ginseng, as it will easily lead to the aggravation of discomfort and is not conducive to the early recovery of the disease. Most of the symptoms of running nose are caused by wind-cold cold, and the body is invaded by wind-cold evil; American ginseng is cold in nature, tonifying qi and nourishing yin, clearing heat and generating fluids. It can be used in treating deficiency of qi and yin, deficiency of heat and tiredness, coughing, wheezing, phlegm and blood, internal heat and thirst (internal heat accompanied with symptoms such as eating, drinking, urinating, etc.), and dryness of mouth and pharynx. Radix Panax Ginseng can injure yang and help dampness, and should be taken with caution for people with yang deficiency, internal cold and cold-dampness; therefore, if people with wind-cold and flu consume Radix Panax Ginseng, it is likely that it will lead to limb aches, weakness and worsening of symptoms such as running nose and throat. It is suggested to strengthen personal warmth care during the period of clear running of mucus, avoid the adverse stimulation of wind-cold, drink more warm water, and give pungent, warm and antidepressant medicines under the guidance of traditional Chinese medicine practitioners, so as to promote the early recovery of the above mentioned symptoms, and to avoid blindly eating and blindly using medicines, etc., so as to ensure the safety of the patients.
