St. John's Wort -LATIN NAME: Hypericum perforatum FAMILY NAME: Clusiaceae http://www.mothernature.com/Library/bookshelf/Books/54/13.cfm St. John's wort is a happy plant. Just looking at its yellow, star-shaped flowers is enough to lift my spirits. But in the winter of 1998, I reached for this weedy perennial for more than its aesthetic qualities. Knowing the herb is a proven antidepressant as well as a potential treatment for a variety of ailments, I supplemented with St. John's wort capsules four times a day to shake my winter doldrums. Optimistic and energetic by nature, I typically work 12-hour days at my computer, walk daily in and around my six-acre herbal vineyard, and travel the world to forage for plants or talk about them. One of my associates jokes that she hardly has the energy to keep up with me, even though her years tally far fewer than my 70. Thankfully, I have never suffered from debilitating, down-and-out depression. But every fall, as the daylight hours wane, my mood fades too. I lose my usual enthusiasm. I feel out of sorts. Looking back, I think I've always been less motivated in fall and winter. As a boy living in the South, where sunlight is plentiful, at least in summer, this was not a problem for me. As an adult living in Maryland, farther from the equator, my annual dose of sun is not as potent. And I sense the subtle effects. In recent years, science has given a name to this common human experience: seasonal affective disorder, or SAD. While it is a form of depression--affecting 10 million people in the United States, the National Institute of Mental Health reports--it usually is mild and short lived. When there is less daytime, our brains don't get as much light by way of our eyes. That translates into fewer nourishing " neurochemicals " that fuel our sense of well-being. Annual jaunts to Peru and other South American climes are my favorite " antidote " for the winter blues. But in 1998, I had no trip planned. So, instead, I took standardized hypericum capsules for the first time. After all, years of research and conversations with colleagues and friends had convinced me hypericum was not to be ignored. Now, I consider it part of my herbal arsenal, a kind of vacation in a bottle, when a trip to the Amazon is out of the question. What St. John's Wort Is and What It Can Do You've probably heard something about St. John's wort & shy; & shy; or St. Joan's wort, as my herbalist friend Susun Weed, author of Breast Cancer? Breast Health! The Wise Woman Way, dubs it. Maybe you know of someone who claims this herb--in capsule form, tincture, or tea--has helped her ward off SAD or full-blown depression. Hypericum's been much more popular in the United States since 1997 when a national television program aired a report on the herb's reputed antidepressant properties. The plant & shy; & shy;and products made from it & shy; & shy;became downright hard to find. Now, it's available everywhere & shy; & shy;in health food stores, pharmacies, and supermarkets and in products from well-known vitamin manufacturers. Even in potato chips. Its reputation is growing beyond that of an antidepressant. Some of the phytochemicals in St. John's wort are believed to be helpful in staving off HIV, the virus that causes AIDS, and in the topical treatment of herpes viruses and first-degree burns, cuts, and wounds. They show promise, too, in easing the pain and swelling of arthritis and fibromyalgia and the discomfort associated with menopause and perimenopause as well as other medical conditions. That's why St. John's wort is among Duke's Dozen. This pretty perennial is native to Europe, where its use dates back 2,000 years. In their book, Rational Therapy--A Physician's Guide to Herbal Medicine, Volker Schulz, Rudolf Hansel, and Varro E. Tyler say it grows wild as a weed in Asia and North and South America. I find it grows in most temperate climates, especially in dry sunny locations. Some people claim the herb gets its name from St. John's Day (June 24), when it typically blooms, although there are other explanations. Wort, incidentally, has no relation to the unsightly skin growth (spelled warts) that toads are infamous & shy; & shy; incorrectly--for passing along. It simply is old English for " plant. " In earlier times, the herb was said to expel evil spirits in those who ingested it. The Latin name, Hypericum, is based on the Greek word for " over an apparition. " DR. DUKE'S NOTES In some parts of the country, St. John's wort is better known by its common name, klamath weed. In California, where cattle have become photosensitive after grazing on large amounts of klamath, a movement has sprung up to eradicate the wild weed. There is even a monument, erected by the U.S. Department of Agriculture, to indicate success in biological control of the klamath weed in California. And, in 1998, California was having trouble supplying the demand for St. John's wort. Emotional Health Schulz, Hansel, and Tyler suggest that