Garlic rosewater has an obvious effect on coughs. Garlic has antiseptic and disinfectant properties, and is particularly effective for coughs caused by inflammation. In addition, when garlic is used to make rock sugar water, it also has some cough-suppressing and phlegm-relieving effects as well as lung-moistening effects. We all know that rock sugar has the effect of moistening the lungs, so garlic rock sugar water is good for cough. Generally, you can take 30 grams of garlic and 10 grams of rock sugar, then add two large bowls of water and boil for about ten minutes, and drink a small bowl of water while it is still hot. If the cough is serious, you can take it 3 times a day. It is best to crush the garlic before boiling to make the water, for better results. In addition, if garlic iced sugar water is not very effective in treating cough, it is necessary to go to the hospital for a specific examination, and according to the cause of the cough, it is more scientific to carry out effective treatment for the cause, and not to rely on garlic iced sugar water to treat the cough condition.
