What kind of Chinese medicine does "Acacia" refer to?

Acacia in traditional Chinese medicine is not red beans, so don't mislead others if you don't know. Acacia is a vine, which grows on acacia vines. Red bean trees have white flowers, while acacia vines have red flowers. Although the same size, red beans are flat and heart-shaped, redder and brighter than acacia, and there are no black spots on the pedicle; Like broad beans, acacia seeds are oval, not brighter than red beans, and have black spots on their pedicels. Red beans fall off naturally when they are ripe, while acacia seeds can only be preserved for a long time if they are picked when the pods are just ripe and do not crack. Acacia is the seed of Acacia in Leguminosae. The roots, vines and leaves of this plant can also be used as medicine. Red beans are woody plants that grow on red bean trees. There is a certain difference between the two.
