Over the past few days, a group of Cochrane Researches have released data from a study that tested hawthorn extract. A goal of the study was to determine if hawthorne extract had any positive affect on the body of patients going through heart failure. They did this by providing a total of 855 patients; with a placebo given for some, and hawthorn extract to others, it was going to be possible to see what groups had the great positive change(s).

The study concluded hawthorn extract had “significant” positive impacts upon the people that took it over the patients that took the placebo. The patients that took the hawthorn extract saw:

• increased maximal workload
• increased tolerance for exercise
• reduced the oxygen consumption of the heart
• reduced shortness of breath and fatigue

Unfortunately, a few people reported mild nausea dizziness, as well as heart and stomach complaints.
