Significant scientific evidence confirms Hawthorn’s traditional use. It has been the subject of hundreds of research studies, including nine double-blind, placebo-controlled human clinical trials.
The results of this research show that Hawthorn strengthens the heart muscle, increases exercise tolerance, and supports a normal heart rhythm.*
While Hawthorn leaf contains high levels of flavonoids, the berry is rich in oligomeric procyanidins. The current thinking is that Hawthorn’s biological activity is not due to one group of constituents, but the interaction of various compounds.
Experimental and human research indicates these compounds work together to reinforce the heart’s pumping capacity, support coronary blood flow, and provide antioxidant protection to the heart.*
