Abstract

The invention discloses a black medicine composition with antagonizing inflammatory bowel disease and its application. The percentage is 1% to 99%; the preparation method of the black medicine extract is as follows: adding black medicine decoction pieces into ethanol with a volume concentration of 50-90%, heating and refluxing extraction, and concentrating to obtain; the preparation of the Dendrobium officinale polysaccharide The method is as follows: adding Dendrobium officinale into ethanol, extracting with water and precipitating with alcohol. The composition has the functions of improving the weight loss of enteritis model rats, significantly reducing colonic congestion and edema, intestinal wall expansion and mucosal ulcer damage, reducing intestinal index and intestinal weight per unit length, regulating intestinal immune disorders, inhibiting the expression of intestinal inflammatory mediators, and reducing intestinal inflammation. It can be used to prepare medicines for preventing and treating inflammatory bowel disease.

Description

technical field [0001] The present invention relates to the technical field of traditional Chinese medicines, in particular to a traditional Chinese medicine combination which is composed of herbal extracts and dendrobium polysaccharides and has the ability to significantly antagonize inflammatory bowel disease and its preparation for preventing, improving and treating inflammatory bowel disease. Pharmaceutical applications. Background technique [0002] Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (Ulcerative colitis, UC), is a chronic nonspecific intestinal Inflammatory disease, which can lead to severe deterioration of the patient's biochemical quality, often requiring life-long medication or even surgery. Epidemiological studies have shown that the incidence of IBD is gradually increasing around the world. Its pathogenesis is still unclear, and it is prone to recurrent attacks and difficult to cure. It is also in a state of chr...
