Below is general information about the interactions of the known ingredients contained in the product Flor-Essence. 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, blessed thistle might decrease the effectiveness of antacids.
Details
There are reports that blessed thistle increases stomach acid (19).
|
Theoretically, blessed thistle might decrease the effectiveness of H2-blockers.
Details
There are reports that blessed thistle increases stomach acid (19).
|
Theoretically, blessed thistle might decrease the effectiveness of PPIs.
Details
There are reports that blessed thistle increases stomach acid (19).
|
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. |
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, slippery elm may slow the absorption and reduce serum levels of oral drugs.
Details
Slippery elm inner bark contains mucilage, which may interfere with the absorption of orally administered drugs (19).
|
Theoretically, sorrel might cause additive effects and side effects when used with anticoagulant or antiplatelet drugs.
Details
In vitro, sorrel has been shown to inhibit platelet aggregation (103607). However, this effect has not been reported in humans.
|
Sorrel might reduce the effectiveness of fexofenadine by reducing its absorption from the gut.
Details
In vitro research shows that an ethanol extract of sorrel inhibits organic anion-transporting polypeptide 1A2 (OATP1A2), which transports fexofenadine from the intestine into cells. In rats, concomitant administration of sorrel extract with fexofenadine reduces oral absorption of fexofenadine and the area under the plasma concentration-time curve (AUC) (103606).
|
Sorrel might reduce the effectiveness of OATP substrates by reducing their absorption from the gut.
Details
In vitro research shows that sorrel inhibits OATP1A2 (103606). Theoretically it may inhibit other OATPs. The OATPs are expressed in the small intestine and liver and transport drugs into cells. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.
|
Watercress might reduce the metabolism of chlorzoxazone and increase its effects and side effects. Clinical research in healthy volunteers shows that a single ingestion of watercress 50 grams increases the chlorzoxazone plasma concentration-time curve by about 56% and increases its half-life by about 53% (4018).
|
Watercress is thought to have diuretic properties (18). Theoretically, due to these potential diuretic effects, watercress might reduce excretion and increase levels of lithium.
|
Watercress contains vitamin K. Consuming large amounts of watercress might antagonize the anticoagulant effects of warfarin (11285).

Below is general information about the adverse effects of the known ingredients contained in the product Flor-Essence. 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, 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 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, slippery elm seems to be well tolerated. A thorough evaluation of safety outcomes with topical use of slippery elm has not been conducted.
Dermatologic ...Topically, slippery elm extracts can cause contact dermatitis. The pollen is an allergen (6). Contact dermatitis and urticaria have been reported after exposure to slippery elm or an oleoresin contained in the slippery elm bark (75131).
General
...Orally, sorrel seems to be generally well tolerated, based on limited data, mainly from studies with combination products.
Serious Adverse Effects (Rare):
Orally: Gastrointestinal irritation, kidney damage, liver necrosis.
Dermatologic ...Orally, sorrel, when used in combination with other herbs, has been reported to cause allergic skin reactions (374,379).
Gastrointestinal ...Orally, sorrel, when used in combination with other herbs, has been reported to cause gastrointestinal side effects including nausea and an unpleasant aftertaste (374,379,37419).
Hepatic ...Extensive liver necrosis with hepatic failure has been reported with the ingestion of large amounts of sorrel; this was likely due to its oxalate content (75138).
Pulmonary/Respiratory ...Environmental exposure to sorrel pollen may trigger allergic rhinitis or bronchial asthma in hypersensitive individuals, and allergic cross-sensitivity may occur in up to 19% of people who are allergic to weed pollen (75141).
Renal ...Sorrel contains oxalates; irolithiasis and nephrosis may be caused by the systemic absorption of oxalates and may result in kidney damage (71314). A case of acute tubulointerstitial nephritis (TIN) has been reported in a 12-year-old who consumed an unknown amount of wild sorrel. The patient presented with polyuria, hypophosphatemia, proteinuria, glucosuria, and hyperoxaluria. Recovery occurred after oral rehydration and electrolyte replacement. The TIN was likely due to formation of calcium oxalate crystals in the kidneys (94019).
General
...Orally, watercress is well-tolerated when consumed in food amounts.
There is limited reliable information available about the adverse effects of watercress when used in medicinal amounts. When excessive doses are used, watercress can cause gastrointestinal irritation (85599). Consuming raw watercress has been associated with the development of fascioliasis, a parasitic fluke disease of the liver (85575,85574,85573,85567,85564,85582,85563,85562,85580,85561,85560)(85554,85558,85596,85579,85571,85569,85583,85586,85584,85588)(85585,85590,85592,85591).
Topically, watercress can cause contact dermatitis (85594,85587).
Dermatologic ...Topically, watercress can cause contact dermatitis, resulting in hives, rash, itching, or swollen skin (85594,85587).
Gastrointestinal ...Orally, large quantities of watercress may cause gastrointestinal irritation (85599).
Hepatic ...Raw, wild watercress can be contaminated with parasitic flukes which, when ingested, cause the liver disease fascioliasis. Symptoms include abdominal pain, fever, vomiting, diarrhea, urticaria, eosinophilia, and hepatomegaly (85575,85574,85573,85567,85564,85582,85563,85562,85580,85561)(85560,85554,85558,85596,85579,85571,85569,85583,85586,85584)(85588,85585,85590,85592,85591). Clinical research shows that taking a standardized extract of watercress orally 750 mg/kg daily for 5 weeks is not associated with increases in liver function enzymes (109666).
Renal ...Orally, excessive or prolonged use of watercress may theoretically cause kidney damage (85598). However, in overweight adults with physical disabilities, taking a watercress extract 750 mg/kg daily for 5 weeks does not cause any change in levels of creatinine or urea (109666).
