HelloPharmacist Scorecard of LG-W by Pure Herbs
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Low disclosure
Pure Herbs LG-W is a liquid containing 4 active ingredients: burdock root extract, calendula flower extract, yellow dock root extract, and Chinese rhubarb root extract, plus a proprietary blend that draws from these same components. The product contains no other inactive ingredients listed.
Does it work?
Moderate evidence
The effectiveness data we hold doesn't establish clear benefits for any condition this product may be marketed for. Burdock, calendula, and yellow dock all carry ratings of insufficient reliable evidence across the uses listed—acne, skin aging, eczema, burns, and others.
Chinese rhubarb root extract shows possibly effective ratings for pancreatitis and menopausal symptoms, but evidence remains limited. If you're considering this product for a specific health concern, talk with your doctor or pharmacist about what the research actually supports.
How safe is it?
Well-documented data
Burdock root extract is likely safe as a food and for short-term use in healthy adults, though human safety data are limited. It's well tolerated orally, though rare allergic reactions—including contact dermatitis and anaphylaxis—have occurred.
A case of liver injury was reported in someone taking a detox tea with burdock and other ingredients, though it's unclear if burdock was the cause. Calendula is generally well tolerated on skin but can cause allergic reactions, especially in people sensitive to ragweed or related plants.
Yellow dock acts as a laxative and contains oxalates; it should be used short-term and with care. Chronic or large-dose use can cause cramping, diarrhea, and—rarely—serious effects like low blood calcium and kidney stones from its oxalic acid content.
Chinese rhubarb root similarly works as a stimulant laxative and is well tolerated in food and medicinal amounts, but chronic overuse can deplete potassium and electrolytes, damage kidneys, and cause liver injury. Regarding pregnancy and breastfeeding: burdock and yellow dock should be avoided at medicinal doses during pregnancy due to lack of safety data and possible uterine effects; calendula is likely unsafe in pregnancy; and rhubarb is possibly unsafe in both pregnancy and lactation.
Yellow dock and rhubarb's laxative compounds may pass into breast milk. Talk with your doctor or pharmacist before using this product if you're pregnant or nursing.
Meds to double-check
Major interaction found
Check with your own doctor or pharmacist before using this product if you take any diuretics (water pills), digoxin or other heart medications, warfarin or other blood thinners, corticosteroids, cyclosporine, stimulant laxatives, or any drugs that can harm the kidneys or liver. The two rhubarb and yellow dock extracts in this formula carry the highest-severity interactions with these drug classes.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This product combines four herbal extracts with limited evidence of effectiveness and several documented medication interactions—most notably with diuretics, heart drugs, blood thinners, and potassium-affecting medications. If you take any prescription drugs, especially those for heart, kidney, liver, or blood conditions, check with your own doctor or pharmacist before starting.
Pregnant or nursing women should avoid it. It's generally well tolerated by mouth, but long-term use isn't recommended due to potential laxative effects and electrolyte loss.

LG-W by Pure Herbs Drug Interactions
HelloPharmacist Interaction Report
Pure Herbs LG-W contains four active ingredients, and three of them—yellow dock root extract, Chinese rhubarb root extract, and burdock root extract—carry documented interactions with medications.
The most serious concern is yellow dock's Major-severity interaction with diuretic drugs; yellow dock can cause potassium loss (hypokalemia) that compounds what diuretics already do, potentially leading to dangerously low potassium levels.
Read the full breakdown — every affected drug type, severity by severity
Chinese rhubarb root extract has the broadest interaction profile. It carries Major or Moderate interactions with nephrotoxic drugs (kidney-damaging medications), hepatotoxic drugs (liver-damaging ones), corticosteroids, diuretics, stimulant laxatives, warfarin (a blood thinner), digoxin (a heart medication), and cyclosporine (an immunosuppressant).
Most of these stem from rhubarb's laxative effect and its potential to deplete potassium. Yellow dock shares similar concerns: Major interactions with digoxin and Moderate interactions with warfarin.
Burdock root extract carries a Moderate interaction with blood thinners (anticoagulants) and antiplatelet drugs—it may increase bleeding risk, though this hasn't been reported in humans.
Calendula flower extract has only a Minor interaction with CNS depressants (sedatives, sleep aids, and similar medications), and that risk appears theoretical and unlikely based on over 30 years of human use without reports of sedation.
