Ginger root (Zingiber officinale), used historically in traditional medicine to treat indigestion and nausea, may also help people with Type 2 diabetes, suggests a new study from Brazil. Researchers conducted a randomized, double-blind study of 103 people with Type 2 diabetes that were taking medications. Those taking 1.2 grams of ginger powder for 90 days experienced a significant drop in the level of fasting blood sugar, total cholesterol and LDL cholesterol compared to those taking a placebo.