Paracelsus, the sixteenth-century Swiss physician and alchemist, knew of hypericum's effectiveness in treating psychiatric conditions and that German poet-physician Justinus Kerner reported its use in mood disorders in the early nineteenth century. In more recent years, though, the herb was pushed aside in favor of synthetic antidepressants. Then, in the late twentieth century, reports of its usefulness began to pour in once again. Most came from Germany, where the value of herbal medicines has been more readily embraced. In 1984, Commission E (a German panel of experts roughly equivalent to the U.S. Food and Drug Administration) approved hypericum for relief of mild to moderate depression and anxiety associated with it. As study after study cited its effectiveness, St. John's wort became the leading antidepressant in Germany. There, it outsells even Prozac, the synthetic pill Americans began gobbling up in the late 1980s. We're slow to catch on in America. Most of the studies showing hypericum's value as an antidepressant have been done abroad. In 1996, the British Medical Journal published an overview of 23 clinical studies, involving more than 1,700 patients. It concluded that hypericum has antidepressant properties, particularly in mild to moderate cases. And it said the herb was more effective than a placebo and just as potent as prescription antidepressants, without their side effects. I'm almost positive I'm improving my emotional health by keeping St. John's wort on hand and using it when I feel the need. Oddly, this herb has gained so much attention overseas, Americans often are surprised when I tell them hypericum grows on its own in each of the 50 states. Early colonists likely brought it with them, either intentionally or by accident. Perhaps the tiny seeds hitched a ride on some food or other supply the settlers carried to the New World. Thanks to our ancestors, you might have your own supply of this wonderful herb just down the road a bit or on your own soil, as I do. Although I never purposely cultivated St. John's wort until I established my Green Farmacy Garden in 1998, I suppose you could say it grew on me. The weed has a mind of its own in my garden, popping up wherever it likes, to heights of one to two feet, or three feet in an organic garden. HERB LORE AND MORE Native Americans also turned to the healing qualities of St. John's wort, which early colonists brought to the New World. Interestingly, their uses are not the ones considered most effective today. The Menominees compounded it with blackcap raspberry root and used it for kidney troubles. A compound containing the root was used to treat tuberculosis. The Meskwakis applied a powder of the boiled root of St. John's wort to draw poison from the bite of the water moccasin. The Cherokees, too, chewed on the root, swallowing a portion and applying the rest as a poultice for snakebites. The Cherokees took infusions of hypericum for fever and sniffed the crushed plant as a remedy for nosebleeds. Infusions also were used for bloody flux and bowel complaints. A compound decoction was taken to promote menstruation. The Seminoles used infusion of roots for rat sickness and blocked urination and bowels. The Choctaw relied on a decoction of root for colic and as a wash for sore eyes. The Miwok Indians depended on a decoction of the plant as a wash for running sores. It was thought to be a dermatological aid, perhaps because of its anti-inflammatory and antiviral properties, and it was used to break fevers and counteract venereal disease. A Bountiful Garden and a Beautiful Bouquet My wild-but-welcome St. John's wort includes Hypericum perforatum and Hypericum punctatum, 2 of about 400 species of the plant. My two happen to be among seven I studied in my years with the U.S. Department of Agriculture. All proved rich in at least one major active ingredient, hypericin, the focus of many studies. Each year, around the third week of June, my plants bloom on schedule and continue to flower sporadically through first frost. (They may lapse into quiescence during droughts, only to liven up after the rains return.) It's as if they know I expect them. Their yellow petals are speckled with orange and reddish dots that ooze a purplish oil when pinched. Some herbalists liken the dots--where the active ingredients reside--to the pores of St. John's skin. When the flowers are steeped in oil, the " blood " in the pores moves into the oil. My Hypericum punctatum seems to have more of the purplish compounds. Just crushing it stains my fingers. Sometimes, on summer strolls around my home, I gather the plants' flowering tops--so rich in phytochemicals. I could use them to make my own extract but generally prefer to take standardized capsules. That way, I know I'm getting the same amount of active ingredients with every dose--something I can't be sure of with the plants. Just like humans, each one of them is chemically unique. St. John's wort also makes a beautiful