Overview

Hawthorn is one of the oldest known medicinal plants. The berries, leaves, and flowers contain flavonoids, OPCs, and triterpenic acids that support cardiovascular function. In Germany, hawthorn extract is an approved treatment for early-stage heart failure. Beyond heart failure, hawthorn has been studied for blood pressure regulation, cholesterol management, and anxiety. Its mechanism involves ACE inhibition, antioxidant protection, and positive inotropic effects on the heart muscle.
