Ginseng, with two other ingredients that together form a traditional Japanese herbal medicine, promotes gastrointestinal health and regular bowel movements, a recent study showed. The findings, published in the journal Neurogastroenterology and Motility, revealed that Dai-Kenchu-to, a mixture of ginseng, ginger and zanthoxylum fruit, helped relieve constipation in children and in patients with post-operative ileus. The latter is a disruption of normal bowel movements after an operation.
“Japanese herbal medicines have been used in East Asia for thousands of years,” said lead researcher Hidekazu Suzuki, an associate professor at the Keio University School of Medicine. “Our review of the world medical literature reveals that herbal medicines serve a valuable role in the management of patients with functional gastrointestinal disorders.” The research is significant because many pharmaceutical medicines used to treat so-called gastrointestinal “motility disorders” have been found to be ineffective or fraught with side effects, with some even having been withdrawn from the market. The scientists reviewed data from studies that examined not only Dai-Kenchu-to but a number of other Japanese herbal treatments, including Rikkunshi-to and hangeshashin-to. Rikkunshi-to, a preparation of eight herbs, reduced discomfort from indigestion. Hangeshashin-to was effective in alleviating the severity and frequency of diarrhea caused by anti-cancer drugs. Herbal medicines are utilized much more widely in Japan than in the West. In Japan, companies manufacture these formulations according to standardized measures of the ingredients’ quality and quantity. Suzuki and his colleagues said the health benefits of standardized concoctions of herbal medicines need to be more rigorously examined, so that particularly the Western world can appreciate and reap any potential benefits.
“There is a mandate to provide accurate data regarding the effectiveness of non-traditional therapy, not only to our patients but also to health-care providers who face the dilemma of recommending or opposing management strategies that incorporate herbal medicine,” said Suzuki.

Health Wrap:Snoring, Fetuses and Pain
A new study finds that habitual snoring in women is strongly tied to body mass index—a marker of fatness-- and age. Overall, 7.6 percent of women snore. The frequency of snoring reaches its peak in women ages 50 to 59. Frequent snoring was found to increase with alcohol dependence, smoking and physical inactivity. --

Talking on your cell phone before going to bed could interfere with getting a good night's sleep, a recent study suggests. Carried out by Sweden's Karolinska Institute and Wayne State University in the US, the study suggests radiation from the handset can cause insomnia, headaches, and confusion. Scientists studied 35 men and 36 women between the ages of 18 and 45 who were exposed to radiation equivalent to that received when using a mobile phone. Others were placed in the same conditions, but given only false exposure. Those exposed to radiation took longer to enter the first of the deeper stages of sleep, and spent less time in the deepest one.

Recent studies are demonstrating that Computerized tomographic (CT) colonography, also known as virtual colonoscopy, is as accurate as standard colonoscopy in its ability to accurately detect cancer and precancerous polyps. Recent studies are demonstrating that Computerized tomographic (CT) colonography, also known as virtual colonoscopy, is as accurate as standard colonoscopy in its ability to accurately detect cancer and precancerous polyps. As a result the virtual colonoscopy could serve as an initial screening exam for colorectal cancer. It is hoped that non-invasive virtual colonoscopy will encourage more people over 50 to do this life-saving screening. The results of this study were published in the Sept. 18, 2008, issue of the New England Journal of Medicine.
