Drinking lemon in water is a good beauty product because it is extremely rich in vitamins. It can prevent and eliminate skin pigmentation and play a whitening role. Drinking lemon water can also prevent and treat cardiovascular disease, because lemon Water can alleviate the effect of calcium ions on blood coagulation, so it can prevent and assist in the treatment of high blood pressure and myocardial infarction; lemon water contains a large amount of citrate, which can inhibit the crystallization of calcium salts, thereby preventing the formation of kidney stones, and can even prevent some chronic kidney stones. The patient has fewer and fewer stones. Research results announced at the annual meeting of the American Urological Association also show that regular drinking of drinks containing lemon juice can increase the level of citrate in the urine. This chemical can prevent minerals in the urine from forming crystals in the kidneys, which are kidney stones. Lemon is rich in vitamin C, which has many functions such as antibacterial, improving immunity, and assisting in the production of collagen. Drinking lemon water regularly can supplement vitamin C. When you have a cold, drinking 500 to 1000 ml of lemon water a day can relieve runny nose and make the cold go away quickly. Especially when you have just caught a cold, it can be cured without medicine. In addition to being antibacterial and improving immunity, it also has the effects of appetizing, digesting, producing body fluids, quenching thirst, and relieving heat. What is less known is that lemon can also eliminate phlegm, and its effect is stronger than oranges and tangerines. Add lemon juice to warm water and salt and drink it to cough up the thick phlegm accumulated in the throat smoothly. When a cold starts, you might as well drink water with lemon and honey, which can relieve sore throat and reduce discomfort such as dry throat. Cut the lemon into thin slices and soak it in water. It is best to use warm water when soaking, which will help preserve more of the nutrients in the lemon. Of course, you can also add lemon slices when drinking black tea and beverages. It is worth noting that no matter how good the food is, it cannot be eaten unscrupulously. Lemon is no exception. Many women drink a lot of lemon water every day for the sake of beauty and hurt their stomach. Therefore, you should drink lemon water in moderation and should not exceed 1,000 ml per day. In addition, because the pH value of lemon is as low as 2.5, people with hyperacidity and gastric ulcers should not drink lemon water. Be sure to peel it, otherwise it will be prone to pigmentation. The steps and methods mentioned by my friend above are missing two details: 1. After slicing the lemon, remove the seeds (otherwise it will be bitter) and then roll it in white sugar to the extent that each slice is soft. The lemons can no longer produce water; 2. After all the lemons are prepared, put a few large pieces of rock sugar, the fist-sized ones are best. You can also do without single crystal rock sugar. It is better to put the rock sugar in for a few weeks and it will not melt. Add again after melting and stir. And the most important point is that it is best to eat it after one or two years. The lemonade at that time will be dark yellow in color like honey and very viscous. Eating it at that time can clear away heat from the lungs. Steam it with bananas. If you take it, it can relieve heat and cough (you need to soak it in rock sugar). If you take it with formula milk, it can clear away heat. It is better than any fire-clearing treasure you can buy outside. The above is definitely based on experience. Don't be afraid that it will go bad if kept for a long time. Lemon itself has antiseptic properties. What my daughter is drinking now is what I made more than 3 years ago. She has eaten three pounds of lemons for two summers. If you have children and they are still young, I do not agree to use honey. Firstly, it may cause pollen allergies. Secondly, honey is not sweet enough. Can't hold back the sour taste.
