The seeds are very mucilaginous and are used with great success in pulmonary (lung) conditions such as bronchitis, asthma, pleurisy or any inflammatory mucous membrane condition. They are good for urinary complaints, as they are lubricating and very soothing. In bronchitis with a lot of catarrh, they can help in the expectoration of mucous and have a relaxing effect on the bronchioles.

The seeds are extremely high in soluble fibre (mucilage) and are very effective as a laxative that does not gripe too much (cause bowel pains) and is used for a sluggish or torpid liver. The soluble fibre in the seeds has been shown to significantly lower LDL (bad) cholesterol levels.

Applied externally, flax seeds are used for chest complaints, boils, abcesses, burns and ulcers.

The oil made from the seeds contains linoleic and alpha-linolenic essential fatty acids (EFAs). EFAs produce hormone-like prostaglandins that are vital for many functions of the body. They help such conditions as skin disorders, menstrual problems, rheumatoid arthritis and arteriosclerosis. The EFAs help prevent buildup of fatty deposits in the tissues and are a great source of cancer-fighting isoflavones. For more information, see Food Supplements -- Essential Fatty Acids.
