(14) Flaxseed for Menopausal Discomfort
Safety concerns have reduced the number of women on hormone replacement therapy, but flaxseed is rich in phytoestrogens (plant estrogens) that can take the heat out of hot flashes. At Laval University in Quebec, Canada, researchers gave 25 menopausal women HRT or flaxseed (1.4 ounces per day, mixed into food). After six months, flaxseed relieved hot flashes as effectively as HRT.
(15) Flaxseed for Osteoporosis
Because flaxseed is a natural hormone replacement therapy, it also mimics HRT's bone-preserving ability. Oklahoma State researchers gave a placebo or flaxseed (1.3 ounces per day) to 38 postmenopausal women for 14 weeks, and measured blood and urine for markers of bone loss and regrowth. The flaxseed group showed decreased bone resorption and calcium excretion, indicating reduced bone loss.
(16) Garlic as an Antibiotic
From ancient times through World War I, garlic has been used to treat the wounded. During the 1920s, researchers at Sandoz Pharmaceuticals in Switzerland isolated garlic's antibiotic compound, alliin, which has no medicinal value until the herb is chewed, chopped or crushed. Then an enzyme transforms alliin into a powerful antibiotic called allicin. Modern antibiotics are more potent and easier to take (just try chewing a dozen raw cloves), but if you're concerned about ulcers, use more garlic in your diet. Researchers at the University of Washington have shown that garlic kills H. pylori, the bacteria that cause ulcers. Raw garlic has the most antibiotic potency, but garlic still has benefits when cooked. "I use lots of garlic in cooking," Duke says, "for reasons of taste and health."
(17) Garlic for Cholesterol Control
Researchers at New York Medical College in Valhalla analyzed five studies and found that one-half to one clove of garlic per day reduces cholesterol by 9 percent. If you'd rather not eat fresh garlic every day, garlic supplements, including "deodorized" brands. have a similar effect. (Supplements with proven benefit include Kwai and Kvolic.) "Garlic doesn't work as well as the statin drugs," says Blumenthal, "so if your numbers are really high, you may need medication. But if your cholesterol s just mildly elevated or if it's normal and you want to keep it that way, garlic definitely helps." Garlic can impair blood clotting; if you notice increased bruising, stop taking it. and consult your physician.
(18) Garlic for Cancer Prevention
Garlic reduces the risk of several cancers. In the long-term Iowa Women's Health Study. researchers followed 41,837 middle-aged women. Subjects who ate the most garlic had the lowest risk of colon cancer. A few cloves a week cut risk by 32 percent and greater intake decreased risk even more While fruit and vegetable consumption in general helps prevent cancel in this study, garlic yielded the greatest preventive benefit of all the plant foods analyzed. Other studies have shown that garlic helps lower risk for prostate and bladder cancers.
(19) Ginger for Motion Sickness
In ancient China, sailors chewed ginger root to prevent motion sickness and modern studies have confirmed that ginger prevents nausea and vomiting. Danish scientists at Svendborg Hospital observed 80 naval cadets in heavy seas and found that those who took ginger experienced 72 percent less seasickness than a placebo group. Take a 1-gram capsule of powdered ginger root about an hour before you embark, and another every two hours or as needed (without exceeding 10 grams a day) during a journey, Ginger's only side effect is occasional minor heartburn. "t use ginger myself." Duke says, "It works for me."
(20) Ginger for Morning Sickness
Speaking of nausea, ginger also assists in preventing morning sickness. In a stud'. published in Obstetrics and Gynecology, researchers at Thailand's Chiang Mai University gave 70 nausea-plagued pregnant women ginger powder (1 gram a day) or a placebo. In the latter group, 28 percent reported relief But in the ginger group, the figure was 88 percent, use the dose given in the study, or brew a tea using 2 teaspoons of freshly grated root per cup of boiling water.
(21) Ginkgo for Alzheimer's Disease
The big study was published in 1997 in the journal of the American Medical Association: Researchers n a multicenter study gave 202 people with Alzheimer's either a placebo or ginkgo extract (120 mg a day). A year later, the ginkgo group retained more mental function, and subsequent studies have corroborated this finding. Ginkgo Improves blood flow around the body--including through the brain. It's safe. but it has anticoagulant properties, so increased bruising is possible.
(22) Ginkgo for Mental Acuity
Beyond its benefits for Alzheimer's, four recent studies show that ginkgo improves mental function in people who are cognitively normal, In a study published in Phytotherapy Research. 31 health, adults, ages 30 to 59, received ginkgo (120 to 300 mg a day) or a placebo, The herbs significantly improved several measures of memory. Buy a standardized extract and take 120 to 240 mg a day.
(23) Ginkgo for Erection and Libido Problems
Ginkgo improves blood flow into the genitals. In a study published in the Journal of Urology, 60 men with erection problems caused by narrowed arteries and impaired blood flow to the penis were given ginkgo (60 mg a day); after six months, half had regained erection ability. When researchers at the University of Hawaii and Stanford University tested ArginMax, a sexual-enhancement supplement that contains ginkgo, ginseng and L-arginine, 80 percent of the male subjects had improved erection function, while 74 percent of the female subjects reported more libido, less dryness and greater frequency of orgasm.
(24) Ginkgo for Anti-Depressant-Induced Sex Problems
An enormous number of Americans take antidepressants, The relief comes at a price: a substantial risk of libido loss erection impairment, vaginal dryness and inability to reach orgasm. Investigators at the University of California at San Francisco gave ginkgo (209 mg a day) to 63 people suffering from antidepressant-induced sex problems. The herb helped 91 percent of the women and 76 percent of the men to return to normal sexual function
(25) Ginkgo for Altitude Sickness
Traveling from a low elevation up to the mountains often produces symptoms of altitude sickness, such as headache, sluggishness and excessive thirst, due to the decrease in available oxygen. (Over a few days. the body makes more red blood cells, which boosts oxygenation of the blood.) Researchers at the Hopital de Chamonix in France gave 44 mountaineers ascending the Himalayas ginkgo (80 mg twice daily) or a placebo. In the latter group, 82 percent developed respiratory problems related to altitude sickness, but among the ginkgo users, the figure was only 14 percent.
(26) Ginseng for Athletic Stamina
Many athletes take ginseng as part of their training. In a study published in Clinical Therapy, Italian researchers gave 50 physical education teachers a placebo or ginseng (with some vitamins and minerals), and then had them run on a treadmill, Hearts and lungs in the ginseng group worked more efficiently, and those subjects' stamina increased significantly, Ginseng is safe, but it does have anticoagulant action. so increased bruising is possible.
(27) Ginseng for Immune Enhancement
Many studies show that ginseng revs up the immune system. Scientists at the University of Milan. Italy, gave ginseng (100 mg a day) or a placebo to 227 people. A month later. everyone received a flu shot (which does not kill the flu virus. but rather stimulates the immune system to resist infection). In the placebo group, 42 people got the flu, but in the ginseng group, the figure was just 15, demonstrating that ginseng enhanced immune response to the shot.
