Diabetes is a common chronic condition that significantly impacts daily life—especially diet. Can individuals with diabetes consume Ophiopogon japonicus (Maidong) and Rehmannia glutinosa (Shengdi)?

Can individuals with diabetes consume Maidong and Shengdi?

Yes, individuals with diabetes may consume Maidong and Shengdi—preferably when blood glucose levels are well-controlled. During winter, dry weather causes the body to lose substantial moisture. People with diabetes urinate more frequently than healthy individuals and thus must pay special attention to maintaining adequate hydration. Maidong has been shown to promote pancreatic β-cell function recovery, increase hepatic glycogen storage, and lower blood glucose levels; it is therefore commonly included in traditional Chinese herbal formulas for diabetes management. Elevated blood glucose levels in diabetic patients lead to polyuria, which exacerbates symptoms such as thirst. To address this, in addition to increasing water intake, moderate consumption of Maidong may be beneficial. According to Traditional Chinese Medicine (TCM), Maidong nourishes yin, generates body fluids, clears heat from the heart and lungs, calms irritability, clears heat from the stomach and intestines, and moistens the lungs to relieve cough and dryness.

Dietary control remains essential for people with diabetes. Many patients report hunger and dizziness, but it is recommended to follow evidence-based Western medical guidance: monitor blood glucose regularly and adjust food intake accordingly, while also incorporating appropriate physical activity. Regarding dietary therapy, emphasis should be placed on consuming abundant vegetables—particularly Chinese cabbage. Generally speaking, these foods contain negligible fat and protein, and their carbohydrate content provides minimal caloric energy; thus, high-fiber foods primarily serve to promote gastric satiety.

Patients should monitor and manage their blood glucose levels daily. We hope this information proves helpful. Wishing you good health and a joyful life!
