Mayo Clinic (by Mayo Clinic Staff): “Overview—Polyunsaturated Fat”: Flaxseed (Linum usitatissimum) and flaxseed oil, which comes from flaxseed, are rich sources of the essential fatty acid alpha-linolenic acid—a heart-healthy omega-3 fatty acid. Flaxseed is high in soluble fiber and in lignans, which contain phytoestrogens. Similar to the hormone estrogen, phytoestrogens might have anti-cancer properties. Flaxseed oil doesn’t have these phytoestrogens. Flaxseed can be used whole or crushed, or in a powder form as meal or flour. Flaxseed oil is available in liquid and capsule forms.

The oil extracted from flaxseed is often called linseed oil and has been widely used for non-culinary purposes. Flaxseed oil has become a popular dietary supplement because of its reputed health-promoting properties. Flaxseed is a cultivar of Linum usitatissimum (family Linaceae). The fatty acid profile of flaxseed oil is largely comprised of polyunsaturates (66%), primarily the omega-3 fatty acid alpha-linolenic acid (ALA) (over 50%), and it is this that makes the oil oxidize rapidly (273). The oil also contains 440–588 mg/100 g of tocopherols. Flaxseed oil may reduce platelet aggregation for the prevention of blood clots and may improve autoimmune disorders. However, excessive intake of flaxseed supplement may cause hemorrhage. Due to its low oxidative stability, it has little use in food preparation.

Linseed, also known as lintseed or flax seed, is the dried ripe seed of Linum usitatissimum, a medicinal herb that was cultivated from earliest times. Linseed contains mucilage, and an oil which can be obtained by expressing the seed. Extract of linseed was found to be emollient and demulcent and was much used to treat superficial or deep seated inflammation in the form of a poultice to relieve irritation and pain and to promote suppuration (Grieve, 1931).

Flaxseed, also known as linseed, is the seed from the flax plant (Linum usitatissimum), which is a member of the Linaceae family. It is cultivated in many parts of the world for fiber and oil and was valued in Ancient and Early Modern times as both a food and medicine.5 Flaxseed is one of the richest sources of vitamins, minerals, proteins, and peptides, lipids, carbohydrates, lignans, and fibers.6 Lignans are low molecular weight polyphenols present in high concentrations in flaxseeds.7 Flaxseed lignans show significant protective effect in a variety of cardiovascular diseases, due to its anti-inflammatory,6,8 antioxidant,9,10 anti-fibrotic,11 antihypertensive,12 and anti-atherosclerotic13 activities. Accordingly, this study investigates the therapeutic effect of flaxseed lignans against cardiac hypertrophy.

Flaxseed (Linum usitatissimum L.) is one of the oldest crops that have been cultivated since the beginning of civilisation (Goyal et al.2014). It contains both soluble and insoluble fibres (Bernacchia et al.2014). The mucilage of flaxseed is located in the epidermal cell layer of the seed coat, and its extraction is achieved by aqueous method followed by a drying process (Emaga et al.2011). Seed mucilage is a soluble fibre that was hydrated and produced by mucilage secreting cells (Kreitschitz and Gorb 2018). The research claimed that seed mucilage showed good prebiotic potential as probiotics could utilise it for growth (Mueller et al.2017, Lai, et al.2020b). Its prebiotic properties are associated with the presence of arabinoxylan and were capable of stimulating the growth of L. acidophilus La-05 and has the potential to act as wall material for the encapsulation of probiotic (Bustamante et al.2015).

The flavonoids from Epimedium plants are antiosteoporotic components and activate certain receptors. The flavonoids are also used in prevention and treatment of postmenopausal osteoporosis. Research suggests that P. corylifolia has potent estrogenic effects, and its fruits are a useful remedy for bone fractures, osteomalacia, and osteoporosis (Jia et al., 2012). The extracts of both fruits and seeds and two isoflavones isolated from this plant stimulate bone formation. The roots of Pueraria lobata increase bone mineral density in rats and mice without estrogenic activity in the uterus (Jia et al., 2012). Trifolium pratense contains four flavonoids essential in decreasing bone loss. Salvia miltiorrhiza Bunge contains tanshinones and phenolics, some of which prevent ovariectomy-induced bone loss (Jia et al., 2012). Linum usitatissimum is a rich source of lignans, which have a positive effect on bones. It also has polyunsaturated fatty acids, which decrease the rate of bone resorption and decrease bone loss (Jia et al., 2012).
