What is Flax?


Know the basics

What is Flax used for?

People use flaxseed for many conditions related to the gastrointestinal (GI) tract, including ongoing constipation, colon damage due to overuse of laxatives, diarrhea, inflammation of the lining of the large intestine (diverticulitis), irritable bowel syndrome (IBS) or irritable colon, sores in the lining of the large intestine (ulcerative colitis), inflammation of the lining of the stomach (gastritis), and inflammation of the small intestine (enteritis).

Flaxseed is also used for disorders of the heart and blood vessels, including high cholesterol, “hardening of the arteries” (atherosclerosis), high blood pressure (hypertension), and coronary artery disease.

Flaxseed is also used for acne, attention deficit-hyperactivity disorder (ADHD), kidney problems in people with a disease called systemic lupus erythematosus (SLE), symptoms of menopause, and breast pain. It is also used for diabetes, obesity and weight loss, HIV/AIDS, depression, bladder infections, malaria, and rheumatoid arthritis.

Other uses include treatment of sore throat, upper respiratory tract infections (URTI), and cough.

Some people use flaxseed to lower their risk of getting weak bones (osteoporosis) and to protect against breast cancer, lung cancer, colon cancer, and prostate cancer.

How does it work?

There are not enough studies about how this herbal supplement works. Please discuss with your herbalist or doctor for more information. However, there are some studies that show anticancer action might be from a high intake of equol, one of the flavone components, and enterolactone, a substance formed by the breakdown of flax.

Flaxseed is a good source of dietary fiber and omega-3 fatty acids. The fiber in flaxseed is found primarily in the seed coat. Taken before a meal, flaxseed fiber seems to make people feel less hungry.

Know the precautions & warnings

What should I know before using Flax?

Refrigerate flax products to prevent fatty acid breakdown.

Raw or unripe flaxseed is possibly unsafe. Flaxseed in these forms is thought to be poisonous.

Monitor for hypersensitivity and overdose reactions. If present, discontinue use of this herb and administer an antihistamine or other appropriate therapy.

Flaxseed can lower blood sugar levels and might increase the blood sugar-lowering effects of some medicines used for diabetes. If you have diabetes and use flaxseed, monitor your blood sugar levels closely.

Because flaxseed might act somewhat like the hormone estrogen, it can make some hormone-sensitive conditions worse. Some of these conditions include breast, uterine, and ovarian cancer; endometriosis; and uterine fibroids.

Flaxseeds might lower diastolic blood pressure. Theoretically, taking flaxseeds might cause blood pressure to become too low in individuals with low blood pressure.

The regulations for an herbal supplement are less strict than the regulations for a drug. More studies are needed to determine its safety. The benefits of taking this herbal supplement must outweigh the risks before use. Consult with your herbalist or doctor for more information.
