• Angina. It is unclear if oral hawthorn is beneficial in patients with angina. Details: Preliminary clinical research in patients with angina taking chronic beta-adrenergic receptor blockers or ACE inhibitor therapy shows that taking a hawthorn (Crataegus pinnatifada) extract 100 mg orally three times daily for four weeks improves angina and electrocardiogram (ECG) findings and reduces nitroglycerin intake when compared with placebo (19242). Other preliminary clinical research in patients with unstable angina shows that taking hawthorn 10 grams and hu zang 15 grams orally daily for 4 weeks does not reduce the frequency of angina pectoris attacks when compared with control. However, taking hawthorn and hu zang improved some subjective symptom scores and quality of life scores (109610).
• Anxiety. Oral hawthorn has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A clinical study in adults with mild to moderate generalized anxiety shows that taking a specific product (Sympathyl, not available in the US) containing hawthorn, magnesium, and California poppy for 90 days modestly improves anxiety scores when compared with placebo (12583). Also, a clinical study in adults with adjustment disorder and anxious mood shows that hawthorn, in combination with black horehound, passion flower, valerian, kola nut, and guarana, modestly improves anxiety scores when compared with placebo (6250). It is unclear if these effects are due to hawthorn, other ingredients, or the combination. Another small clinical study in healthy adults shows that taking a combination of herbal extracts containing hawthorn, passionflower, ballota, and valerian root daily for 14 days reduces subjective anxiety and objective sympathetic and autonomic nervous system activation in response to a psychosocial stressor when compared with placebo (111222). It is unclear if these effects are due to hawthorn, other ingredients, or the combination.
• Arrhythmia. Although there has been interest in using oral hawthorn for arrhythmia, there is insufficient reliable information about the clinical effects of arrhythmia for this condition.
• Atherosclerosis. Although there has been interest in using oral hawthorn for atherosclerosis, there is insufficient reliable information about the clinical effects of arrhythmia for this condition.
• Cardiovascular disease (CVD). Although there has been interest in using oral hawthorn for CVD, there is insufficient reliable information about the clinical effects of arrhythmia for this condition.
• Cognitive function. Oral hawthorn has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In a preliminary clinical trial, a single dose of 25 drops of a combination product of D-camphor and hawthorn berry extract (Korodin) was superior to placebo for increasing cognitive performance in elderly female patients as measured by visuomotor speed and information processing capacity. The active treatment group showed an improvement in attentional and mental performance (19240,91504).
• Congestive heart failure (CHF). The evidence on the effects of oral hawthorn in patients with CHF is conflicting. Although some older research suggests it may be beneficial, more recent, larger studies suggest it may actually increase the risk for complications. Details: There is contradictory evidence about the effects of hawthorn extract in heart failure patients. Several clinical studies show that taking specific hawthorn leaf and flower extracts (LI 132, Faros 300, Lichtwer Pharma; WS 1442, Crataegutt forte, Dr. Willmar Schwabe Pharmaceuticals; or HeartCare, Nature's Way) 240-600 mg daily improves ejection fraction and exercise tolerance, reduces subjective symptoms, and decreases the risk of death in patients with New York Heart Association (NYHA) stage II heart failure. In these studies, the maximum effect was usually seen after 6-12 weeks of treatment (8279,8280,11449,19221,19223,19225,19226,19227,19228). Another clinical trial shows that hawthorn extract (WS 1442, Crataegutt forte, Dr. Willmar Schwabe Pharmaceuticals or HeartCare, Nature's Way) 1800 mg daily, combined with diuretic therapy, improves exercise tolerance and reduces subjective symptoms in NYHA stage III heart failure. In this study, maximum effect was usually seen after 16 weeks of treatment (8281). In another trial, patients with NYHA II heart failure taking either hawthorn (LI 132, Faros) 300 mg three times daily or captopril 12.5 mg three times daily experienced similar improvements in cardiac performance and symptoms (19230). However, other clinical research suggests no benefit and possible harm with hawthorn. A large-scale clinical trial (SPICE) in patients with NYHA stage II or III heart failure shows that taking specific hawthorn extracts (WS 1442, Crataegutt forte, Dr. Willmar Schwabe Pharmaceuticals; HeartCare, Nature's Way) 900 mg daily for 24 months, in combination with conventional treatment, does not decrease hospitalization due to progressive heart failure, non-fatal myocardial infarction, or cardiac death (17203). Another clinical trial in patients with NYHA stage II or III heart failure shows that taking these same specific hawthorn extracts at the same dose for up to 6 months does not slow the progression of heart failure when compared with placebo (19222). In a retrospective analysis of this study, it was shown that heart failure progression was significantly increased in patients taking hawthorn when compared with placebo. The rate of death was also increased by 1.7% over placebo, and heart failure-related hospitalizations increased by 8% over placebo in patients treated with hawthorn (16824).
• Hyperlipidemia. Although there has been interest in using oral hawthorn for hyperlipidemia, there is insufficient reliable information about the clinical effects of arrhythmia for this condition.
• Hypertension. It is unclear if oral hawthorn is beneficial for lowering blood pressure. Details: One preliminary clinical trial showed that taking hawthorn standardized extract 1,000-2,500 mg daily for three days does not significantly reduce blood pressure in hypertensive or prehypertensive patients when compared with placebo (19244). However, another study in patients with diabetes and hypertension shows that taking a specific hawthorn extract (LI 132) 1,200mg daily for 16 weeks significantly decreased diastolic, but not systolic, blood pressure when compared with placebo (19245).
• Orthostatic hypotension. Oral hawthorn has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in older adults with orthostatic hypotension shows that taking a specific combination product containing hawthorn and camphor (Korodin Herz-Kreislauf-Tropfen) 25 drops orally three times daily for 7 days attenuates the blood pressure reduction upon standing when compared with placebo. Signs and symptoms of orthostatic hypotension such as dizziness, blurry vision, and falls also seem to be reduced when compared with baseline (39614,39617). A meta-analysis of 4 studies shows that giving single doses of 20-25 drops of the same combination product increases systolic and diastolic blood pressure when compared with placebo (103620). However, the studies have methodologic problems and, while 2 were conducted in females with orthostatic hypotension, the others involved health young adults or normotensive elderly subjects. The effect of hawthorn alone for treatment of orthostatic hypotension has not been determined. The combination product used in these studies is not available in the US. More evidence is needed to rate hawthorn for these uses.

