In this 2001 clinical trial, Gupta and his colleagues studied the effects of gum resin of Boswellia serrata in patients with chronic colitis. Thirty patients, 17 males and 13 females in the age range of 18 to 48 years with chronic colitis were included in this study. Twenty patients were given a preparation of the gum resin of Boswellia serrata (900 mg daily divided in three doses for six weeks.) In conclusion, this study shows that a gum resin preparation from Boswellia serrata could be effective in the treatment of chronic colitis with minimal side effects.