bouquet. You probably can find the plants in summer at your local greenhouse. Although these commercially grown plants won't be as medicinally active, all St. John's wort seems to contain an aromatic called cineole. In studies, large quantities of cineole enabled rats to zip through a maze more rapidly, whether the compound was inhaled, applied to their skins, or force-fed to them. Maybe a mere whiff of these mildly scented blooms can help us get happy. Why not place a pretty bouquet on a dining table or nightstand? DR. DUKE'S NOTES You can buy potato chips and other snack foods sprinkled with St. John's wort. They may taste good and likely won't hurt you. Unfortunately, they probably don't have therapeutic value, because they don't contain enough of the herb to make a difference. How St. John's Wort Can Help St. John's wort contains dozens of active ingredients, such as hypericin, pseudohypericin, protohypericin, and hyperforin. Throughout history, myriad external and internal uses have been reported. Here are the ones I believe are the most scientifically sound: Burns, cuts, and other wounds. Modern science backs up some of the folklore surrounding hypericum, including its ability to promote healing on our skin, not just underneath it. Commission E has approved the topical use of St. John's wort oil for primary and secondary blunt and sharp injuries and for burns, skin damage caused by heat, caustics, electricity, or radiation. Hypericum is both an anti-inflammatory and antibiotic, which may help prevent infection. One study in Germany showed hypericum ointment speeded healing and lessened the severity of scarring. Weed says the oil also reduces skin damage from radiation treatments. Women who applied the oil before and after treatments report their skin stayed healthy and flexible, even after dozens of exposures. Some suggest it may quicken healing from sunburn. Depression. According to the World Health Organization, depression affects 3 to 5 percent of people. It's characterized by flagging mood, lack of interest in normally pleasurable activities, disturbed eating and sleeping patterns, low self-esteem, indecisiveness, irritability, fatigue, and hopelessness. In recent years, science has begun to shed light on depression--that its causes are environmental and biochemical, and that often it runs in families. We also have a new understanding of how depression occurs: through an imbalance in neurotransmitters, or feel-good chemicals such as serotonin, dopamine, and norepinephrine, which regulate mood. A CASE IN POINT Kimberly's Story Can St. John's wort boost mood when combined with synthetic antidepressants? The major pharmaceutical makers may not want to know. But plenty of folks who suffer from depression tell me they do--and some forward-thinking physicians are helping their patients find combinations that work. Kimberly B., a fortysomething career woman in Virginia, who asked that her real name not be used, has fought mild but chronic depression since she was a teenager. " I thought I was lazy, until I learned in my late twenties what depression was, " she says. Kimberly says talk therapy helped her to " see differently, " to view life's glass as half-full and not half-empty. She learned that depression could be hereditary. " A couple of my cousins have bipolar disorder, " she says. " I think a couple of relatives struggled with alcoholism. They drank to deal with their depression. " Kimberly asked her doctor about synthetic antidepressants. " I wanted to know if I could feel better, the way normal people feel, " she says. She tried commonly prescribed dosages of Prozac, then Zoloft, and then Paxil. But the side effects--nervousness, agitation, and irritability--wouldn't pass. Finally, with her doctor's help Kimberly settled on a " baby dose " of Luvox, a selective serotonin reuptake inhibitor (SSRI) used to treat obsessive-compulsive disorder and depression. Still, she says, the benefits seemed small. Then, in 1997, Kimberly read the news reports about St. John's wort, and with her doctor's okay, began taking 300 milligrams containing 0.3 percent hypericin three times a day, in addition to the Luvox. (Note: I do not recommend combining hypericum with synthetic antidepressants without your doctor's approval.) Kimberly says she noticed the effect almost right away. " In fact, by about the third day of using both, I felt overstimulated, so I cut back on the Luvox to every other day. Sometimes, I skip a dose or two of the St. John's wort. Otherwise, I haven't had any problems. I don't avoid any particular foods and, generally, I feel good. " This newfound knowledge has led to pharmaceuticals that target specific brain chemicals. One class of antidepressants called monoamine-oxidase inhibitors, or MAOIs, help raise the brain's supply of norepinephrine and dopamine. A newer class, selective serotonin reuptake inhibitors, or SSRIs, such as Prozac and Zoloft, ensure an abundance of serotonin. While studies