Diabetes is a series of functional diseases as well as clinical symptoms caused by digestive system disorders. We should pay attention to abandoning the saying of lowering sugar in the clinical evidence, accurately diagnose the disease mechanism, prescribe the right medicine for the evidence, and the blood sugar will naturally drop when the disease is receded, and the treatment effect is more significant. Therefore, it is believed that diabetes is actually a digestive system disease, where glucose has not been effectively converted for a long time, or has not been treated in the correct way, and is a glucose energy deficiency. The energy material to maintain life activities depends on glucose and trace elements in the acquired food intake. When the heat energy of the organs is insufficient or the digestive system has functional disorders, the glucose and trace elements in the ingested food are difficult to be absorbed or digested, and the energy is lost or retained in the blood, so that the function of each organ is malfunctioned because of the lack of glucose energy supply, thus causing the disease. For example, diabetic rotten feet, if we take the rule of replenishing Qi, we can use many methods, such as topical glucose powder or marshmallow, monosaccharide or polysaccharide food, if there are fresh leaves of the stevia plant pounded and put on the outside can also be. Usually I use calcined plaster and cotton candy or glucose powder to distribute a good proportion of bottled, when used can be taken to the patient at any time, sprinkled on the wound or put on it, the light once a day change, serious twice a day change, soon healing. No need for any medicine, just use sugar to put on it, it will soon get energy supply and it will heal. Thus, it is well proven that the spleen and pancreas like sweet food. It is known that the spleen is the master of the limbs and the spleen is the master of transportation. When the body is completely lacking in glucose energy, the spleen and pancreas are in a state of starvation and have no ability to promote the operation of qi, blood and energy, and even less ability to push to the end of the limbs for nutrition, resulting in the rotten foot of diabetes not being healed.
