New Roots Herbal Quercetin Bioflavonoid Complex 250mg

This complex contains quercetin, bromelain, and rutin, that scavenge oxygen radicals, inhibit xanthine oxidase, and inhibit lipid peroxidation.*

Quercetin is widely distributed in the plant kingdom and is the most abundant of the flavonoid molecules. It is found in many often-consumed foods including apples, onions, tea, berries, and brassica-type vegetables, as well as many seeds, nuts, flowers, barks, and leaves. It is also found in medicinal botanicals, including Ginkgo biloba, Hypericum perforatum (St. John’s wort), Sambucus canadensis (elder), and many others. It is often a major component of the medicinal activity of the plant, and has been shown in experimental studies to have numerous effects on the body. All flavonoids have the same basic chemical structure, a three-ringed molecule with hydroxyl (OH) groups attached. A multitude of other substitutions can occur, giving rise to the many types of flavonoids. Flavonoids often occur in foods as a glycoside, meaning they have a sugar molecule (rhamnose, glucose, galactose, etc.) attached to the center ring. Quercetin is the aglycone (meaning minus the sugar molecule) of a number of other flavonoids, including rutin, quercetin, isoquercetin, and hyperoside. Quercetin appears to have many beneficial effects on human health, including cardiovascular protection, possibly decreasing cancer activity risks, antiulcer effects, antiallergy activity, cataract prevention, antiviral activity, and anti-inflammatory effects. Flavonoids, as a rule, are antioxidants, and a number of quercetin’s effects appear to be due to its antioxidant activity.* Quercetin scavenges oxygen radicals, inhibits xanthine oxidase, and inhibits lipid peroxidation in vitro. As another indicator of its antioxidant effects, quercetin inhibits oxidation of LDL-cholesterol in vitro, probably by inhibiting LDL oxidation itself, by protecting vitamin E in LDL from being oxidized or by regenerating oxidized vitamin E. By itself, and paired with ascorbic acid, quercetin reduced the incidence of oxidative damage to neurovasculature structures in skin, and inhibited damage to neurons caused by experimental glutathione depletion. Flavonoids, particularly quercetin, are inhibitors of allergic (IgE-mediated) mediator release from mast cells and basophils. In reported laboratory studies, quercetin inhibited not only IgE-mediated allergic mediator release from mast cells but also IgG-mediated histamine and SRS‑A (peptidoleukotriene). Interestingly, quercetin was much more potent as an inhibitor of the release of SRS‑A than histamine, suggesting that it might also inhibit the biosynthesis of SRS‑A. Subsequently, it was demonstrated that quercetin was an effective inhibitor of 5‑lipoxygenase; this property of the compound most likely accounts for its effect on peptidoleukotriene biosynthesis.*

Quercetin is indicated in any inflammatory condition, as it inhibits the formation of the inflammatory mediators prostaglandins and leukotrienes, as well as histamine release. This may be especially helpful in asthma, as leukotriene B4 is a potent bronchial constrictor. Quercetin’s inhibition of xanthine oxidase decreases the formation of uric acid, and thus it may be of value in the treatment of gout. Animal studies have shown quercetin to be protective of gastric ulceration caused by ethanol, by inhibiting lipid peroxidation of gastric cells and/or by inhibition of gastric acid secretion. An interesting aspect of quercetin’s antiulcer effect is that it has been shown to inhibit the growth of Helicobacter pylori in a dose-dependent manner in vitro.

Bromelain is found mostly in the stems of pineapples and is available through extraction as a dietary supplement.

What is it? Bromelain is a group of proteolytic enzymes that are essential for digesting protein. Although most enzymes are considered to be poorly absorbed, the body can absorb significant amounts of bromelain. People who suffer from malabsorption usually use proteolytic type enzymes to help with their ailment. Bromelain can prevent excessive blood platelet stickiness because it is a natural blood thinner. Through the positive reports in clinical trials, bromelain was shown to decrease symptoms of angina and thrombophlebitis. In addition, bromelain reduces the thickness of mucus, which can benefit patients with asthma or chronic bronchitis.

