Description

Technical Field

[0001] The present invention relates to the technical field of health care products, and in particular to a medicine-food homologous auxiliary blood sugar-lowering health care food and a preparation method thereof. Background Art

[0002] Diabetes is a group of metabolic diseases characterized by high blood sugar. Long-term high blood sugar can cause chronic damage and dysfunction of various tissues, especially the eyes, kidneys, heart, blood vessels, and nerves. With the improvement of people's living standards, changes in dietary structure and lifestyle, the incidence of diabetes is increasing year by year around the world.

[0003] At present, chemical drugs, such as insulin, sulfonylureas, and biguanides, are mainly used to treat diabetes clinically. Although these drugs can control blood sugar to a certain extent, they also have some shortcomings. For example, insulin needs to be injected, which brings inconvenience and pain to patients; sulfonylureas and biguanides may cause side effects such as hypoglycemia, gastrointestinal discomfort, and liver and kidney damage. In addition, long-term use of chemical drugs may also cause patients to develop drug resistance and reduce the treatment effect.

[0004] In order to find safer and more effective treatment methods, people began to pay attention to natural products that are both medicine and food. Medicine and food are both medicines, and there is no absolute dividing line between them. Some natural medicine and food substances have the effect of regulating blood sugar, and are highly safe and have few side effects. For example, bitter melon contains ingredients such as bitter melon glycosides and polypeptide-P, which have the effects of lowering blood sugar, lowering blood lipids, and anti-oxidation; mulberry leaves contain alkaloids, flavonoids, polysaccharides and other ingredients, which can inhibit the activity of α-glucosidase and lower blood sugar; yam contains mucin and diosgenin, which can regulate blood sugar and enhance immunity; kudzu root contains puerarin and soybean glycosides, which have the effects of lowering blood sugar and improving microcirculation; cinnamon contains cinnamaldehyde, cinnamic acid and other ingredients, which can enhance insulin sensitivity and lower blood sugar.

[0005] However, the current products of medicine and food for auxiliary hypoglycemic treatment on the market have the following problems: first, the product types are single, and most products contain only one or several medicine and food ingredients, with limited hypoglycemic effect; second, the product quality is uneven, and some products have low content of active ingredients, and even counterfeit and inferior products; third, the preparation method of the product is not scientific enough, resulting in low extraction rate of active ingredients, affecting the efficacy of the product. Therefore, it is of great practical significance to develop an auxiliary hypoglycemic health product composed of multiple medicine and food ingredients, with reliable quality and scientific preparation method.

[0026] A preparation method of a medicine-food homologous auxiliary blood sugar-lowering health product, the specific preparation method is as follows:

[0027] (1) mixing bitter melon extract, mulberry leaf extract, yam extract, kudzu root extract, cinnamon extract, bamboo leaf extract, wolfberry extract and astragalus extract according to the above weight parts;

[0028] (2) adding an appropriate amount of auxiliary materials, such as starch, dextrin, and microcrystalline cellulose, to the mixed extract to prepare granules;

[0029] (3) After the granules are dried, they are put into capsules or compressed into tablets to obtain the medicine-food auxiliary blood sugar-lowering health product of the present invention.

[0030] The principle of the above formula is:

[0031] Bitter melon: It is a plant of the Cucurbitaceae family. Modern pharmacological research has shown that bitter melon has a significant effect in lowering blood sugar.

[0032] Mulberry leaf: It is a plant of the Moraceae family. Mulberry leaf is cold in nature, sweet and bitter in taste, and enters the lung meridian. It has the effects of dispersing wind-heat, clearing away dryness, and clearing the liver and improving eyesight. Modern pharmacological studies have shown that active ingredients such as total polysaccharides and total flavonoids in mulberry leaves have a blood sugar-lowering effect.

