“Mulberry leaf tea can lower blood sugar” is false. Mulberry leaves contain an alkaloid that may assist in lowering blood sugar, but mulberry leaf tea is not a substitute for medication to lower blood sugar treatment. Mulberry leaves are rich in amino acids, fiber, vitamins, minerals and a variety of active substances, which contains an alkaloid, may assist in lowering blood sugar. Mulberry leaf tea is not a substitute for hypoglycemic drugs to lower blood sugar treatment, patients with diabetes need to take metformin, acarbose and other oral hypoglycemic drugs or insulin injection and other medications based on dietary control and physical exercise. Patients diagnosed with diabetes should standardize their treatment under the guidance of a doctor.
