• Atopic dermatitis (eczema). Although there is interest in using topical burdock for eczema, there is insufficient reliable information about the clinical effects of burdock for this condition.
• Breast cancer. Oral burdock root has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Population research in breast cancer patients has found that using a specific product containing burdock root, sheep sorrel, slippery elm bark, and Indian rhubarb (Essiac, Resperin Canada Limited) is not associated with improved quality of life when compared with no intervention (37419).
• Common cold. Although there is interest in using oral burdock for symptoms of the common cold, there is insufficient reliable information about the clinical effects of burdock for this condition.
• Diabetes. Although there is interest in using oral burdock for diabetes, there is insufficient reliable information about the clinical effects of burdock for this condition.
• Diverticulitis. It is unclear if oral burdock is beneficial in patients with diverticulitis. Details: A small open-label clinical study in patients with colonic diverticulitis shows that taking burdock tea (Ajikan, Co., Ltd.) providing 1.5 grams three times daily for a median of 26 months is associated with an acute diverticulitis recurrence rate of 11%, compared with 32% of those not taking burdock tea. Furthermore, the recurrence-free duration was increased by about 14 months. However, taking burdock tea for a median of 16 months does not prevent colonic diverticular bleeding recurrence (102696).
• Dry skin. Although there is interest in using topical burdock for dry skin, there is insufficient reliable information about the clinical effects of burdock for this purpose.
• Gout. Although there is interest in using oral burdock for gout, there is insufficient reliable information about the clinical effects of burdock for this condition.
• Hepatitis. Although there is interest in using oral burdock for hepatitis, there is insufficient reliable information about the clinical effects of burdock for this condition.
• Metabolic syndrome. It is unclear if oral burdock is beneficial in patients with metabolic syndrome. Details: A very small clinical study in patients with metabolic syndrome shows that drinking burdock extract 100 mL three times daily after meals for 16 weeks does not reduce body weight, abdominal fat, blood pressure, lipid levels, or glucose when compared with baseline or control (105667).
• Obesity. Although there is interest in using oral burdock for obesity, there is insufficient reliable information about the clinical effects of burdock for this condition.
• Urinary tract infections (UTIs). Although there is interest in using oral burdock for UTI, there is insufficient reliable information about the clinical effects of burdock for this condition.
• Vaginitis. Topical burdock has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Observational research in adults and children with vaginitis has found that applying a specific solution containing burdock, chamomile, and aloe (Zelesse, ITF Research Pharma S.L.U., Alcobendas) to the vaginal area once or twice daily for 5-20 days is associated with moderate improvements in symptoms such as pruritus, erythema, and discharge when compared with baseline (102695,102697). The validity of this finding is limited by its observational nature and the lack of a control group. More evidence is needed to rate burdock for these uses.

• Constipation. Although there has been interest in using oral dandelion for constipation, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
• Dyspepsia. Although there has been interest in using oral dandelion for dyspepsia, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
• Flatulence. Although there has been interest in using oral dandelion for flatulence, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
• Heart failure. Although there has been interest in using oral dandelion for its diuretic effects in patients with heart failure, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
• Joint pain. Although there has been interest in using oral or topical dandelion for joint pain, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
• Postoperative pain. It is unclear if topical dandelion is beneficial in patients with pain after jaw surgery. Details: A small clinical study in patients undergoing maxillofacial surgery shows that topical application of dandelion combined with borneol one time on the day of surgery and twice daily on the first and second days after surgery for 30 minutes does not reduce maxillofacial pain when compared with cold compresses or either ingredient alone (112484). The validity of this finding is limited by concurrent use of opioid analgesic and nonsteroidal anti-inflammatory medications.
• Postoperative swelling. It is unclear if topical dandelion is beneficial in patients with swelling after jaw surgery. Details: A small clinical study in patients who underwent maxillofacial surgery shows that topical application of dandelion combined with borneol one time on the day of surgery and twice daily on the first and second days after surgery for 30 minutes modestly reduces facial swelling and improves mouth opening abilities when compared with cold compresses or borneol alone (112484). It is unclear whether this effect is due to dandelion, borneol, or the combination.
• Tonsillitis. It is unclear if oral dandelion is beneficial in patients with tonsillitis. Details: One small clinical study in patients with acute purulent tonsillitis shows that eating soup containing dandelion (pugongying soup) daily for 3 days along with benzylpenicillin sodium 640,000 units daily improves recovery when compared with placebo plus benzylpenicillin sodium. Recovery rates were 36% with the dandelion-containing soup compared to 10% with placebo (18292).
• Urinary tract infections (UTIs). Oral dandelion has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in females with recurrent UTIs shows that taking a specific combination of dandelion root and uva ursi leaf extracts three times daily for 1 month reduces the risk of UTI recurrence when compared with placebo at 12-month's follow-up. For every 5 patients treated with this combination over placebo, one additional UTI was prevented (1932). In this combination, uva ursi is used for its antibacterial properties and dandelion is used to increase urination. However, this combination is not recommended for extended use because uva ursi may be unsafe when used long-term. Another small clinical study in premenopausal females with acute, uncomplicated lower UTIs shows that taking a combination product containing dandelion extract 50 mg, D-mannose, prebiotics, arabinogalactan, and astragalus root extract twice daily for five days, along with phenazopyridine and alkylating agents as conventional therapy, improves UTI symptoms and bacteriuria when compared with placebo plus conventional therapy (111757). It is unclear if these effects are due to dandelion, other ingredients, or the combination. More evidence is needed to rate dandelion for these uses.

