Scientists have cast doubts on the efficacy of Chinese herbal medicines in preventing type 2 diabetes in high-risk patients.

In China, Korea and Japan herbal pills, teas and powders have been used for a long time to treat pre-diabetes and diabetes.

But the researchers say that there is lack of hard scientific evidence to confidently recommend their use.

Those given the herbal formulations were less likely to develop full blown diabetes during the study period. Trials included in the review lasted from one month to two years. No adverse effects were reported in any of the trials.

"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," said Grant.

"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," she added. (ANI)
