Ginseng can reduce cancer-related tiredness
Ginseng
may help long-standing cancer patients to ward off the tiredness caused by the
condition, found researchers from the Mayo Clinic Cancer Centre in US. The regular
intake of high doses of the ginseng over two months significantly reduced
cancer-related tiredness in patients in comparison to any other medication.
Ginseng
has long been used as a natural energy booster in traditional Chinese medicine.
Fatigue in cancer patients has been associated with the rise in inflammatory
cytokines in the immune system plus inadequate regulation levels of the
stress-hormone cortical.
Until
this study, the beneficial effects of ginseng had not been tested extensively
against the debilitating fatigue that occurs in more than ninety percent of
cancer patients. For their study
researchers examined three hundred and forty cancer patients who had completed
their treatment at one of forty community medical centers in US.
The
study participants were given two thousand milligram of ginseng in the form of
capsule containing pure, ground American ginseng root or placebo, daily. After
eight weeks, ginseng offered cancer patients significant improvement in general
exhaustion such as feeling of being worn
out, sluggish or tired compared to
patients taking placebo.
The
active ingredient on ginseng called as ginsenosides has already been shown to reduce
cytokines related to inflammation and help regulate cortisol levels in animal
studies. Lead researcher Doctor Debra Barton, stated off-the-shelf ginseng is
sometimes processed using ethanol, which can give it oestrogen-like properties
that may be harmful to breast cancer patients.
At
fourth week, the pure ginseng provided only a slight improvement in fatigue
symptoms. But, after eight weeks, they saw a twenty-point improvement in
fatigue in cancer patients, measured on a one hundred-point, standardized
fatigue scale. Besides, the herb had no apparent side effects. The next study
will look closely examine effects of ginseng on the specific biomarkers for
fatigue, stated Dr Barton.