• Acne. It is unclear if oral European barberry fruit is beneficial for acne. Details: Preliminary clinical research in adolescents 12-17 years of age with moderate or severe acne shows that taking European barberry aqueous extract 200 mg three times daily for 4 weeks reduces acne severity and decreases the number of acne lesions when compared with placebo (94824).
• Bacterial vaginosis. It is unclear if topical European barberry is beneficial for bacterial vaginosis. Details: A small clinical study in adults with bacterial vaginosis shows that applying 5 grams of a cream containing European barberry 5% with metronidazole 0.75% vaginally nightly for 7 days modestly reduces infection recurrence rate over the following three weeks when compared with metronidazole cream alone (94826).
• Breast cancer. Although there is interest in using oral European barberry for breast cancer prevention, there is insufficient reliable information about the clinical effects of European barberry for this condition.
• Dental plaque. It is unclear if brushing the teeth with a gel containing European barberry is beneficial for dental plaque. Details: Preliminary clinical research in males 11-12 years of age shows that brushing with a European barberry extract gel containing berberine 1%, three times daily for 3 weeks reduces plaque index when compared with placebo. This effect was similar to that seen with a commercial antiplaque toothpaste (Colgate) (33695).
• Diabetes. It is unclear if oral European barberry is beneficial for diabetes. Details: A small clinical study in adults with type 2 diabetes shows that taking European barberry juice 200 mL daily for 8 weeks, in conjunction with standard treatment, reduces fasting blood glucose levels by 7.5%, compared with an increase of 20% in those receiving standard treatment alone. Patients taking European barberry also had improvements in body weight, systolic and diastolic blood pressure, and total cholesterol when compared with standard treatment alone (98575).
• Gingivitis. It is unclear if brushing the teeth with a gel containing European barberry is beneficial for gingivitis. Details: Preliminary clinical research in males 11-12 years of age shows that brushing with a European barberry extract gel containing berberine 1%, three times daily for 3 weeks, reduces gingival inflammation when compared with placebo. This effect was similar to that seen with a commercial antiplaque toothpaste (Colgate) (33695).
• Hyperlipidemia. It is unclear if oral European barberry is beneficial for hyperlipidemia. Details: Meta-analyses of five small clinical trials shows that taking European barberry decreases total cholesterol by 24 mg/dL, low-density lipoprotein (LDL) cholesterol by 14 mg/dL, and triglycerides by 29 mg/dL, without significantly affecting high-density lipoprotein (HDL) cholesterol, when compared with a control intervention (102055,105756). However, because the studies included in these analyses enrolled patients with diabetes, metabolic syndrome, or nonalcoholic fatty liver disease (NAFLD), the effects of European barberry on lipid levels in patients with hyperlipidemia are unclear.
• Opioid withdrawal. It is unclear if oral European barberry is beneficial for opioid withdrawal. Details: Clinical research in patients using methadone during opioid withdrawal shows that taking European barberry root extract 500 mg twice daily for 4 weeks reduces overall symptoms of withdrawal by a large amount, but does not improve depression, anxiety, stress, or sleep quality, when compared with placebo (108156). More evidence is needed to rate European barberry for these uses.

• Urinary tract infections (UTIs). Clinical research does not support the use of oral uva ursi for treatment of UTIs. For prevention of UTIs, oral uva ursi has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A large clinical study in females with uncomplicated UTI shows that taking uva ursi tablets providing 210 mg arbutin orally three times daily for 5 days is less effective than a single dose of fosfomycin 3 grams for reducing UTI symptom burden and the number of rescue antibiotic courses. Rescue antibiotics were needed in 44% of patients receiving uva ursi, compared with 23% of those receiving fosfomycin. On day 4, the percentage of patients with symptom resolution was 49% with uva ursi, compared to 65% with fosfomycin. Pyelonephritis occurred in 8 patients on uva ursi and 2 patients on fosfomycin (109535). Also, a large clinical study in females experiencing symptoms of a UTI shows that taking uva ursi extract 1200 mg three times daily for 3-5 days does not improve symptoms or reduce the need for antibiotics when compared with placebo (101815). Uva ursi has also been evaluated for the prevention of UTIs. One small clinical study in females with recurrent UTI shows that taking a specific combination product containing uva ursi and dandelion (UVA-E, Medic Herb AB) 3 tablets three times daily for one month reduces the recurrence rate of UTIs when compared with placebo (1932). It is not clear if this effect is due to uva ursi, dandelion, or the combination.

General ...Orally, burdock is well tolerated when consumed as a food. Although a thorough evaluation of safety outcomes is lacking, there has been long-standing historical use of burdock with few noted adverse effects.
Serious Adverse Effects (Rare):
All ROAs: Allergic reactions, including contact dermatitis and anaphylaxis.

Dermatologic ...Contact dermatitis has been reported secondary to burdock, especially after prolonged use of the root oil (37422). There are cases of allergic dermatitis secondary to using burdock plasters. Two males and a 14 year-old female developed erythematous and vesicular, pruritic, and exudative reactions in areas corresponding to the application of burdock root plasters (12667). Reactions occurred up to 7 days after initial use. Patch testing was positive for burdock sensitivity in all three patients and was nonreactive in matched controls.

Hematologic ...In one case report, a 38-year-old female developed immune-mediated thrombocytopenia after consuming a "cleansing" tea containing unknown amounts of burdock and yellow dock. The patient presented with bruising, mild weakness, and fatigue, which started 2-3 days after consuming the tea, and was found to have a platelet count of 5,000 per mcL. Symptoms resolved after platelet transfusion and treatment with oral dexamethasone (108971). It is unclear if these effects were caused by burdock, yellow dock, the combination, or other contributing factors.

Hepatic ...A case of idiosyncratic drug-induced liver disease (DILI) is reported in a 36-year-old female who presented with abdominal pain after 1 month of taking an herbal liver detox tea containing burdock and other ingredients. Remarkable laboratory values included elevated liver enzymes, alkaline phosphatase, and total bilirubin. The patient received a loading dose of N-acetylcysteine and was hospitalized for 12 days (112178). However, it is unclear if the adverse effect was due to burdock, other ingredients, or the combination.

Immunologic ...There is one case of anaphylactic shock secondary to eating boiled burdock. One hour after eating boiled burdock the patient presented with redness over the entire body and dyspnea. He was found to have low blood pressure and was treated with subcutaneous epinephrine 1 mg and intravenous lactated ringer's solution containing hydrocortisone 100 mg and dexamethasone 8 mg. The cause of anaphylactic shock was attributed to allergenicity to burdock based on positive skin prick test results. Previously, the patient had experienced urticaria after eating boiled burdock (12660).

Neurologic/CNS ...Anticholinergic reactions including dry mouth, dizziness, blurred vision, weakness, dilated pupils, inability to urinate, and bradycardia have been reported following the consumption of burdock products (12662,37421,37431,37434,37435). However, these anticholinergic reactions are believed result from contamination of burdock with belladonna alkaloids. Burdock itself does not contain atropine or other constituents that would be responsible for these reactions.

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 diuretic, 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).

Gastrointestinal ...Orally, uva ursi may cause nausea, vomiting, diarrhea, and stomach upset (92148). It can also irritate the gastrointestinal tract (19).

Genitourinary ...Orally, uva ursi may cause the urine to be greenish-brown. It may also cause irritation and inflammation of the urinary tract mucous membranes (18).

Hepatic ...Uva ursi may be hepatotoxic. Theoretically, chronic use, especially in children, can cause liver impairment due its hydroquinone and high tannin content (4,18).

