General
Description: It is a small or medium-sized tree
with a rounded crown and horizontal or drooping branches.
The leaves are dark green, shining, elliptic to obovate.
Fruits are ovoid, 2 inches in dia., yellow or red when
ripe, with 6-8 grooves. Seeds are 6-8 surrounded by
a succulent aril.
Traditional uses:
Flax is an erect, herb, cultivated for its oily seeds.
Leaves narrow and entire. Flowers are large, blue or
bluish violet and entire. Flowers are large, blue or
bluish violet and pentamerous in terminal panicles.
Stamens - 5 and alternating with staminodes. Fruits
capsular, with five cells, each containing 2 seeds.
Seeds are yellowish or blackish brown, small, flattened,
oval, with smooth and shining seed coat and small albumen.
Traditional uses:
The traditional medicinal uses of this multi-purpose
seed are well-documented. The father of modern medicine,
Hippocrates, discovered the anti-mucous and expectorant
properties of linseed, and recommended it to soothe
coughs. A poultice of linseed oil is effective in treating
boils, pocks, burns and psoriasis due to its antiseptic
and anti-inflammatory properties. A couple of spoonfuls
of the seed act as a bulking agent useful to ease cases
of constipation while the oil can also act as a mild
laxative due to its lubricating effects, which also
contributes to its use in aiding the passage of gallstones.
Anecdotal evidence suggests its use in helping to leach
toxic heavy metals such as lead and aluminum from the
body and researchers have found that it also tends to
reduce fat and sugar levels and may help prevent cancer.
Phytochemistry:
Flax seed, next to fish oil, contains the highest concentration
of the essential nutrient, Alpha Linolenic Acid (LNA),
commonly called Omega 3.
Other constituents include:
- Mucilage (6%)
- Cyanogenic glycoside (linamarin) -- a respiratory
system sedative
- Bitter principle
- Linseed oil in the seeds contains cis-linoleic
(24%) and alpha-linolenic acids (36-50%), vitamins
A, B, D, E, minerals, amino acids (25%)
Pharmacology:
- Flaxseed contains soluble fiber, like that found
in oat bran, and is an effective laxative.
- Studies of flaxseed preparations to lower cholesterol
levels report mixed results.
- Some studies suggest that alpha-linolenic acid
(a substance found in flaxseed and flaxseed oil)
may benefit people with heart disease. But not enough
reliable data are available to determine whether
flaxseed is effective for heart conditions.
- Study results are mixed on whether flaxseed decreases
hot flashes.
- NCCAM is funding studies on flaxseed. Recent
studies have looked at the effects of flaxseed on
high cholesterol levels, as well as its possible
role in preventing conditions such as heart disease
and osteoporosis.
- The seeds contain both soluble and insoluble
fiber which promote intestinal health and lignans,
a form of phytoestrogens believed to help protect
against colon, prostate, and breast cancers.
Main Actions:
Analgesic; Cancer; Cardiotonic; Demulcent; Emollient;
Expectorant; Laxative; Nervine; Pectoral; Resolvent.
Main Uses:
Flax Seed is used internally in habitual constipation,
functional disorders of the colon resulting from the
misuse of laxatives and irritable colon, as a demulcent
preparation in gastritis and enteritis. These little
seeds improve digestion, help stabilize blood glucose
levels, fight tumor formation and enhance cardiovascular
health. The freshly ground seed can be added to cereal,
soups, or stews as a thickener. Regular use may help
balance estrogen activity, reducing the risk of some
cancers and heart disease and benefiting menopausal
women.
