Abstract
Patients studied here suffered from chronic colitis characterized by vague lower abdominal
pain, bleeding per rectum with diarrhoea and palpable tender descending and sigmoid
colon. The inflammatory process in colitis is associated with increased formation
of leukotrienes causing chemotaxis, chemokinesis, synthesis of superoxide radicals
and release of lysosomal enzymes by phagocytes. The key enzyme for leukotriene biosynthesis
is 5-lipoxygenase. Boswellic acids were found to be non-redox, non-competitive specific
inhibitors of the enzyme 5-lipoxygenase. We studied the gum resin of Boswellia serrata for the treatment of this disease. 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 6 weeks) and ten patients were given sulfasalazine
(3 gm daily divided in three doses for 6 weeks) and served as controls. Out of 20
patients treated with Boswellia gum resin 18 patients showed an improvement in one or more of the parameters: including
stool properties, histopathology as well as scanning electron microscopy, besides
haemoglobin, serum iron, calcium, phosphorus, proteins, total leukocytes and eosinophils.
In the control group 6 out of 10 patients showed similar results with the same parameters.
Out of 20 patients treated with Boswellia gum resin 14 went into remission while in case of sulfasalazine remission rate was
4 out of 10. 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.
