Reports of a traditional Chinese medicine having beneficial effects for
people suffering from type 2 diabetes
now has some scientific evidence to back up the claims. A collaboration
between Chinese, Korean, and
Australian scientists at Sydney's Garvan Institute, has revealed that
the natural plant product berberine could be a valuable new treatment.
Berberine is found in the roots and bark of a number of plants
used for medicinal purposes including wound
healing and treatment of diarrhoea. It has also been documented in
Chinese literature as having a glucose lowering effect when
administered to people with diabetes; yet, until now, its mode of
action was unknown.
Garvan
scientist Dr Jiming Ye says: "Our studies in animal models of diabetes
show that berberine acts in part by activating an enzyme in the muscle
and liver that is involved in improving sensitivity of the tissue to
insulin – this in turn helps lower blood sugar levels. In addition, it
seems berberine can help reduce body weight".
