Garlic water is still effective in treating coughs. Garlic is white in color and enters the lungs and is pungent and warm in nature, which is most suitable for getting rid of wind evils in the lung meridian. It is often particularly effective for treating coughs accompanied by an itchy throat. You can boil garlic with rock sugar and drink it, which is much better than injections and medication for treating coughs with colds. The method is to use 30g of garlic, 10g of rock sugar, add 200ml of water, first boil the water on high heat, then simmer it slowly for a few minutes on low heat, and finally boil it down to a small bowl amount and drink it while it is still hot. When the cough is more severe, you need to take it 3 times in 1 day, and you can see the effect on the 2nd day, basically in 3 days. If the cough is more severe with more white thin sputum, you can add ginger to the ice sugar and garlic water to boil it, and the effect will be better.
