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 6 active ingredients.
  • “Proprietary Blend Extract” is a proprietary blend — the label gives one combined amount (2.25 mL) without saying how much of each component you get.

Dew Drops contains 6 ingredients, including American Ginseng root extract (traditionally used to support upper respiratory health), Chinese Licorice root extract (used in traditional medicine for skin and digestive support), Poria sclerotium extract (a mushroom used in traditional practice), Chinese Asparagus Root Extract, Pseudostellaria Root Tuber Extract, and Lily Flower extract. The product is delivered as a liquid in a base of water and grain alcohol.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: skin, mucous tissues, lung and sinus health.
  • We looked for evidence on: Allergic rhinitis (hay fever), Asthma, Atopic dermatitis (eczema), Dry mouth, Upper respiratory tract infection (URTI), sinusitis — and 2 related terms.
  • The strongest evidence on file: Licorice is rated "Possibly Effective" for Atopic dermatitis (eczema) (Natural Medicines).
  • Also on file: American Ginseng is rated "Possibly Effective" for Upper respiratory tract infection (URTI).
  • Also on file: Licorice is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever), Asthma, Dry mouth.

American ginseng is rated possibly effective for upper respiratory tract infections. Chinese licorice is possibly effective for canker sores and eczema.

For the other ingredients — Poria mushroom, Chinese Asparagus, Pseudostellaria, and Lily Flower — the evidence we hold is insufficient to rate their effectiveness for any condition listed in our data.

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.

American ginseng is generally well tolerated short-term in healthy adults, though long-term safety isn't well studied; headache has been reported. Chinese licorice is generally fine in small food amounts, but high doses or long-term use of products containing glycyrrhizin can cause serious problems including headache, nausea, vomiting, and in rare cases, dangerous electrolyte changes.

Poria mushroom is generally well tolerated in traditional use but has limited human safety data; allergic reactions have been reported rarely. Lily-of-the-valley is toxic and unsafe — all parts can cause life-threatening heart problems including dangerous heart rhythms, headache, and visual disturbances.

For pregnancy and breastfeeding: American ginseng is rated possibly unsafe during pregnancy and should be avoided while breastfeeding. Chinese licorice is unsafe in pregnancy and should be avoided while breastfeeding.

Poria mushroom should be avoided in both pregnancy and breastfeeding due to insufficient safety data. Lily-of-the-valley is likely unsafe in both pregnancy and breastfeeding.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 4 of the 4 matched ingredients can interact with medications — Poria Mushroom, Lily-of-the-valley, Licorice, American Ginseng.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 1,421 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 taking Dew Drops, check with your doctor or pharmacist if you take blood thinners like warfarin, heart medications including digoxin or corticosteroids, diabetes drugs, antidepressants (especially MAOIs), sedatives, diuretics, lithium, immune-suppressing drugs, stimulant laxatives, or certain antibiotics. The lily flower extract in this product is noted as toxic in our data and poses serious cardiac risks with multiple medication classes.

Chinese Licorice root extract18 drug types · 1,040 drugs

Antihypertensive Drugs

Theoretically, licorice might reduce the effects of antihypertensive drugs.
In human research, licorice increases blood pressure in a dose-dependent manner.

Likelihood Possible Evidence B
Cisplatin (Platinol-Aq)

Theoretically, licorice might reduce the effects of cisplatin.
In animal research, licorice diminished the therapeutic efficacy of cisplatin.

Likelihood Possible Evidence D
Corticosteroids

Theoretically, concomitant use of licorice and corticosteroids might increase the side effects of corticosteroids.
Case reports suggest that concomitant use of licorice and oral corticosteroids, such as hydrocortisone, can potentiate the duration of activity and increase blood levels of corticosteroids. Additionally, in one case report, a patient with neurogenic orthostatic hypertension stabilized on fludrocortisone 0.1 mg twice daily developed pseudohyperaldosteronism after recent consumption of large amounts of black licorice.

