Not long ago, American herbalists had to rely on folklore and anecdote. There was little clinical data on , and what did exist was mostly published in German. But researchers (and translators) have been busy of late, and we now have proof that herbs are viable treatments for many ailments.
“Herbs won’t replace pharmaceuticals, but the research shows that–for many conditions–herbs work well, are cheaper than drugs and cause fewer side effects,” says Mary Hardy, M.D., medical director of the integrative medicine program at Cedars-Sinai Medical Center in Los Angeles. “Herbs aren’t quite mainstream, but they’re moving in that direction. Patients are interested in them, and doctors are increasingly familiar with herb research.
“Twenty years ago, there was no integrative program at Cedars-Sinai” she adds. “Now there is. That says something” Here, then, are the proven, 55 best herbal treatments. Stick to the dose specified in the studies or on the product label. When making teas, use 1 to 2 teaspoons of herb per cup of boiling water, steeped for 10 minutes. Tell your physician about any herbs you plan on using, especially if you’re pregnant or nursing, have a chronic medical condition or take medication regularly.
(1) Aloe Vera for Burns Sometimes studies tell us what we already know. Aloe vera is the herb for minor burns, a fact that was confirmed most recently in the Journal of the Medical Association of Thailand. Keep a potted aloe on your kitchen sill; it requires no care beyond weekly watering. For minor burns, snip off a thick leaf and slit it open; scoop out the gel from the inner leaf and apply to the burn.
(2) Black Cohosh for Menopause The Algonquin Indians used black cohosh to treat gynecological ills, and it was a key part of Lydia E. Pinkham’s Vegetable Compound, sold in the 1870s to treat “female complaints and weaknesses.” In a recent German study on menopausal hot flashes, subjects were given estrogen, a Valium-like tranquilizer or black cohosh (Remifemin, two tablets twice a day). The herb, which is an option for women who can’t take estrogen, worked best. “The vast majority of studies show benefit,” says Mark Blumenthal, executive director of the American Botanical Council.
(3) Boswellia for Arthritis and Joint Injuries Did the three wise men suffer aches and pains from their long camel ride? Luckily, they had frankincense, aka boswellia, a traditional Ayurvedic medicine for arthritis and joint injuries. In a study published in Alternative and Complementary Therapies, Egyptian researchers gave people with osteoarthritis of the knee boswellia and turmeric or a placebo. After three months, the herb group showed significantly greater relief from knee swelling.
(4) Chamomile for Digestive Problems “Chamomile tea, perhaps the best-known herbal tisane, is widely employed as a digestive remedy throughout Europe, and its therapeutic use is well documented,” says David Hoffman, author of Medical Herbalism. This herb relaxes spasms of the smooth muscles and counters inflammation in the gut lining; it also has antiseptic and vasodilatory effects. Allergic reactions are possible, especially if you’re sensitive to ragweed.
(5) Chaste Tree for Premenstrual Syndrome It won’t preserve virginity, but chaste tree has hormonal effects that minimize monthly symptoms. When 1,634 German PMS sufferers took chaste tree, 93 percent reported benefit. In tests against two other popular treatments, vitamin [B.sub.6] and Prozac, the herb worked as well as the drug and better than the vitamin. “Chaste tree is the best herb for PMS,” says James A. Duke, Ph.D., author of The Green Pharmacy. “It’s safe and the studies are convincing. “Just be patient: It can take three months to experience benefit. Some women report stomach distress, headache and increased menstrual flow.
(6) Coffee for Athletic Stamina The caffeine in coffee or tea stimulates not only alertness (and jitters and insomnia), but also athletic performance. Korean researchers at the Institute for Elderly in Seoul asked athletes to ride stationary cycles until they felt exhausted–before and after drinking the equivalent of one tall Starbucks coffee. After their java break, they were able to ride significantly longer.
(7) Coffee for Pain Relief Anacin and Excedrin claim that their “extra ingredient” provides greater pain relief. What is it? Caffeine. Many reports, including one in the Archives of Internal Medicine, have shown that adding about 65 milligrams of caffeine to aspirin, ibuprofen or acetaminophen increases pain relief by around 40 percent. Caffeine blocks pain perception, has pain-relieving action, and elevates mood, which also helps minimize pain. Next time you have a headache, wash down your favorite pain pill with coffee or tea for more relief.
(8) Coffee as a Decongestant in Colds, Flu and Asthma Caffeine opens narrowed bronchial tubes, according to Joe and Teresa Graedon, authors of The People’s Pharmacy. According to a report in the Annals of Epidemiology, the odds of experiencing current asthma symptoms were reduced 29 percent for subjects who drank coffee on a regular basis when compared with non-coffee drinkers.
(9) Cranberry for Urinary-Tract Infection Cranberry prevents bacteria from sticking to the bladder wall long enough to cause an infection. Finnish researchers divided 150 recurrent UTI sufferers into three groups. One drank cranberry juice (50 milliliters a day). Another took Lactobacillus. The third took nothing. After six months, 36 percent of the no-treatment group and 39 percent of the Lactobacillus group reported at least one recurrence. Of the juice drinkers, only 16 percent had recurrences. Other options are dried cranberries (Craisins) and cranberry-extract capsules. “I recommend cranberry for UTI,” Duke says. “But if you drink the juice, you have to drink a lot. It’s usually easier to munch on the dried berries or take capsules.”
(10) Echinacea for Colds and Flu The root of this daisy-like flower revs up the immune system. According to an analysis by University of Wisconsin researchers, in eight of nine studies evaluating echinacea for upper-respiratory infections, the herb reduced symptoms and accelerated recovery compared with placebos. “As soon as I feel a cold coming on, I take it–and my cold is mild and brief,” says Duke. Echinacea is available in teas and capsules, though most herbalists prefer tinctures. Liquid echinacea products may cause temporary, harmless numbing or tingling of the tongue; minor stomach upset is possible with tinctures. To manage your while the Echinacea kicks in, you can use an OTC medication. While these medicines won’t cure or shorten the duration of your illness, they can help get you back on your feet again.
(11) Evening Primrose Oil for Lowering Cholesterol Evening primrose seeds contain an oil with a high concentration of compounds rarely found in plants: essential fatty acids, specifically gamma-linolenic acid. In one study, reported in The Review of Natural Products, 79 people with high cholesterol took 4 grams of Efamol every day for three months (which provides about 320 mg of GLA), and their average cholesterol level fell 31.5 percent. The suggested dose for evening primrose oil starts at 1-gram gelcaps twice or three times a day. High cholesterol requires professional care, so consult your physician about GLA.
(12) Evening Primrose Oil for Rheumatoid Arthritis The EFAs in EPO are also a powerful anti-inflammatory. University of Pennsylvania researchers gave 37 arthritis sufferers borage oil (which contains GLA) or a placebo, The placebo had no effect, but the herb group reported 45 percent less pain with no side effects. Other studies utilizing GLA obtained similar results. Rheumatoid arthritis requires professional care, so consult your physician about GLA.
(13) Feverfew for Migraine Prevention British scientists at the University of Exeter analyzed six studies of feverfew, concluding that the herb significantly reduces the frequency of migraine occurrence. “In my experience,” Duke says, “feverfew prevents migraines in about two-thirds of those who use it consistently.” Dosage is generally 50 to 150 mg per day of powdered leaves.
(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.
(28) Ginseng for Diabetes Ginseng also reduces blood-sugar levels. In a study published in Diabetes Care, 30 subjects newly diagnosed with diabetes were given ginseng extract (100 or 200 mg a day) or a placebo, with the ginseng groups showing lower blood-sugar levels. Other studies concur. Diabetes requires professional treatment; consult your physician about ginseng.
(29) Ginseng for Erectile Dysfunction According to a review of studies at Yale University, ginseng boosts the body’s synthesis of nitric oxide. As NO increases, so does the likelihood of erection. In a report in the Journal of Urology, Korean researchers gave 45 men with erection impairment a placebo or ginseng (900 mg three times a day). Those taking the herb experienced significant erection improvement.
(30) Ginseng for Low Sperm Count At the University of Rome, Italy, researchers gave ginseng (4 grams a day) to 30 men suffering from low sperm counts. Three months later, the subjects’ counts almost doubled, from an average of 15 million/ml to 29 million/ml.
(31) Goldenseal for Digestive-Tract Infections Goldenseal, an herbal antibiotic, is often marketed in combination with echinacea as a treatment for infections, but it is effective only in the digestive tract, not for colds or flu. At the University of Illinois in Chicago, researchers tested goldenseal against H. pylori, the bacteria that cause ulcers, and the herb inhibited bacterial growth. For GI infections (ulcer, food poisoning, infectious diarrhea, etc.), ask your doctor about using goldenseal in addition to medical therapies.
(32) Hawthorn for Congestive Heart Failure In heart failure, the heart keeps beating, just not as forcefully as it should; people with the condition become exhausted from minor exertion. Many studies show that hawthorn stimulates fatigued hearts to beat more normally. In a study published in Phytomedicine, German researchers gave hawthorn (240 mg a day) or a placebo to 40 people with heart failure. Three months later, the hawthorn group was able to exercise significantly longer. “We reviewed much of the published research on hawthorn recently,” Blumenthal says, “and 13 of 14 studies showed benefit in heart failure.”
(33) Hibiscus for Hypertension Hibiscus is the trumpet-shaped, tropical flower that puts the color in Red Zinger tea. A report in the Journal of Ethnopharmacology found that 12 days of drinking hibiscus tea (2 teaspoons per cup of boiling water several times a day) lowered systolic and diastolic blood pressure by 11 percent. High blood pressure requires professional care; ask your doctor about adding hibiscus to your treatment plan.
(34) Horse Chestnut for Varicose Veins “Mainstream medicine offers only support hose and surgery,” says Blumenthal, “but standardized horse chestnut seed extract has shown efficacy in most clinical trials.” At the University of Heidelberg, Germany, 240 sufferers of newly visible varicose veins were treated with compression stockings or horse chestnut (50 mg aescin twice a day). After 12 weeks, both groups reported equal relief. Off the tree, horse chestnuts are poisonous, but commercial extracts are detoxified and safe.
(35) Horsetail for Skin Healing Before steel wool and abrasive cleansers, this herb helped scour pots and pans. Today it’s used to heal the skin. A Spanish study published in Revista de Enfermeria showed that horsetail speeds the healing of wounds; it’s also used in skin-care products.
(36) Lavender for Anxiety Lavender flowers are an age-old remedy for anxiety. British researchers at the University of Wolverhampton had women add lavender oil or a placebo to their bath water. Bathing by itself is calming, but in this study, a bath infused with lavender oil significantly reduced anger, frustration and negativity. Use a handful of lavender flowers, or buy lavender oil and add several drops to your bath. Ingesting lavender oil is toxic; keep it away from children.
(37) Lemon Balm for Relaxation The 17th-century English herbalist Nicholas Culpeper wrote that lemon balm drives away all melancholy. That’s an overstatement, but science has shown that lemon balm is tranquilizing. The herb and its oil have been used in Alzheimer’s care units to calm those who are agitated. To decompress after a tough day, try a cup of lemon-balm tea; for extra benefit, mix with chamomile.
(38) Lemon Balm for Herpes Lemon balm has antiviral action. As reported in Phytomedicine, German researchers gave 66 people in the early stages of herpes simplex labialis outbreaks lemon-balm cream or a placebo. The herb group had milder outbreaks that healed faster. Lemon balm is the active ingredient in the herpes treatment Herpalieve. “If you have herpes,” Duke says, “drink lemon-balm tea. If you have an outbreak, apply lemon balm to the sore.”
