HelloPharmacist Scorecard of Licorice Soothing Formula by Ron Teeguarden's Dragon 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
This formula contains two active ingredients. Chinese licorice root extract is traditionally used for soothing purposes and is backed by some evidence for canker sores and atopic dermatitis (eczema); the evidence for asthma and Addison disease isn't yet established.
White peony root extract has insufficient evidence to establish effectiveness for the conditions we have data on — aging skin, anal fissures, atherosclerosis, chronic fatigue, cirrhosis, and migraine. The capsule also contains inactive ingredients: pullulan polysaccharide, rice powder, bamboo extract powder, and a rice extract blend.
Does it work?
Moderate evidence
The evidence supporting licorice root for your health is modest. It's possibly effective for canker sores and atopic dermatitis (eczema) — the skin inflammation condition.
For asthma and Addison disease, the evidence isn't established in the data we hold. White peony root extract has no established effectiveness in our records for any of the conditions studied, including aging skin, anal fissures, atherosclerosis, chronic fatigue, cirrhosis, and migraine headache.
How safe is it?
Well-documented data
Licorice is generally well tolerated in small food amounts, but the compound glycyrrhizin — its active constituent — can cause serious problems with high doses or long-term use. The most common side effects when taken by mouth are headache, nausea, and vomiting.
Rare but serious effects include problems with blood pressure, fluid retention, and mineral imbalances. White peony is generally well tolerated for short-term use, though high-quality safety data are limited.
Oral side effects reported include abdominal bloating, loss of appetite, diarrhea, gastrointestinal discomfort, and nausea; diarrhea was reported in about 5% of patients in one clinical study. Neither ingredient has enough safety information for pregnancy or breastfeeding — avoid licorice in pregnancy (glycyrrhizin has been linked to harm) and avoid white peony in pregnancy as well.
Breastfeeding data are insufficient for both, so talk with your pharmacist or doctor.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist if you take digoxin (a heart medication), warfarin or other blood thinners, loop diuretics (water pills for the heart or kidneys), cancer drugs like paclitaxel or cisplatin, the sedative midazolam, birth control pills or hormone replacement therapy, the antipsychotic clozapine, the seizure medication phenytoin, or any drug broken down by your liver's CYP1A2, CYP2B6, CYP2C19, or CYP3A4 enzymes. All of these have documented moderate interactions with one or both active ingredients.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This formula is used for soothing purposes and has some evidence for eczema and canker sores, but it carries multiple moderate interactions with heart medications, blood thinners, cancer drugs, and other common prescriptions. If you take any regular medications — especially for the heart, blood clotting, seizures, or mental health — check with your pharmacist before starting.
Pregnant or breastfeeding? Skip it; the safety data aren't there.

Licorice Soothing Formula by Ron Teeguarden's Dragon Herbs Drug Interactions
HelloPharmacist Interaction Report
Ron Teeguarden's Dragon Herbs Licorice Soothing Formula contains two active ingredients — Chinese licorice root extract and white peony root extract — and both have documented interactions with medications.
The most serious concern is licorice's potential to increase the risk of heart rhythm problems (cardiac toxicity) when combined with digoxin, a heart medication.
Read the full breakdown — every affected drug type, severity by severity
Licorice interacts with several drug types. It may increase levels of medications broken down by your liver's CYP2B6 and CYP2C19 enzymes (Moderate severity).
It can reduce how well blood thinners like warfarin work by speeding up their breakdown (Moderate). Loop diuretics — water pills used for heart and kidney conditions — may have their effects amplified by licorice's mineral-balancing actions (Moderate).
Licorice may also weaken the effectiveness of the cancer drug paclitaxel, reduce levels of the sedative midazolam, and potentially interfere with cisplatin cancer therapy (all Moderate).
White peony root extract carries additional Moderate interactions. It may increase levels of drugs processed by your liver's CYP1A2 and CYP3A4 enzymes.
It has estrogenic activity, so it could interfere with birth control pills or hormone replacement therapy. It may raise bleeding risk if you take blood thinners or antiplatelet drugs like aspirin.
In theory, it could increase levels of the antipsychotic clozapine or reduce effectiveness of the seizure medication phenytoin, though these haven't been confirmed in humans.
Altogether, these interactions span 1,082 individual medications. Use the search tool below to check your exact medications before starting this product.

For each ingredient in Licorice Soothing Formula 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 Licorice root extract
Antihypertensive Drugs
Theoretically, licorice might reduce the effects of antihypertensive drugs.
In human research, licorice increases blood pressure in a dose-dependent manner.
Cisplatin (Platinol-Aq)
Theoretically, licorice might reduce the effects of cisplatin.
In animal research, licorice diminished the therapeutic efficacy of cisplatin.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
P-Glycoprotein Substrates
Theoretically, licorice might decrease the absorption of P-glycoprotein substrates.
In vitro research shows that licorice can increase P-glycoprotein activity.
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.
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.
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.
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.
White Peony root extract
Anticoagulant/Antiplatelet Drugs
Theoretically, combining peony with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that peony might have antiplatelet, anticoagulant, and antithrombotic effects.
Clozapine (Clozaril)
Theoretically, peony might increase the levels and clinical effects of clozapine.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on cytochromes P450 (CYP) 1A2 and CYP3A4. This effect has not been reported in humans.
Contraceptive Drugs
Theoretically, peony might interfere with contraceptive drugs due to competition for estrogen receptors.
In vitro and animal research shows that peony extract has estrogenic activity. Concomitant use might also increase the risk for estrogen-related adverse effects.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.
Estrogens
Theoretically, concomitant use of large amounts of peony might interfere with hormone replacement therapy and/or increase the risk for estrogen-related adverse effects.
In vitro and animal research shows that peony extract has estrogenic activity. Theoretically, peony might compete for estrogen receptors and/or cause additive estrogenic effects.
Phenytoin (Dilantin)
Theoretically, peony might reduce the levels and clinical effects of phenytoin.
Animal research shows that taking peony root reduces levels of phenytoin. Some researchers suggest that peony root might affect cytochrome P450 (CYP) 2C9, which metabolizes phenytoin. However, preliminary research in humans shows that peony root does not alter levels of losartan (Cozaar), which is also metabolized by CYP2C9.
