Is brewed sour plum drink harmful to the body?

Generally, brewed plum juice (sour plum drink) is harmless to the human body, but excessive consumption should be avoided as it may lead to certain adverse reactions.
Plum juice is a common summer beverage. It contains abundant citric acid, fruit acid, and malic acid, which not only aid digestion and relieve fatigue but also help replenish nutrients, prevent heatstroke, and consolidate lung qi. Brewed plum juice is safe to drink and poses no harm to the body. However, it is best prepared with hot water, with an appropriate amount of honey added, then cooled before drinking for improved taste.
Plum juice contains large amounts of organic acids that can stimulate gastric juice secretion. Drinking too much may cause symptoms such as heartburn, stomach pain, or diarrhea. Additionally, women who consume excessive amounts during menstruation may experience worsened menstrual cramps. Therefore, plum juice should be consumed in moderation. In daily life, one can stay cool by eating fresh fruits such as watermelon, pineapple, and strawberries, which also help replenish essential nutrients and benefit overall health.
