Below is general information about the interactions of the known ingredients contained in the product Lymphatic & Blood Cleanse 285 mg. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, taking burdock with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
Details
In vitro research shows that lignans from burdock reduce rabbit platelet aggregation by inhibiting platelet activating factor (12619). This interaction has not been reported in humans. |
Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
Details
In vitro research suggests that dandelion root inhibits platelet aggregation (18291).
|
Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Details
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion (13474,90926). Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion (46960).
|
Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Details
Laboratory research suggests that dandelion might inhibit CYP1A2 (12734). So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.
|
Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
Details
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme (12734).
|
Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Details
Animal research suggests that dandelion has diuretic properties (13475). As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.
|
Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Details
Dandelion contains significant amounts of potassium (13465).
|
Theoretically, dandelion might lower fluoroquinolone levels.
Details
Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73% (13477). However, this effect has not been reported in humans.
|
Although some laboratory research suggests that red clover may have anticoagulant and antiplatelet activity, clinical research has not shown this effect.
Details
In vitro research suggests that genistein in red clover has antiplatelet effects, and historically, red clover was thought to have anticoagulant effects due to its coumarin content. However, some experts state that this is unlikely as most natural coumarins have not been shown to have anticoagulant effects, and their content in red clover is low (17091,19557,19558,19559). Additionally, some clinical research in postmenopausal patients found no effect on coagulation or prothrombin time with the use of red clover flowering tops 378 mg daily for 12 months or red clover isoflavone (Rimostil) 50 mg daily for 2 years (17091,91524).
|
Theoretically, soy might reduce the clearance of caffeine; however, a small clinical study found no effect.
Details
Red clover contains genistein. Taking genistein 1 gram daily for 14 days seems to inhibit caffeine clearance and metabolism in healthy females (23582). However, this effect does not seem to occur with the lower amounts of genistein found in red clover. A clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of caffeine (105693).
|
Theoretically, red clover might increase levels of drugs metabolized by CYP1A2; however, a small clinical study found no effect.
Details
In vitro evidence shows that red clover inhibits CYP1A2 (12479). However, a clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of caffeine, a CYP1A2 probe substrate (105693).
|
Theoretically, red clover might increase the levels and clinical effects of drugs metabolized by CYP2C19.
Details
In vitro evidence suggests that red clover weakly inhibits CYP2C19 (12479). This interaction has not been reported in humans.
|
Theoretically, red clover might increase levels of drugs metabolized by CYP2C9; however, a small clinical study found no effect.
Details
In vitro evidence suggests that red clover might inhibit CYP2C9 (12479). However, a clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of tolbutamide, a CYP2C9 probe substrate (105693).
|
Theoretically, red clover might increase levels of drugs metabolized by CYP3A4; however, a small clinical study found no effect.
Details
In vitro evidence shows that red clover might inhibit CYP3A4 isoenzymes (6450,12479). However, a clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of alprazolam, a CYP3A4 probe substrate (105693).
|
Theoretically, concomitant use of large amounts of red clover might interfere with estrogen therapy.
Details
|
Theoretically, red clover might increase the risk of methotrexate toxicity.
Details
In a case report, a 52-year-old female receiving weekly methotrexate injections for psoriasis developed symptoms of methotrexate toxicity, including severe vomiting and epigastric pain, after three days of taking red clover 430 mg daily. Toxicity resolved after red clover was discontinued. However, no liver function tests or methotrexate levels were reported (91522).
|
Theoretically, the phytoestrogens in red clover might interfere with tamoxifen.
Details
In vitro and animal research suggests that genistein, a constituent of red clover, might antagonize the antitumor effects of tamoxifen (8192). However, there is some evidence from an animal study that red clover does not reduce the efficacy of tamoxifen (102901). Until more is known, tell patients taking tamoxifen to avoid red clover.
|
Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Details
|
Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Details
|
Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Details
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium (76402). The dose of lithium might need to be decreased.
|
There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Details
Stinging nettle contains a significant amount of vitamin K (19). When taken in large quantities, this might interfere with the activity of warfarin.
|
Theoretically, yellow dock might increase the risk of digoxin toxicity when used long-term or in large amount.
Details
|
Theoretically, yellow dock might increase the risk of hypokalemia when taken with diuretics.
Details
|
Theoretically, the laxative effects of yellow dock might increase the effects of warfarin, including the risk of bleeding.

Below is general information about the adverse effects of the known ingredients contained in the product Lymphatic & Blood Cleanse 285 mg. 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, 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.
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
...Orally and topically, red clover seems to be well tolerated.
Most Common Adverse Effects:
Orally: Myalgia, nausea, and vaginal spotting.
