Use 30 grams of garlic, 10 grams of rock sugar, and 200 ml of water. First, boil the water over high heat, then simmer over low heat for a few minutes, boil it into a small bowl, and drink it while it is hot (more is needed) If people drink it together, just boil it in proportion). Drink once in the morning, noon and evening.

Rock sugar has the effect of relieving coughs and reducing phlegm. Adding rock sugar and garlic will enhance the cough-relieving effect, but it is only suitable for coughs caused by wind-cold colds, not suitable for coughs caused by wind-heat colds.
