"Dietitian warns against 4 supplements for high blood pressure"
People with high blood pressure should avoid taking certain supplements, including licorice root, potassium supplements, ginseng, and guarana, as they can increase blood pressure or interfere with blood pressure medication. Instead, they should focus on making dietary changes, such as following the DASH diet, which includes eating mostly whole foods, reducing sodium intake, and increasing intake of potassium-rich foods like fruits, vegetables, and low-fat dairy products.
