Just soak 2-3 slices of dried lemon in water. The main difference between dried lemon slices and fresh lemon slices is the amount of trace elements contained.
Lemon is best soaked in warm water, because vitamin C is easy to die at high temperature, and if it can't be soaked in a thermos for a long time, some toxic qualities in plants will be soaked out. Lemon contains a lot of vitamin C, which is easily oxidized. The vitamin C content of dried lemon slices is definitely lower than that of fresh ones. The taste of water will be slightly worse, but the difference is not very big. If you soak in water, there is little difference in efficacy.
Soaking dried lemon slices in water can also whiten the skin. Drying lemon slices will only evaporate water and a few ingredients, while most of them will remain. But the whitening effect of dried lemon slices soaked in water is not as good as that of fresh lemon slices. The nutritional components of dried lemon slices are still slightly worse than fresh ones, and the absorption is not as good as fresh ones.
Extended data:
Precautions for lemon slices: Please keep them indoors in a cool and dry place to prevent children from taking them by themselves. It is worth noting that even the best food can't be eaten recklessly. Lemon is no exception. Many women drink a lot of lemonade every day for beauty, which hurts their stomachs. So drink lemonade in moderation, not more than 1000 ml per day. In addition, because the pH value of lemon is as low as 2.5, people with hyperacidity and gastric ulcer should not drink lemonade.
Suitable for matching: it can be matched with any scented tea.
Note: It is best not to drink lemon slice tea overnight, because drinking tea overnight may cause gastrointestinal discomfort.
