Crohn's disease (CD) and ulcerative colitis (UC) are chronic idiopathic inflammatory bowel disorders (IBD) in which patients often require lifelong medication. Poor adherence to medication has been an important barrier to successful management. Understanding patients' beliefs and concerns and addressing physical and perceptual barriers to adherence is crucial in improving adherence.[1] The conventional treatment for IBD involves the use of corticosteroids, immunosuppressants and antitumour necrosis factor (TNF) antibodies. Some of these agents have been associated with the risks of infection and malignancy.[2, 3]
In recent years, complementary and alternative medicine (CAM) is increasingly being used by patients with IBD because of its perceived natural and healthy properties. Population-based and cohort studies have shown that the use of CAM is common among adult and paediatric IBD patients.[4–11] The prevalence of current or past CAM use in adult IBD populations from North America and Europe ranges from 21% to 60%.[5] In a comparative study of Chinese and Caucasian patients, the overall use of CAM was similar in both groups and similar for CD and UC.[12] Younger age, female gender, a higher education level, adverse drug reactions from IBD medication,[7, 8] extra-intestinal manifestations,[4] perceived stress[13] and prolonged and intensive courses of steroids[14] have been associated with the use of CAM in IBD.
CAM products that have been evaluated in clinical studies for the treatment of IBD include herbal medicine, dietary supplementation (probiotics, prebiotics or fish oil), and mind body medicines such as acupuncture, moxibustion or hypnotherapy.[5] Although research has explored many of these products, scientific evidence regarding their efficacy or safety has not been adequate, and the majority of studies have produced inconsistent results.
The aim of this systematic review is to evaluate the efficacy of herbal therapy in the treatment of IBD. We investigated the use of herbal therapy for both the induction and maintenance of disease remission in UC and CD.
