Psyllium, one of the best colon herbs and is used for the colon, colitis, constipation, diverticulitis and hemorrhoids. Psyllium should be taken by itself and not mixed with other combinations. Constipation can result if psyllium is taken at the same time with some combinations. Psyllium HUSKS in their natural state are the most effective in cleansing. CKLS is an excellent alternative when dried herbs in capsules are preferred.