Likelihood Possible Evidence D
Cytochrome P450 2B6 (Cyp2B6) Substrates

Theoretically, licorice might increase levels of drugs metabolized by CYP2B6.
In vitro research shows that licorice extract and glabridin, a licorice constituent, inhibit CYP2B6 isoenzymes. Licorice extract from the species G. uralensis seems to inhibit CYP2B6 isoenzymes to a greater degree than G. glabra extract in vitro. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2B6; however, these interactions have not yet been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, licorice might increase levels of drugs metabolized by CYP2C19.
In vitro, licorice extracts from the species G. glabra and G. uralensis inhibit CYP2C19 isoenzymes in vitro. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2C19; however, this interaction has not yet been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C8 (Cyp2C8) Substrates

Theoretically, licorice might increase levels of drugs metabolized by CYP2C8.
In vitro, licorice extract from the species G. glabra and G. uralensis inhibits CYP2C8 isoenzymes. Theoretically, these species of licorice might increase levels of drugs metabolized by CYP2C8; however, this interaction has not yet been reported in humans.

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

Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP2C9.
There is conflicting evidence about the effect of licorice on CYP2C9 enzyme activity. In vitro research shows that extracts from the licorice species G. glabra and G. uralensis moderately inhibit CYP2C9 isoenzymes. However, evidence from an animal model shows that licorice extract from the species G. uralensis can induce hepatic CYP2C9 activity. Until more is known, licorice should be used cautiously in people taking CYP2C9 substrates.

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

Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP3A4.
Pharmacokinetic research shows that the licorice constituent glycyrrhizin, taken in a dosage of 150 mg orally twice daily for 14 days, modestly decreases the area under the concentration-time curve of midazolam by about 20%. Midazolam is a substrate of CYP3A4, suggesting that glycyrrhizin modestly induces CYP3A4 activity. Animal research also shows that licorice extract from the species G. uralensis induces CYP3A4 activity. However, licorice extract from G. glabra species appear to inhibit CYP3A4-induced metabolism of testosterone in vitro. It is thought that the G. glabra inhibits CYP3A4 due to its constituent glabridin, which is a moderate CYP3A4 inhibitor in vitro and not present in other licorice species. Until more is known, licorice should be used cautiously in people taking CYP3A4 substrates.

Likelihood Possible Evidence B
Digoxin (Lanoxin)

Theoretically, concomitant use of licorice with digoxin might increase the risk of cardiac toxicity.
Overuse or misuse of licorice with cardiac glycoside therapy might increase the risk of cardiac toxicity due to potassium loss.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, concomitant use of licorice with diuretic drugs might increase the risk of hypokalemia.
Overuse of licorice might compound diuretic-induced potassium loss. In one case report, a 72-year-old male with a past medical history of hypertension, type 2 diabetes, hyperlipidemia, arrhythmia, stroke, and hepatic dysfunction was hospitalized with severe hypokalemia and uncontrolled hypertension due to pseudohyperaldosteronism. This was thought to be provoked by concomitant daily consumption of a product containing 225 mg of glycyrrhizin, a constituent of licorice, and hydrochlorothiazide 12.5 mg for 1 month.

Likelihood Possible Evidence D
Estrogens

Theoretically, licorice might increase or decrease the effects of estrogen therapy.
Theoretically, licorice might interfere with estrogen therapy due to estrogenic and anti-estrogenic effects.

Likelihood Possible Evidence D
Loop Diuretics

Theoretically, loop diuretics might increase the mineralocorticoid effects of licorice.
Theoretically, loop diuretics might enhance the mineralocorticoid effects of licorice by inhibiting the enzyme that converts cortisol to cortisone; however, bumetanide (Bumex) does not appear to have this effect.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, licorice might decrease levels of midazolam.
In humans, the licorice constituent glycyrrhizin appears to moderately induce the metabolism of midazolam. This is likely due to induction of cytochrome P450 3A4 by licorice. Until more is known, licorice should be used cautiously in people taking midazolam.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Theoretically, licorice might decrease the absorption of P-glycoprotein substrates.
In vitro research shows that licorice can increase P-glycoprotein activity.

