Quercetin

Definition:Quercetin belongs to a group of plant pigments called flavonoids that are largely responsible for the colors of many fruits, flowers, and vegetables. Flavonoids, such as quercetin, provide many health-promoting benefits. They act as antihistamines (which are useful in reducing allergy symptoms) and help reduce inflammation associated with various forms of arthritis. Quercetin also works as an antioxidant by scavenging damaging particles in the body known as free radicals. These particles occur naturally in the body but can damage cell membranes, interact with genetic material, and possibly contribute to the aging process as well as the development of a number of conditions including heart disease and cancer. Antioxidants such as quercetin can neutralize free radicals and may reduce or even help prevent some of the damage they cause.

Quercetin is a phytochemical that is part of the coloring found in the skins of apples and red onions. It has been isolated and is sold as a dietary supplement.

Quercetin is a flavonoid and, to be more specific, a flavonol. It is the aglycone form of a number of other flavonoid glycosides, such as rutin and quercitrin, found in citrus fruit, buckwheat and onions. Quercetin forms the glycosides quercitrin and rutin together with rhamnose and rutinose, respectively.

Occurrence:
Quercetin is a naturally-occurring polar auxin transport inhibitor.

Foods rich in quercetin include capers (1800mg/kg), lovage (1700mg/kg), apples (440mg/kg), tea (Camellia sinensis), onions, especially in red onions (higher concentrations of quercetin occur in the outermost rings), red grapes, citrus fruits, broccoli and other leafy green vegetables, cherries, and a number of berries including raspberry, bog whortleberry (158 mg/kg, fresh weight), lingonberry (cultivated 74mg/kg, wild 146 mg/kg), cranberry (cultivated 83 mg/kg, wild 121 mg/kg), chokeberry (89 mg/kg), sweet rowan (85 mg/kg), rowanberry (63 mg/kg), sea buckthorn berry (62 mg/kg), crowberry (cultivated 53mg/kg, wild 56 mg/kg), and the fruit of the prickly pear cactus. A recent study found that organically grown tomatoes had 79% more quercetin than “conventionally grown”.

A study by the University of Queensland, Australia, has also indicated the presence of quercetin in varieties of honey, including honey derived from eucalyptus and tea tree flower

Where To Find Quercetin:
To get more quercetin, you can increase your intake of apples and red onions, which will improve your diet. If you need more therapeutic impact, quercetin is available in health food stores and online.

Medicinal properties:
Quercetin is found to be the most active of the flavonoids in studies, and many medicinal plants owe much of their activity to their high quercetin content. Quercetin has demonstrated significant anti-inflammatory activity because of direct inhibition of several initial processes of inflammation. For example, it inhibits both the manufacture and release of histamine and other allergic/inflammatory mediators. In addition, it exerts potent antioxidant activity and vitamin C-sparing action.

Quercetin’s anti-histamine action may help to relieve allergic symptoms and asthma symptoms. The anti-inflammatory properties may help to reduce pain from disorders such as arthritis. Men who are concerned about prostate problems would also benefit from quercetin. Quercetin may also help reduce symptoms like fatigue, depression and anxiety.

Quercetin also shows anti-tumour properties. A study in the British Journal of Cancer showed that, when treated with a combination of quercetin and ultrasound at 20 kHz for 1 minute duration, skin and prostate cancers show a 90% mortality within 48 hours with no visible mortality of normal cells. Note that ultrasound also promotes topical absorption by up to 1,000 times making the use of topical quercetin and ultrasound wands an interesting proposition.

Recent studies have supported that quercetin can help men with chronic prostatitis, and both men and women with interstitial cystitis, possibly because of its action as a mast cell inhibitor.

Quercetin is a powerful antioxidant. It is also a natural anti-histamine, and anti-inflammatory. Research shows that quercetin may help to prevent cancer, especially prostate cancer.

Quercetin may have positive effects in combating or helping to prevent cancer, prostatitis, heart disease, cataracts, allergies/inflammations, and respiratory diseases such as bronchitis and asthma[citation needed]. It also has been claimed to have antidepressant properties, however any claim of quercetin action against neurological diseases should be treated with skepticism due to the fact that quercitin is a neurotoxin in vitIt also may be found in dietary supplements.

An 8-year study found that three flavonols — kaempferol, quercetin, and myricetin — were associated with a reduced risk of pancreatic cancer of 23 percent.