How does it work? Bromelain is a natural anti-inflammatory enzyme that works by breaking down fibrin, a blood-clotting protein that can impede good circulation and prevent tissues from properly draining. Bromelain is used particularly with strains, muscle injuries, pain, swelling, and tenderness that accompany sports injuries. Bromelain also blocks the production of compounds that can cause swelling and pain. When inflammation is minimized, blood can flow easily to a damaged area, easing pain and speeding up the healing process. Because of its anti-inflammatory effects, bromelain has been found to significantly reduce postoperative swelling. Research has also found that bromelain has an effect in reducing swelling, bruising, and pain for women having minor surgery after they have given birth (episiotomy). Bromelain is often blended with trypsin, an enzyme that alleviates symptoms of urinary tract infection due to its anti-inflammatory action. Research comparing the two enzymes in combination with antibiotics to placebo plus antibiotics reported that reductions of symptoms were good to excellent with all of the patients given these enzymes and antibiotics. Bromelain can also increase the uptake of bioflavonoids.*

Rutin has strong antioxidant properties. Rutin can also chelate metal ions, such as iron, thereby reducing the Fenton reaction (production of damaging oxygen radicals). Rutin also seems to stabilize vitamin C. If rutin is taken together with vitamin C, the activity of ascorbic acid will be intensified. Rutin is important because it strengthens capillaries and can help people who bruise or bleed easily. Studies have demonstrated that rutin can help to stop venous edema, that is an early sign of chronic venous disease of the leg. Rutin has anti-inflammatory effects. Animal studies have shown that rutin has preventive and healing effects. There are indications that rutin can reduce the risks of some cancerous and precancerous conditions. Rutin may help to prevent atherogenesis and reduce the cytotoxicity of oxidized LDL-cholesterol.*

Good quality pillows overall
Size: King (Pack of 2), Color: White
Got a set of these for my wife and myself as we were struggling with our old pillows. These have some really good qualities and some things we'd like to see changed. First, the good: These are look and feel like they are high quality and made with good materials. The foam itself has a very nice feel to it. We love the fact they are adjustable to add or remove foam. They come with a pretty substantial amount already in the pillow. We appreciate the CertiPur certification. Now the improvements or changes we'd like to see: The foam, while feeling great, doesn't bounce back well if you scrunch your pillows, and so every day you have to fluff and reshape the pillow, moreso than some other memory foam pillows we've owned. One side of the pillow is cooled and you can feel that even through the pillow case, and that's a great thing. However, one side is not cooled and we'd have preferred if both sides were made of the cooling material. Overall, these are good pillows and we are not disappointed with the purchase. They are not, however, our perfect pillows (which do seem hard to find), and at some point in the future will probably make their way to the guest bedroom. We would rate them as some of the better pillows we've tried and feel most people would probably like them.

Perfect Pillow
Size: Queen (Pack of 1), Color: White
These are the best pillows ever. You can adjust the firmness or softness to whatever you want. For years i used a soft latex pillow , which you cant get anymore. I will never use another pillow. I have purchased 6 of these after the first one. You pick your own comfort level. Best ever. No more neck aches.

Hallelujah… finally, I found the right pillow!!!
Size: Queen (Pack of 1), Color: White
I have spent a lot of money searching for the right pillow. I recently tried to Tempur-pedic that cost twice with this pillow cost. Tempur-pedic flattened out. I’ve had this pill for a few weeks now and it works wonders. I am a paraplegic. You can have a lot of neck problems. I love the fact that this pillow is adjustable. I immediately saw it was too stuffy and took a bunch out. It works perfect so glad I didn’t spend money on a $200 purple pillow. I read a lot of reviews and there were a lot of complaints about the odor. Mine did smell funny when it came out of the box. I immediately threw it in the dryer with a few bounce fabric sheets came out smelling fine. Pillows are a very individual thing, but I think for 40 bucks this pillow is worth a try. I’m really enjoying mine about one of those silk pillowcases to go over it and it sleeps cool and comfortable. Best wishes in your search for the right pillow. Update: I’ve been using this pillow several months and it continues. Give me a good night rest pain-free.. well worth the money. UPDATE: I have been using this pillow for three months and it still works great. It does not flat out or get hot..

Soft comfortable very good pillow
Size: King (Pack of 1), Color: White
I really love my new pillow it's great and comfortable. Yes, it has a little smell, but if you wash the pillowcase and put the pillow on the window for a day you won't notice anything anymore.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend
