Plant Seed/Oil Has Medical Uses
Flaxseed comes from the flax plant, which grows in the US and Canada. Flaxseed oil comes from grinding the flaxseed. It is also known as linseed oil. Flaxseed is a good source of alpha-linolenic acid (ALA), an essential fatty acid and a precursor to omega-3 fatty acids. Flaxseed is also composed of fiber, which contributes to its laxative effects. The lignans in flaxseed may be responsible for its antioxidant activity. Common uses of flaxseed include as a laxative and as an antioxidant. Evidence of whether or not flaxseed is beneficial in the prevention of heart disease or in the treatment of diabetes is inconclusive. Two or three tablespoonsful of bulk flaxseed may be mixed with water and used as a laxative. Prescription medications should be taken 1 hour before or 2 hours after flaxseed. Flaxseed may increase the risk of bleeding when used with blood thinners. Flaxseed should not be used by women who are pregnant or breastfeeding, and should be discontinued at least 14 days prior to surgery or invasive procedures. Side effects may include diarrhea and constipation (if not used with adequate amounts of water).
