Flaxseed and its derivative
flaxseed oil/linseed oil are rich sources of the essential fatty acid alpha-linolenic acid, which is a biologic precursor
to omega-3 fatty acids such as eicosapentaenoic acid. Although omega-3 fatty acids have been associated with improved cardiovascular
outcomes, evidence from human trials is mixed regarding the efficacy of flaxseed products for coronary artery disease or hyperlipidemia. Flaxseed oil contains only the alpha-linolenic acid component of flaxseed, and not the fiber or lignan components. Therefore,
flaxseed oil may share the purported lipid-lowering properties of flaxseed, but not the proposed laxative or anti-cancer abilities.
Expert Opinion and Historic Precedent:
Flaxseed
products are used widely for numerous indications. The Commission E, has sanctioned the use of flax for chronic constipation,
laxative-damaged colons, irritable bowel, diverticulitis, and enteritis.
