Plums are plums. Modern medical research shows that ebony contains many natural organic acids, such as citric acid, malic acid, ursolic acid, catechuic acid, tartaric acid, succinic acid, pyruvic acid and acetic acid. The total content is generally 3.0%-6.5%, which is much higher than that of ordinary fruits. Natural organic acids can regulate gastrointestinal function, promote gastrointestinal peristalsis, saliva secretion, help digestion, and improve the antibacterial and bactericidal ability of the stomach, and have the effect of treating diarrhea and constipation.

For example, a large amount of natural citric acid contained in green plum can promote TCA cycle, thus releasing more energy to eliminate fatigue. Malic acid participates in metabolism and energy conversion. The normal operation of metabolism can smoothly decompose various nutrients, promote the absorption and digestion of food nutrients in the human body, and also help to lose weight. Catecholic acid has inhibitory effect on substances causing arteriosclerosis, and has many pharmacological effects such as anti-tumor, anti-oxidation, anti-bacteria, and protection of heart and brain organs.
