||Inflammatory bowel diseases (IBD) is a great concern worldwide. New drugs are continuously being developed and combined in order to manage the symptoms and treatment of ulcerative colitis (UC). Moreover, studies show a new approach on plant derived extracts to be used in the treatment of IBD, being less invasive and having less secondary effects. Our aim was to investigate the COX-2 activity level in colonic tissue, through the immunohistochemistry (IHC) technique, and thus prove the anti-inflammatory effect of Thuja occidentalis mother tincture (MT) in oral administration in corresponding doses (5, 25, and 50 mg/kg of body weight). The intra-rectal administration of TNBS resulted in an increase in cyclooxygenase-2 (COX-2) expression in comparison to control. The IHC results showed that the expression of COX-2 inflammatory marker decreased significantly following the oral administration of three doses of T. occidentalis MT (5, 25, and 50 mg/kg of body weight), in dose dependent manner.