Likelihood Possible Evidence D
Paclitaxel (Abraxane, Onxol)

Theoretically, licorice might decrease plasma levels and clinical effects of paclitaxel.
Multiple doses of licorice taken concomitantly with paclitaxel might reduce the effectiveness of paclitaxel. Animal research shows that licorice 3 grams/kg given orally for 14 days before intravenous administration of paclitaxel decreases the exposure to paclitaxel and increases its clearance. Theoretically, this occurs because licorice induces cytochrome P450 3A4 enzymes, which metabolize paclitaxel. Notably, a single dose of licorice did not affect exposure or clearance of paclitaxel.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, licorice might decrease plasma levels and clinical effects of warfarin.
Licorice seems to increase metabolism and decrease levels of warfarin in animal models. This is likely due to induction of cytochrome P450 2C9 (CYP2C9) metabolism by licorice. Advise patients taking warfarin to avoid taking licorice.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, licorice might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that licorice induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Methotrexate (Trexall, Others)

Theoretically, licorice might increase levels of methotrexate.
Animal research suggests that intravenous administration of glycyrrhizin, a licorice constituent, and high-dose methotrexate may delay methotrexate excretion and increase systemic exposure, leading to transient elevations in liver enzymes and total bilirubin. This interaction has not yet been reported in humans.

Anticholinergic Drugs

Theoretically, poria mushroom might decrease the clinical effects of anticholinergic drugs.
In animal research, poria mushroom essential oil reduces acetylcholinesterase activity. This interaction has not been shown in humans.

Cholinergic Drugs

Theoretically, poria mushroom might have additive effects when used with cholinergic drugs.
In animal research, poria mushroom essential oil reduces acetylcholinesterase activity. This interaction has not been shown in humans.

American Ginseng root extract4 drug types · 217 drugs

Warfarin (Coumadin)

American ginseng seems to decrease the effectiveness of warfarin therapy.
Healthy patients receiving warfarin 5 mg daily, who also take American ginseng 1 gram twice daily, seem to have a significantly reduced international normalized ratio (INR).

Likelihood Likely Evidence B
Antidiabetes Drugs

Theoretically, taking American ginseng with antidiabetes drugs might increase the risk of hypoglycemia.
American ginseng seems to lower postprandial blood glucose. Theoretically, concomitant use with antidiabetes drugs might enhance blood glucose lowering effects and possibly cause hypoglycemia.

Likelihood Probable Evidence B
Immunosuppressants

Theoretically, American ginseng use might interfere with immunosuppressive therapy.
American ginseng seems to stimulate immune function. Theoretically, American ginseng might decrease the effectiveness of immunosuppressant drugs.

Likelihood Possible Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, American ginseng can interfere with MAOI therapy.
There is one case report of insomnia, headache, and tremors when an unspecified ginseng product was used with phenelzine (Nardil), an MAOI. There is also one case report of hypomania when an unspecified ginseng product was used with phenelzine. Theoretically, American ginseng may interfere with MAOI therapy.

Likelihood Possible Evidence D
American Ginseng root extract full monograph & interactions

Lily Flower Extract8 drug types · 157 drugs

Corticosteroids

Theoretically, using lily-of-the-valley with prolonged corticosteroid therapy can cause cardiac glycoside toxicity.
Lily-of-the-valley contains cardiac glycosides. Concomitant, long-term corticosteroid use can increase the risk of cardiac glycoside toxicity due to potassium depletion and electrolyte imbalance.

Likelihood Probable Evidence D
Digoxin (Lanoxin)

Using lily-of-the-valley with digoxin can cause cardiac glycoside toxicity.
Lily-of-the-valley contains cardiac glycosides. Use of the cardiac glycoside digoxin and lily-of-the-valley concomitantly increases the risk of cardiac glycoside toxicity.

