• 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).
• Obesity. Although there has been interest in using oral hawthorn for obesity, there is insufficient reliable information about the clinical effects of hawthorn for this condition.
• 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.

• Alcohol use disorder. Oral kudzu seems to be beneficial for reducing alcohol consumption in heavy drinkers; however, it may not be beneficial in those with chronic alcohol use disorder. Details: Some research shows that heavy drinkers who take a specific kudzu root extract (Alkontrol-Herbal; NPI-031; Natural Pharmacia International, Inc.) 0.5-1 grams three times daily for 1-4 weeks consume less beer when given an opportunity to drink and may have more abstinent days (13085,92257). Other research shows that binge drinkers who take kudzu extract 2 grams as a single dose 2.5 hours prior to a 90-minute binge drinking episode consume 37% fewer beers than those taking placebo (92258). However, kudzu does not seem to decrease the craving for alcohol (10386,13085,57948,92257). Kudzu extract also does not seem to improve sobriety in people with chronic alcohol use disorder (10386).

• Athletic performance. Oral kudzu has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study in healthy males shows that taking capsules containing kudzu isoflavone extract 180 mg, soybean peptides 600 mg, taurine 200 mg, and ginseng saponins 120 mg daily in two divided doses for 15 days can significantly increase time to exhaustion during exercise when compared with placebo (57945).
• Back pain. Although there is interest in using the injectable kudzu constituent puerarin for back pain, there is insufficient reliable information about the clinical effects of oral kudzu for this condition.
• Cluster headache. Although there is interest in using oral kudzu for cluster headache, there is insufficient reliable information about the clinical effects of kudzu for this condition.
• Coronary heart disease (CHD). Although there is interest in using the injectable kudzu constituent puerarin for CHD, there is insufficient reliable information about the clinical effects of oral kudzu for this condition.
• Diabetes. It is unclear if oral kudzu is beneficial for diabetes. Details: Preliminary clinical research in adults with type 2 diabetes shows that taking oral puerarin, a kudzu constituent, 250 mg three times daily in addition to rosiglitazone 4 mg daily for 12 weeks reduces blood glucose levels and glycated hemoglobin (HbA1c) when compared to baseline (57951). The effect of kudzu alone is unclear. Additionally, the lack of a comparator group limits the validity of this finding.
• Diabetic nephropathy. It is unclear if oral kudzu is beneficial for diabetic nephropathy. Details: Preliminary clinical research in patients with diabetic nephropathy shows that taking puerarin, a kudzu constituent, 250 mg three times daily in addition to rosiglitazone 4 mg daily for 12 weeks improves laboratory measurements of kidney function, including serum creatinine, blood urea nitrogen, and urinary albumin, when compared to baseline (57951). The effect of kudzu alone is unclear. Additionally, the lack of a comparator group limits the validity of this finding.
• Hangover. Although there is interest in using oral kudzu for hangover, there is insufficient reliable information about the clinical effects of kudzu for this condition.
• Heart failure. Although there is interest in using the kudzu constituent puerarin for heart failure, there is insufficient reliable information about the clinical effects of kudzu for this condition.
• Hypertension. It is unclear if oral kudzu is beneficial for hypertension. Details: Preliminary clinical research in adults with hypertension shows that taking kudzu powder 1.5 grams twice daily for 12 weeks decreases systolic blood pressure by 16% and diastolic blood pressure by 12% when compared to baseline (92261). The validity of this finding is limited by the lack of a comparator group.
• Menopausal symptoms. Small clinical studies suggest that oral kudzu may modestly improve menopausal symptoms. Details: Preliminary clinical research shows that taking kudzu 25 mg, 50 mg, or 100 mg daily for 6 months during perimenopause improves climacteric symptoms based on a modified Green climacteric scale when compared with baseline (57890,57942). Other preliminary clinical research in patients with menopausal symptoms shows that taking kudzu extract 0.84-2.52 grams daily for 4 weeks, providing puerarin 113-338 mg daily, modestly reduces overall menopausal symptoms when compared with baseline (108154). The validity of the findings from these studies is limited by the lack of a comparator group. Other clinical research shows that taking kudzu 50 mg daily for 6 months during perimenopause reduces vasomotor symptoms similarly to taking conjugated equine estrogen 0.625 mg with or without medroxyprogesterone acetate 2.5 mg daily (57927).
• Migraine headache. It is unclear if oral kudzu is beneficial for migraine headache. Details: Preliminary clinical research in adults with migraine shows that taking one capsule of kudzu (Kuzik) daily, providing an unspecified dose of kudzu, for 90 days reduces the number of headache attacks per month by about 3, with approximately 50% of patients achieving a 50% reduction in monthly headache days when compared with baseline. There were also modest improvements in disability and medication use (108155). The validity of these findings is limited by the lack of a comparator group.
• Myocardial infarction (MI). Although there is interest in using the injectable kudzu constituent puerarin for MI, there is insufficient reliable information about the clinical effects of oral kudzu for this condition.
• Obesity. It is unclear if oral kudzu is beneficial for obesity. Details: Preliminary clinical research in adults with obesity shows that taking a kudzu extract 300 mg daily for 12 weeks reduces visceral fat and body mass index (BMI) when compared with placebo. However, doses of 200 mg do not seem to be as effective (57954).
• Postmenopausal conditions. It is unclear if oral or intravaginal kudzu is beneficial for postmenopausal conditions. Details: A small clinical study in postmenopausal individuals shows that taking kudzu containing isoflavones 100 mg orally once daily for 3 months improves flexible thinking and attention when compared with control. However, it does not appear to improve total cholesterol, low-density lipoprotein (LDL) cholesterol, or sex hormone levels (11386). Another small clinical study in postmenopausal individuals shows that taking kudzu 20 mg, 30 mg, or 50 mg daily for 24 weeks improves vaginal dryness and pH when compared with baseline, but not when compared with placebo. It also decreases a specific biomarker of bone turnover, called bone alkaline phosphatase, when compared with placebo (57924,57929). It is unclear if this correlates with improved bone density or with a reduced risk of osteoporosis. Kudzu has also been evaluated as an intravaginal gel. One small clinical study shows that applying 0.5 grams of kudzu 6% gel into the vagina every night for 2 weeks, followed by 3 nights each week for 9 weeks, improves vaginal symptoms of dryness, soreness, irritation, and abnormal discharge similarly to conjugated estrogen cream applied on the same schedule. However, kudzu gel is less effective than conjugated estrogen cream for improving overall vaginal health (96740). Another small clinical study of postmenopausal patients shows that applying 0.5 grams of kudzu 6% gel intravaginally every night for 3 weeks increases vaginal arterial blood flow and restores atrophic vaginal tissue when compared with placebo after 12 weeks (110702). In contrast, a similar study shows that applying 0.5 grams of kudzu 5% gel into the vagina every night for 2 weeks, followed by 3 nights each week for 10 weeks, does not improve vaginal symptoms when compared with placebo gel (105521). However, the study may have been inadequately powered to detect a difference between groups.
• Rhinosinusitis. Although there is interest in using oral kudzu for rhinosinusitis, there is insufficient reliable information about the clinical effects of kudzu for this condition.
• Stroke. Although there is interest in using the injectable kudzu constituent puerarin for stroke, there is insufficient reliable information about the clinical effects of oral kudzu for this condition. More evidence is needed to rate kudzu for these uses.