Drug interactions:
Quercetin is contraindicated with antibiotics; it may interact with fluoroquinolones (a type of medicinal antibiotic), as quercetin competitively binds to bacterial DNA gyrase. Whether this inhibits or enhances the effect of fluoroquinolones is not entirely clear.

Quercetin is also a potent inhibitor of CYP3A4, an enzyme that breaks down most drugs in the body. As such, quercetin would be expected to increase serum levels, and therefore effects, of drugs metabolized by this enzyme

[amazon_link asins=’B00LNOV8JO,B00QR7FTLU,B01N3340K7,B006MMOVOQ,B000UYFKZQ,B0001VVEIK,B003AYEHL6,B00UGHEHBU,B000SAPXWC’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’98082746-eac4-11e7-bc4b-c168c2de25c6′]

Description:
The rose hip and rose haw, is the pomaceous fruit of the rose plant, that typically is red-to-orange, but might be dark purple-to-black in some species.

CLICK & SEE THE PICTURES

Rose hips of some species, especially Rosa canina (Dog Rose) and R. majalis, have been used as a source of Vitamin C. Rose hips are commonly used as an herbal tea, often blended with hibiscus and as an oil. They can also be used to make jam, jelly, marmalade and wine. Rose hip soup, “Nyponsoppa”, is especially popular in Sweden. Rhodomel, a type of mead, is made with rose hips.

Health Benefits:
*Particularly high in Vitamin C, with about 1700–2000 mg per 100 g in the dried product, one of the richest plant sources.

*Rose hips contain vitamins A, D and E, essential fatty acids and antioxidant flavonoids.

*Rose hip powder is a remedy for rheumatoid arthritis.

*As an herbal remedy, rose hips are attributed with the ability to prevent urinary bladder infections, and assist in treating dizziness and headaches. Rose hips are also commonly used externally in oil form to restore firmness to skin by nourishing and astringing tissue.

*Brewed into a decoction, can also be used to treat constipation.

*.Rose hips contain a lot of iron, so some women brew rose hip tea during menstruation to make up for the iron that they lose with menses.

Rose hips are the seed pod left after the rose petals fall off. Rose hip tea, recommended because it is so rich in Vitamin C. The oil from rose hips, often called rosa mosqueta, is very nutritious and consists of 80 percent essential fatty acids. It was a mainstay of the Incas, for example, for its nutritional qualities.

Rose hip oil is also renowned for its benefits for the skin. In fact, it has multiple benefits.
It is particularly famous for any scars, including acne scars.

Here are some of the healing aspects rose hip oil is credited with for helping the skin:

*Scars, including acne scars and old scars

*Dry eczema

*Skin burns, including sunburn

*Rehydrates dry skin

*Repair damaged skin cells of all sorts

*Reduce wrinkles

*Benefit for dry, mature, aging skin

There are some pure moisturizing creams on the market (Aubrey for one). If you have a specific problem, it would be beneficial to obtain pure rose hip oil and massage two to three drops of the oil into the affected area every day.

Usage:
Rose hips are used for the creation of herbal tea, jam, jelly, syrup, beverages, pies, bread and marmalade, amongst others.

A few rose species are sometimes grown for the ornamental value of their hips; such as Rosa moyesii, which has prominent large red bottle-shaped fruits.

Rose hips have recently become popular as a healthy treat for pet chinchillas. Chinchillas are unable to manufacture their own Vitamin C, but lack the proper internal organs to process a variety of foods. Rose Hips provide a sugar free, safe way to increase the Vitamin C intake of chinchillas.

Rose hips may also be fed to horses. The dried and powdered form can be fed at a maximum of 1 tablespoon per day to help increase coat condition and help with new hoof growth.

The fine hairs found inside rose hips can be used as itching powder.

Roses may be propagated from hips by removing the seeds from the aril (the outer coating) and sowing just beneath the surface of the soil. Placed in a cold frame or a greenhouse, the seeds take at least three months to germinate.

By indigenous people:
Rose hips were used in many food preparations by the indigenous peoples of the Americas.

Rose hips are used for colds and influenza. The Latin binomial for this herb is Rosa laevigata.

Arthritis Can Be Managed With Diet and Exercise

exercise, yogaMany people with arthritis automatically reach for pain medication, but it is not always necessary to do so. There are other solutions that work just as well, or even better, for both osteoarthritis and rheumatoid arthritis.For instance, a variety of supplements — including bromelain, essential fatty acids, and glucosamine — can be beneficial for arthritis. But the best supplement of all is proper food. Proper, nutritious food has yielded health effects that surpass any supplement.

