7- Yarrow Regulate Blood Pressure
Studies have shown that yarrow is an effective treatment for hypertension, or high blood pressure. It works by relaxing the smooth muscles of the walls of your arteries and veins which helps reduce your overall blood pressure. It also helps increase circulation throughout your body which further helps lower your BP levels. Additionally, research has shown that yarrow increases production of nitric oxide which relaxes constricted arteries and improves overall cardiovascular health. (4)
