Ulcerative colitis (UC) is a common, relapsing inflammatory bowel disease (IBD) presenting with ulcers and wounds located on the colonic intestinal mucosa. The difference between ulcerative colitis and Crohn’s disease is that ulcerative colitis is located on the colon and wounds are limited to the superficial mucosal membranes of intestinal lumen. The main pathological feature of disease is inflammatory destruction of inner layer of the colon lumen. The disease is clinically presented with rectal bleeding, abdominal pain and diarrhea. Even though there are different hypotheses about the aethiopathogenesis of disease, the exact causes of UC are currently unknown 1.

Inflammatory response and formation of cytokines result in an increase in radicals, reactive oxygen species (ROS) and reactive nitrogen species (RNS) in UC patients. The integrity of the mucosal membrane is erupted with enormous amounts of radicals, ROS, RNS, enzymes and cytokine formation 2–42–42–4. According to scientific evidence, in long term UC patients an increase in epithelial dysplasia and cancer complications has been noted 3. Secondary metabolites in Matricaria chamomilla (MC) have both anti-inflammatory and anti-oxidant radical scavenging properties and in our study, we investigated this plant’s protective effect on mucosal layer integrity 5.

In this study we examined the protective and complementary effects of MC. The grounded theory of choosing MC depends on anti-oxidant and anti-inflammatory effects of phenolic, flavonoidal secondary metabolites which are greatly found in herba of this plant 6.

Destruction of mucosal layer and induction of colitis and formation of inflammatory response was triggered by application of tri-nitro bezene sulphonic acid (TNBS) through the rectum. Methanol extract of drug was applied to UC-induced rats by oral gavage 7.

In-vitro examination of the anti-oxidant profile of methanol extract of MC has been evaluated by 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid), 2,2-diphenyl-1-picrylhydrazyl free radical scavenging and CUPRAC methods 8,98,9. After administration of MC extracts, blood samples were drawn and analysis of total oxidative stress and total anti-oxidative stress assays was performed 10–1310–1310–1310–13. Histological investigation of bowel specimens has also been compared with a control group.