• Intermittent claudication. Oral use of policosanol can increase walking distance in patients with intermittent claudication. Details: Multiple, small, randomized controlled trials show that taking policosanol 10 mg orally once to twice daily for up to 2 years moderately improves walking distance when compared with placebo, lovastatin, or aspirin, and has similar effects to ticlopidine, in patients with intermittent claudication (2931,65359,65372,65378,69114).

• Angioplasty. It is unclear if oral policosanol is beneficial for patients after angioplasty. Details: Preliminary clinical research has evaluated the addition of policosanol to dual antiplatelet therapy in Chinese patients with high on-treatment platelet reactivity (HPR) who underwent percutaneous coronary intervention with a drug-eluting stent for an acute coronary syndrome. The addition of policosanol 40 mg orally daily with clopidogrel 75 mg daily and aspirin 300 mg daily for 30 days does not further reduce HPR when compared with taking clopidogrel and aspirin alone (100684).
• Coronary heart disease (CHD). It is unclear if oral policosanol is beneficial for patients with CHD. Details: One small clinical study in adults with CHD shows that taking policosanol 5 mg twice daily, alone or in combination with aspirin 125 mg for 20 months, can reduce cardiac events and improve maximum oxygen uptake during a treadmill exercise electrocardiogram (ECG) when compared with pretreatment (2941). Policosanol has also been evaluated as part of combination products for CHD. Clinical research in statin-intolerant patients with CHD treated with a percutaneous intervention (PCI) shows that taking a specific combination product (Armolipid Plus, Rottapharm S.p.A.) containing policosanol, berberine, red yeast rice, folic acid, coenzyme Q10, and astaxanthin daily for 3 months reduces total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides, and increases high-density lipoprotein (HDL) cholesterol, to a greater extent than ezetimibe 10 mg daily. Combining this specific product with ezetimibe produces additional improvements after 1 year of treatment when compared with either agent alone (97232). Other clinical research in patients with CHD treated with PCI shows that taking the same product in combination with a low-dose statin for 3 months reduces total cholesterol and LDL cholesterol and increases HDL cholesterol when compared with low-dose statin treatment alone (97233). It is unclear if the benefits of this combination product are due to policosanol, other ingredients, or the combination.
• Familial hypercholesterolemia. It is unclear if oral policosanol is beneficial for patients with familial hypercholesterolemia. Details: Preliminary clinical research shows that taking a specific form of policosanol (Lesstanol Octa-60, Garuda International) 20 mg orally daily for 12 weeks does not significantly decrease total or low-density lipoprotein (LDL) cholesterol in patients with familial hypercholesterolemia (14404).
• Hypercholesterolemia. It is unclear if oral policosanol is beneficial for patients with hypercholesterolemia. Details: Current clinical research on the use of policosanol for hyperchloremia is conflicting. The reasons for these discrepant findings are unclear but may be explained by differences in doses, treatment durations, patient populations, and specific policosanol products studied. Clinical research in subjects with hypercholesterolemia, largely conducted by researchers in Cuba, shows that taking policosanol orally 5-20 mg daily for 8-24 weeks lowers total cholesterol by 9% to 29% and low-density lipoprotein (LDL) cholesterol by 11% to 42% and increases high-density lipoprotein (HDL) cholesterol by 7% to 34% when compared with placebo or other controls (2927,2928,2929,2930,2943,2944,14298,14411,65348,65354)(65355,65356,65361,65363,65365,65369,65375,65380,65383,69104)(69105,69106,65362,65351,100178). When compared to conventional drugs, some research also shows that policosanol 10 mg daily lowers total and LDL