Crataegus: Hawthorn extract and heart failure
by Paul Bergner
Medical Herbalism 04-30-94 6(1): 12
A review article on Crataegus oxycantha (hawthorne), traditionally used as a heart tonic, reports the effect of a concentrated extract of the herb on all areas of the peripheral vessels. Four clinical placebo-controlled trials also showed improvement in “changes in stress tolerance” and “anaerobic threshold.” In one study, the hawthorn extract was found to be clinically equivalent, after fifty-six days of use, to captorpil, an allopathic ACE-inhibitor used in congestive heart failure and hypertension.
