Red Raspberry (Raspberry ketone): a widely eaten berry that has also been used for medicinal purposes throughout history. It is not know why red raspberry may have health benefits, but it may be due to antioxidant or muscle relaxant properties. Red raspberry has been used to relieve symptoms of gastrointestinal conditions, heart problems, menstrual discomfort, easing labor and delivery, and morning sickness of pregnancy. More recently, "raspberry ketone" has been promoted as a weight loss aid, promoting weight loss by increasing norepinephrine release in the body and speeding up metabolism, including increasing heart rate. However, scientific proof is lacking, and people with certain medical conditions or those taking certain medications may be negatively affected by taking raspberry supplements.
