Wang, female, 67 years old, suffering from diabetes mellitus for 15 years, coronary heart disease, hypertension 10, 6 years ago appeared numbness and painful coldness in both lower extremities, now treated with insulin, previous insulin dosage 30 units, good glycemic control, in recent years gradually increase the dosage to 60 units per day, blood glucose is still maintained above 10mmol/L, 2 hours after meal blood glucose 15mmol/L, the patient sometimes has chest tightness, weakness, The patient has chest tightness, fatigue, dizziness, insomnia, dark tongue, petechiae on the edge of the tongue, and slippery pulse. The patient was reluctant to increase insulin dosage and sought treatment from a Chinese medicine practitioner, who identified that blood stasis was blocking the ligaments. Prescription: Astragalus membranaceus 30g, Radix Rehmanniae 30g, Eucommiae 10g, Radix Angelicae Sinensis 10g, Radix Paeoniae 15g, Rhizoma Ligustici Chuanxiong 10g, Atractylodes Macrocephalae 10g, Salviae Miltiorrhizae 30g, Radix Puerariae Sinensis 15g, Radix Gastrodiae 30g, Radix Ziziphiopogonis 20g. Take one dose daily with water decoction. After serving for one month, the above-mentioned evidence improved significantly, and the fasting blood glucose was 7 mmol/L, and the blood glucose 2 hours after lunch was 10 mmol/L. The insulin dosage was reduced to 45 units per day, and the formula was kept for 3 months, and the blood glucose basically reached the standard, and the condition was stable. In Chinese medicine, it is said that “the disease enters the lobe for a long time”, and diabetes is developed by the deficiency of both qi and yin, qi is the marshal of blood, blood is the mother of qi, qi deficiency promotes weakness, blood does not run smoothly, slow stagnation, and becomes stasis of blood, which is called “qi deficiency and stasis of blood”. Yin deficiency and fire, decoction of fluids, fluids and blood of the same origin. If there is a deficiency of fluid, the blood becomes thick and stagnant, which is called “Yin deficiency and blood stagnation”. Especially when combined with chronic vascular and neuropathy, oral medications fail or long-term insulin treatment is often accompanied by stasis of blood, such as petechiae on the face, tingling pain in the limbs, pain in the heart area, or numbness in the limbs, or hemiplegia, or low menstrual flow, delayed menstruation, amenorrhea in women, dark tongue, petechiae or petechiae on the edge of the tongue, blue and angry veins under the tongue, etc. Since there is blood stasis, blood circulation should be improved by activating blood circulation and removing blood stasis, and practice has shown that for patients taking long-term oral hypoglycemic drugs and insulin injections, or patients with chronic complications, the application of treatment to activate blood circulation and remove blood stasis can often make some of the patients’ hypoglycemic drugs and insulin injections more effective. It has been proved that for patients on long-term oral hypoglycemic drugs and insulin injections, or patients with chronic complications, the application of blood circulation and blood stasis treatment can often reduce the dosage of hypoglycemic drugs and insulin in some patients, while the condition is still under satisfactory control. Clinical studies have shown that the representative formula for clearing heat and detoxifying the toxin, Huang Lian Detoxification Tang, can lower glucose, lower lipids and improve insulin resistance. Chinese medicine to reduce sugar is not limited to one method, the previously introduced benefits of Qi and Yin, laxative, blood circulation and detoxification can regulate blood sugar. Chinese medicine is often a comprehensive analysis of age, constitution, symptoms, complications, tongue and pulse, to identify the internal organs (lung, spleen, stomach, liver, kidney), Yin and Yang deficiency, to supplement the deficiency and diarrhea, to regulate the qi, blood, Yin and Yang, although not directly lowering sugar, but ultimately play a role in lowering sugar, which is perhaps the wonderful thing about Chinese medicine.
