Ulcerative colitis is a chronic idiopathic inflammatory bowel disease with a relapsing nature. It is a very challenging disease affecting a patient during the most active period of his life i.e. 20 to 40 years of age. The main features are ano-rectal bleeding with increased frequency of bowel evacuation, general debility and with abnormal structural pathology in the descending colon, particularly sigmoid colon. In modern medical science, there is no permanent curative and safe treatment for this disease. This study can be helpful for reducing the need of steroids and surgical processes in the patients of ulcerative colitis. A clinical study of 43 patients of ulcerative colitis has been conducted at the O.P.D. (outdoor patient department) and I.P.D. (indoor patient department) of the P D Patel Ayurveda Hospital, Nadiad. They were given Udumbara kvatha basti with oral Ayurveda medicaments including Kutaj ghan vati, Udumbara kvatha, and combination of Musta, Nagakesara, Lodhra, Mukta panchamrut rasa for a one-month period. Results were analyzed statistically by using the 't' test. In this study, it was observed that the symptoms and signs, daily dose of steroids and other anti-inflammatory drugs were reduced by more than 75% with a highly significant result. The hemoglobin level was also increased.