Dermatologic ...Orally, a specific red clover isoflavone product (Promensil) has been associated with mild cases of psoriasis and thrush, although a direct causal link has not been established (9552).
Gastrointestinal ...Orally, red clover has been reported to cause nausea (8194).
Genitourinary ...In human research, 80 mg, but not 40 mg, of a specific red clover isoflavone product (Promensil) increased the duration of menstrual cycles in patients with mastalgia (9552). Red clover has also been reported to cause vaginal spotting (8194).
Hematologic ...In one case report, a 53-year-old female had a spontaneous subarachnoid hemorrhage associated with the use of an herbal supplement containing red clover, dong quai, and eleuthero. It is not clear if this was due to red clover, another ingredient, the combination of ingredients, or other factors (70419). In another 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 red clover 250 mg, wild yam 276 mg, dong quai 100 mg, and black cohosh 250 mg (13155). It is unclear if red clover contributed to this event.
Musculoskeletal ...Orally, red clover has been reported to cause myalgia (8194).
Neurologic/CNS ...Orally, a specific red clover isoflavone product (Medoflavon) has been associated with headache, although with a similar frequency to placebo (19545).
Oncologic ...Due to potential estrogenic effects of red clover isoflavones, there has been some concern that red clover might increase the risk of estrogen-sensitive cancers such as breast cancer or uterine cancer. A meta-analysis of 8 clinical trials suggests that increased intake of red clover- and soy-derived isoflavones may modestly increase mammographic breast density in premenopausal, but not postmenopausal, adults when compared with placebo. However, in a sub-group analysis assessing only isolated red clover isoflavones, there was no change in breast density (70428). Furthermore, a 2015 review by the European Food Safety Authority (EFSA) reported no increase in risk of breast cancer in females taking isoflavone-containing supplements (91725). Similarly, no effect was found on endometrial thickness and histopathological changes in the uterus after up to 36 months of supplementation with 40-120 mg daily of isoflavones from red clover extract (91725).
General
...Orally, stinging nettle seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Constipation, diarrhea.
Topically: Contact with the raw plant causes itching, rash, and stinging.
Dermatologic ...Topically, fresh stinging nettle leaves and stalk can cause localized rash, itching, and stinging (12490,76399,76412,76414,76417,76428,76448,96746). Usually, short exposure to stinging nettle results in a transient urticarial reaction and a stinging sensation which may persist for more than 12 hours (76399,76414,76417,96746). In one report, a patient placed a fresh stinging nettle leaf on the tongue to suck out the sap of the leaf. Severe tongue edema, pain, and urticaria developed within 5 minutes. Symptoms continued for several hours after the leaf was removed (15197). In another case report, a young couple intoxicated with methamphetamine fell and laid in a stinging nettle bush for 20 minutes, after which urticaria and pain continued for 2-3 weeks, and a heightened sensitivity to cold persisted for several months (96746).
Endocrine
...A case of gynecomastia has been reported for a 33-year-old male who consumed stinging nettle tea 2 cups daily for one month prior to symptom onset.
The condition subsided one month after discontinuing stinging nettle tea (76410).
There have been two cases of galactorrhea associated with the consumption of stinging nettle for one month (76410,108902). In one case, a 33-year-old female consuming stinging nettle tea showed high levels of estradiol and low levels of follicle stimulating hormone (FSH) and luteinizing hormone (LH). The levels of these hormones normalized 6 weeks after discontinuing stinging nettle tea (76410). In the other case report describing a 30-year-old female self-treating with stinging nettle 500 mg daily, hormone levels were not reported; however, a mammogram showed scattered areas of fibroglandular density and benign-appearing calcifications. This patient had complete resolution of symptoms 1 week after discontinuation of stinging nettle (108902).
Gastrointestinal ...Orally, stinging nettle root can cause gastrointestinal complaints, including diarrhea and constipation (1,7,11230). Stinging nettle above ground parts may cause mild gastrointestinal discomfort when taken on an empty stomach (7035). Stinging nettle juice may cause diarrhea (1). One patient taking a combination product containing stinging nettle root extract and pygeum bark extract (Prostatonin, Pharmaton) experienced continual gastrointestinal pain and hyperperistalsis. It is not clear if this effect was due to stinging nettle or pygeum (70230).
Genitourinary ...There is a case report of decreased ejaculatory volume associated with an herbal blend product containing stinging nettle root extract, saw palmetto extract, pumpkin seed oil extract, lemon bioflavonoid extract, and beta-carotene (5093). It is unclear if this was due to stinging nettle, other ingredients, or the combination.
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 stinging nettle 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 the stinging nettle, other ingredients, or the combination.
Other ...Orally, stinging nettle root can cause sweating (1,7).
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).
