Euphorbia species contain the toxic compounds dopamine, gallic acid, hydrocyanic acid, quercetin, and saponin (Duke 1985:555). These compounds may account for the destruction of warts. The latex is exceedingly irritating when applied externally. Common to many species of Euphorbia are diterpene (phorbol) esters, which are tumor promoting (Lewis and Elvin-Lewis 1977:121). Euphorbia hirta relaxes the bronchioles but also depresses respiration and the heart (Lewis and Elvin-Lewis 1977:299). Extract of the branches of Euphorbia cf. poly-carpa Benth.

NUTRITIONAL SUPPLEMENTS • Vitamin C (1,000 milligrams two or three times a day) and a citrus bioflavonoid complex (1,000 milligrams with rutin twice a day I or quercetin (up to 500 milligrams three times a day). More absorbable forms of bioflavonoids, such as hesperidin, hesperidin methyl chalcone, naringin, grape skin extract, and winter cherry extract may be preferable (FlavoPlex-C by Interplexus of Kent, Washington, two to three capsules once a day). • Lactobacillus acidophilus and bifidus supplements (at least one capsule of a quality brand twice a day).

See Chapter Nineteen for information on their remarkable cardiovascular effects and other properties.) • quercetin is a flavonoid commonly used in treating diabetes as it inhibits aldose reductase, an enzyme involved in diabetic cataracts, retinopathy, and neuropathy. Dosage: 300 to 500 milligrams two or three times a day. Naringin, another flavonoid, also functions as an aldose reductase inhibitor. Dosage: 300 to 600 milligrams two or three times a day. • Fenugreek seeds (defatted) can decrease blood sugar as well as insulin levels, total serum cholesterol, and triglycerides.

HERBAL REMEDIES • Take quercetin (300 to 500 milligrams two or three times a day), a bioflavonoid used to relieve many allergic conditions. It helps block the release of histamine. Edema See WATER RETENTION. Endometriosis Most common in childless women between the ages of thirty and forty, endometriosis occurs when bits of uterus lining grow beyond its usual region into the fallopian tubes, on the ovaries, on uterine ligaments, even on the intestines and other abdominal cavity structures.

For example, it has been shown that some flavonoids, like quercetin, gossypol, chrysin, and apigenin, bind to a certain receptor in the brain to which benzodiazepine tranquilizers, such as Valium, usually bind. The herbs from which these compounds are obtained (such as passiflora coerulea and matricaria recutitis) have been reported in folk medicine to have sedative and pain-relieving properties. A synthetic derivative from these flavonoids has been produced that is one hundred times as potent as Valium [137].

Many compounds have been found in the bark of oak species, with tannins and quercetin perhaps the most significant in explaining ethnic uses. The tannic acid is highly astringent (Font Quer 1979:109-10). The acorns are 50% starch and contain various sugars, fat, and tannin. The galls contain up to 30% gallic and tannic acids, as well as other compounds. ¦ Ratldia (Rubiaceae) RANDIA Randia echinocarpa Sesse & Moc. ex DC. papache, Tepehuan, Tarahumara, Mayo, northwestern Mexico; kakdwari, Tarahumara; granjel, papache, Spanish Randia spp.

One particular onion-dwelling flavonoid called quercetin has been shown to help knock out heart disease in two ways. One, it helps prevent the dangerous low-density lipoprotein form of cholesterol from oxidizing, which is the process that makes it stick to artery walls. Two, it helps prevent platelets in blood from sticking together and forming harmful clots. A second group of protective compounds in onions are the same ones that make you cry—the sulfur compounds.

Opuntia ficus-indica has been found to contain the flavonoids kaempferol, luteolin, and quercetin, as well as rhamnetins and beta-sitosterol. The stem (pad) contains the most active compounds. High in mucilage, this species also has hypoglycemic or antihyperglycemic and diuretic activity. The fruit is high in carbohydrates, especially rhamnose, fructose, galactose, and glucose, as well as vitamin C.

Red wine contains powerful antioxidant flavonoids (in particular quercetin, rutin, reservatol, and catechin). White wine contains lesser amounts. These chemicals are also found in tea, onions, and apples. However, it is possible that the French paradox may also be due in part to the higher intake of vitamin E, especially in the form of sunflower seed oil. (31) Hertog et al. in Zutphen, Holland, studied 805 men aged 65 to 84 for five years [86]. They measured the total flavonoid intake, 65 percent of which came from tea, 13 percent from onions, and 10 percent from apples.

The main source of flavonoids (in this case quercetin) in the Finnish diet is apples and onions. (Finns drink little tea or red wine.) The researchers noted that apples are a poor source of vitamin C and beta-carotene. They also noted that Finns in general had a very low intake of flavonoids as compared with people elsewhere. Oddly, the benefit seemed to be gained from apples and not onions. As we have already seen, Finns, at least southern Finns, seem to react differently than do other populations [5, 174, 175]. Their very high intake of fats and alcohol may be important complicating factors.

Antioxidant flavonoids include catechin (green tea), gossypol (rice), apigenin (chamomile tea), quercetin (apples), hesperetin (oranges), and naringenin (grapefruit). Antioxidant phenols include thymol and carvacuol (thyme), ferulic acid (many herbs), gallic acid (mitgall), hydroxytyrosol (olive oil), fisetin, morin, and many others. Antioxidant polyphenols are found in oranges (as cryptoxanthin) and many other fruits, tea, coffee, chocolate, licorice, and white wine. Other related plant antioxidants include rhein (rhubarb) and aloe-emodin (aloe).

These include quercetin, rutin, and catechin. Red wine also contains a potent antioxidant—reservatol—found also in peanuts. Reservatol slows the making of fats by the liver and inhibits prostaglandin synthesis (and thus inflammation); it also prevents platelets from sticking together (a major cause of the blockage of coronary arteries leading to heart attacks). A derivative of reservatol is an ingredient in a folk medicine called kojo-kon.

Watery solutions of green tea and black tea (which both contain quercetin, myrecetin, and kaempferol) are equally effective in preventing fat oxidation in test tube experiments. These compounds also have anticancer effects in a number of tests. GARLIC. In Mediterranean countries garlic has always been regarded as a health-giving food.

Hesperidin, naringin, quercetin, and other flavonoids are almost always present in the foods in which vitamin C is found. Some practitioners recommend daily supplemental intake (up to 500 milligrams) of a bioflavonoid complex that is commonly included in some vitamin C preparations. Bioflavonoids can also be taken separately in higher doses for specific treatments. (See pages 392, 406, and 423 for discussion.) Food sources of vitamin C include primarily raw vegetables and fruits and their juices—especially fresh ones.

For example, quercetin and naringenin (found in grapefruit) together inhibit breast cancer growth more effectively than do the two used apart. These compounds are also effective at removing excess iron from the body. This is important, since iron can promote cancer and heart disease by generating toxic free radicals in the liver and heart. A single glass of grapefruit juice contains enough naringenin to increase the half-life (the time a drug or nutrient stays active in the body) of the cardiac drug nifedipine.

For the more severely affected and multiple-food-allergic patient, instead of quercetin, I usually recommend a very safe prescription drug called Gastrocrom (cromalyn sodium), to be taken fifteen to thirty minutes before meals. The contents of one or two capsules should be stirred in a small glass of warm water and taken orally. This medicine can effectively block food reactions and associated inflammation, and enable eating without as severe restrictions.2' By reducing the damage from allergic inflammation, cromalyn sodium can ultimately help the leaky intestinal mucosa heal.

Keeping LDL cholesterol in check is a good start against heart disease, but that's not all the quercetin in wine does, says Dr. Folts. It also helps prevent platelets in blood from sticking together. Indeed, a study led by Dr. Folts and his colleagues found that when red wine was given to laboratory animals, it eliminated potentially dangerous clots.
