Herbal remedies • Garlic and onion contain quercetin, which retards inflammatory reactions. • The leaf extract of the ginkgo tree contains substances that interfere with the platelet-activating factor, or PAF. This PAF has a starring role in triggering allergies, asthma, and inflammation. Caution: In large amounts, this herb can cause diarrhea, irritability, and restlessness. • Dr. Andrew Weil has said he knows of nothing so dramatic as the hay fever relief afforded by freeze-dried stinging nettle leaves. Dosages may vary, depending on the duration and severity of your symptoms.

Other nutrients that help during this stage include turmeric, bromelain, quercetin, rosemary, and green tea. 3. Progression. During this stage, precancerous masses become cancerous and begin to divide rapidly. Here's where omega-3 fatty acids, fish and flax oils, lignans as found in pure seeds and nuts, and tangeretin found in tangerines would be helpful. 4. Invasion and metastasis. At this point, tumor cells cross tissue compartment boundaries and intermix with cells on the other side of the boundary.

It is worth noting here that one of the many cancer-inhibiting effects of quercetin, a fiavone found in onions and broccoli, is to prevent a defect in this gene. An individual may inherit one defective copy of the tumor-suppressor protein gene p53 from a parent, giving that person a predisposition to develop cancer. Since p53 is a repair gene, when it malfunctions damaged DNA is able to escape, proliferate unchecked, and mutate into cancerous cells. As that person ages, she may then be more susceptible to external factors that can cause irregular cell proliferation.

Too high a level indicates poor binding functions and may require folic acid, bromelain, quercetin, and other supplements to correct the condition. EACH FORM OF CANCER IS UNIQUE Just as each person is unique and must be treated in that way, so too is an individual's cancer. Two people who have the same type of cancer are likely to receive the same type of conventional treatment (particularly if they are in the same hospital), but the results of their treatment may be quite different. Why does one person's cancer spread to the bone, another's to the liver, and another's not spread at all?

I advised Tom to stop taking his usual vitamin C supplement, because the form of quercetin he will take contains vitamin C in the form of magnesium ascor-bate as well as bromelain. Beta-Plex. Regular beta-carotene is not as effective as Beta-Plex, a full-spectrum carotene supplement taken from natural food sources. It contains high amounts of lycopene in synergy with other natural carotenoids. Tom's instructions were to mix 1 tablespoon freshly ground flaxseeds with 1 to 6 ounces organic yogurt and 5 drops of Beta-Plex.

Foods to emphasize include greens for their superb anti-inflammatory, blood-cleansing, and cooling effects; orange vegetables for carotenoids; root vegetables for liver support; chilies for immune boosting, circulation, blood cleansing, and thinning of mucosal secretions; ginger as an antiinflammatory and for thinning of mucosal sectetions; and onion for quercetin, immune building, and its affinity for lung tissue. Milk is best avoided by those with sinus problems. It suppresses the helpful thinning of mucosal secretions, and causes or aggravates symptoms in many allergic people.

Onions contain quercetin, the bioflavonoid compound mentioned earlier, but both of these lily bulbs also inhibit an enzyme, lipoxygenase, which generates an inflammatory chemical, note Drs. Murray and Piz-zorno in their Encyclopedia of Natural Medicine. They cite a study in which oral pretreatment of guinea pigs with an onion extract markedly reduced their asthmatic response to inhalant allergens. Onion has also been long noted in Ayurveda to have affinity for lung tissue. Chilies are excellent food for allergies, especially asthma, both to prevent and treat an attack.

Examples of this are the positive effects of combining folic acid and beta-glucan with 5-FU and also the use of quercetin with Adriamycin. 4. Supplements can inhibit cancer. All supplements synergistically assist the body's defense mechanisms as they inhibit metastatic cancer and prevent recurrences. I customize a nutritional supplement regime for each cancer patient I see, recommending particular supplements and directing the dosage and method of use. Some supplements are more effective when taken with meals, while others, such as enzymes, are best taken on an empty stomach.

In one study, the phytochemicals luteolin, baicalein, and quercetin were shown to inhibit the release of histamine, leukotrienes, and other immune chemicals from mast cells in a dose-dependent manner. Luteolin was the most potent. Dr. Duke's database reveals that luteolin is found in many anti-inflammatory plants, including celery seed (Apium graveolens), water plantain, wild indigo, arjuna bark, buddleia flowers, echinacea, ginkgo leaf, devil's claw root, flaxseed, honeysuckle flower, peppermint leaf, and grapes.

