What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,887 mg) without saying how much of each component you get.

Pure Herbs FVE-W is a liquid supplement with four active ingredients. Chickweed aerial parts extract is included for general wellness, though evidence for its effectiveness is limited.

Dog rose fruit extract (also called rose hip) provides vitamin C and other plant compounds; it's traditionally used for joint comfort and cholesterol support. Goldenseal root extract contains alkaloids including berberine and is used in herbal practice for immune and digestive support.

Myrrh resin extract, a traditional botanical, is included for general wellness purposes. The product contains no other inactive ingredients.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: maintain a healthy immune system.
  • We looked for evidence on: Common cold, Influenza, Respiratory tract infections, Cough, Immune support, Immunomodulation — and 1 related terms.
  • The closest evidence on file: Myrrh is rated "Insufficient Reliable Evidence To Rate" for Common cold (Natural Medicines).
  • Also on file: Myrrh is rated "Insufficient Reliable Evidence To Rate" for Cough.
  • Also on file: Rose Hip is rated "Insufficient Reliable Evidence To Rate" for Common cold, Influenza.

The evidence for what this product can actually do is sparse. Dog rose fruit extract is possibly effective for postoperative pain and osteoarthritis, but data are limited.

Chickweed, goldenseal, and myrrh all lack reliable evidence for the conditions they're traditionally used for—the data we hold rates them as having insufficient evidence. That doesn't mean they don't work; it means the research hasn't established it yet.

The evidence, ingredient by ingredient Chickweed Rose Hip Goldenseal Myrrh

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Dog rose fruit extract and myrrh are generally well tolerated at food doses, but safety data on supplement-strength doses is limited; use caution and check with your doctor or pharmacist about whether a higher-dose supplement is right for you. Goldenseal is typically used short-term by healthy adults, though human safety research is sparse.

The most common side effects reported across these ingredients are digestive—flatulence, loose stools, diarrhea, nausea, abdominal cramping, and constipation. Topically, chickweed and myrrh have rarely caused contact dermatitis.

During pregnancy, avoid this product. Goldenseal and myrrh are rated likely unsafe—goldenseal's berberine may harm the fetus and trigger contractions, and myrrh has traditionally been thought to stimulate the uterus.

Chickweed is rated likely safe in pregnancy, but the safety data are insufficient overall for the combination product. Avoid this product while breastfeeding; goldenseal's berberine may pass to your infant and cause harm, and myrrh safety during breastfeeding is unknown.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 4 matched ingredients can interact with medications — Myrrh, Rose Hip, Goldenseal.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; cancer treatments; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 1,284 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you take this product, check your medications against these drug types: any liver-metabolized medications (because of goldenseal's enzyme inhibition), blood thinners and antiplatelet drugs (dog rose and goldenseal), estrogen-containing hormones like birth control or hormone therapy (dog rose), diabetes medications (goldenseal and myrrh), blood pressure drugs (goldenseal), CNS depressants like sedatives or anti-anxiety medications (goldenseal), lithium (dog rose), and chemotherapy drugs (dog rose). If you take any of these, run your specific medications through the interaction checker on this page before you start.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This liquid herbal blend works best as a short-term supplement for people with no major medical conditions and no medications that interact with its ingredients. If you take any prescription drugs—especially blood thinners, diabetes medicines, blood pressure drugs, birth control, or chemotherapy—talk with your doctor or pharmacist before you start, because the ingredient interactions are extensive.

Each ingredient & the kinds of drugs it affects

For each ingredient in FVE-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.

Goldenseal Root Extract16 drug types · 1,237 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, goldenseal might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Goldenseal contains berberine. In vitro and animal research shows that berberine can inhibit platelet aggregation. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, goldenseal might increase the risk of hypoglycemia when used with antidiabetes drugs.
Goldenseal contains berberine. Clinical research shows that berberine can lower blood glucose levels. However, this effect has not been reported with goldenseal.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, goldenseal might increase the risk of hypotension when taken with antihypertensive drugs.
Goldenseal contains berberine. Animal research shows that berberine can have hypotensive effects. Also, an analysis of clinical research shows that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone. However, this effect has not been reported with goldenseal.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, goldenseal might increase the sedative effects of CNS depressants.
Goldenseal contains berberine. Animal research shows that berberine can have sedative effects. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, goldenseal might increase serum levels of drugs metabolized by CYP2C9.
In vitro research shows that goldenseal root extract can modestly inhibit CYP2C9. This effect may be due to its alkaloid constituents, hydrastine and berberine. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Goldenseal might increase serum levels of drugs metabolized by CYP2D6.
Clinical and in vitro research shows that goldenseal can significantly inhibit CYP2D6 enzymes, potentially increasing levels of drugs metabolized by CYP2D6.