Exercises, including activities that engage the full body, are also recommended for individuals with arthritis. This:

  • Helps joint mobility
  • Prevents loss of lean muscle tissue
  • Maintains strength
  • Reduces pain and stiffness
  • Mobilizes stiff or contracted joints

But perhaps most importantly, it helps people with arthritis stay independent.

Weight-loss Remedies Puzzles US

WASHINGTON: When it comes to losing weight, US adults are bombarded with weight-loss claims and promises. This chaos, according to a new survey, makes individuals increasingly confused about what to believe in a bid to shed the flab.

As per a survey of 2,058 adults, conducted in late November by Harris Interactive on behalf of GlaxoSmithKline Consumer Healthcare, it was found that people were confused about what to believe in context of the claims made in regard to appetite suppressants, herbal products and dietary supplements.

Such dietary products are not required by the Food and Drug Administration (FDA) to submit safety or efficacy studies, or to include warnings about potential side effects on their labels.

However, the survey revealed that 3 in 5 Americans think that these products are at least somewhat effective.

CLICK & SEE

One-third wrongly believes that the products are approved for safety and effectiveness by the FDA before being sold to the public.

The interactive survey showed that two in five assumed that the government requires warnings about potential side effects on the labels of these products.

In fact, the analysis showed that about 18 million adults who want to lose weight in the coming time would rely on products that have not been reviewed and approved by the FDA before being sold to the public.

Rebecca Reeves, DrPH, RD, a GSK consultant who is past president of the American Dietetic Association and managing director of the Behavioural Medicine Research Centre at Baylor College of Medicine, said: “Weight-loss supplements claim to deliver extraordinary results with less effort than more traditional behavioural changes, such as diet and exercise.”

“However, there is scarce scientific data available to validate these product claims, which is unfortunate for the 66 percent or so of American adults who are overweight and obese,” she added.

Steven Burton, vice president, weight control, for GlaxoSmithKline Consumer Healthcare said: “Millions of overweight and obese Americans are incredibly frustrated with their efforts to lose weight, and unrealistic expectations and false hope feed that frustration.

Milk Thistle

[amazon_link asins=’B0013OULVA,B00EI46XSM,B003QB0QIQ,B000R2X33M,B01K20TYKY,B00TQ6TC80,B014ODUG6G,B01GQU9EZE,B002Y27K6O’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’b9dd80e9-849e-11e7-9421-4712645abeef’]

Botanical Name: Silybum marianum
Family: N.O. Compositae,Asteraceae
Subfamily: Lactucoideae
Tribe: Cynareae
Genus: Silybum
Species: S. marianum
Kingdom: Plantae
Order: Asterales

Synonym-:Marian Thistle.  Carduus lactifolius. Carduus marianus. Centaurea dalmatica. Mariana lactea.
Common Names-:- Cardus marianus,  Milk thistle,  Blessed milkthistle,   Marian thistle, Mary thistle, Saint Mary‘s thistle, Mediterranean milk thistle, Variegated thistle and Scotch thistle,  Mary thistle, holy thistle. Milk thistle is sometimes called silymarin, which is actually a mixture of the herb’s active components, including silybinin (also called silibinin or silybin).

Latin Name-:-Silybum marianum

Habitat : Milk Thistle is native to  S. Europe, N. Africa and W. Asia. Naturalized in Britain.  It grows on  waste places, usually close to the sea, especially if the ground is dry and rocky.  .

Parts Used-: Whole herb, root, leaves, seeds and hull.

Description: Members of this genus grow as annual or biennial plants. The erect stem is tall, branched and furrowed but not spiny. The large, alternate leaves are waxy-lobed, toothed and thorny, as in other genera of thistle. The lower leaves are cauline (attached to the stem without petiole). The upper leaves have a clasping base. They have large, disc-shaped pink-to-purple, rarely white, solitary flower heads at the end of the stem. The flowers consist of tubular florets. The phyllaries under the flowers occur in many rows, with the outer row with spine-tipped lobes and apical spines. The fruit is a black achene with a white pappus

Only two species are currently classified in this genus:

Silybum eburneum Coss. & Dur., known as the Silver Milk Thistle, Elephant Thistle, or Ivory Thistle
Silybum eburneum Coss. & Dur. var. hispanicum
Silybum marianum (L.) Gaertner, the Blessed Milk Thistle, which has a large number of other common names, such as Variegated Thistle.
The two species hybridise naturally, the hybrid being known as Silybum × gonzaloi Cantó , Sánchez Mata & Rivas Mart. (S. eburneum var. hispanicum x S. marianum)

A number of other plants have been classified in this genus in the past but have since been relocated elsewhere in the light of additional research.

