Floralax Laxative Powder by Flora Inc 7oz. Powder Floralax Laxative Powder 7oz. Powder Product is a unique laxative formula with three natural sources of high quality fiber rolled into one organic flax seeds psyllium husks and organic oat bran. The primary ingredient in Flora Lax is psyllium husks because they contain 60 to 70 soluble fiber more than eight times that of oat bran. When ingested with the proper amount of water psyllium can swell up to 100 times its original volume providing bulk to fecal mass. In this bulk form psyllium acts as a sponge that absorbs intestinal toxins and helps maintain healthy blood cholesterol levels. It moves quickly through the colon because it has a lubricant action equal to that of oil but is not oily. It contains no nutrients. These husks are almost tasteless and they are a good choice for those with an aversion to oily supplements. Defatted flax seeds are used because they swell up with water and form mucilage which keeps fecal matter soft.
