POSSIBLY EFFECTIVE

• Hypertension. Oral pomegranate juice seems to modestly reduce blood pressure. Details: Most clinical research evaluating pomegranate juice for reducing systolic blood pressure (SBP) and diastolic blood pressure (DBP) shows modest benefits (8310,13023,13691,69372,69373,69374). A meta-analysis of results from eight clinical studies including 574 patients shows that pomegranate juice reduces SBP by about 5 mmHg, but does not affect DBP, when compared with placebo. Doses of pomegranate juice ranged from 43-330 mL daily for 2 weeks to 18 months. Changes in SBP and DBP were not related to the dose or duration of pomegranate juice consumption (96247).

POSSIBLY INEFFECTIVE

• Diabetes. Most oral pomegranate products do not seem to be beneficial for diabetes. It is unclear if pomegranate seed powder is beneficial. Details: A meta-analysis of clinical research shows that taking pomegranate has no effect on glycated hemoglobin (HbA1c) or plasma levels of insulin, lipids, or fasting glucose when compared with placebo in patients with type 2 diabetes. Various formulations, including juice, fruit extract, peel extract, and seed oil, were used in these studies (105265). However, a more recent clinical trial shows that drinking a beverage twice daily for 8 weeks, made by soaking a 'tea bag' containing pomegranate seed powder 5 grams in hot water for 10 minutes, modestly reduces levels of fasting blood glucose, HbA1c, total cholesterol, and triglycerides when compared with placebo. Fasting blood glucose levels were reduced by approximately 4%, compared with a 6% increase in the placebo group (105270).
• Hyperlipidemia. Oral pomegranate does not seem to be beneficial for hyperlipidemia. Details: Most clinical research shows that taking pomegranate does not increase high-density lipoprotein (HDL) cholesterol levels or reduce total cholesterol, low-density lipoprotein (LDL) cholesterol, or triglyceride levels when compared with placebo (13022,13023,13690,69142,69168,69276). A meta-analysis of results from 12 clinical studies including 545 patients with or without hyperlipidemia shows that taking pomegranate daily for at least 10 days and up to 1 year does not improve blood lipid levels when compared with placebo. Pomegranate formulations evaluated in these studies include juice, seed oil, whole fruit, extract, and vinegar beverage; no specific form or dose of pomegranate was associated with improvements in cholesterol or triglyceride levels (96248). One preliminary clinical study has evaluated pomegranate juice in combination with other fruits. Results from the study show that taking a specific pomegranate-containing combination product (Radical Fruits, Garden of Life) 900 mg orally three times daily before meals reduces total and LDL cholesterol and increases HDL cholesterol in males with hypercholesterolemia (69170). However, it is unclear if these benefits are due to pomegranate, other ingredients, or the combination.

