Lemon water is rich in vitamins C, can prevent and eliminate skin pigmentation, and play a whitening role. At the same time, lemon water can also relieve the effect of calcium ions to promote blood coagulation, and can prevent and assist in the treatment of hypertension and myocardial infarction. Because the pH of lemons is as low as 2.5, people with hyperacidity and gastric ulcers should not drink lemonade.
