Whether ginger water can have a therapeutic effect on coughs or not, it needs to be recognized and treated according to the patient’s condition. Ginger water is effective for coughs caused by wind-cold. Ginger water is usually decocted with ginger. Ginger is mildly warm and pungent in nature, and belongs to the lung, spleen and stomach meridians. It has the effect of relieving cold (removing cold from the surface of the muscle), warming and stopping vomiting (treating vomiting caused by stomach cold by warming the spleen and stomach), warming the lungs and stopping cough (stopping cough by warming the lungs), and relieving the toxicity of fishes and crabs, and is commonly used in the treatment of wind-cold cold, stomach-cold vomiting, cold phlegm and cough, and so on. So ginger water can treat cough caused by wind-cold. However, it should be noted that the effect of a single Chinese medicine is weak, and it can be used together with other medicines under the guidance of Chinese medicine practitioners to achieve the best therapeutic effect. Since ginger is slightly warm in nature, it is forbidden to take it for people with yin deficiency and internal heat, so as to avoid aggravating insomnia, palpitations (accelerated heartbeat, often accompanied by panic) and emaciation caused by yin deficiency. If you need to take ginger to treat diseases, it is recommended to consult a doctor.