Neurologic/CNS ...Orally, around 20 grams of uva ursi is reported to supply up to one gram of hydroquinone, which can theoretically cause convulsions and delirium (4).

Ocular/Otic ...Orally, uva ursi may potentially cause retinal toxicity due to its hydroquinone content, which reduces melanin synthesis. A 56-year-old female developed bilateral bull's-eye maculopathy, paracentral scotomas, and retinal thinning after 3 years of uva ursi tea ingestion (16900).
Taking around 20 grams of uva ursi orally is reported to supply up to one gram of hydroquinone, which can theoretically cause tinnitus (4).

Pulmonary/Respiratory ...Orally, around 20 grams of uva ursi is reported to supply up to one gram of hydroquinone, which can theoretically cause shortness of breath and cyanosis (4).

General ...Orally, yellow dock seems to be well tolerated when properly prepared and consumed in food amounts. Consuming raw yellow dock leaves or rhizomes may be unsafe.
Serious Adverse Effects (Rare):
Orally: Raw leaves or rhizomes can cause hypocalcemia, kidney stones, and vomiting.

Cardiovascular ...Orally, yellow dock has been linked to ventricular fibrillation and death after ingestion of 500 grams (17). Oxalic acid, a constituent of yellow dock, reacts with calcium in plasma, forming insoluble calcium oxalate, which can cause hypocalcemia; the crystals may precipitate in the blood vessels and heart (12). Older or uncooked leaves should be avoided (6).

Dermatologic ...Orally, yellow dock can cause dermatitis when consumed in large amounts (4). Topically, contact with the plant may cause dermatitis in people sensitive to yellow dock (6).

Gastrointestinal ...Orally, vomiting may occur after ingestion of fresh rhizome (18). Consuming excessive amounts can cause diarrhea and nausea (6). Excessive use can also cause abdominal cramps and intestinal atrophy (4). There is one report of a death, preceded by vomiting and diarrhea, after ingestion of 500 grams of yellow dock (17). Older or uncooked leaves should be avoided (6).

Genitourinary ...Orally, yellow dock can cause polyuria when consumed in large amounts (6).

Hematologic ...Orally, in one case report, a 38-year-old female developed immune-mediated thrombocytopenia after consuming a "cleansing" tea containing unknown amounts of yellow dock and burdock. The patient presented with bruising, mild weakness, and fatigue, which started 2-3 days after consuming the tea, and was found to have a platelet count of 5,000 per mcL. Symptoms resolved after platelet transfusion and treatment with oral dexamethasone (108971). It is unclear if these effects were caused by yellow dock, burdock, the combination, or other contributing factors.

Hepatic ...Orally, yellow dock has been linked to liver failure and death after ingestion of 500 grams (17). Oxalic acid, a constituent of yellow dock, reacts with calcium in plasma, forming insoluble calcium oxalate, which can cause hypocalcemia; the crystals may precipitate in the liver (12). Older or uncooked leaves should be avoided (6).

Neurologic/CNS ...Orally, yellow dock has been linked to coma and death after ingestion of 500 grams (17). Older or uncooked leaves should be avoided (6).

Pulmonary/Respiratory ...Orally, yellow dock has been linked to respiratory depression and death after ingestion of 500 grams (17). Oxalic acid, a constituent of yellow dock, reacts with calcium in plasma, forming insoluble calcium oxalate, which can cause hypocalcemia; the crystals may precipitate in the lungs (12). Older or uncooked leaves should be avoided (6).

Renal ...Orally, yellow dock can cause polyuria when consumed in large amounts (6). There is one report of a death, preceded by kidney failure, after ingestion of 500 grams (17). Oxalic acid, a constituent of yellow dock, reacts with calcium in plasma, forming insoluble calcium oxalate, which can cause hypocalcemia; the crystals may precipitate in the kidneys. Individuals with a history of kidney stones should use yellow dock cautiously (12). Older or uncooked leaves should be avoided (6).

Other ...Orally, yellow dock can cause hypokalemia when taken in large amounts (4). There is one report of a death, preceded by severe metabolic acidosis, after ingestion of 500 grams of yellow dock (17). Oxalic acid, a constituent of yellow dock, reacts with calcium in plasma, forming insoluble calcium oxalate, which can cause hypocalcemia; the crystals may precipitate in the kidneys, blood vessels, heart, lungs, and liver (12). Older or uncooked leaves should be avoided (6).
