Garlic and rock sugar are clinically used for coughs caused by wind-cold colds because garlic itself has a strong antiseptic effect and is rich in the natural antibacterial factor allicin, while rock sugar has the effect of moistening the lungs, relieving cough and resolving phlegm. However, it is clinically indicated mainly for coughs caused by wind-cold colds, and is not suitable for coughs caused by wind-heat colds. Other ingredients can also be added in clinical practice, such as red dates and ginger slices cooked together can further remove cold and promote lung, which can play a better role in the treatment of wind-cold colds.
