Black beans are among the most nutritious beans of all. They are rich in anthocyanins, vitamins, and trace elements such as zinc, copper, and magnesium, which are especially valuable for mothers after childbirth. Black beans can resist aging, accelerate metabolism, eliminate edema, and promote milk secretion, helping to relieve back pain after childbirth. The production process consumes a lot of energy, and black beans nourish the kidneys and bones, helping recovery.
 As a health drink, black bean tea is loved by mothers. It nourishes the spleen, kidney and liver, and improves frequent urination, dizziness, blurred vision, premature graying of hair, leg cramps and back pain. Menopausal women drinking black bean roasted rice tea can relieve sweating and sleep problems caused by lack of estrogen.