cholesterol by a similar amount as fluvastatin 20 mg daily and simvastatin 10 mg daily (8147,12190). Atorvastatin 10 mg daily appears to be more effective than policosanol 10 mg daily for lowering total and LDL cholesterol (14411). However, the majority of research conducted outside of Cuba has been contradictory. Research in subjects with hypercholesterolemia, conducted by German, Canadian, Croatia, South African, Netherlands, U.S., and Italian researchers, shows that taking policosanol 10-80 mg daily for 4-12 weeks does not significantly decrease total or LDL cholesterol when compared with placebo (14336,15062,69111,69119,69107,69109,69110,12166,14404). These studies included policosanol derived from Cuban sugar cane, U.S. sugar cane, wheat germ, and red yeast rice and specific policosanol products (Lesstanol Octa-60, Garuda International; Cholesstor, Pharmed Group) (69107,69109,69110,12166,14404). Policosanol has also been studied in combination with other ingredients. Taking a product containing policosanol 10 mg, berberine 500 mg, and red yeast rice 200 mg daily for up to 12 months seems to reduce total cholesterol and LDL cholesterol levels in hypercholesterolemic patients when compared with placebo or ezetimibe 10 mg (34262,34283,34301). Taking a specific combination product (Armolipid Plus, Rottapharm S.p.A.) containing policosanol, berberine, red yeast rice, folic acid, coenzyme Q10, and astaxanthin daily for 8 weeks appears to reduce total cholesterol by 13% and LDL cholesterol by 21%, as well as increasing HDL cholesterol by 5% when compared with baseline in patients with metabolic syndrome and dyslipidemia (89438). A meta-analysis also shows that taking this combination product for up to 1 year reduces total cholesterol by 10%, LDL cholesterol by 14%, and triglycerides by 7%, and increases HDL cholesterol by 4%, when compared with baseline in patients with hypercholesterolemia (92142). It is unclear if the benefits of this combination product are due to policosanol, red yeast rice (which contains monacolin K, a chemical similar to lovastatin), other ingredients, or the combination.
• Hypertension. It is unclear if oral policosanol is beneficial for patients with hypertension. Details: Clinical research in adults with prehypertension shows that taking policosanol 20 mg orally daily for 12 weeks reduces both systolic and diastolic blood pressure by about 7%, compared to non-significant changes with placebo. A lower dose of policosanol 10 mg daily did not improve blood pressure when compared with placebo (100177).
• Metabolic syndrome. Oral policosanol has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a specific combination product (Armolipid Plus, Rottapharm S.p.A.) containing policosanol, berberine, red yeast rice, folic acid, coenzyme Q10, and astaxanthin daily for 18 weeks improves systolic blood pressure, left ventricular mass, and flow-mediated dilation in patients with metabolic syndrome when compared with control (34289). It is unclear if these effects are due to policosanol, other ingredients, or the combination. More evidence is needed to rate policosanol for these uses.

POSSIBLY SAFE ...when used orally and appropriately, short-term. Hawthorn preparations in doses of up to 1800 mg daily seem to be safe when used for up to 16 weeks. Although hawthorn might be safe for long-term use, current studies have not evaluated safety past 16 weeks (8279,8280,8281,10144,17203,104689). There is insufficient reliable information available about the safety of hawthorn when used topically.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.  Details In vitro and animal research shows that hawthorn can inhibit platelet aggregation (95528,95529,95530,95531). However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract (95527). However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans (54664).

BETA-BLOCKERS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.  Details Some evidence shows that hawthorn might lower blood pressure and heart rate (12595,19245).

