White radish as a food does not have a therapeutic effect, so white radish decoction drink can not treat colds.
Although white radish as a food has certain benefits to the human body, but does not have the role of treatment of disease, there is no research evidence that white radish has the role of treatment of colds.
People with colds can choose Chinese herbal tonics according to different types of symptoms. For example, for those with wind-cold symptoms, Jingpangdaepiao Tang is used to relieve the symptoms with pungent warmth; for those with wind-heat symptoms, Yinjiao San is used to relieve the symptoms with pungent coolness; and for those with summer-damp symptoms, Elsholtzia Drink is used to relieve summer heat and relieve symptoms with clearing the symptoms.
For colds with deficiency of qi, ginseng-su drink is chosen to benefit qi and relieve the exterior; for colds with deficiency of yin, Weiweiwei Tang is chosen to nourish yin and relieve the exterior.
The above formulas and specific medicines should be chosen under the guidance of a doctor. It is recommended that people with colds should consult a professional doctor in time.