S. marianum is by far the more widely known species. It is believed to give some remedy for liver diseases (e.g. viral hepatitis) and an extract, silymarin, is used in medicine. The adverse effect of the medicinal use of milk thistle is loose stools.

This handsome plant is not unworthy of a place in our gardens and shrubberies and was formerly frequently cultivated. The stalks, like those of most of our larger Thistles, may be eaten, and are palatable and nutritious. The leaves also may be eaten as a salad when young. Bryant, in his Flora Dietetica, writes of it: ‘The young shoots in the spring, cut close to the root with part of the stalk on, is one of the best boiling salads that is eaten, and surpasses the finest cabbage. They were sometimes baked in pies. The roots may be eaten like those of Salsify.’ In some districts the leaves are called ‘Pig Leaves,’ probably because pigs like them, and the seeds are a favourite food of goldfinches.

The common statement that this bird lines its nest with thistledown is scarcely accurate, the substance being in most cases the down of Colt’s-foot (Tussilago), or the cotton down from the willow, both of which are procurable at the building season, whereas thistledown is at that time immature.

Westmacott, writing in 1694, says of this Thistle: ‘It is a Friend to the Liver and Blood: the prickles cut off, they were formerly used to be boiled in the Spring and eaten with other herbs; but as the World decays, so doth the Use of good old things and others more delicate and less virtuous brought in.’

The heads of this Thistle formerly were eaten, boiled, treated like those of the Artichoke.

There is a tradition that the milk-white veins of the leaves originated in the milk of the Virgin which once fell upon a plant of Thistle, hence it was called Our Lady’s Thistle, and the Latin name of the species has the same derivation.
Cultivation:
Succeeds in any well-drained fertile garden soil. Prefers a calcareous soil and a sunny position. Hardy to about -15°c. The blessed thistle is a very ornamental plant that was formerly cultivated as a vegetable crop. Young plants are prone to damage from snails and slugs. Plants will often self sow freely.

Propagation:
Seed – if sown in situ during March or April, the plant will usually flower in the summer and complete its life cycle in one growing season. The seed can also be sown from May to August when the plant will normally wait until the following year to flower and thus behave as a biennial. The best edible roots should be produced from a May/June sowing, whilst sowing the seed in the spring as well as the summer should ensure a supply of edible leaves all year round.

Edible Uses :
Edible Parts: Flowers; Leaves; Oil; Oil; Root; Stem.
Edible Uses: Coffee; Oil; Oil.

Root – raw or cooked. A mild flavour and somewhat mucilaginous texture. When boiled, the roots resemble salsify (Tragopogon hispanicus). Leaves – raw or cooked. The very sharp leaf-spines must be removed first, which is quite a fiddly operation. The leaves are quite thick and have a mild flavour when young, at this time they are quite an acceptable ingredient of mixed salads, though they can become bitter in hot dry weather. When cooked they make an acceptable spinach substitute. It is possible to have leaves available all year round from successional sowings. Flower buds – cooked. A globe artichoke substitute, they are used before the flowers open. The flavour is mild and acceptable, but the buds are quite small and even more fiddly to use than globe artichokes. Stems – raw or cooked. They are best peeled and can be soaked to reduce the bitterness. Palatable and nutritious, they can be used like asparagus or rhubarb or added to salads. They are best used in spring when they are young. A good quality oil is obtained from the seeds. The roasted seed is a coffee substitute

HEALTH BENEFITS:

The seeds of this plant are used nowadays for the same purpose as Blessed Thistle, and on this point John Evelyn wrote: ‘Disarmed of its prickles and boiled, it is worthy of esteem, and thought to be a great breeder of milk and proper diet for women who are nurses.’

It is in popular use in Germany for curing jaundice and kindred biliary derangements. It also acts as a demulcent in catarrh and pleurisy. The decoction when applied externally is said to have proved beneficial in cases of cancer.

