This document provides information about flaxseeds (also known as linseeds). It discusses the flax plant structure, history of flaxseed use in India and other regions, how flaxseeds are grown and harvested, nutritional composition and health benefits of flaxseeds. Key points include that flaxseeds are high in fiber, omega-3 fatty acids and lignans, and may provide benefits for heart, digestive and brain health. The document also covers processing methods for flaxseeds, such as solvent extraction and expeller pressing to produce flaxseed oil, as well as commercial products containing flaxseeds.
Flaxseeds are the richest source of α-linolenic acid and lignans. It is also a considerable potential source of soluble fiber, antioxidants and high quality protein. The role of flaxseed lignans and ω-3 fatty acid in reducing the risks associated with cardiac and coronary disease, cancer (breast, colon, ovary and prostate) and other human health risk factors has been well known.

Linseed oil is obtained by expression of linseeds, belonging to family Linaceae. This drug becomes important since it is obtained from fruit source. Here the synonyms, biological sources (scientific names & Family), geographical sources (what are the countries where it can be collected), chemical constituents, identification tests and uses has been discussed in brief.
Flax (also known as common flax or linseed), with the binomial name: Linum usitatissimum, is a member of the genus Linum in the family Linaceae. It is a food and fibre crop that is grown in cooler regions of the world. The species is native to the region extending from the eastern Mediterranean, through Western Asia and the Middle East, to India.
Flax is grown for its use as an edible oil, as a nutritional supplement, and as an ingredient in many wood finishing products. Flax is also grown as an ornamental plant in gardens. Flax fibers are used to make linen.

Flaxseed- Miraculous Anti-ageing Divine Food
What is Flaxseed and how can it benefit me? I was faced with this question when I started hearing about Flaxseed not long ago. It became a ‘buzz word’ in society and seems to be making great role in increased health for many. I wanted to join that wagon of wellness and so I researched until I felt satisfied that it could help me, too. Here are my findings.
Flaxseeds are slightly larger than sesame seeds and have a hard shell that is smooth and shiny. Their color ranges from deep amber to reddish brown depending upon whether the flax is of the golden or brown variety. Botanical name of flaxseeds is Linum usitatissimum, the flax plant, which has been widely used for thousands of years as a source of food, clothing and decorating houses (paints, varnish, linoleum flooring etc.). Usitatissimum means useful seeds. The crushed seed makes a very useful poultice in the treatment of ulceration, abscesses, deep-seated inflammations and even skin cancers. Flaxseeds have become very popular recently, because they are a richest source of the Omega 3 essential fatty acid; known as Alpha Linolenic Acid (ALA), lignans and fiber. People in the new millennium may see flaxseed as an important new food super star.
Flaxseed also increase oxygen consumption at the cellular level resulting in increased energy and stamina, and feeling of well-being. In fact, there’s nobody who won’t benefit by adding flaxseed to his or her diet. Even Gandhi wrote in his book: “Wherever flaxseed becomes a regular food item among the people, there will be better health.” In the 8th century, French king Charle magne even passed a law requiring his people to use flax seed so that they would be healthier.

Nutritional fact, Intoxication and Therapeutic Aspects of Pennisetum sps (Bajara): A Review
In the modern era, various illnesses have been managed or treated in Africa and other parts of the world using plants as a source of medication.
An estimated 80% of the world's population uses herbal plants to cure and control serious illnesses, according to a WHO report .
Apart from traditional drugs, herbal foods are currently under focus for the treatment of obesity, Mets, T2DM, and NAFLD.
Grains such as oats, quinoa, and barley are reported to have anti-hyperglycemic, anti-hyperlipidemic, and anti-inflammatory effects on humans and rats
pearl millet (Pennisstum glaucum) is a multifunctional cereal crop which belongs to the Poaceae family.
It is generally referred to in various local Indian languages as bajra, bajri, sajje, kambu, kamban, sajjalu, etc.
It is widely used for food and forages . Pearl millet is the third largest major crop after rice and wheat.
Excess acidity in the stomach following food consumption is the most important explanation for stomach ulcers.
Generally, pearl millet is suggested for stomach ulcer treatment, because it is one of the very few grains that alkalizes the stomach and prevents stomach ulcers or decreases the effect of ulcers
Pearl millet helps to keep blood sugar levels stable for a long time in diabetic patients.
It is also helpful for diabetes patients because it has a comparatively small glycaemic index that helps steadily digest and contain glucose at a slower pace than other foods.
The amylase activity of pearl millet is very high, about 10 times than that of wheat.
Generally pearl millet is classified as a low-glycaemic index (GI) food because of its high fibre and protein content.
Lignin and phytonutrients are good antioxidants in pearl millets that prevent cardiovascular diseases.
