Natural Standard Bottom Line Monograph, Copyright © 2007 (www.naturalstandard.com).
Commercial distribution prohibited. This monograph is intended for informational purposes only,
and should not be interpreted as specific medical advice. You should consult with a qualified
healthcare provider before making decisions about therapies and/or health conditions.
While some complementary and alternative techniques have been studied scientifically, high-quality data regarding
safety, effectiveness, and mechanism of action are limited or controversial for most therapies. Whenever possible, it
is recommended that practitioners be licensed by a recognized professional organization that adheres to clearly
published standards. In addition, before starting a new technique or engaging a practitioner, it is recommended that
patients speak with their primary healthcare provider(s). Potential benefits, risks (including financial costs), and
alternatives should be carefully considered. The below monograph is designed to provide historical background and
an overview of clinically-oriented research, and neither advocates for or against the use of a particular therapy.

Hawthorn, a flowering shrub of the rose family, has an extensive history of use in
cardiovascular disease, dating back to the 1st Century. Modern day animal and in vitro
studies suggest that flavonoids and other pharmacologically active compounds found in
hawthorn may synergistically improve performance of the damaged myocardium, and
further, may prevent or reduce symptoms of coronary artery disease.
Numerous well-conducted human clinical trials have demonstrated safety and efficacy of
hawthorn leaf and flower in New York Heart Association (NYHA) Class I-II heart failure
(characterized by slight or no limitation of physical activity). An international, multi-center
randomized controlled trial is currently underway to investigate long-term benefits.
Hawthorn is widely used in Europe for treating New York Heart Association (NYHA) Class I-II
heart failure, with standardization of its leaves and flowers. Overall, hawthorn appears to be
safe and well tolerated, and in accordance with its indication, best used under the
supervision of a medical professional.
The therapeutic equivalence of hawthorn extracts to drugs considered standard-of-care for
heart failure (such as angiotensin converting enzyme inhibitors, diuretics, or beta-adrenergic
receptor blockers) remains to be established, as does the effect of concomitant use of
hawthorn with these drugs. Nonetheless, hawthorn is a potentially beneficial therapy for
patients who cannot/will not take prescription drugs, and may offer additive benefits to
prescription drug therapy.

patients who cannot/will not take prescription drugs, and may offer additive benefits to

Uses
These uses have been tested in humans or animals. Safety and effectiveness have not always been
proven. Some of these conditions are potentially serious, and should be evaluated by a qualified
healthcare provider.
Grade*
Congestive heart failure
Extracts of the leaves and flowers of hawthorn have been reported as efficacious in
the treatment of mild-to-moderate congestive heart failure (CHF), improving
exercise capacity, and alleviating symptoms of cardiac insufficiency. However, the
therapeutic equivalence of hawthorn extracts to drugs considered standard-of-care
for heart failure (such as angiotensin converting enzyme inhibitors, diuretics, or
beta-adrenergic receptor blockers) remains to be established, as does the effect of
concomitant use of hawthorn with these drugs. Nonetheless, hawthorn is a
potentially beneficial treatment for patients who cannot/will not take prescription
drugs, and may offer additive benefits to established therapies. Further study of
these issues is warranted.
A
Coronary artery disease (angina)
Hawthorn has not been tested in the setting of concomitant drugs such as betablockers or ACE-inhibitors, which are often considered to be standard-of-care. At
this time, there is insufficient evidence to recommend for or against hawthorn for
coronary artery disease or angina.
C
Functional cardiovascular disorders
Two randomized trials have found efficacy of herbal combinations containing
hawthorn in the treatment of functional cardiovascular symptoms. However, due to a
lack of controlled information on hawthorn monotherapy, there is insufficient
evidence to recommend for or against hawthorn for functional cardiovascular
disorders.
C
*Key to grades: A: Strong scientific evidence for this use; B: Good scientific evidence for this use; C:
Unclear scientific evidence for this use; D: Fair scientific evidence against this use (it may not work); F:
Strong scientific evidence against this use (it likely does not work).
The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly
tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are
potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses
that are not listed below.

Not recommended due to lack of sufficient data.
Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs,
or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or
traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs,
herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.
Interactions with Drugs:
Additive inotropic effects when used with cardiac glycoside drugs such as digoxin have been
noted in animals without added toxicity. In humans, hawthorn has been used with the
intention of decreasing digoxin doses, although data on safe and efficacious dosing in this
setting is still limited.
Hawthorn may have additive activity with medications that lower blood pressure. Hawthorn
may add to the activity of drugs that dilate blood vessels, and may decrease the effects of
vasoconstrictors such as phenylephrine (Neo-Synephrine®), ephedrine or norepinephrine.
Hawthorn may also have additive activity with medications that reduce cholesterol levels.
Interactions with Herbs and Dietary Supplements:
Hawthorn may add to the effects on the heart of agents containing cardiac glycosides.
Hawthorn may add to the effects of agents that lower blood pressure.
Hawthorn may have additive activity with agents that reduce cholesterol levels such as
garlic, niacin, or fish oil (omega-3 fatty acids).
