Tropical Leaf Extracts Linked to Improving Pre-Diabetes

New research published in the Nutrition Journal concludes that extracts from the two tropical plants may

provide solutions to reversing pre-diabetes. Leaf extracts from E. guineensis (a tropical plant producing edible oil), and F. deltoidea (a traditional tea) contain phenolic compounds that have hypoglycemic effects in vitro and in vivo.

The research for this article was based on an eight week study. More research and a larger test group are needed to determine maximum effective dosages. Prelimary conclusions are that the leaf extracts had positive effects on glucose and lipid levels and are safe for use in humans.

This study is important because in 2010, the World Health Organization reported that 347 million people worldwide had diabetes. This number is expected to increase to 439 million adults by 2030.
