Soaking mulberry leaves in water has a certain auxiliary effect on diabetes, but it is far from the therapeutic effect. Mulberry leaves contain alkaloids and polysaccharides from mulberry leaves, which can improve islet function and promote insulin secretion. Mulberry leaves are also rich in amino acids, fiber, vitamins and a variety of physiologically active substances, which also have a certain auxiliary effect on lowering blood pressure and blood lipid. However, only by soaking in water, the beneficial components that can be dissolved from mulberry leaves are trace and have no special effect. If you drink it for a long time, it may have some auxiliary effects. If you expect to drink a cup of mulberry leaf tea, your blood sugar and blood pressure will drop immediately, which is almost impossible.
