Plum blossoms are mainly for viewing. Mume fruits are mainly used for processing or medicine, and are generally processed into various preserves and jams;
Mume, processed from green plum, is used as astringent, which can cure dysentery, relieve cough, eliminate phlegm, relieve fever and kill insects. It is also the raw material for extracting citric acid.
Bud can stimulate appetite, dispel depression, promote fluid production, eliminate phlegm, promote blood circulation and detoxify; Grinding roots into powder is effective in treating jaundice. This plant is sensitive to hydrogen fluoride pollution and can be used to monitor fluoride pollution in the atmosphere.
Immature fruit contains citric acid, malic acid, succinic acid and so on. Seeds contain amygdalin; Flowers contain volatile oil, and oil contains benzaldehyde, benzoic acid and so on.

Plum is native to southern China and has been cultivated for more than 3000 years. There are many varieties of plum, whether it is ornamental or fruit trees. Many types are not only cultivated in the open field for viewing, but also planted as potted flowers to make plum piles. Flowers can be refined, and flowers, leaves, roots and seeds can be used as medicine. The fruit can be eaten, pickled or processed into Senecio scandens, or smoked into ebony, which has the effects of relieving cough, stopping diarrhea, promoting fluid production and quenching thirst. Plum blossom can resist the harm of root-knot nematodes and can be used as the rootstock of drupe fruit trees.