Likelihood Probable Evidence B
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, goldenseal might increase serum levels of drugs metabolized by CYP2E1.
In vitro research shows that goldenseal root extract can inhibit the activity of CYP2E1. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Goldenseal might increase serum levels of drugs metabolized by CYP3A4.
Most clinical and in vitro research shows that goldenseal inhibits CYP3A4 enzyme activity and increases serum levels of CYP3A4 substrates, such as midazolam. However, in one small clinical study, goldenseal did not affect the levels of indinavir, a CYP3A4 substrate, in healthy volunteers. This is likely due to the fact that indinavir has a high oral bioavailability, making it an inadequate probe for CYP3A4 interactions and/or that it is primarily metabolized by hepatic CYP3A, while goldenseal has more potential to inhibit intestinal CYP3A enzyme activity. Both goldenseal extract and its isolated constituents berberine and hydrastine inhibit CYP3A, with hydrastine possibly having more inhibitory potential than berberine.

Likelihood Possible Evidence B
Dextromethorphan (Robitussin Dm, Others)

Theoretically, goldenseal might increase serum levels of dextromethorphan.
Goldenseal contains berberine. A small clinical study shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Goldenseal might increase serum levels of digoxin, although this effect is unlikely to be clinically significant.
Clinical research shows that goldenseal modestly increases digoxin peak levels by about 14% in healthy volunteers. However, goldenseal does not seem to affect other pharmacokinetic parameters such as area under the curve (AUC). This suggests that goldenseal does not cause a clinically significant interaction with digoxin. Digoxin is a P-glycoprotein substrate. Some evidence suggests that goldenseal constituents might affect P-glycoprotein; however, it is unclear whether these constituents inhibit or induce P-glycoprotein.

Likelihood Probable Evidence B
Losartan (Cozaar)

Theoretically, goldenseal might decrease the conversion of losartan to its active form.
Goldenseal contains berberine. A small clinical study shows that berberine inhibits cytochrome P450 2C9 (CYP2C9) activity and reduces the metabolism of losartan. However, this effect has not been reported with goldenseal.

Likelihood Possible Evidence D
Metformin (Glucophage)

Theoretically, goldenseal might reduce blood levels of metformin.
In vitro research shows that goldenseal extract decreases the bioavailability of metformin, likely by interfering with transport, intestinal permeability, or other processes involved in metformin absorption. It is unclear which, if any, of metformin's transporters are inhibited by goldenseal. Goldenseal does not appear to alter the clearance or half-life of metformin.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, goldenseal might increase or decrease serum levels of P-glycoprotein (P-gp) substrates.
There is conflicting evidence about the effect of goldenseal on P-gp. In vitro research suggests that berberine, a constituent of goldenseal, modestly inhibits P-gp efflux. Other evidence suggests that berberine induces P-gp. In healthy volunteers, goldenseal modestly increases peak levels of the P-gp substrate digoxin by about 14%. However, it does not seem to affect other pharmacokinetic parameters such as area under the curve (AUC). This suggests that goldenseal is not a potent inhibitor of P-gp-mediated drug efflux. Until more is known, goldenseal should be used cautiously with P-gp substrates.

Likelihood Probable Evidence B
Pentobarbital (Nembutal)

Theoretically, goldenseal might increase the sedative effects of pentobarbital.
Animal research shows that berberine, a constituent of goldenseal, can prolong pentobarbital-induced sleeping time. However, this effect has not been reported with goldenseal.

Likelihood Possible Evidence D
Tacrolimus (Prograf)

Theoretically, goldenseal might increase serum levels of tacrolimus.
Goldenseal contains berberine. In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of tacrolimus dosing to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL.

Likelihood Possible Evidence D
Oseltamivir (Tamiflu)

Theoretically, goldenseal might reduce the therapeutic effects of oseltamivir by decreasing its conversion to its active form.
In vitro evidence suggests that goldenseal reduces the formation of the active compound from the prodrug oseltamivir. The mechanism of action and clinical relevance is unclear.

Alkylating Agents

Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of alkylating agents but might also reduce the oxidative damage caused by certain alkylating agents.
Rose hip contains vitamin C. The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. Further, some animal research suggests that the antioxidant effects of rose hip might attenuate cyclophosphamide-induced testicular toxicity. More evidence is needed to determine what effect, if any, antioxidants found in rose hip, such as vitamin C, have on the effectiveness and adverse effects of chemotherapy.

