Flax seed may not be the best choice for use on the skin but has tremendous benefit when taken internally. It has been shown to be beneficial for those who have Crohn's disease and Colitis. It seems to sooth inflamed intestinal lining and it has a natural laxative effect because of its high fiber content.
One precaution associated with flax seed oil is that it may slow the absorption rate of oral medications or other nutrients taken at the same time.