Pearl millet is also considered healthy for heart protection. There have been high levels of magnesium present in pearl millet, which regulates blood pressure and alleviates heart stress.
It has rich magnesium that decreases the incidence of respiratory symptoms in asthma patients and is also helpful in preventing migraine attacks.
Pearl millet has high phosphorus content which is very important for bone growth and development as well as for the production of ATP, the body’s energy currency.
As millets are known to reduce the risk of cancer, it is expected that pearl millet will have the same effect potentially due to its high content in magnesium and phylate compound.
The greatest obstacle facing people who wish to lose weight is to regulate their con- sumption of calories. Pearl millet will support the weight loss process because the fibre content is high.
Celiac disease is a disorder in which a person could not endure even a little gluten in the diet. Since millet is gluten-free, it is great for people with celiac disease
Pearl millet is widely recommended for people with elevated cholesterol levels. It comprises a phytoc

2. INTRODUCTION : knowing Flaxseed …
• We, in India have an amazing capacity to ignore our plant Kingdom riches and consign
them to the archives, till someone from the developed countries publishes exciting news
about the medical and other uses of such things.
Take FLAX.
• There was so much one read about flax seeds, all the time. How useful they were, how
best to take them, how NOT to take them, the quantities, the various recipes, and so on
and so forth...
• At the very first; I found out what flax was in Marathi (my mother tongue) and then had an
enlightening discussion with my grandmother . She told me that right from her childhood
in the plains of Maharashtra, it was always routine for houses to have earthen pots in
which this flax seeds chutney was stored, for eating along with jowar bhakri .
Turns out that flax seed has been used for a very long time here in India.
Flaxseed chutney
3. • It may be tiny, but it’s mighty:The flax seed carries one of the biggest nutrient payloads on
the planet.
• Other common name(s): flaxseed , linseed, lint bells, linum
Scientific/medical name(s): Linum usitatissimum
• Flax is an annual plant cultivated for its fibre, which is used in making linen.
Flaxseed, flaxseed oil and linen are all products of flax, one of the first crops to be
domesticated.
FLAX : PLANT
• The scientific name for flax—Linum usitatissimum— reveals a lot about our human
relationship to this plant.
• The "linum" part of this name sounds a lot like "linen," which is a fabric that has been
made from flax for over 3,000 years.The "usitatissimum" part of its name means "of
greatest use" in Latin, and that quality also rings true in our relationship to flax.
Linen
4. FLAXSEED PLANT STRUCTURE :
• Flax, Linum usitatissimum, is an upright annual plant growing to 1.2 m (3 ft. 11 in) tall, with
slender stems.
• The flowers are pure pale blue, 15–25 mm diameter, with five petals; they can also be bright
red.
• The fruit is a round, dry capsule 5–9 mm diameter, containing several glossy
brown seeds shaped like an apple pip, 4–7 mm long.
• referring to the plant itself, the word "flax" may refer to the unspun fibres of the flax plant.
5. CLASSIFICATION :
• Brown flax and golden flax (sometimes called yellow flax) are the two basic varieties of flax
• they are similar in their nutritional composition, with one important exception.
One specific strain of yellow flax called "solin" was been developed by agricultural scientists
to be processed and sold as a cooking oil that could substitute for oils like sunflower seed
oil.
• Solin has been approved by the Food and Drug Administration (FDA) as a GRAS list
food, and it is sometimes being produced under the trademarked name "Linola" (TM).
• Linola which has a completely different oil profile and is very low in omega-3 FAs.
New Zealand flax also has a rich history of use for its fibre content, however, as well as
traditional medicinal uses as developed by the Maori peoples of New Zealand.
• New Zealand flax, even though it bears the same name, is not related to the flax
plant Linum usitatissimum
SOLIN OIL New Zealand flax
6. HISTORY :
• Flax is amongst the oldest fiber crops in the world.
• flax cultivation may have started even thousands of years earlier, during the Neolithic Era
of approximately 10,000 BC.
• Sometime between 4000 and 2000 BC, flax cultivation became a common practice in
countries bordering the Mediterranean Sea and in regions of the Middle East
• Flax was extensively cultivated in ancient China and ancient Egypt.[4] The use of flax for the
production of linen goes back at least to ancient Egyptian times. Pictures on tombs and
temple walls atThebes depict flowering flax plants.
Thebes – Egypt
7. GROW AND HARVEST :
• Flax tolerates a range of soils and climates.
• Choose a site in full sun, with deep, fertile, well-drained soil, and prepare it as you would for
growing vegetables or flowers.
• Flax grows best in cool weather. This can be as early as January or as late as May,
depending on where you live.
• Seedling flax plants quickly develop a good root system and need watering only if the
weather is unusually warm, dry or windy.
• The only common, serious crisis in growing flax is that the tender stalks sometimes get
knocked flat by hail or heavy rainstorms.

