Hawthorn (Crategus oxycantha), a fruit from the temperate regions, has now emerged the best herbal treatment for heart related ailments. In numerous studies, it has been found not only to reduce heart failure symptoms but also to increase exercise capacity of individuals. Hawthorn also seems to bring down blood pressure, angina, lower bad cholesterol and triglyceride content in blood, and accumulation of fat in liver and blood vessels. These effects seem to be there due to the presence of a component in proanthocyanidin in this fruit.
