Here is a visit to the six acre farm and home, of James Duke, Ph.D., one of the world's leading authorities on healing herbs, the man who brought us the classic The Green Pharmacy, that is now an indispensable resource for some of the world's foremost herbalists.
Tireless though retired, Duke, at 75, is now actively engaged in what may be his most challenging yet simplest experiment, an ongoing series of trials using only one clinical subject: his own aging body.
Though he'd be the last person to suggest he's got the definitive answer for himself or particularly for others, seeing the choices he's making can teach everyone about which herbs to consider for long-term health.
For most of his career Duke worked for the U.S. Department of Agriculture as chief of its Medicinal Plant Resources Laboratory. He and his team collected plants from around the globe for their potential cancer-fighting compounds, which were analyzed by researchers at the National Cancer Institute. Before the project ended, the NCI had analyzed 10 percent of the plants on earth, most of them collected by Duke and his colleagues.
His interest was broader than cancer, though. From 1965 through 1968 Duke took a leave from the USDA post and packed Mrs. Duke and their children--at the time, an infant and a toddler--off to Panama. "It was there that I got into natural remedies used by Indians," says Duke. "In Panama I became an ethno-botanist." Oddly enough, Duke's sponsor in Panama was the Atomic Energy Commission, which hired him to do a survey of indigenous plants. It may have been a devil's bargain--"Hated my sponsor, loved the job"--but it was a high point in Duke's career. "I collected over 18,000 specimens, 50 of which were undescribed previously."
Bilberry
"A master antioxidant"
Like its close relative, blueberry, bilberry contains potent antioxidants that help prevent many age-related ailments. This herb is particularly good for preserving vision and preventing degenerative eye diseases such as macular degeneration and cataracts.
Celery Seed
"Herbal Celebrex"
Celery seed has helped keep Duke's gout in check and can help ease the pain and inflammation of arthritis. While American research supporting this purpose is limited, studies in India and Australia have been promising. The herb contains more than a dozen anti-inflammatory ingredients, including a COX-2-inhibiting compound that works by a similar mechanism as the drug Celebrex.
Echinacea
"One of the best herbal immune-system enhancers"
Duke swears by the immune-enhancing properties of the popular cone-flowered herb, despite a few recent well-publicized studies that have questioned its benefits. Dozens of chemical studies, and other clinical studies, have shown that echinacea can help boost the immune system as well as reduce the severity and length of symptoms of colds and flus.
Garlic
"Herbal duct tape"
If Duke were stranded on a desert island with a single herb, garlic would be it. Regular use can help prevent heart disease by lowering blood pressure and total cholesterol, raising good (HDL) cholesterol, and inhibiting the formation of blood clots that trigger heart attack. It's also an antimicrobial, meaning that it helps the body fight viruses, bacteria, and fungi.
Ginkgo
"A certifiable fountain of youth"
Ginkgo's many benefits appear to stem from its ability to improve blood flow, particularly in the brain and extremities. Research has pointed to the herb's ability to slow Alzheimer's when taken in the disease's early stages. Gingko also may help prevent heart attack, macular degeneration, tinnitus, and certain types of impotence.
Hawthorn
"The best herbal heart tonic around"
Hawthorn has a long history as a slow-acting but effective tonic that can strengthen the heart and boost the health of the circulatory system. A number of clinical studies have shown it to be effective in gently normalizing heart function in congestive heart failure; it's also used to help treat heart disease. The active compounds are found mainly in hawthorn's berries and flowers.
Milk Thistle
"Long live the liver lover"
Milk thistle is an herbal superstar the world over, with both popular and scientific support for its use as a liver protector. It can safeguard this vital organ against cirrhosis and hepatitis, and recent research suggests that the herb may help prevent cancer, type 2 diabetes, and syndrome X. And to combat lifestyle and environmental "insults"--like alcohol, pollution, and medications--it's "one of the best detoxifiers around," says Duke.
St. John's Wort
"The herb of choice for mild to moderate depression"
Keeping your spirits up is one of the keys to longevity; chronic depression can suppress the immune system, upping the risk for a number of chronic conditions. St. John's wort has been used as a mood booster for centuries, and modern science has shown it to be an effective natural alternative for mild to moderate depression. (Severe depression should be treated medically, with the help of health professionals.)
Saw Palmetto
"I'm betting my prostate gland on it"
Thus far, Duke's bet has paid off. One of the most thoroughly studied herbs, saw palmetto has been proven to
be as effective as a leading prescription medication for
benign enlarged prostate. In Europe, it's been the treatment of choice for years. Duke stresses that it's important to see your doctor for a diagnosis before taking saw palmetto.
Turmeric
"A remarkable anti-inflammatory"
A mainstay in Ayurvedic medicine, turmeric has long been used to ease inflammatory conditions such as arthritis, bursitis, and tendinitis. Clinical studies have confirmed that it appears to be as effective as NSAIDS, and safer, as well as having cholesterol-lowering, liver-supporting, and anticancer benefits. (For more on its healing potential, see "Turmeric" on page 42.) Duke sprinkles it on chicken and vegetables to make curries, but supplements are also available.