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Atherosclerosis. It is unclear if oral pomegranate juice is beneficial for preventing atherosclerosis. Details: Preliminary clinical research shows that drinking pomegranate juice 50 mL daily reduces intima-media thickness of the carotid artery by up to 35% after one year when compared to baseline in patients with atherosclerosis and carotid artery stenosis (13023).
• Athletic performance. It is unclear if oral pomegranate extract is beneficial for athletic performance. Details: Preliminary clinical research in trained male cyclists shows that taking pomegranate extract (POM Wonderful LLC) 15 mg/kg daily for 8 days moderately reduces the amount of oxygen needed to perform submaximal exercise when compared with placebo. However, pomegranate extract does not improve performance in a timed trial (99100). Other preliminary clinical research in regionally competitive male cyclists shows that taking pomegranate extract (Pomanox P30, Euromed S.A.) 750 mg daily for 15 days increases the time to exhaustion by 94 seconds after a prolonged submaximal effort, as well as the time to reach the anaerobic threshold by about 55 seconds, when compared with placebo. There was no effect on the restoration of force or on oxygen consumption (101881).
• Chronic obstructive pulmonary disease (COPD). It is unclear if oral pomegranate juice is beneficial for COPD. Details: A small clinical trial shows that drinking pomegranate juice 400 mL daily for 5 weeks does not improve symptoms or respiratory function in patients with COPD when compared with placebo (13692).
• Coronary heart disease (CHD). It is unclear if oral pomegranate juice is beneficial for patients with CHD. Details: Some preliminary clinical research shows that drinking pomegranate juice (POM Wonderful Pomegranate Juice, POM Wonderful LLC) 240 mL daily for 3 months decreases stress-induced myocardial ischemia in patients with CHD. The average improvement in myocardial perfusion was about 17% with pomegranate juice, compared with an 18% worsening of myocardial perfusion in patients taking placebo (13691). However, other preliminary clinical research in patients with moderate CHD risk shows that drinking the same pomegranate juice product 240 mL daily for 18 months does not improve carotid intima-media thickness when compared to control (17329). It is not known if drinking pomegranate juice can prevent or reduce the risk of a myocardial infarction or other cardiovascular outcomes.
• Dental plaque. It is unclear if rinsing the mouth with pomegranate extract is beneficial for reducing dental plaque. Details: Preliminary clinical research shows that rinsing with pomegranate extract mouthwash for one minute once or twice daily reduces dental plaque in patients with or without fixed orthodontic appliances. The antiplaque activity of pomegranate extract is similar to that of chlorhexidine (69171,69316).
• Erectile dysfunction (ED). It is unclear if oral pomegranate juice is beneficial for ED. Details: In patients with mild-to-moderate ED, preliminary clinical research shows that drinking pomegranate juice daily for 4 weeks does not improve symptoms of ED when compared with placebo (69175).
• Exercise-induced muscle soreness. It is unclear if oral pomegranate juice is beneficial for reducing exercise-induced muscle soreness. Details: Preliminary clinical research shows that drinking pomegranate juice (POM Wonderful Pomegranate Juice, POM Wonderful LLC) 250 mL twice daily for 15 days reduces post-exercise muscle soreness in elbow flexor, but not knee extensor, muscles in resistance-rained males when compared with placebo (69355). However, in non-resistance trained males, drinking the same pomegranate juice 250 mL twice daily for 9 days does not reduce exercise-induced muscle damage or delayed onset soreness of elbow flexor muscles when compared with placebo (101880).
• HIV/AIDS. Although there has been interest in using oral pomegranate for HIV/AIDS, there is insufficient reliable information about the clinical effects of pomegranate for this condition.
• Influenza. Although there has been interest in using oral pomegranate for influenza prevention, there is insufficient reliable information about the clinical effects of pomegranate for this purpose.
• Intrauterine growth restriction (IUGR). It is unclear if oral pomegranate juice is beneficial for preventing brain injury in IUGR neonates. Details: In patients with an IUGR pregnancy, clinical research shows that drinking pomegranate juice 8 ounces daily from 24-34 weeks' gestation until delivery reduces the risk of an MRI-diagnosed gray matter brain injury in the infant by approximately 28%. There was no effect on brain volume or white matter injury (105267).
• Kidney failure. It is unclear if oral pomegranate juice is beneficial for patients on hemodialysis; the available research is conflicting. Details: Some preliminary clinical research shows that taking pomegranate juice (Nutrafood) 100 mL during the first dialysis treatment hour three times weekly for one year reduces antihypertensive medication requirements and the rate of second hospitalization due to infection when compared with placebo. Consuming pomegranate juice also increases high-density lipoprotein (HDL) cholesterol in patients with baseline levels of 40 mg/dL or less and reduces triglycerides in patients with baseline levels of at least 200 mg/dL (91698,91699). Preliminary clinical research also shows that taking pomegranate juice 100 mL immediately after dialysis three times weekly for 8 weeks reduces triglycerides by approximately 20%, as well as systolic and diastolic blood pressure by 5% and 7%, respectively, when compared with baseline. HDL cholesterol was also increased by approximately 23%. These changes were significant when compared with placebo (101882). However, pomegranate juice did not affect total cholesterol, low-density lipoprotein (LDL) cholesterol, liver enzymes, or incidence of cardiovascular events when compared with placebo (91698,91699,101882). Other preliminary clinical research shows that drinking pomegranate juice (POM Wonderful Pomegranate Juice, POM Wonderful LLC) 100 mL or taking pomegranate juice extract tablets (POM Wonderful LLC) 1050 mg daily prior to each dialysis session for 4 weeks does not improve blood pressure, lipids, or markers of inflammation and oxidative stress when compared to baseline in patients receiving maintenance hemodialysis (91697). Although the reason for these conflicting findings is not clear, it may have to do with the timing of consumption. The evidence suggests that offering pomegranate during dialysis or after completion of dialysis might be more effective than prior to dialysis.
• Menopausal symptoms. It is unclear if oral pomegranate seed oil or pomegranate extract is beneficial for menopausal symptoms. Details: Preliminary clinical research shows that taking a specific pomegranate seed oil (Delima, Pekana Naturheilmittel GmbH) 30 mg orally twice daily for 12 weeks does not reduce the frequency of hot flashes when compared with placebo in postmenopausal adults experiencing at least 5 hot flashes per day. However, pomegranate seed oil might improve sleep in some patients with sleep disturbances attributed to menopause (91685). A clinical study in healthy, perimenopausal and menopausal adults with untreated menopausal symptoms shows that taking pomegranate extract 3 mL three times daily for 4 weeks reduces symptoms, including hot flashes and vertigo, and improves physical and mental quality of life when compared with placebo. Additionally, these improvements were sustained 3 weeks after discontinuing treatment (108484). The validity of this study is limited by the short duration of treatment.
• Metabolic syndrome. It is unclear if oral pomegranate juice is beneficial for metabolic syndrome. Details: Preliminary clinical research shows that drinking pomegranate juice 240 mL daily for one month improves endothelial dysfunction in adolescents with metabolic syndrome when compared with drinking grape juice 240 mL daily (53174,69362).
• Muscle strength. It is unclear if oral pomegranate juice is beneficial for increasing muscle strength. Details: Preliminary clinical research shows that taking a specific pomegranate extract (POMx, POM Wonderful LLC) 480 mL twice daily modestly improves recovery of strength 2-3 days after eccentric exercise but does not reduce muscle soreness after exercise when compared with placebo (69261).
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral pomegranate seed oil or pomegranate extract improves anthropometric measures in adults with NAFLD. Details: A small clinical study in overweight and obese adults with NAFLD shows that taking a dried pomegranate extract, standardized to contain 90 mg of ellagic acid, twice daily for 12 weeks reduces body mass index and body weight when compared with placebo. A 5 kg weight reduction occurred in the pomegranate group, compared to a small increase in weight in the placebo group. Pomegranate also improved diastolic blood pressure, as well as lipid and glycemic parameters; however, the patients included in this study had normal baseline parameters, limiting the validity of this finding (108481). Pomegranate has also been evaluated in combination with other ingredients. One small clinical crossover study in obese females with NAFLD shows that taking a specific combination product (Xanthigen, Polinat) containing pomegranate seed oil 300 mg and brown marine algae 300 mg (standardized to fucoxanthin 2.4 mg) modestly reduces body weight and liver fat content when compared with placebo (69257).
• Obesity. It is unclear if oral pomegranate is beneficial for obesity. Most evidence suggests that it is not beneficial, although some studies have yielded conflicting findings. Details: A meta-analysis of 513 participants shows that taking pomegranate extract, juice, or concentrate for 2-26 weeks does not reduce body weight, body mass index, waist circumference, or body fat percentage when compared with placebo or other control (101883). However, most of these studies were not designed to investigate weight as the primary outcome, and some preliminary clinical research in overweight or obese individuals suggests that some pomegranate products might have some benefit. Drinking pomegranate juice 120 mL daily for one month helps these individuals maintain weight when compared with placebo, although it does not appear to improve glucose, insulin secretion, or insulin sensitivity (91693).
• Oropharyngeal candidiasis. It is unclear if topical pomegranate peel extract is beneficial for oropharyngeal candidiasis. Details: Preliminary clinical research in patients with candidiasis associated with denture stomatitis shows that applying a gel containing the extract of pomegranate fruit peel to the gums three times daily for 15 days seems to be as effective as miconazole gel for improving symptoms of candidiasis (13689).
• Polycystic ovary syndrome (PCOS). It is unclear if oral pomegranate juice is beneficial for PCOS. Details: In patients with PCOS, preliminary clinical research shows that taking pomegranate juice 45 mL daily for 8 weeks reduces systolic and diastolic blood pressures by 10 and 4 mmHg, respectively, when compared with a control group not taking pomegranate juice. Triglyceride and high-density lipoprotein (HDL) cholesterol levels were also modestly improved. However, there was no effect on glycemic measures, and low-density lipoprotein (LDL) cholesterol levels increased by 6 mg/dL (105266). Another clinical trial in patients with PCOS shows that taking synbiotic pomegranate juice containing inulin and lactobacillus as 2 liters weekly for 8 weeks improves insulin sensitivity, body mass index, waist circumference, and testosterone levels when compared with baseline or a control juice. However, patients consuming a drink containing only the synbiotic ingredients experienced the same improvements, whereas patients consuming only regular pomegranate juice experienced no benefits, suggesting that pomegranate was not responsible for these changes (101884).
• Prostate cancer. It is unclear if oral pomegranate extract or juice is beneficial for prostate cancer. Details: Preliminary clinical research shows that pomegranate might slow prostate cancer progression in some patients after surgery or radiation for prostate cancer. The length of time to doubling of prostate specific antigen (PSA) was longer in those who took a specific pomegranate extract (POMx, POM Wonderful LLC) 1-3 grams daily, as well as those who drank 8 ounces of pomegranate juice daily, for up to 24 months (14137,14388,91695). However, the results from a large well-designed study do not support these findings. This study shows that taking 8 ounces of a pomegranate liquid extract does not increase the length of time to doubling of PSA (105271). In patients with favorable-risk localized prostate cancer, a small clinical trial also shows that taking pomegranate fruit extract (POMx, POM Wonderful) 1000 mg daily for 12 months does not affect the length of time to doubling of PSA, although there were some changes in tumor markers of DNA damage (105269). Pomegranate has also been evaluated in combination with other ingredients. Preliminary clinical research in patients with localized prostate cancer shows that taking a combination supplement containing pomegranate powder 100 mg, broccoli powder 100 mg, turmeric powder 100 mg, and green tea extract 20 mg daily for 6 months slows the increase in PSA levels when compared with placebo (89730). It is not clear if this effect is due to pomegranate, the other ingredients, or the combination.
• Rheumatoid arthritis (RA). It is unclear if oral pomegranate extract is beneficial for RA. Details: Preliminary clinical research shows that taking a specific pomegranate extract (POMx, POM Wonderful LLC) 5 mL twice daily for 12 weeks decreases disease activity and reduces tender joint count by 62% when compared to baseline in patients with RA (91686). The validity of these findings is limited by the lack of a control group.
• Rhinosinusitis. It is unclear if intranasal pomegranate extract is beneficial for chronic rhinosinusitis. Details: A clinical study in adults with chronic rhinosinusitis or rhinitis persisting longer than 12 weeks, with or without the presence of nasal polyps, shows that using a nasal spray containing pomegranate extract in an unknown dose twice daily for 30 days does not improve objective or subjective nasal or sinus symptoms when compared with placebo nasal spray. In a subgroup of patients with chronic rhinitis, including allergic and nonallergic rhinitis, improvement in thick nasal discharge is also observed in those receiving the pomegranate nasal spray; however, the study does not report outcomes for each subtype of rhinitis (108480).
• Stroke. Although there has been interest in using oral pomegranate for stroke recovery, there is insufficient reliable information about the clinical effects of pomegranate for this purpose.
• Sunburn. It is unclear if oral pomegranate extract is beneficial for sunburn prevention. Details: A small clinical study shows that taking pomegranate extract standardized to contain ellagic acid 100-200 mg daily for 4 weeks does not reduce skin pigmentation caused by UV light exposure when compared with placebo (69172). However, this study was not adequately powered to detect a difference between treatments.
• Trichomoniasis. It is unclear if oral pomegranate extract is beneficial for trichomoniasis. Details: A very small clinical study in patients with vaginal Trichomoniasis suggests that taking pomegranate extract might help to eradicate Trichomonas vaginalis infection (69286). The validity of this finding is limited by the small study size, unclear reporting, and lack of a control group. More evidence is needed to rate pomegranate for these uses.

LIKELY SAFE ...when pomegranate fruit or fruit juice is used orally and appropriately. Pomegranate juice has been safely used in studies lasting up to 3 years (4912,8310,13022,13023,13690,14137,14388,17329,91693).

POSSIBLY SAFE ...when pomegranate extract is taken orally and appropriately. A specific pomegranate ellagitannin-enriched polyphenol extract (POMx, POM Wonderful) 1-3 grams daily has been safely used for up to 18 months (17729,69261,91686,91695,91697,99100,105269). ...when pomegranate seed oil is used orally and appropriately. Pomegranate seed oil 60 mg daily has been used with apparent safety for up to 12 weeks (91685). ...when a hot water extract of pomegranate seed powder is used orally and appropriately. Pomegranate seed powder 5 grams daily has been used with apparent safety for up to 8 weeks (105270). ...when pomegranate extract is used topically on oral mucosa (13689).

POSSIBLY UNSAFE ...when the pomegranate root, stem, and peel are used orally in large amounts. Bark of the pomegranate root and stem contains the piperidine alkaloids pelletierine, pseudopelletierine, isopelletierine, and methyl isopelletierine. These alkaloids have muscle relaxant properties that have been associated with paralysis and death in animals (13687,13694,13695). Dried pomegranate peel may contain aflatoxin, which is a potent hepatocarcinogen and toxin (92018).

PREGNANCY AND LACTATION: POSSIBLY SAFE
when the fruit or fruit juice is consumed orally and appropriately (13686,105267). There is insufficient reliable information available regarding the safety of using other forms of pomegranate or other parts of the plant during pregnancy or lactation; avoid using.

ACE INHIBITORS (ACEIs) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, taking pomegranate with ACEIs might increase the risk of adverse effects.  Details Pomegranate juice is thought to have ACE inhibitor-like effects (8310).

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, taking pomegranate with antihypertensive drugs might increase the risk of hypotension.  Details Consuming pomegranate juice can modestly lower blood pressure (8310,13023,69373,69374).

CARBAMAZEPINE (Tegretol) Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, taking pomegranate with carbamazepine might increase the risk of adverse effects, although research suggests this interaction is unlikely to be clinically significant.  Details Animal research shows that pomegranate juice may inhibit cytochrome P450 3A4 (CYP3A4) metabolism of carbamazepine and increase levels of carbamazepine by 1.5 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP3A4, but might not inhibit hepatic CYP3A4 (13188). However, some human research suggests that pomegranate does not significantly inhibit CYP3A4 drug metabolism in humans (16711,16712,17326).

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = B Theoretically, pomegranate might increase levels of drugs metabolized by CYP2C9.  Details Some animal and in vitro research shows that pomegranate juice inhibits intestinal, but not hepatic, CYP2C9 isoenzyme activity (17327). However, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans (91694).

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, pomegranate might increase levels of drugs metabolized by CYP2D6.  Details In vitro, pomegranate juice inhibits CYP2D6 (13703). However, the clinical significance of this potential interaction in humans is not known.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = B Theoretically, pomegranate might increase levels of drugs metabolized by CYP3A4, but most research suggests this interaction is unlikely to be clinically significant.  Details Pomegranate contains several polyphenols that have individually been shown to inhibit CYP3A4. However, there is contradictory evidence about the effect of whole pomegranate juice on CYP3A4 activity. In vitro, pomegranate juice significantly inhibits the CYP3A4 enzyme, with comparable inhibition to grapefruit juice (13188,16711,17326). In an animal model, pomegranate juice inhibits CYP3A4 metabolism of carbamazepine and increases levels of carbamazepine by 1.5 times (13188); however, in human volunteers, drinking a single glass of pomegranate juice 240 mL or taking 200 mL daily for 2 weeks does not significantly affect levels of the CYP3A4 substrate midazolam after oral or intravenous administration (16711,17730). Another study in healthy volunteers shows that consuming pomegranate juice 300 mL three times daily for three days also does not significantly affect levels of simvastatin, a CYP3A4 substrate (16712,91696) This suggests that pomegranate is unlikely to significantly affect levels of CYP3A4 substrates in humans (17326).

ROSUVASTATIN (Crestor) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, taking pomegranate with rosuvastatin might increase the risk of adverse effects.  Details In one case, a patient taking rosuvastatin 5 mg every other day in combination with ezetimibe 10 mg daily developed rhabdomyolysis after drinking pomegranate juice 200 mL twice weekly for 3 weeks. This patient had a history of elevated creatine kinase levels while not receiving any statin treatment. This suggests a possible underlying myopathy and predisposition to rhabdomyolysis (14465).

TOLBUTAMIDE (Orinase) Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, pomegranate might increase levels of tolbutamide, although research suggests this interaction is unlikely to be clinically significant.  Details Animal research shows that pomegranate juice inhibits the cytochrome P450 2C9 (CYP2C9) metabolism of tolbutamide. Pomegranate juice increased tolbutamide levels by 1.2 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP2C9, but might not inhibit hepatic CYP2C9 (17327). Despite this evidence, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans (91694). This interaction does not appear to be clinically significant in humans.

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, pomegranate might increase warfarin levels and increase the risk of bleeding. Also, discontinuing regular consumption of pomegranate juice might decrease warfarin levels.  Details In one case report, a patient had a stable, therapeutic bleeding time, as measured by international normalized ratio (INR), while taking warfarin in combination with pomegranate juice 2-3 times per week. The patient became subtherapeutic within about 10 days after discontinuing pomegranate juice, which required a warfarin dose increase (17328). In another case report, a patient with a stable INR for over one year presented with an INR of 14. The patient noted no changes to medications or diet but did report consuming around 3 liters of pomegranate juice over the previous week. The patient's INR stabilized upon moderation of pomegranate juice consumption (24273). The mechanism of this potential interaction is unclear.

General ...Orally, pomegranate fruit juice is generally well tolerated. Pomegranate fruit extract and seed oil seem to be well tolerated. Pomegranate root, stem, and peel should not be used orally in large amounts. Topically, pomegranate fruit extract seems to be well tolerated.
Most Common Adverse Effects:
Oral: Diarrhea, flatulence.

Cardiovascular ...In one clinical trial, 2% of patients experienced hyperlipidemia and hypertension after consumption of pomegranate juice (69175). However, most clinical research shows that pomegranate does not increase cholesterol or blood pressure and may actually improve these parameters in some patients (8310,13022,13023,69168,69373,69374).

Dermatologic ...Topically, pomegranate may cause urticaria (hives) in some patients (8445).

Gastrointestinal ...Orally, pomegranate may cause mild gastrointestinal adverse effects. In one clinical study, drinking pomegranate juice 8 ounces daily caused diarrhea and flatulence in 2% of patients (69175). In another clinical study, taking pomegranate extract (POMx, POM Wonderful LLC) 3000 mg daily caused diarrhea in 10% of patients. This dose of pomegranate extract also caused nausea, abdominal pain, constipation, gastrointestinal upset, and vomiting in a small number of patients (91695).

Immunologic ...Orally, pomegranate fruit or seeds may cause allergic reactions. These allergic reactions occur more commonly in people who are allergic to other plants (7674). In rare cases, pomegranate fruit can cause angioedema. Angioedema seems to occur without warning and in people who have eaten pomegranate for many years. Patients should be told to stop eating pomegranate if swelling of the tongue or face develops (7673). In one report, a patient experienced pomegranate-dependent, exercise-induced anaphylaxis. The patient developed widespread urticaria (hives) and lip edema after eating pomegranate seeds and then exercising (17331). In another report, an atopic patient experienced an allergic reaction to pomegranate fruit. Symptoms included urticaria (hives), facial angioedema, and hypotension (91692).
Topically, pomegranate may cause contact hypersensitivity characterized by urticaria (hives), angioedema, rhinorrhea, red itchy eyes, and dyspnea arising within a few minutes of exposure (8445).

Pulmonary/Respiratory ...Orally, pomegranate juice may cause nasal congestion, but this event is rare. In one clinical study, pomegranate juice was associated with nasal congestion in 2% of patients (69175). There is also one case report of a 7-year-old asthmatic child who developed bronchospasm moments after ingesting several pomegranate seeds (69149).
