MONDAY, June 4 (HealthDay News) — The herb ginseng appeared to
significantly reduce cancer-related fatigue compared to an inactive
placebo, although it took several weeks for the herb’s effects to take
effect in the patients, a new study reports.
In the study, the researchers gave either a placebo or 2,000-milligram
capsules of ground ginseng root to 340 patients who were being treated for
cancer or had completed cancer treatment. Fatigue is extremely common
among cancer patients; most of those in the study suffered from breast
cancer.
The patients took capsules of pure American ginseng instead of some
over-the-counter ginseng products that can include ethanol. Ethanol may be
potentially dangerous to breast cancer patients, study researcher Debra
Barton of the Mayo Clinic Cancer Center said in a news release from the
clinic.
“After eight weeks, we saw a 20-point improvement in fatigue in cancer
patients, measured on a 100-point, standardized fatigue scale,” Barton
said.
Those who took the ginseng capsules didn’t report much improvement at
four weeks, but at eight weeks they reported they felt less “worn out,”
“fatigued,” “sluggish” or “tired,” compared to those who took the placebo,
the investigators found.
The study authors noted that ginseng didn’t seem to have any side
effects. They didn’t specify how much the ginseng treatments would
cost.
A previous Mayo Clinic study found that about one-quarter of patients
who’d had cancer and suffered from fatigue said they felt “moderately
better” or “much better” after taking 1,000-milligram or 2,000-milligram
ginseng tablets. By comparison, only 10 percent of those who took the
placebo reported those results.
Laura Murphy, a professor of physiology at Southern Illinois University
Carbondale who’s familiar with the research, said it’s a helpful addition
to existing knowledge. The cost of ginseng will be inexpensive compared to
prescription drugs that could be used to treat fatigue, she said.
Why might ginseng help fatigue? It’s not clear, said Murphy, who has
studied the herb. “Essentially, when healthy people ingest ginseng, there
are no notable effects,” she said. “However, when an ill person takes
ginseng, they tend to feel more normal.”
The study, funded by the U.S. National Cancer Institute and the Breast
Cancer Research Foundation, was scheduled to be released June 4 at the
annual meeting of the American Society of Clinical Oncology in
Chicago.
The data and conclusions of research presented at medical meetings
should be viewed as preliminary until published in a peer-reviewed
journal.
