Diabetes mellitus belongs to the category of “consuming thirst” in traditional Chinese medicine, and is often treated with Chinese herbal medicine. Commonly used remedies include consuming thirst formula, Jade Maiden Decoction, and Six-flavored Digoxigenin Pill. Traditional Chinese medicine classifies thirst as upper, middle, and lower consumptions for diagnosis and treatment. 1. Upper Thirst: The treatment is to clear heat and moisten the lungs (to remove heat to moisturize the lungs), and to generate fluids to quench thirst (to promote the production of fluids to alleviate thirst), which is represented by the Thirst Relief Formula. 2. Middle Consumption: The treatment is to clear the stomach and remove the fire (to remove the fire in the stomach), and to nourish yin and increase fluid (to increase the fluid in the body), the representative formula is Jade Maiden Decoction. 3. Lower elimination: the treatment is to nourish yin and consolidate the kidney, the representative formula is Liu Wei Di Huang Wan. The adverse effects of the above formulas are not clear. Jade Maiden Decoction should not be used in patients with loose stools and Yang deficiency in the spleen and stomach. If you are diagnosed with diabetes mellitus, you should go to a regular hospital and choose a suitable treatment plan according to your condition under the guidance of a doctor, rather than self-medication.
