If you want to try the herbs I would say go for it. Do not have surgery until you feel you have exhausted all the options you want to exhaust. I went the alternative route too as I was steroid dependent for 2 years. Nothing worked for me so I had surgery after 6mp failed to work (this was in the days when 6mp was the last drug). I can't comment on Remicade although I am glad to not have tried and just to be done with the disease and with the meds, and with the disruption to my life. Life is great post UC. I have never regretted my decision and have been able to do all the activities I missed out on when I had UC.