show these Food and Drug Administration (FDA) approved drugs are effective for many, there is a price to pay--not only in dollars at the pharmacy but in side effects including dizziness, fatigue, dry mouth, constipation, and sexual dysfunction. Further, people taking the MAOIs must avoid certain foods and medications that interact with the drugs. In the United States, Prozac is the best-selling antidepressant. But in Germany, about 200,000 prescriptions a month are filled for just one brand of St. John's wort, compared to about 30,000 a month for Prozac, says Varro E. Tyler, Ph.D., Sc.D., professor emeritus of pharmacognosy at Purdue University. In German studies involving 3,250 people, 80 percent found partial or complete freedom from depressive symptoms, Dr. Tyler says in " The Honest Herbalist--The Secrets of Saint-John's-Wort, " published in Prevention magazine. DR. DUKE'S NOTES While St. John's wort has been proven effective against unipolar depressions, evidence does not support its use in treating bipolar disorder, a condition in which sufferers " cycle " between depression and euphoria. In the United States, researchers are only beginning to study the herb's medicinal value. A three-year National Institute of Mental Health study at Duke University in North Carolina is comparing St. John's wort with Zoloft, or sertraline, the silver bullet in pharmaceutical treatment of depression in this country. I am, like many, eager to see the results. These university trials satisfy something I have been urging for a decade: that new studies on pharmaceuticals compare them not only with placebo but also with a more promising herbal alternative. I'd like to see the FDA require that for every pharmaceutical so that we can see how the herbal remedy compares with the synthetic drug. But the FDA doesn't oversee herbal products, and there's little financial incentive for big drug manufacturers to test herbs, because they can't patent them. So my plea for mandatory comparisons with herbal alternatives as well as placebo remains unanswered. But the studies at Duke (no relation to myself) are at least one start in the right direction. You'll most often see hypericin touted on St. John's wort product labels in the United States. But look for hyperforin, too. In Germany, newer studies are focusing on that chemical's action in the treatment of depression. Herpes. St. John's wort may have antiviral benefits when applied topically to the oozing, painful blisters of genital herpes. The contagious viral infection affects about 45 million Americans, according to the National Institute of Allergy and Infectious Diseases (NIAID). Herpes simplex II typically causes genital herpes, which is spread mainly through sexual contact with someone who has the virus. It lies dormant in the body between outbreaks. While oral and topical treatments can help reduce the number of outbreaks and their severity, there is no cure. St. John's wort contains proven antivirals that can help speed healing when applied topically. It also can help heal cold sores and fever blisters caused by herpes simplex I, as well as the blisters of its cousins, chickenpox and shingles (varicella-zoster). Shingles afflicts about 20 percent of adults who suffered a nasty, itchy bout of chickenpox in their earlier years. It is most common in people over 50. This virus, too, hides out in the body. When it erupts--often as the result of illness or stress--it causes pain and a blistering rash. The pain may linger for years after the visible sores have healed. Hypericum contains analgesic properties that may help to quell the pain. If I had shingles, I would add a bit of capsaicin topically to my St. John's wort--but only after any open sores had healed. Studies in the early 1990s showed hypericin is active against herpes simplex I and II. Herbalist Susun Weed also believes hypericum's antiviral powers pass through the skin and into the nerve endings, preventing and checking a variety of problems. She suggests hypericum internally (25 drops tincture) and externally, maybe every four hours, for shingles, cold sores, and genital herpes. FROM MY SCIENCE NOTEBOOK In Europe, hypericum has a long history as a treatment for depression, anxiety, and unrest. Research shows it boosts feel-good brain chemicals such as serotonin, dopamine, and norepinephrine. For many years, it was believed hypericum acted primarily as a monoamine-oxidase inhibitor, or MAOI, enhancing dopamine and norepinephrine. The warning was given to avoid alcohol, smoked or pickled foods, and certain medications for allergies and colds, which might interact with hypericum, as with synthetic MAOIs. Now, it appears the hypericum link was overplayed. My friend Jerry Cott, Ph.D., chief of the Pharmacologic Treatment Program at the National Institute of Mental Health, says the MAOI role is minor. It is more likely, as so often found in the plant world, that the compounds in St. John's wort work in synergy. They attack