(39) Licorice for Sore Throat In a study in the Journal of Alternative and Complementary Medicine, researchers gave either a placebo or Throat Coat, a licorice tea from Traditional Medicinals, to 60 sore-throat sufferers 4 to 6 times a day for seven days; the tea tipplers reported significantly less pain on swallowing. Add a teaspoon of chopped or powdered root to a beverage tea, and feel relief almost immediately.
(40) Milk Thistle for Liver Health Silymarin in milk thistle seeds has a remarkable ability to protect the liver. This herb has been shown to help treat hepatitis and alcoholic cirrhosis, and it’s been found more effective than traditional medicine at treating “deathcap” mushroom poisoning. “In our analysis,” Blumenthal says,” 19 of 21 studies support milk thistle seed extract for liver conditions.” Because most drugs are metabolized through the liver, many herbalists recommend silymarin for anyone who takes liver-taxing medication.
(41) Papaya for Herniated Disks Papaya has been used by Caribbean Indians to treat skin wounds and infections and by the Japanese to treat digestive disorders. In 1982, the Food and Drug Administration approved injections of the papaya enzyme chymopapain to dissolve cellular debris in herniated or slipped vertebral disks in the back. Allergic reactions are possible.
(42) Peppermint for Indigestion In ancient Greece, people chewed a sprig of mint after feasts to settle the stomach, a tradition that evolved into our after-dinner mints. German researchers gave 118 adults with persistent indigestion a standard drug (cisapride) or twice-daily capsules of enteric-coated peppermint oil (90 mg) and caraway oil (50 mg), another traditional stomach soother. (The enteric coating allows the capsules to survive stomach acid and release their oil in the small intestine, where non-heartburn indigestion develops.) Four weeks later, the drug and the herb blend produced the same relief. If you use herbal oils, do not exceed the recommended dose, and keep them away from children. You also can brew a peppermint tea, and add a teaspoon of chopped caraway to meals. “When I get indigestion,” Duke says, “I go to the garden, pick some peppermint, chew some leaves, and make tea. It works for me.”
(43) Peppermint for Irritable Bowel Syndrome IBS involves persistent abdominal cramps, bloating, flatulence, and diarrhea or constipation. British researchers at the University of Exeter analyzed five studies of peppermint oil as a treatment, and found that it provided benefit. (See the previous item for options and cautions.)
(44) Psyllium for Diarrhea and Constipation Psyllium is a tiny seed that contains mucilage, a soluble fiber that swells on exposure to water. For diarrhea, psyllium can absorb excess fluid in the gut. For constipation, psyllium adds bulk to stool, which presses on the colon wall and triggers the nerves that produce the urge to go. You may find psyllium at health-food stores, but it’s easiest to take Metamucil, which is psyllium with flavoring. When using psyllium, drink plenty of water. Allergic reactions are possible.
(45) Red Pepper for Pain Relief Capsaicin, the compound that gives red pepper (cayenne) its fiery flavor, is a potent topical pain reliever, according to the Handbook of Nonprescription Drugs. When rubbed on the skin, it causes mild superficial burning. But that sensation desensitizes nearby pain nerves, and soothes pain in deeper tissues. Capsaicin is the active ingredient in several over-the-counter pain-relieving creams, such as Capsin, Zostrix and Pain-X.
(46) St. John’s Wort for Depression For mild depression, St. John’s wort often works as well as Prozac and Zoloft, but with fewer side effects. “We recently concluded a comprehensive review of the scientific literature on St. John’s wort, and 21 of 23 studies support it for mild-to-moderate depression,” says Blumenthal. Studies showing benefits have used 600 to 1,800 mg a day; most have used 900 mg a day. Stomach upset is possible, and St. John’s wort interacts with many drugs, including possibly reducing the effectiveness of birth-control pills. Depression requires professional care; ask your physician about St. John’s wort.
