Are Saaz And Folvite Advisable For Ulcerations On Colon?

Dear Sir, I have been diagnosed with chrons in 2009. Since last one month I have flare up.I got the repeat colonoscopy performed 15 days ago and found multiple small ulceration on ascending cacum and terminal ilium.Doctor prescribed MESACOL 800 Thrice a day along with folivite and raso with no relief.Today he changed my medicine from mesacol to SAAZ DS, folivite and V3L. Kindly suggest if above medicines are ok and if there is any side effect. Thanks Ashwani
