Sour plum soup is one yuan per cup

Sour plum soup is a traditional summer drink in old Beijing. In the hot season, most people will buy ebony to cook it themselves (or use red bayberry instead of ebony), put some sugar in it to remove the acid, and drink it after cooling. The raw materials of sour plum soup are ebony, hawthorn, osmanthus, licorice and rock sugar. "Compendium of Materia Medica" says: "Those who pick semi-yellow in Mei Shi use smoked plum." It can remove heat and send cold, relieve pain, and even cure cough, cholera and dysentery. The fairy tale "Legend of the White Snake" wrote the story of the epidemic in Wumei. The soup has the functions of promoting digestion, removing blood stasis, promoting fluid production, quenching thirst, astringing lung qi, relieving restlessness and calming the nerves. Regular drinking can really get rid of diseases, protect health and strengthen the body. It is a rare health drink in hot summer.
