Below is general information about the adverse effects of the known ingredients contained in the product LiverClean. 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, there is limited information available about the adverse effects of blessed thistle when used in medicinal amounts.
Dermatologic ...Topically, blessed thistle can cause an allergic reaction, such as dermatitis, in individuals sensitive to the Asteraceae/Compositae family. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs (12).
Gastrointestinal ...Orally, when blessed thistle is used in doses higher than 5 grams per cup of tea, it can cause stomach irritation and vomiting (12).
Immunologic ...Blessed thistle can cause allergic reaction in individuals with sensitivity to the Asteraceae/Compositae family, which includes ragweed, chrysanthemums, marigolds, daisies, and many other herbs (12).
General
...Orally, boldo is generally well tolerated when used in amounts commonly found in foods.
However, when used in medicinal amounts, boldo can cause significant adverse effects such as hepatotoxicity. There is currently a limited amount of information on the adverse effects of topical boldo; however, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Abdominal pain, nausea, vomiting.
Topically: Dermatitis.
Severe Adverse Effects (Rare):
Orally: Hepatotoxicity, jaundice.
Cardiovascular ...In one report, a 39-year-old obese female developed palpitations and syncope after taking a weight loss supplement containing a combination of boldo, dandelion, and bladderwrack for 3 weeks. The patient was found to have prolonged QT-interval on ECG and frequent episodes of sustained polymorphic ventricular tachycardia (14321). It is not clear whether boldo, another ingredient, or the combination of ingredients is responsible for this adverse effect. The product was not analyzed to determine the presence of any potential toxic contaminants.
Dermatologic ...Topically, boldo can be irritating when applied to the skin (4). In one case report, a healthy 64-year-old patient experienced allergic contact dermatitis in an airborne pattern on the face, arms, and dorsum of both hands following airborne exposure to boldo. After exposure to boldo was avoided, the dermatitis resolved (106433).
Gastrointestinal ...In one case report, a manufacturer of an herbal laxative reformulated their product to contain boldo. Within 5 months of switching to this reformulated product, an 82-year-old male developed abdominal discomfort with gastrointestinal upset including heartburn (13178). In another case, a 72-year-old female reported nausea, vomiting, and anorexia, which were thought to be associated with hepatotoxic effects of a boldo infusion (100304).
Hepatic ...Orally, boldo is thought to potentially cause hepatotoxicity. The volatile oil from the boldo leaf contains the liver toxin, ascaridole. In one case report, a manufacturer of an herbal laxative reformulated their product to contain boldo. Within 5 months of switching to this reformulated product, an 82-year-old male with mild hepatic steatosis and very small gallbladder stones developed elevated liver transaminase levels. Levels normalized following discontinuation of the herbal product (13178). Several other cases of hepatotoxicity have been reported in elderly patients who received infusions of boldo leaves. These patients presented with elevated liver transaminase and bilirubin levels, sometimes up to 200 times the upper limit of normal, as well as nausea, vomiting, anorexia, asthenia, and jaundice. Lab tests and symptoms normalized a few days after stopping boldo (100304,106431).
Immunologic ...Boldo intake has been linked to one case of IgE-mediated anaphylactic allergic reaction (13185).
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
...Orally, dandelion seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, heartburn, and stomach discomfort.
Topically: Dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis in sensitive individuals.
Cardiovascular ...In one report, a 39-year-old obese woman developed palpitations and syncope after taking a weight loss supplement containing a combination of dandelion, bladderwrack, and boldo for 3 weeks. The patient was found to have prolonged QT-interval on ECG and frequent episodes of sustained polymorphic ventricular tachycardia (14321). It is not clear whether dandelion, another ingredient, or the combination of ingredients is responsible for this adverse effect. The product was not analyzed to determine the presence of any potential toxic contaminants.
Dermatologic ...Topically, dandelion can cause contact dermatitis and erythema multiforme in sensitive individuals. Dandelion can cause an allergic reaction in individuals sensitive to the Asteraceae/Compositae family (13478,13481,42893,46945,46977). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.
Endocrine ...In one report, a 56-year-old man with renal impairment developed hyperoxalaemia and peripheral gangrene after ingesting large amounts of dandelion tea (10 to 15 cups daily for 6 months). The adverse effect was attributed to the high oxalate content of dandelion tea (258 mcmol/L) and reduced renal oxalate clearance caused by renal impairment (90639). In another report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemic symptoms 2 weeks after beginning to eat salads containing dandelion (46960). The hypoglycemic effect was attributed to the potential alpha-glucosidase inhibitory activity of dandelion.