10. NUTRITIONAL PROFILE OF FLAXSEED : What's in flaxseed ?
• while it’s not technically a grain, it has a similar vitamin and mineral profile to grains, while
the amount of fiber, antioxidants, and Omega-3 fatty acids in flax leaves- grains in the
dust.
• Additionally, flax seed is very low in carbohydrates, making it ideal for people who limit
their intake of starches and sugars.
• its combination of healthy fat and high fiber content make it a great food for weight loss
and maintenance
• flax seed is high in most of the B vitamins, magnesium, and manganese, but this little
seed is just getting started.
There are three additional nutrient groups which flax seed has in abundance, and each has
many benefits.
I. Flax Seed is Rich in Omega-3 Fatty Acids:
• Among all 127 World's Healthiest Foods, flaxseeds comes out number one as a source of
omega-3s!
• Omega-3 fatty acids are a key force against inflammation in our bodies.
• Most of the oil in flax seeds is alpha linolenic acid (ALA)
11. II. Flax Seed is High in Fiber:
• You’d be hard-pressed to find a food higher in fiber -- both soluble and insoluble -- than flax.
• This fiber is mainly responsible for the cholesterol-lowering effects of flax.
• water-soluble, gel-forming fiber that can provide special support to the intestinal tract.
III. Flax Seed is High in Phytochemicals:
• Flax seed is high in phytochemicals, including many antioxidants.
• Lignans are fiber-like compounds, but in addition to their fiber-like benefits, they also
provide antioxidant protection due to their structure as polyphenols.
• It is perhaps our best source of lignans,When flaxseed is eaten, the lignans are activated by
bacteria in the intestine.
• promote fertility, reduce premenopausal symptoms, and possibly help prevent breast
cancer.
KEEP IN MIND :
a) flax seeds need to be ground to make the nutrients available (otherwise they just “pass
through”)
b) flax seed oil alone contains neither the fiber nor the phytochemicals of whole flax seed
meal.
12. HEALTH BENEFITS :
• The seeds of most plants are rich in nutrients and can provide us with health benefits.
• This combination of features—omega-3 fatty acids, high-lignan content, and mucilage gums
(high fibre content)—is a key factor in the unique health benefits of flaxseeds.
Cardiovascular Benefits Antioxidant and Anti-Inflammatory Benefits
Cancer Prevention
(lignan)
Digestive Health
Hailed with burning body fat, being high in omega-3s and charged
with fibre, these little seeds can really fire up our metabolism
13. • Protecting against radiation - a diet of flaxseed may protect skin tissue from being
damaged by radiation. its strong antioxidant and anti-inflammatory properties, works as
both a mitigator and protector against radiation pneumonopathy.
• Improving blood sugar - there is strong evidence to suggest that consuming flaxseed
everyday improves glycemic control in obese men and women with pre-diabetes
• Preventing hot flashes - dietary intake of flaxseed can decrease the risk of hot flashes
among postmenopausal women
• Omega-3 fatty acids have been shown to have numerous health benefits including a
reduction in inflammation, blood pressure and decreased blood triglyceride levels and
incidence of coronary heart disease.
• Flaxseed is also used for acne, attention deficit-hyperactivity disorder (ADHD), kidney
problems
• Other uses include treatment of sore throat, upper respiratory tract infections (URTI), and
cough.
14. HOW DOES ITWORK ?
• The fiber in flaxseed is found primarily in the seed coat.Taken before a meal, flaxseed fiber
seems to make people feel less hungry, so that they might eat less food.
• Researchers believe this fiber binds with cholesterol in the intestine and prevents it from
being absorbed.
• Flaxseed also seems to make platelets, the blood cells involved in clotting, less sticky.
Overall, flaxseed’s effects on cholesterol and blood clotting may lower the risk of
“hardening of the arteries” (atherosclerosis).
• Flaxseed is sometimes tried for cancer because it is broken down by the body into
chemicals called “lignans.” Lignans are similar to the female hormone estrogen - so
similar, in fact, that they compete with estrogen for a part in certain chemical reactions.
• natural estrogens seem to become less powerful in the body. Some researchers believe
that lignans may be able to slow down the progress of certain breast cancers and other
types of cancers that need estrogen to grow.
15. PRECAUTIONS :
• Flaxseed, like any supplemental fiber source, should be taken with plenty of water;
otherwise, it could worsen constipation or, in rare cases, even cause intestinal blockage.
Both flaxseed and flaxseed oil can cause diarrhoea
• The fiber in flaxseed may lower the body’s ability to absorb medications that are taken by
mouth
• Do not eat raw or unripe flaxseeds -- they may be poisonous. Raw Flax seeds, contain a
substance called cyanate, which can be harmful to the body in larger quantities.