[0033] Yam: The tuber is rich in starch and can be eaten as a vegetable; it can be used as medicine to replenish the spleen and stomach, treat qi deficiency and weakness, indigestion, spermatorrhea, enuresis and unknown swelling and toxins, etc.

[0034] Pueraria root: It is the dried root of the leguminous plant Pueraria lobata, commonly known as wild kudzu. It is dug in autumn and winter, cut into thick slices or small pieces while fresh; dried. It is sweet, spicy, and cool. It has the functions of relieving muscle and fever, clearing rashes, promoting body fluid and quenching thirst, and raising yang and stopping diarrhea. It is often used for fever due to superficial symptoms, stiff neck and back pain, measles that does not clear up, thirst due to febrile diseases, thirst due to yin deficiency, hot diarrhea and dysentery, and diarrhea due to spleen deficiency.

[0035] Cinnamon: Cinnamon is a hot and pure yang product. It can warm and nourish the fire of the gate of life, suppress yang and eliminate yin. It can be used for the condition of insufficient kidney yang and weak fire of the gate of life, such as chills, cold limbs, weak waist and knees, impotence and frequent urination. It can also be used for cold pain in the abdomen, poor appetite and loose stools caused by spleen and kidney yang deficiency. Adding cinnamon to the daily diet in moderation may help prevent or delay type 2 diabetes caused by aging. Cinnamon can reactivate the ability of fat cells to respond to insulin and greatly accelerate the metabolism of glucose, which may play a preventive role in type 2 diabetes.

[0036] Bamboo leaves: a plant of the Gramineae family. According to traditional Chinese medicine, bamboo leaves are bitter and cold, and enter the heart and kidney meridians. They have the functions of sweet and mild purgation, cold and clearing, and stopping thirst. Modern pharmacological studies have shown that flavonoid compounds and bioactive polysaccharides in bamboo leaves have immune regulation and blood sugar lowering effects.

[0037] Wolfberry: Wolfberry has been a top-grade tonic since ancient times, and has the effect of delaying aging, so it is also known as "quelaozi". The vitamin C content in wolfberry is higher than that in oranges, the β-carotene content is higher than that in carrots, and the iron content is higher than that in steaks; the aphrodisiac function of wolfberry is unexpected; for women, eating wolfberry regularly can also have the effect of whitening and nourishing the skin; wolfberry is sweet and flat in nature, belongs to the liver and kidney meridians, has the effect of nourishing the liver and kidney, nourishing the liver and improving eyesight, and is often used with cooked rehmannia, chrysanthemum, yam, cornus fruit and other medicines; wolfberry is a treasure from head to toe, wolfberry can replenish deficiency and produce essence, and is used as medicine or to make tea, wine, and stew soup. If you can drink it regularly, you can strengthen your body; wolfberry has a significant inhibitory effect on in vitro cancer cells, and can be used to prevent the spread of cancer cells and enhance the body's immune function.

[0038] Astragalus: It is the root of Astragalus mongolica or Astragalus membranaceus, a plant of the Leguminosae family. According to Chinese medicine, Astragalus is sweet and slightly warm in nature. It enters the lung, spleen, liver and kidney meridians, and has the effects of invigorating qi and strengthening the exterior, restraining sweat and preventing dehydration, and promoting diuresis and reducing swelling. It is used to treat qi deficiency and fatigue, narrowing of the middle qi, internal heat and thirst, nephritis proteinuria, diabetes, etc. Modern pharmacological studies have shown that Astragalus can increase the activity of glycogen synthase and improve insulin sensitivity, thereby playing a role in lowering blood sugar.

[0039] The combination of the above-mentioned medicines can not only clear the lungs and moisten dryness, purge fire and quench thirst, treat deficiency and strengthen the body, replenish fire and assist yang, improve digestion, but also invigorate qi and lower blood sugar. Therefore, it has a good therapeutic and health-care effect on the thirst syndrome of qi and yin damage caused by lung dryness and stomach heat.

[0040] Beneficial effects of the present invention:
