Below is general information about the adverse effects of the known ingredients contained in the product Barberry Plus Capsule. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, black walnut fruit (nut) is well tolerated.
However, the leaf, bark, and hull of black walnut contain high quantities of tannins, which may cause adverse effects when used orally or topically.
Most Common Adverse Effects:
Orally: The leaf, bark, and hull can cause gastrointestinal upset.
Topically: Hull preparations may cause a temporary yellow or brown discoloration at the site of application. The leaf, bark, and hull can cause skin irritation.
Serious Adverse Effects (Rare):
Orally: The bark may increase the risk for tongue cancer or lip leukoplakia when used long-term.
All routes of administration: Allergic reactions, including anaphylaxis.
Dermatologic ...Topically, black walnut leaf, bark, or hull may have an irritating effect on the skin due to tannin content. Black walnut hull preparations might cause a temporary yellow or brown discoloration of the skin at the site of application (12).
Gastrointestinal ...Orally, black walnut leaf, bark, or hull may cause gastrointestinal upset due to tannin content (12). Also, daily use of the juglone-containing bark of a related species (English walnut) is associated with increased risk of tongue cancer and lip leukoplakia (2,12).
Hepatic ...Orally, black walnut leaf, bark, or hull may cause liver damage if taken for extended periods of time due to tannin content (12).
Immunologic ...Tree nuts, which include black walnuts, can cause allergic reactions in sensitive individuals. Due to the prevalence of this allergy in the general population, tree nuts are classified as a major food allergen in the United States (105410).
Renal ...Orally, black walnut leaf, bark, or hull may cause kidney damage if taken for extended periods of time due to tannin content (12).
General
...Orally, Ceylon cinnamon is generally well tolerated, and adverse reactions are uncommon.
Most Common Adverse Effects:
Orally: Bloating, dyspepsia, nausea.
Topically: Allergic dermatitis, irritation of mucous membranes and skin.
Dermatologic
...Orally, a case of systemic contact dermatitis has been reported in a patient who consumed cinnamon (type not specified) after being previously sensitized to cinnamyl alcohol via cutaneous exposure (95599).
In a small study of oral Ceylon cinnamon, two patients reported itching (104520). In another small study, two patients reported rashes (108263).
Topically, cinnamon oil can cause skin irritation and allergic dermatitis, probably due to cinnamaldehyde which makes up 60% to 80% of cinnamon oil (2537,12635,92071,95596,95599). In one case report, a 16-year-old female experienced worsening dermatitis after using a homemade facial scrub containing cinnamon powder (type not specified). Symptoms improved after discontinuation of the scrub (95596). Several cases of intraoral allergic contact dermatitis have been reported in patients consuming cinnamon (type not specified) or using products containing constituents of cinnamon (95598).
Gastrointestinal ...Orally, gastrointestinal side effects such as heartburn, nausea, bloating, and dyspepsia have been reported (97250).
Hematologic ...Orally, a case of postoperative hemorrhage is reported in a 49-year-old patient after taking Ceylon cinnamon 1 tablespoon daily for 10 months. One day post-colectomy, the patient had an INR of 1.59 and intraabdominal bleeding that required exploratory laparotomies, blood transfusion, and fresh frozen plasma. Ultimately, the patient was discharged (112421).
Hepatic ...While there is concern about the coumarin content in cassia cinnamon increasing the risk for hepatic adverse effects and bleeding, the amount of coumarin in Ceylon cinnamon is negligible and unlikely to cause toxic effects (89652,92072,92073). In one case report, a 73-year-old female taking rosuvastatin for several months developed elevated liver function tests (LFTs), abdominal pain, nausea, and vomiting after taking cinnamon (unknown dose and type) for 7 days. The acute hepatitis and elevated LFTs resolved after stopping both cinnamon and rosuvastatin. The patient was later able to resume rosuvastatin without recurrence (97249).
General
...Orally, clove is well tolerated when consumed as a spice; however, clove oil in doses of only 5-10 mL can be toxic in children.
Topically, clove is generally well tolerated. When inhaled or used intravenously, clove may be unsafe.
Most Common Adverse Effects:
Topically: Burning, contact dermatitis, dental decay, itching, mucous membrane irritation, tingling, ulcers.
Inhaled: Dental decay, hypertension, itching, tachycardia.
Serious Adverse Effects (Rare):
Orally: Liver failure, respiratory distress.
Inhaled: Pneumonitis, pulmonary edema, respiratory distress.
Cardiovascular ...Smoking clove cigarettes increases heart rate and systolic blood pressure (12892).
Dental ...Population research has found that the risk of dental decay is increased in clove cigarette smokers (43332). Repeated topical application of clove in the mouth can cause gingival damage and skin and mucous membrane irritation (4,272,512). Eugenol, a constituent of clove and a material commonly found in dentistry, has been associated with side effects including gum inflammation and irritation (43365,43373,43522).
Dermatologic ...The American Dental Association has accepted clove for professional use, but not nonprescription use, due to potential damage to soft tissue that may be induced by clove application. In clinical research, small aphthous-like ulcers appeared in the area of the mouth where clove gel was applied in four participants (43448). Skin irritation and stinging have been reported with clove oil application (43338,43626). In a 24-year-old, exposure to a clove oil spill resulted in permanent local anesthesia and anhidrosis, or lack of sweating, at the affected area (43626).
Endocrine ...A case of hypoglycemia and metabolic acidosis have been reported after administration of one teaspoon of clove oil to a seven-month-old infant (43457). A case of electrolyte imbalance following accidental ingestion by a seven-month-old has also been reported (6).
Hematologic ...A case of disseminated intravascular coagulation has been reported in a 2-year-old patient after consuming between 5-10 mL of clove oil. The patient was treated with heparin, fresh frozen plasma, protein C, factor VII, and antithrombin III. On the fifth day, the patient started to improve and made a full recovery (43652).
Hepatic ...There are three cases of hepatic failure occurring in children after ingestion of 5-10 mL of clove oil (43395,43419,43652). Liver injury also occurred in a 3-year-old male (96949). These patients were successfully treated with N-acetylcysteine. The course of liver injury seems to be milder and shorter with early N-acetylcysteine treatment (43395,43419,96949). Another patient, who also presented with disseminated intravascular coagulation, was successfully treated with heparin, fresh frozen plasma, protein C, factor VII, and antithrombin III (43652).
Immunologic ...Contact dermatitis and urticaria has been reported following topical exposure to clove oil or eugenol, a constituent of clove oil (12635,43339,43606,43346).
Neurologic/CNS ...CNS depression has been reported in a 7-month-old who was given one teaspoon of clove oil accidentally in place of mineral oil for diarrhea. The patient was successfully treated with supportive care and gastric lavage (43457). A case of confusion and inability to speak has been reported secondary to oral exposure to clove oil and alcohol. The patient required intubation and was successfully treated with thiamine and normal saline (43580). Seizure and coma have been reported in a two-year-old male after ingesting 5-10 mL of clove oil (43652).
Pulmonary/Respiratory
...Clove cigarettes have been associated with throat and chest tightness (43337), pulmonary edema (43618), and fatal aspiration pneumonitis (43599).
The causative factor may be clove alone or clove along with other substances found in cigarettes. Clove cigarettes contain significant amounts of nicotine, tar, and carbon monoxide and increase plasma levels of nicotine and exhaled carbon monoxide, which might cause long-term health effects similar to tobacco smoking (12892). According to the American Medical Association, inhaling clove cigarette smoke has been associated with severe lung injury in a few susceptible individuals with prodromal respiratory infection. Also, some individuals with normal respiratory tracts have apparently suffered aspiration pneumonitis as the result of a diminished gag reflex induced by a local anesthetic action of eugenol, which is volatilized into the smoke (43602).
Intravenous injection of clove oil in a 32-year-old female resulted in hypoxia, acute dyspnea, interstitial and alveolar infiltrates, and non-cardiogenic pulmonary edema. The patient was managed with supplemental oxygen and recovered over the next seven days (16384).
Occupational exposure to eugenol, a constituent of clove, has also been reported to cause asthma and rhinitis (43492).
Renal ...Proteinuria and other urinary abnormalities were observed in a seven-month-old infant given one teaspoon of clove oil accidentally in place of mineral oil for diarrhea. The patient was successfully treated with supportive care and gastric lavage (43457).
General ...European barberry is generally well tolerated when consumed in amounts commonly found in food. A thorough evaluation of safety outcomes has not been conducted for the use of larger, medicinal amounts. Topically, European barberry seems to be well tolerated.
Hepatic ...Orally, a case of hepatitis-associated aplastic anemia is reported in an adult male after consuming European barberry 15 drops and nannari root 15 drops twice a day for 2 weeks. The patient presented with lethargy, loss of appetite, and jaundice that progressed to high-grade fevers, chills, rigors, severe pancytopenia, and abnormal liver function tests. Liver biopsy was suggestive of drug-induced liver injury. The patient was hospitalized for multiple infections and symptomatic thrombocytopenia. Despite receiving supportive care, blood transfusions, and corticosteroids, the patient died 7 weeks after diagnosis (110021). The exact reason for this adverse effect is not clear.
General
...Orally, pumpkin products are generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal discomfort, diarrhea, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis.
Dermatologic ...There are two case reports of adult females developing substantial transient hair loss 1-3 weeks after consumption of a meal containing either bitter-tasting pumpkin or undefined squash. This adverse effect was attributed to a high concentration of cucurbitacin, which is commonly found in wild pumpkins (104535).
Gastrointestinal ...Orally, pumpkin seed oil has been reported to cause mild abdominal discomfort in clinical trials (5093,92378). There are also two case reports of adults developing severe nausea, vomiting, and diarrhea following consumption of a meal containing either bitter-tasting pumpkin or undefined squash. These adverse effects were attributed to a high concentration of cucurbitacin, which is commonly found in wild pumpkins (104535).
Immunologic
...Orally, pumpkin seed oil and pumpkin pulp have been reported to cause anaphylactic reactions in children and adults.
A case review highlights 4 cases of anaphylaxis in children (3 from pumpkin pulp, 1 from pumpkin seeds), and 7 cases in adults (1 from pumpkin flesh, 6 from pumpkin seeds). Symptoms of anaphylaxis include urticaria, angioedema of the lips or face, dyspnea, dysphagia, and oropharyngeal itching and swelling. A case report describes a 2-year-old male presenting with urticaria, swollen lips, and increased dyspnea 10 minutes after ingesting pumpkin seeds. The patient was found to have elevated allergen-specific immunoglobulin E (IgE) and a positive skin-prick test for pumpkin seeds. Symptoms resolved after treatment with epinephrine, systemic glucocorticoids, salbuterol, and antihistamines (107843).
There may also be concern for allergic reaction due to inhalation or topical exposure. One case report describes an 8-year-old child developing anaphylaxis while carving a pumpkin; another highlights that inhalation of pumpkin seed flour may have potentiated anaphylaxis in 3 individuals following the ingestion of pumpkin seeds (107843). Further research is necessary to assess the relationship between anaphylaxis and route of administration.