• People with a bowel obstruction, inflamed bowel, or narrowed oesophagus should not
take flaxseed. It is high in fiber and could make the condition worse
• It might also cause gastrointestinal (GI) side effects such as bloating, gas, abdominal
pain, constipation, diarrhoea, stomach-ache, and nausea.
• Bleeding disorders: Flaxseed might slow clotting.
16. • Avoid eating flax seeds whole.They have the nasty habit of leaving your body in the same
condition they came in ...
• Relying on flaxseed treatment alone and avoiding or delaying conventional medical care
for cancer may have serious health consequences
• The omega-3 fatty acids in flaxseeds aren't taken up as well by the human body as the
omega-3 in fish oil
• Side effects associated with the consumption of flaxseed, include:
Stomach pains
Nausea
Constipation
Diarrhoea
17. INTERACTIONSWITH MEDICATIONS :
• Flaxseed may block the normal absorption of medicines.
• Always take medicines at least one hour before or two hours after using flaxseed.
• If you are currently being treated with any of the following medications, you should not
use flaxseed without first talking to your health care provider:
Blood-thinning medications --
• Omega-3 fatty acids may increase the risk of bleeding, especially if you also take blood
thinners such as warfarin or aspirine
Medications for diabetes --
• Flaxseed may lower blood sugar levels. If you are taking medicines for diabetes, including
insulin, you should use flaxseed (ALA) only under your doctor’s supervision.
Birth control pills or hormonal replacement therapy (HRT) --
• Flaxseed may change hormonal levels and change the effects of oral contraceptives or
HRT.
Antibiotic drugs
Bacteria in the intestine convert some of the chemicals in flaxseed into lignans, which are
thought to be responsible for many of the possible benefits of flaxseed. However, because
antibiotics kill these bacteria, lignans are not formed as usual.This might alter the effects of
flaxseed.
18. PROCESSINGOF FLAXSEED :
• The majority of flaxseed is processed to extract oil for use in industrial products such as
paints or floor coverings.
• Meal produced during extraction is concentrated in protein and used in livestock feeds; this
product is often referred to as linseed meal.
2 most commonly used processes for flaxseed oil extraction are :
i. prepress solvent extraction
ii. expeller press extraction
• In Prepress solvent extraction :
It extracts virtually all of the oil using a combination of mechanical extraction and solvent
extraction.
• expeller processing relies solely on mechanical pressure to extract oil
19. Prepress Solvent Extraction of Flaxseed :
• Prepress solvent extraction uses a combination of mechanical pressure and chemical
extraction and is the preferred oilseed extraction method for most large scale plants as it is
the most effective method of extracting oil.
CLEANING
• Seeds are cleaned to remove stones, chaff or dirt to prevent damage or wear on the processing equipment
followed by preheating.
FLAKING
• The seed is fed between the rolls and crushed into a very thin flake
• to rupture the cell walls and to increase the surface area for oil extraction
COOKING
• to reduce the viscosity of the oil and to allow it to migrate out of storage bodies in the seed.
PREPRESS
• compression effect forces the oil out of the small openings in the wall and is collected
• extracts almost half of the oil and prepares a cake that is suitable for solvent extraction.
SOLVENT
EXTRACTION
• Hexane is flushed through the cake, it solubilizes and absorbs the oil from the flax meal.
• After completion, the solvent is allowed to drain out of the meal.
• During evaporation , hexane is boiled off leaving the oil.
20. Mechanical Extraction of Flaxseed :
• Expeller plants can be economically constructed for small scale production.
• With the recent interest in incorporating flax oil into human diets, people are attracted to
mechanically extracted oil -- on the basis that a solvent was not used in the process of
extraction.
• The meal product resulting from mechanical extraction has a residual oil content of over
5% and offers a meal with elevated energy content as compared to solvent-extracted meal.
• it is common practice to install two sets of expeller presses.The first press extracts
approximately 50% of the oil; the cake is then fed into a second press and additional
pressure is applied to drive out as much of the remaining oil as possible.
21. FAQSABOUT FLAXSEEDS :
Which is better for me, whole or ground flax seed?
Ground flax seed provides more nutritional benefits than does whole seed.
Grinding flax seeds breaks them up, making them easier to digest when eaten.Then the
body can profit from all that flax goodness
If whole flax seeds remain unbroken, they may pass undigested through the body, reducing
the nutritional advantage of eating flax seed in the first place
How should I store flax seed and for how long will it keep?
ForWHOLE Flaxseed :
Whole flax seed comes with Nature’s own finest packaging – its natural hard hull keeps it
fresh.You can store clean, dry, good quality whole flax seed at room temperature for up to a
year.
For Ground Flaxseed :
Once you grind flax seed, there is greater risk of it developing an off-flavour and taste.
you should refrigerate it in an airtight, opaque container. Ground flax seed handled this way
will keep for up to 90 days.
