Psyllium Husks- good or bad?

I have been trying psyllium husks since the weekend, taking 1 teaspoon disolved in an 8oz glass of water before I go to bed. Since taking it I feel like a burning/ inflammed feeling in my gut round the ilio cecal area- where all my candida problems seem to be. I have heard some people say that psyllium is too abrasive and causes gut inflammation. However I want to clean out my colon. Perhaps ground flax seeds are a better alternative?