Altogether, these interactions span 904 individual medications. Before taking this product, check your exact prescriptions—especially diuretics, heart medications, blood thinners, steroids, kidney or liver medications, and immunosuppressants—with your own doctor or pharmacist.

For each ingredient in LG-W with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Chinese Rhubarb Root Extract
Corticosteroids
Theoretically, frequent and high doses of rhubarb might increase the risk of hypokalemia when taken with corticosteroids.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might compound corticosteroid-induced potassium loss.
Cyclosporine (Neoral, Sandimmune)
Theoretically, taking rhubarb with cyclosporine might reduce cyclosporine levels.
Animal research shows that co-administration of rhubarb decoction 0.25 or 1 gram/kg with cyclosporine 2.5 mg/kg, decreases cyclosporine maximum plasma concentration and overall exposure levels when compared with taking cyclosporine alone. The authors theorize that rhubarb might reduce cyclosporine bioavailability by inducing of P-glycoprotein and/or cytochrome P450 3A4. However, since rhubarb was administered as a single oral dose and enzyme induction usually occurs after multiple doses, it is possible that cyclosporine absorption was actually reduced via rhubarb's stimulant laxative effects. Also, the composition of the rhubarb decoction was not described.
Digoxin (Lanoxin)
Theoretically, overuse of rhubarb might increase the risk of adverse effects when taken with digoxin.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might cause potassium depletion, increasing the risk of digoxin toxicity.
Diuretic Drugs
Theoretically, frequent and high doses of rhubarb might increase the risk of hypokalemia.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might cause potassium depletion and compound diuretic-induced potassium loss.
Hepatotoxic Drugs
Theoretically, concomitant use of rhubarb with potentially hepatotoxic drugs might increase the risk of developing liver damage.
Some animal research suggests that anthraquinones in rhubarb might have hepatotoxic effects. Also, rhubarb use has been linked to at least 24 cases of liver injury, although details on the dose of rhubarb and duration of use in these cases is unclear.
Nephrotoxic Drugs
Theoretically, long-term use of anthraquinones from rhubarb might increase the risk of nephrotoxicity when used with nephrotoxic drugs.
The anthraquinone constituents of rhubarb have been shown to induce nephrotoxicity in animal research. Additionally, in a case report, a 23-year old female presented with kidney failure after taking 6 tablets of a proprietary slimming agent (found to contain the anthraquinones emodin and aloe-emodin from rhubarb) daily for 6 weeks and then adding diclofenac 25 mg 4 times daily for 2 days. The authors postulate that the anthraquinone constituents of rhubarb contributed to the renal dysfunction, and the addition of diclofenac, a nephrotoxic drug, led to renal failure. Until more is known, advise patients to avoid taking rhubarb if they are taking other potentially nephrotoxic drugs.
Stimulant Laxatives
Theoretically, rhubarb might increase the risk for fluid and electrolyte loss when taken with other stimulant laxatives.
Rhubarb has stimulant laxative effects. Concomitant use with stimulant laxatives might compound fluid and electrolyte loss.
Warfarin (Coumadin)
Theoretically, excessive use of rhubarb might increase the risk of bleeding when taken with warfarin.
Rhubarb has stimulant laxative effects and can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of rhubarb.
Calendula flower extract
Cns Depressants
Theoretically, calendula might have additive effects when used with CNS depressants, although this appears to be unlikely.
Although some animal research has suggested that a saponoside constituent in calendula may have sedative effects, calendula has been used for over 30 years without reports of sedation in humans.
Burdock Root Extract
Anticoagulant/Antiplatelet Drugs
Theoretically, taking burdock with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
In vitro research shows that lignans from burdock reduce rabbit platelet aggregation by inhibiting platelet activating factor. This interaction has not been reported in humans.
Yellow Dock root extract
Digoxin (Lanoxin)
Theoretically, yellow dock might increase the risk of digoxin toxicity when used long-term or in large amount.
When yellow dock is used chronically or in large amounts, hypokalemia may occur. This might increase the toxic effects of digoxin.
Diuretic Drugs
Theoretically, yellow dock might increase the risk of hypokalemia when taken with diuretics.
When yellow dock is used chronically or in large amounts, hypokalemia may occur, and overuse of yellow dock might compound diuretic-induced potassium loss.
Warfarin (Coumadin)
Theoretically, the laxative effects of yellow dock might increase the effects of warfarin, including the risk of bleeding.
The anthraquinones in yellow dock have a mild stimulant laxative effect. Consuming excessive amounts can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding.