Gerard wrote of the Milk Thistle that:
‘the root if borne about one doth expel melancholy and remove all diseases connected therewith. . . . My opinion is that this is the best remedy that grows against all melancholy diseases,’
which was another way of saying that it had good action on the liver. He also tells us:
‘Dioscorides affirmed that the seeds being drunke are a remedy for infants that have their sinews drawn together, and for those that be bitten of serpents:’and we find in a record of old Saxon remedies that ‘this wort if hung upon a man’s neck it setteth snakes to flight.’ The seeds were also formerly thought to cure hydrophobia.
Culpepper considered the Milk Thistle to be as efficient as Carduus benedictus for agues, and preventing and curing the infection of the plague, and also for removal of obstructions of the liver and spleen. He recommends the infusion of the fresh root and seeds, not only as good against jaundice, also for breaking and expelling stone and being good for dropsy when taken internally, but in addition, to be applied externally, with cloths, to the liver. With other writers, he recommends the young, tender plant (after removing the prickles) to be boiled and eaten in the spring as a blood cleanser.
A tincture is prepared by homoeopathists for medicinal use from equal parts of the root and the seeds with the hull attached.

It is said that the empirical nostrum, antiglaireux, of Count Mattaei, is prepared from this species of Thistle.

Thistles in general, according to Culpepper, are under the dominion of Jupiter.
Milk thistles have been reported to have protective effects on the liver and to improve its function. They are typically used to treat liver cirrhosis, chronic hepatitis (liver inflammation), and gallbladder disorders. The active compound in Milk thistle credited with this effect is “silymarin”, and is typically administered in amount ranging from 200-500mg per day (common Milk Thistle supplements have an 80% standardized extract of silymarin). Increasing research is being carried out into its possible medical uses and the mechanisms of such effects. However, a previous literature review using only studies with both double-blind and placebo protocols concluded that milk thistle and its derivatives “does not seem to significantly influence the course of patients with alcoholic and/or hepatitis B or C liver diseases.”

Medicinal Uses:
Silymarin is poorly soluble in water, so aqueous preparations such as teas are ineffective, except for use as supportive treatment in gallbladder disorders because of cholagogic and spasmolytic effects. The drug is best administered parenterally because of poor absorption of silymarin from the gastrointestinal tract. The drug must be concentrated for oral use.   Silymarin’s hepatoprotective effects may be explained by its altering of the outer liver cell membrane structure, as to disallow entrance of toxins into the cell.  This alteration involves silymarin’s ability to block the toxin’s binding sites, thus hindering uptake by the cell.  Hepatoprotection by silymarin can also be attributed to its antioxidant properties by scavenging prooxidant free radicals and increasing intracellular concentration of glutathione, a substance required for detoxicating reactions in liver cells.

Silymarin’s mechanisms offer many types of therapeutic benefit in cirrhosis with the main benefit being hepatoprotection. Use of milk thistle, however, is inadvisable in decompensated cirrhosis.  In patients with acute viral hepatitis, silymarin shortened treatement time and showed improvement in serum levels of bilirubin, AST and ALT.

Treatment claims also include:

1.Lowering cholesterol levels
2.Reducing insulin resistance in people with type 2 diabetes who also have cirrhosis
3.Reducing the growth of cancer cells in breast, cervical, and prostate cancers.

4.Milk thistle is also used in many products claiming to reduce the effects of a hangover.

5.Milk thistle can also be found as an ingredient in some energy drinks like the AriZona Beverage Company Green Tea energy drink and Rockstar Energy Drink.


How It Is Used:

Milk thistle is a flowering herb. Silymarin, which can be extracted from the seeds (fruit), is believed to be the biologically active part of the herb. The seeds are used to prepare capsules containing powdered herb or seed; extracts; and infusions (strong teas).

What the Science Says:
There have been some studies of milk thistle on liver disease in humans, but these have been small. Some promising data have been reported, but study results at this time are mixed.
Although some studies conducted outside the United States support claims of oral milk thistle to improve liver function, there have been flaws in study design and reporting. To date, there is no conclusive evidence to prove its claimed uses.
NCCAM is supporting a phase II research study to better understand the use of milk thistle for chronic hepatitis C. With the National Institute of Diabetes and Digestive and Kidney Diseases, NCCAM is planning further studies of milk thistle for chronic hepatitis C and nonalcoholic steatohepatitis (liver disease that occurs in people who drink little or no alcohol).
The National Cancer Institute and the National Institute of Nursing Research are also studying milk thistle, for cancer prevention and to treat complications in HIV patients.

Other Uses:
Green manure; Oil; Oil..……A good green manure plant, producing a lot of bulk for incorporation into the soil.

Known Hazards  : When grown on nitrogen rich soils, especially those that have been fed with chemical fertilizers, this plant can concentrate nitrates in the leaves. Nitrates are implicated in stomach cancers. Diabetics should monitor blood glucose when using. Avoid if decompensated liver cirrhosis. Possible headaches, nausea, irritability and minor gastrointestinal upset
