Hawthorn has been used for centuries as a treatment for heart problems. A new Cochrane review shows that a few months of treatment with the Hawthorn extract, along with the patient's conventional treatments for chronic heart failure, is beneficial, and that the side effects are generally tolerable.
Researchers found 14 double-blind, placebo controlled randomised clinical trials (RCTs) including about a thousand patients. Those trials that could be included in a meta-analysis showed improvements in heart failure symptoms and in the function of the heart.
