SYDNEY (UPI) -- There is positive evidence Chinese herbal medicines may prevent diabetes in those at high risk, an Australian review says, but more study is needed. The Cochrane review of 16 studies finds combining herbal medicines with lifestyle changes is twice as effective as lifestyle changes alone at normalizing patients' blood sugar levels. However, the researchers concluded there was not enough hard scientific evidence to recommend their use. "Our results suggest that some Chinese herbal medicines can help to prevent diabetes, but we really need more research before we can confidently say that these treatments work," lead researcher Suzanne Grant of the Centre for Complementary Medicine Research at the University of Western Sydney in Australia, says in a statement. "The real value of the study is as guidance for further trials. We need to see more trials that make comparisons with placebos and other types of drugs, and better reporting on the outcomes of these trials." The clinical trials included 1,391 people who received 15 different herbal formulations. Those given the herbal formulations were less likely to develop full blown diabetes during the study period. Trials lasted from one month to two years and no adverse effects were reported. The finding is published in the Cochrane Library.