It contains the sesquiterpene lactones euperfolin, euperfolitin, and eufoliatin; polysaccharides, pyrrolizidine alkaloids, essential oils, many flavonoids including rutin and quercetin, and plant sterols. Research has shown it to stimulate white blood cells and increase phagocytosis four times better than echinacea. The flowering plant is collected in the late summer or fall, dried, cut, and then usually prepared into an alcohol tincture, though the dried herb can also be made into a tea.

One of the best combinations is quercetin, an antioxidant, and bromelain. DL-Phenylalanine (DLPA) This is a combination of L-phenylalanine, an essential amino acid, and D-phenylalanine, a nonnutrient amino acid that helps promote the production of endorphins, natural painkillers made in the brain. DLPA is very effective in the relief of chronic pain such as arthritis and back pain. While in most studies there have been no side effects at all from DLPA, it has raised blood pressure in a few people.

The bioflavonoids such as grapeseed extract and quercetin can help reduce inflammation reactions. Herbs for Pain White Willow Bark (Salix spp.): White willow bark was used as a pain reliever long before a chemist at the Bayer company in Germany synthesized acetylsalicylic acid, or aspirin, from one of its active ingredients in 1897. Aspirin is a synthetic drug (not found in nature), but various teas, decoctions, tinctures and poultices of trees of the salix species, most commonly known as willow and poplar, have been used to relieve pain for many centuries.

Quercetin is available in pill form. Optic Neuritis and Optic Atrophy "Optic neuritis" is an acute or chronic inflammation of the optic nerve. Often a nerve demyelination (destruction of the protective myelin sheath around the nerve fibers) takes place, similar to multiple sclerosis. Multiple sclerosis, diabetes, poor circulation, trauma, chemical poisoning, and other less common eye insults can cause it. There is often a sudden loss of visual acuity and pain with movement of the eye. The eye doctor can diagnose optic neuritis by examining the back of the eye.

Other appropriate Chinese herbs include moutan bark, scrophularia root (xuan shen or S. ningpoensis) and kochia fruit (di fu zi or AT. scoparia). It is interesting to note that both TCM doctors and Western herbalists use scrophularia root and burdock root to treat eczema.

Use organic blueberries if you can get them; also quercetin, 1500 mg daily. • A clinical study on 48 eyes was done to measure the ability of the Ayurvedic preparation called saptamrita Iauha in absorption of retinal hemorrhages. Rapid absorption of hemorrhage was observed in both diabetic and hypersensitive subjects. Mean duration for absorption was about 17 days, with complete clearance in 3 eyes, and partial clearance in the rest. Follow-up studies showed a 25% recurrence in treated eyes, compared to greater than 50% recurrence in control eyes (Sharma et al., 1992).

Other phytochemicals include the polyphenols like camosol in rosemary leaves or curcurmin in mustard and curry, the flavonoids like quercetin in berries and onions, or rutin in citrus fruits, and kaempferal in kale and other greens. These and 12,000 other phytochemicals work as teams with nutrients and fiber to strengthen the body's defenses against disease. Since our bodies evolved on diets that contained pounds, not ounces, of produce, it's likely our bodies function best on a high level of these phytochemicals.

Quercetin promotes insulin secretion and along with other flavonoids is a potent inhibitor of sorbitol accumulation in the tissues and blood. The flavonoids increase intracellular vitamin C levels, resulting in less leakage of blood into the tissues, preventing bruising, and maybe most important, enhancing the immune system. The diabetic should consider increasing the amounts of flavonoids in his diet per day and adding a flavonoid-rich extract, such as bilberry or grape seed. I personally take 200 milligrams of grape seed extract per day.

L-glutamine and quercetin supplements can be helpful. Cromolyn sodium is an effective medication. A Fungus Among Us Civilization would be much the poorer without yeast, a fungal microorganism that we use to raise bread and ferment beer. But yeast gets even more intimate with us than that. One variety, Candida albicans, is a living microorganism that is part of the beneficial flora that populate our bodies. Like friendly bacteria, it usually coexists peacefully with us on the surfaces of our skin and the mucous membranes of the throat, gastrointestinal tract, and, for women, in the vagina.

Beginning in 1985, the researchers took stock of the participants' intake of quercetin and other flavonoids. In five years, the researchers tracked the participants whose major source of flavonoids were tea, onions, and apples. It was found that the flavonoid intake decreased mortality from coronary heart disease and additionally decreased the incidence of the first heart attack. As expected, researchers also found that flavonoid intake was linked to a decreased risk of stroke by as much as one third of the risk factors.