Gastrointestinal ...Gastrointestinal symptoms, including stomach discomfort, diarrhea, and heartburn, have been reported following oral use of dandelion (19146,36931). A case of intestinal blockage has been reported for a patient who ingested a large amount of dandelion greens three weeks after undergoing a stomach operation (46981). Also, a case of hemorrhagic cystitis has been reported for a 33-year-old woman who took a specific herbal product (Slim-Kombu, Balestra and Mech, Vicenza, Italy) containing 20 herbal extracts, including dandelion extract. Symptoms resolved after the patient discontinued using the product, and symptoms resumed when the patient began taking the supplement again four months later. While various ingredients in the supplement may have contributed to the symptoms, it is possible that dandelion extract may have contributed to the effect due to its diurectic, laxative, cholagogue, and antirheumatic properties (46959).
Other ...Orally, products containing dandelion pollen can cause allergic reactions, including anaphylaxis (13479,13480). Also, rhinoconjunctivitis and asthma have been reported after handling products such as bird feed containing dandelion and other herbs, with reported positive skin tests for dandelion hypersensitivity (46948). Dandelion pollen may cause pollinosis, such as allergic rhinitis and conjunctivitis (18065,46951,46964,46966,46972).
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 and topically, fennel seems to be well tolerated.
Most Common Adverse Effects:
Orally: Gastrointestinal discomfort, photosensitivity, and allergic reactions in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Seizures.
Dermatologic ...Advise patients to avoid excessive sunlight or ultraviolet light exposure while using fennel (19). Allergic reactions affecting the skin such as atopic dermatitis and photosensitivity may occur in patients who consume fennel (6178,49507).
Gastrointestinal ...Orally, fennel may cause gastrointestinal complaints, including nausea and vomiting (19146,104196).
Hematologic ...Methemoglobinemia has been reported in four infants following intoxication related to ingestion of a homemade fennel puree that may have been made from improperly stored fennel (49444).
Immunologic ...A case report describes an 11-year-old male who developed an allergy to fennel-containing toothpaste. Immediately after using the toothpaste, the patient experienced sneezing, coughing, itchy mouth, rhinorrhea, nasal congestion, wheezing, difficulty breathing, and palpitations, which resolved within 10 minutes of spitting out the toothpaste and rinsing the mouth. In challenge tests, the patient reacted to chewing fresh fennel root, but not ground fennel seeds (103822).
Neurologic/CNS ...Orally, fennel oil has been associated with tonic clonic and generalized seizures (12868). New-onset cluster headaches are reported in a 24-year-old female while using a toothpaste containing fennel and camphor for 3 months. The headaches resolved upon stopping the toothpaste (112368). It is unclear if this adverse effect can be attributed to fennel, camphor, or the combination.
Pulmonary/Respiratory ...Orally, fennel and fennel seed have been reported to cause bronchial asthma (49478).
General ...Orally, radish seems to be well tolerated when used in moderate amounts.
Gastrointestinal ...Large amounts of radish may cause irritation of the gastrointestinal mucus membrane (18). Mild indigestion has also been associated with use of a specific product containing radish, camu camu, acerola, honey, and tapioca in clinical research. However, it is unclear if this adverse event is due to radish, other ingredients in the product, or the combination (94290).
Immunologic ...A case of allergy to oral intake of radish has been reported. Symptoms included throat tightness and generalized urticaria (94289).
General
...Orally, wild yam is generally well tolerated.
Most Common Adverse Effects:
Orally: Fever, headache, upset stomach, and vomiting.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis.
Gastrointestinal ...Orally, wild yam can cause upset stomach and vomiting, especially at higher doses (12,86450).
Hematologic ...In one case report, a 55-year-old female with protein S deficiency and systemic lupus erythematosus (SLE) had temporary vision loss in the left eye from hemiretinal vein thrombosis 3 days after taking a combination phytoestrogen product containing wild yam 276 mg, dong quai 100 mg, red clover 250 mg, and black cohosh 250 mg (13155). It is unclear if wild yam contributed to this event.
Immunologic ...There are three case reports of anaphylaxis after ingestion of cooked wild yam (96722).
Neurologic/CNS ...Orally, wild yam can cause headache and fever, especially at higher doses (86450).
