Description
Technical Field
The invention relates to a traditional Chinese medicine composition, in particular to a traditional Chinese medicine composition for preventing and treating hyperuricemia and a preparation method and application thereof.
background
Hyperuricemia is a metabolic syndrome caused by long-term purine metabolic disorder or reduced uric acid excretion, is the most important biochemical basis for gout development, and is the second major metabolic disease following diabetes mellitus, and the incidence rate is high. The division of endocrinology of the Chinese medical society in 2013 in the Chinese expert consensus on hyperuricemia and gout treatment indicates that the incidence of hyperuricemia in China is rising year by year, and particularly, the prevalence of hyperuricemia reaches 5% -23.5% in economically developed cities and coastal areas, and is close to the level of developed countries in the West.
The traditional medicines for treating hyperuricemia at present are western medicines such as allopurinol, benzbromarone and the like, although the effect of reducing the blood uric acid is rapid, the traditional medicines have large toxic and side effects on the liver and the kidney, and cannot be taken for a long time. The market has more health care products with the function of reducing blood uric acid, but few health care products capable of effectively preventing and treating hyperuricemia are available, and the main measures for preventing and treating hyperuricemia of patients with hyperuricemia are still western medicines.
The traditional Chinese medicine considers that the viscera dysfunction and the abnormal transportation and transformation of qi, blood and semen are caused. The spleen fails to transport and transform, and phlegm-turbidity is generated internally, which is transformed from heat to damp-heat phlegm-turbidity internally (excessive production of uric acid in blood); if the liver fails to regulate and defecate, the kidney governs the function of the stool, the excretion of turbid phlegm-damp heat is slow or reduced (the excretion of uric acid in blood is reduced), so that damp-heat phlegm-turbid is accumulated in the interior. In conclusion, the main pathogenesis of the disease is dysfunction of the zang-fu organs and accumulation of damp-heat and phlegm-turbid.
According to the requirements of people suffering from hyperuricemia and the advantages of the traditional Chinese medicine in treating and preventing hyperuricemia, the invention selects a medicinal and edible raw material formula disclosed by the Ministry of health according to the traditional Chinese medicine and traditional Chinese medicine principles and the pathogenesis of hyperuricemia, and is used for preparing functional health-care food or medicine for preventing and treating hyperuricemia.

The technical scheme is as follows: in order to achieve the above purpose, the invention adopts the technical scheme that:
A traditional Chinese medicine composition for preventing and treating hyperuricemia comprises the following raw materials in parts by weight: 1-6 parts of plantain herb, 1-6 parts of purslane, 1-4 parts of glabrous greenbrier rhizome and 1-4 parts of coix seed.
As a preferred scheme, the traditional Chinese medicine composition for preventing and treating hyperuricemia comprises the following raw materials in parts by weight: 6 parts of purslane, 5 parts of plantain herb, 4 parts of glabrous greenbrier rhizome and 4 parts of coix seed.
The traditional Chinese medicine composition for preventing and treating hyperuricemia is applied to preparation of medicines or health-care products for preventing and treating hyperuricemia.
The preparation method of the traditional Chinese medicine composition for preventing and treating hyperuricemia comprises the following steps:
According to the weight portion, the plantain herb, the purslane, the glabrous greenbrier rhizome and the coix seed are extracted for 1 to 3 times, each time lasts for 0.5 to 3 hours, extracting solutions are combined and concentrated to obtain a concentrate, and then the concentrate is prepared into a pharmaceutical preparation with a pharmaceutically acceptable carrier or a health-care product with a food additive.

Preferably, the preparation method of the traditional Chinese medicine composition for preventing and treating hyperuricemia comprises the steps of tablets, pastilles, capsules, solutions, syrups, suspensions or injections.
The present invention recognizes that hyperuricemia is a disease caused by increased uric acid synthesis or decreased uric acid excretion. The spleen fails to transport and transform, resulting in phlegm-turbidity which is transformed from heat to damp-heat, resulting in excessive production of uric acid. When the liver fails to regulate and defecate, the kidney governs the function of stool, the turbid phlegm-dampness-heat will be slowly excreted or the excretion of uric acid in blood will be reduced. Therefore, the accumulation of damp-heat phlegm-turbidity is the pathological mechanism of the disease, and the main treatment method for treating hyperuricemia of the invention is tonifying spleen and kidney, clearing heat, promoting diuresis and discharging turbidity. Therefore, the invention selects the raw material formula with dual purposes of medicine and food, namely plantain herb, purslane, glabrous greenbrier rhizome and coix seed. Wherein, the plantain herb in the formula is sweet and cold, enters liver, kidney, lung and small intestine channels, clears heat and promotes diuresis, eliminates phlegm, cools blood and detoxifies, so the plantain herb is a monarch drug; the purslane is sour and cold, enters liver and large intestine channels, and is used as a ministerial drug for clearing heat and removing toxicity; coix seed, semen Coicis, sweet, bland and cool, enters spleen, stomach and lung meridians, has the effects of promoting diuresis, eliminating dampness, invigorating spleen, relieving diarrhea, eliminating arthralgia, expelling pus, removing toxic substance and resolving hard mass. Smilax glabra L.has sweet, bland and mild properties, enters liver and stomach meridians, and has the actions of removing toxicity, removing dampness and easing joint movement, so both of them have the action of promoting water and excreting dampness, so they are used as guiding drugs. In the recipe, plantain herb promotes diuresis, removes dampness, clears heat and promotes urination, purslane clears away heat and toxic materials, and coix seed and glabrous greenbrier rhizome promote diuresis, remove dampness, clear away heat and toxic materials. The formula can promote diuresis and eliminate dampness, and clear away heat and toxic materials, so that the effects of tonifying spleen and kidney, clearing away heat, promoting diuresis and discharging turbidity, treating both symptoms and root causes, and preventing and treating hyperuricemia for a long time can be achieved.