Likelihood Likely Evidence D
Quinine

Theoretically, using lily-of-the-valley with quinine can increase the risk of cardiac glycoside toxicity.
Quinine may reduce the clearance of oral digoxin. Theoretically, concomitant use of quinine with lily-of-the-valley might reduce the clearance of cardiac glycosides found in lily-of-the-valley and increase the risk of toxicity.

Likelihood Probable Evidence D
Diuretic Drugs

Theoretically, using lily-of-the-valley with diuretics can increase the risk of cardiac glycoside toxicity.
Lily-of-the-valley contains cardiac glycosides. Concomitant use of potassium depleting diuretics and lily-of-the-valley can increase the risk of cardiac glycoside toxicity due to potassium depletion and electrolyte imbalance.

Likelihood Possible Evidence D
Lithium

Theoretically, lily-of-the-valley can increase levels of lithium and increase toxicity.
Lily-of-the-valley is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, lily-of-the-valley might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D
Macrolide Antibiotics

Theoretically, using lily-of-the-valley with macrolide antibiotics can increase the risk of cardiac glycoside toxicity.
Macrolide antibiotics appear to increase the gastrointestinal absorption of oral digoxin. Theoretically, concomitant use of macrolide antibiotics might increase the absorption of the cardiac glycosides found in lily-of-the-valley.

Likelihood Possible Evidence D
Stimulant Laxatives

Theoretically, using lily-of-the-valley with stimulant laxatives can increase the risk of cardiac glycoside toxicity.
Lily-of-the-valley contains cardiac glycosides. The overuse of stimulant laxatives can increase the risk of cardiac glycoside toxicity with lily-of-the-valley due to potassium depletion.

Likelihood Possible Evidence D
Tetracycline Antibiotics

Theoretically, using lily-of-the-valley with tetracycline antibiotics might increase the risk of cardiac glycoside toxicity.
Tetracycline antibiotics appear to increase the gastrointestinal absorption of oral digoxin, a cardiac glycoside. Theoretically, concomitant use of tetracycline antibiotics might increase the absorption of the cardiac glycosides found in lily-of-the-valley.

Dew Drops by Ron Teeguarden's Dragon Herbs: Common Questions

Does Dew Drops by Ron Teeguarden's Dragon Herbs interact with any medications?
Yes. Based on its ingredients, Dew Drops has a known interaction with 1,420 medications, including 28 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Dew Drops contains 6 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 if I'm pregnant?
The safety data advises against it. American ginseng is rated possibly unsafe in pregnancy, Chinese licorice is unsafe, poria mushroom lacks sufficient data, and lily-of-the-valley is likely unsafe. Talk with your doctor or pharmacist before taking this product during pregnancy.
Does American ginseng really help with colds?
American ginseng is rated possibly effective for upper respiratory tract infections in our data. That means some evidence supports it, but it's not proven to work reliably for everyone.
What's lily flower extract in here for?
According to our data, lily-of-the-valley (the Lily Flower ingredient) has insufficient evidence for heart-related uses. However, our safety notes flag it as toxic and capable of causing life-threatening heart problems, so its presence in a supplement raises serious concerns.
Are there side effects?
American ginseng may cause headache. Chinese licorice can cause headache, nausea, and vomiting, especially with long-term or high-dose use. Poria mushroom rarely causes allergic reactions. Lily-of-the-valley can cause dangerous heart rhythms, headache, and visual color disturbances and is unsafe to use.
Can I take this while breastfeeding?
No — the safety data advises against it. All four ingredients with monographs recommend avoiding this product while breastfeeding due to insufficient or unsafe data.
Why does the label show six ingredients but I only recognize a few?
Two of the six ingredients — Chinese Asparagus Root Extract and Pseudostellaria Root Tuber Extract — don't have interaction or effectiveness data on file for us to review. The other four are documented herbal extracts.
