Lotus leaf tea does not provide a therapeutic effect of lowering blood sugar. Lotus leaf tea is a tea made from lotus leaves, which has the effect of clearing heart fire and calming liver fire. No research has shown that lotus leaf tea can lower blood glucose concentration, so lotus leaf tea can not play a therapeutic effect of lowering blood glucose. People who need to lower blood sugar can be treated with oral hypoglycemic drugs, such as metformin, or injections such as insulin and other injectable preparations, which need to be combined with physical exercise and dietary management to help promote the lowering of blood sugar. People with high blood sugar should be treated under the guidance of a doctor, and drinking lotus leaf tea alone will not have a therapeutic effect, and scientific treatment needs to be followed.