• Angina. It is unclear if oral Terminalia arjuna is beneficial in patients with angina. Details: Low-quality clinical research in patients with angina shows that taking Terminalia arjuna extract 500-2000 mg orally daily for 3 months reduces the frequency of angina symptoms by 50% to 71% when compared with baseline. These results were similar to taking conventional therapy (2502,2503). Other preliminary research in adults with chronic stable angina shows that taking Terminalia arjuna 500 mg orally three times daily for 7 days reduces the need for rescue treatment and improves exercise tolerance when compared with placebo. Improvements were similar to taking isosorbide mononitrate 20 mg twice daily (92833).
• Asthma. Although there has been interest in using oral Terminalia arjuna for asthma, there is insufficient reliable information about the clinical effects of Terminalia arjuna for this purpose.
• Athletic performance. It is unclear if oral Terminalia arjuna is beneficial for athletic performance. Details: A small clinical study in young regular exercising males shows that taking Terminalia arjuna extract (Oxyjun, Enovate Biolife Pvt Ltd, India) 400 mg daily for 8 weeks increases the time to exhaustion by approximately 117 seconds when compared with placebo. There were also modest improvements in feelings of perceived exertion and the left ventricular ejection fraction, a measure of blood pumped from the heart with each heartbeat (111093). It is unclear if oral Terminalia arjuna is beneficial other populations such as athletes and females.
• Coronary heart disease (CHD). It is unclear if oral Terminalia arjuna is beneficial in patients with CHD. Details: Preliminary clinical research in patients with CHD shows that taking Terminalia arjuna bark powder 500 mg orally daily for 30 days decreases levels of total cholesterol by about 10% and low-density lipoprotein (LDL) cholesterol by about 16% when compared with baseline. Taking Terminalia arjuna bark powder did not improve high-density lipoprotein (HDL) cholesterol levels (92832).
• Heart failure. The effects of Terminalia arjuna in patients with heart failure is unclear; evidence to date comes from small, short-term clinical studies, and results are conflicting. Details: Preliminary, low-quality clinical research in patients with severe, refractory congestive heart failure shows that taking Terminalia arjuna bark extract 500 mg orally three times daily for 2 weeks, as an adjunct to conventional therapy, improves left ventricular ejection fraction (LVEF) by 17% when compared with placebo (2504). However, other preliminary clinical research in adults with stage II heart failure shows that taking an extract of Terminalia arjuna bark 750 mg orally twice daily as an adjunct to conventional therapy for 12 weeks does not improve LVEF, functional class, or functional capacity when compared with placebo (96726). However, the validity of these trials is limited by short-term treatment and variation in the conventional therapies used to manage heart failure.
• Hyperlipidemia. It is unclear if oral Terminalia arjuna is beneficial for improving lipid levels. Details: Preliminary clinical research in patients with elevated cardiovascular risk factors, such as hypertension, dyslipidemia, or obesity, shows that taking Terminalia arjuna 5 grams orally twice daily for 60 days decreases levels of low-density lipoprotein (LDL) cholesterol and triglycerides by 17% and 35%, respectively, and increases high-density lipoprotein (HDL) cholesterol levels by 9%, when compared with baseline. Improvements in lipid parameters were similar to taking amlodipine 5 mg and atorvastatin 10 mg daily (109677). However, this study may have been inadequately powered to detect a difference between groups.
• Hypertension. It is unclear if oral Terminalia arjuna is beneficial for reducing blood pressure. Details: Preliminary clinical research in patients with elevated cardiovascular risk factors such as hypertension, dyslipidemia, or obesity, shows that taking Terminalia arjuna 5 grams orally twice daily for 60 days reduces systolic and diastolic blood pressure by 11% and 14%, respectively, when compared with baseline. Improvements in blood pressure were similar to taking amlodipine 5 mg and atorvastatin 10 mg daily (109677). However, this study may have been inadequately powered to detect a difference between groups.
• Obesity. It is unclear if oral Terminalia arjuna is beneficial for weight loss. Details: Preliminary clinical research in patients with elevated cardiovascular risk factors, such as hypertension, dyslipidemia, or obesity, shows that taking Terminalia arjuna 5 grams orally twice daily for 60 days reduces body mass index (BMI) by 6% when compared with baseline. Improvements in BMI were similar to taking amlodipine 5 mg and atorvastatin 10 mg daily (109677). This study may have been inadequately powered to detect a difference between groups. More evidence is needed to rate Terminalia arjuna for these uses.

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 (12595,19245,113112,113113).

CALCIUM CHANNEL BLOCKERS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.  Details Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects (12595,19245).

DIGOXIN (Lanoxin) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.  Details Hawthorn appears to improve cardiac output (12595); however, hawthorn does not appear to affect digoxin pharmacokinetics (19249). Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels (113112,113113).

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, kudzu may increase the risk of bleeding if used with antiplatelet or anticoagulant drugs.  Details Kudzu isoflavones are reported to have antiplatelet activity (13278,13291).

ANTIDIABETES DRUGS Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, taking kudzu with antidiabetes drugs might increase the risk of hypoglycemia.  Details Kudzu might lower blood glucose levels and have additive effects in patients treated with antidiabetic agents (13285,13292,57868,57951). The dose of diabetes medications might need to be adjusted.

CAFFEINE Interaction Rating = Moderate Be cautious with this combination. Severity = Mild •  Occurrence = Probable •  Level of Evidence = D Theoretically, taking kudzu with caffeine might increase levels of caffeine.  Details In healthy males injected with the kudzu constituent puerarin, caffeine clearance and metabolism is inhibited (23583). This effect has been attributed to inhibition of cytochrome P450 1A2 (CYP1A2) enzyme, which is involved in caffeine metabolism. It is unclear if taking kudzu orally would have this same effect.

ESTROGENS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, kudzu might alter the effects of estrogen therapy.  Details Some research suggests that kudzu has estrogenic effects (11386,57874,57877). This may enhance or inhibit the effects of estrogen therapy.

HEPATOTOXIC DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use might have additive hepatotoxic effects.  Details There is some concern that kudzu can adversely affect the liver (88777,92259,92260,92262).

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).
Orally, severe bradycardia, bradypnea, and Mobitz type 1 second degree heart block have been reported in a 16-year-old female who consumed Hawthorn root extract. Blood tests indicated plasma digoxin levels in the therapeutic range, despite no history of digoxin use. Medical treatment for digoxin cardiotoxicity did not improve symptoms. Symptoms gradually normalized over 3 days after discontinuation of the product (113112). Similarly, a 40-year-old female presented with bradycardia and elevated plasma digoxin levels after taking hawthorn root extract 196 mg daily for 2 days with no history of digoxin use. Symptoms resolved within 24 hours (113113).