CALCIUM CHANNEL BLOCKERS Interaction Rating = Moderate Be cautious with this combination.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = B Theoretically, taking policosanol with other antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.  Details Some clinical research shows that taking policosanol 10-50 mg daily for 7-15 days can inhibit platelet aggregation in healthy patients (2936,2937,2938,103832). Although, one clinical trial shows that taking policosanol 10 mg twice daily for 2 weeks prior to warfarin dosing does not affect warfarin pharmacokinetics or warfarin response (20083). Furthermore, a study in patients undergoing percutaneous coronary intervention with a drug-eluting stent found that taking policosanol 40 mg plus clopidogrel and aspirin daily for 30 days modestly reduced the risk for minor bleeding events when compared with taking clopidogrel and aspirin alone (100684). Until more is known, use with caution.

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, policosanol might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.  Details Clinical research shows that policosanol can lower blood glucose levels (100178).

BETA-BLOCKERS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = A Concomitant use of policosanol with beta-blockers can cause additive blood pressure-lowering effects.  Details Clinical research shows that policosanol 5 mg daily can have additive blood pressure-lowering effects in patients with hypertension who are taking beta-blockers (65383). Also, animal research shows that policosanol can increase the blood-pressure lowering effects of propranolol (23775).

NITROPRUSSIDE (Nitropress) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of policosanol with nitroprusside might cause additive blood pressure-lowering effects.  Details Animal research shows that taking policosanol along with nitroprusside can increase the blood pressure-lowering effects of nitroprusside (65374).

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = B Theoretically, taking policosanol with warfarin might increase the risk of bruising and bleeding.  Details Some clinical research shows that taking policosanol 10-50 mg daily for 7-15 days can inhibit platelet aggregation in healthy patients (2936,2937,2938). However, one clinical trial shows that taking policosanol 10 mg twice daily for 2 weeks prior to warfarin dosing does not affect warfarin pharmacokinetics or warfarin response (20083).

General ...Orally, hawthorn seems to be well tolerated when used appropriately. Topically, no adverse effects have been reported, although a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Multiorgan hypersensitivity reactions resulting in acute renal failure have been reported rarely.

Cardiovascular ...Orally, tachycardia (with facial pains) of uncertain relationship to hawthorn was reported in a multicenter clinical trial (54640). Palpitations (19244) were reported in three patients in a large surveillance trial of 3,664 patients with cardiac failure (54692) and in 11 patients with congestive heart failure (CHF) in a literature review of 5,577 patients (19247). Circulation failure has been reported in two patients with CHF in a literature review of 5,577 patients (19247). Incidences of hospitalization, hospitalization due to CHF, worsening of CHF, angina, and atrial fibrillation have also been reported with the use of hawthorn extract WS 1442 (Crataegutt forte), although it is unclear if these events are related to hawthorn supplementation or existing CHF (19222). In clinical trials, chest pain (8281), short-term increases in blood pressure (19240), and other non-specific heart problems (17203) have also been reported following the use of various hawthorn preparations (e.g. WS 1442, Korodin).

Dermatologic ...Orally, erythematous rash has been reported in patients with CHF in a literature review of 5,577 patients (19247). Non-specific rashes and itching (19222,19243) as well as toxiderma from the fruits of hawthorn (54670) have also been reported.

Gastrointestinal ...Orally, rare abdominal discomfort of uncertain relationship to hawthorn has been reported in a large clinical trial, surveillance study, and a literature review (19247,54640,54692).

General ...Orally, policosanol is usually well-tolerated.
Most Common Adverse Effects:
Orally: Dysuria, headache, insomnia, polyphagia, pruritis, skin rash, somnolence, upset stomach, vertigo, weight loss.

Dermatologic ...Orally, policosanol can cause pruritus or skin rash, but these events appear to be uncommon (65369,95374,100178). In one clinical trial that included over 50 patients, one case of policosanol-associated skin rash was reported (65369). In another study, 1 out of 40 patients treated with policosanol 10 mg daily reported pruritus (95374).

Gastrointestinal ...Orally, policosanol can cause upset stomach or polyphagia (2937).

Genitourinary ...Orally, policosanol can cause dysuria (2937).

Hematologic ...A case gum bleeding has been reported in a patient taking policosanol 20 mg and aspirin 100 mg daily for 7 days (2937).

Neurologic/CNS ...Orally, policosanol may cause headache, mild vertigo, somnolence, irritability, or insomnia but these events are uncommon. In one clinical study, 1 out of 44 subjects receiving policosanol 20 mg daily 12 weeks experienced mild vertigo and 2 out of 44 experienced mild headache (14404). In another study, 2 out of 70 patients taking policosanol 10 mg daily for 8 weeks experienced headache (69119). In another study, 1 out of 40 patients taking policosanol 10 mg daily reported insomnia (95374).

Other ...Orally, policosanol has been associated with weight loss. However, evidence from a post-market surveillance study of patients taking policosanol 5-15 mg daily shows that this adverse event is uncommon (95375).