their opponent together, like a disciplined basketball team headed for the championship. Consumers are likely to experience fewer side effects with the herbal remedy because of the shared actions of the compounds, says Varro E. Tyler, Ph.D., Sc.D., professor emeritus of pharmocognosy at Purdue University. Newer research on hypericum, for example, shows it also acts as a selective serotonin reuptake inhibitor (SSRI), increasing the mood-enhancing brain chemical serotonin. I believe the empirically proven herbs are milder and safer because of this synergy. And their therapeutic effects may be more complete. HIV/AIDS. The NIAID says as many as 900,000 Americans may be infected with human immunodeficiency virus, or HIV. It's the virus that causes AIDS, a major worldwide epidemic, first reported in the United States in 1981. The virus kills or cripples the immune system's T-cells--the good guys--and leaves its victims unable to fight infection and certain cancers. They become susceptible to opportunistic infections, such as cytomegalovirus and herpes. In healthy people, the microbes that carry such infections don't usually cause illness. For people with HIV, they can be deadly. HIV is passed along most commonly by sexual contact with an infected partner. The sharing of needles and syringes or contact with infected blood also can spread it. Mothers can transmit the virus to their babies during pregnancy or birth, NIAID says. Some people have flu-like fever, headache, and fatigue a month or two after exposure. Severe symptoms may not occur for a decade or more. As the immune system weakens, signs such as swollen glands and weight loss begin to show. In advanced stages, HIV is categorized as AIDS. The virus can be detected by blood tests. Standard treatments for HIV/AIDS include drugs such as AZT that interrupt an early stage of virus replication, slowing the virus in the body and delaying the onset of infections. Other drugs called protease inhibitors, such as saquinivir, interrupt the virus at later stages. Because HIV can become resistant to the drugs, often they are used in costly combinations, or drug " cocktails. " These cocktails can run as high as $18,000 a year. They require extreme diligence on the part of the patient, and they are not without side effects--nausea, diarrhea, and gastrointestinal disturbances among them. Patients must also be alert to signs of interaction with other drugs that can result in serious side effects, the NIAID acknowledges. DR. DUKE'S NOTES Is it a placebo or is it hypericum? Clinical studies show a strong relationship between placebo pills and mood enhancement. In other words, people who think they are receiving medication may feel better, even if the pill is a dud. I'd rather " fool " myself with an herb than a costly pharmaceutical and the side effects that go with it. If I suffered from HIV/AIDS, I would also try the less expensive, safer herbal alternatives, including St. John's wort. I first became curious about its role against HIV in the early 1980s. Gordon Cragg, Ph.D., at the Natural Products Branch of the National Cancer Institute (NCI), called and asked where we might be able to find hypericin. " In my garden, " I told him. But it was September, past the plant's flowering season. Daniel Meruelo, Ph.D., professor of pathology at New York University School of Medicine, wanted to examine the potential antiretroviral activities of hypericin in clinical trials. The AIDS connection was new to me, and exciting. The following spring I was able to supply them with hypericum. Dr. Meruelo was looking at hypericin in test tube studies, especially when combined with ultraviolet light. As with certain cancer treatments, researchers direct the tiny flashlight-like rays to hot spots where the virus is. Dr. Cragg says hypericin itself did not appear to be the silver bullet in the NCI AIDS screen, but the work continues. Hypericum contains many ingredients that may help slow HIV. Dennis V.C. Awang, of the American Botanical Council Advisory board, has noted that pseudohypericin can reduce the spread of HIV, at least in the test tube. At my urging, Jerry Cott, Ph.D., of NIMH may look at Hypericum hypericoides, yet another species. Hypericum also shows promise in fending off opportunistic infections, such as cytomegalovirus. Hypericum might be doubly useful in treating AIDS because of its antiviral and antidepressant properties, says a 1995 article in the Psychiatric Times. The Journal of the American Medical Association reports that half of all people with a medical illness also are depressed. Adding St. John's wort to the HIV/AIDS weaponry might boost patient morale and the immune system, possibly slowing the virus. _________________ JoAnn Guest mrsjo- DietaryTi- www.geocities.com/mrsjoguest/Genes AIM Barleygreen " Wisdom of the Past, Food of the Future " http://www.geocities.com/mrsjoguest/Diets.html Make your home page Quote Link to comment Share on other sites More sharing options...
