Kudzu for Metabolic Syndrome
Republished with permission of Natural Standards Research Collaboration ©2009


Kudzu, an invasive vine common in the southeast United States, may have medical applications. A new animal study suggests that the weed may help treat a condition known as metabolic syndrome.

People with metabolic syndrome have three or more of following medical conditions: high blood pressure, high insulin levels, excess fat around the waist and high cholesterol. Metabolic syndrome increases the risk of diabetes, heart disease and stroke.

Traditionally, kudzu has been used to treat high blood pressure, and some research suggests a possible benefit for insulin resistance. However, clear evidence is lacking in these areas.

In the report, published in the Journal of Agricultural and Food Chemistry, researchers tested the effects of kudzu root extract in female rats with high blood pressure that were prone to strokes. The rats also had symptoms of metabolic syndrome, making them suitable for studying this condition. One group received a standard diet, while the other received supplementation with kudzu root extract for two months.

At the end of the study, rats in the kudzu group gained less weight and had significantly lower blood pressure, blood sugar levels, insulin levels and total cholesterol levels compared to the control rats. The authors concluded that kudzu "may provide a dietary supplement that significantly decreases the risk and severity of stroke and cardiovascular disease in at-risk individuals."

While these early findings are promising, human studies are needed to determine if kudzu is a safe and effective treatment for metabolic syndrome in people.