Likelihood Possible Evidence D
Aluminum

Theoretically, rose hip might increase the amount of aluminum absorbed from aluminum compounds.
Rose hip contains vitamin C. Theoretically, vitamin C increases the absorption of aluminum. Concomitant use might increase aluminum absorption, but the clinical significance of this is unknown. Administer rose hip two hours before or four hours after antacids.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, rose hip might reduce the effectiveness of anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that a constituent of rose hip, rugosin E, can induce platelet aggregation. This has not been shown in humans. Theoretically, concomitant use of rose hip might reduce the effectiveness of antiplatelet or anticoagulant drugs.

Likelihood Possible Evidence D
Antitumor Antibiotics

Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of antitumor antibiotics.
Rose hip contains the antioxidant vitamin C. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as antitumor antibiotics. In contrast, other researchers theorize that antioxidants might make antitumor antibiotic chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on antitumor antibiotic chemotherapy.

Likelihood Possible Evidence D
Estrogens

Theoretically, rose hip might increase blood levels of estrogens.
Rose hip contains vitamin C. Increases in plasma estrogen levels of up to 55% have occured under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. However, increases in plasma estrogen levels may occur when women who are deficient in vitamin C take supplements.

Likelihood Possible Evidence D
Lithium

Theoretically, rose hip might increase blood levels of lithium.
Rose hip is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, rose hip might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D
Aspirin

Theoretically, rose hip might reduce the clearance of aspirin; however, its vitamin C content is likely too low to produce clinically significant effects.
Rose hip contains vitamin C. It has been suggested that acidification of the urine by vitamin C can decrease the urinary excretion of salicylates, increasing plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion. The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and aspirin is unlikely.

Likelihood Unlikely Evidence B
Warfarin (Coumadin)

Theoretically, rose hip might reduce the effectiveness of warfarin; however, its vitamin C content is likely too low to produce clinically significant effects.
Rose hip contains vitamin C. High doses of vitamin C may reduce the response to warfarin, possibly by causing diarrhea and reducing warfarin absorption. This occurred in two people who took up to 16 grams daily of vitamin C, and resulted in decreased prothrombin time. Lower doses of 5-10 grams daily of vitamin C can also reduce warfarin absorption, but this does not seem to be clinically significant. The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and warfarin is unlikely.

Myrrh Resin Extract2 drug types · 88 drugs

Antidiabetes Drugs

Theoretically, myrrh might increase the risk of hypoglycemia when taken with antidiabetes drugs.
In vitro and animal research suggests that myrrh has hypoglycemic effects.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, myrrh might decrease the effectiveness of warfarin.
In one case, a patient who was previously stable on warfarin had a significant decline in international normalized ratio (INR) following consumption of an aqueous extract of myrrh.

FVE-W by Pure Herbs: Common Questions

Does FVE-W by Pure Herbs interact with any medications?
Yes. Based on its ingredients, FVE-W has a known interaction with 1,283 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
FVE-W contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this while I'm on warfarin (Coumadin)?
No—two of the ingredients, dog rose and myrrh, may reduce how well warfarin works, and goldenseal may increase your bleeding risk if you're on an anticoagulant. Talk to your doctor or pharmacist before taking this product; they may need to monitor you more closely or adjust your dose.
Is this safe during pregnancy?
No. Goldenseal and myrrh are rated likely unsafe in pregnancy—goldenseal's berberine may harm the fetus and trigger contractions, and myrrh is traditionally thought to stimulate the uterus. Avoid this product and discuss safer options with your doctor or pharmacist.
What are the most common side effects?
Digestive upset is the main issue: flatulence, loose stools, diarrhea, nausea, abdominal cramping, and constipation have been reported. Most people tolerate the ingredients well, especially at lower doses.
Can I take this with my diabetes medication?
Probably not without close monitoring. Both goldenseal and myrrh may lower blood sugar, so taking them with diabetes drugs could increase your risk of low blood sugar (hypoglycemia). Check with your doctor or pharmacist before starting.
How much of this product do I need to take for it to work?
The product facts don't include a recommended dose, so check the bottle label. For most of these ingredients, evidence for what they're traditionally used for is limited or not yet established, so the dose that would be effective isn't clear from the research.
Does chickweed have any interactions?
No documented interactions are documented in our data for chickweed. However, safety data overall for chickweed at supplement doses are limited, so short-term use is recommended.
