Hawthorn is good for eliminating greasy food and helping digestion, and contains an enzyme which can decompose fat and achieve the effect of losing weight. However, it must be fresh hawthorn or dried hawthorn, and processed products such as hawthorn cakes or peel slices contain a lot of sugar and pigments. Only by adding a large amount of saccharin can the sour taste of hawthorn be inhibited, which not only has no weight loss effect, but also may increase weight and have an impact on health.
