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 7 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (1,500 mg) without saying how much of each component you get.

The Great Regulator contains seven active ingredients in a proprietary extract blend. The key ingredients are Chinese ginseng root extract, bupleurum root extract, red jujube date extract, Chinese licorice root extract, fresh ginger rhizome extract, prepared pinellia rhizome extract, and scutellaria (skullcap) root extract powder.

These are combined with inactive ingredients—pullulan, rice powder, bamboo extract, and rice extract blend—that serve as fillers and capsule material.

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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Cognitive function — rated "Possibly Effective" (Panax Ginseng) (Natural Medicines).
  • On file: Atopic dermatitis (eczema) — rated "Possibly Effective" (Licorice) (Natural Medicines).
  • On file: Erectile dysfunction (ED) — rated "Possibly Effective" (Panax Ginseng) (Natural Medicines).
  • On file: Influenza — rated "Possibly Effective" (Panax Ginseng) (Natural Medicines).
  • On file: Multiple sclerosis-related fatigue — rated "Possibly Effective" (Panax Ginseng) (Natural Medicines).

The evidence for effectiveness is mixed and mostly limited. Ginger shows the strongest data: it's possibly effective for pregnancy-related nausea and vomiting, menstrual cramps (dysmenorrhea), and osteoarthritis.

Licorice is possibly effective for atopic dermatitis (eczema) and canker sores. For the other ingredients—Chinese ginseng, bupleurum, pinellia, and skullcap—the data we hold shows insufficient reliable evidence to rate them for the conditions they're traditionally used for, including asthma, liver cancer, epilepsy, stress, and stroke.

The product itself has no established effectiveness rating 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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Ginger is generally well tolerated in typical supplement doses, though it can cause heartburn, abdominal discomfort, diarrhea, or burping—and doses above 5 grams per day increase these mild side effects. Licorice is fine in small food amounts but can cause serious problems at high doses or with long-term use; common side effects include headache, nausea, and vomiting.

Bupleurum and skullcap have limited safety data and quality can vary. Skullcap may cause sedation, cognitive impairment, or mild digestive disturbances.

Bupleurum has been linked to rare but serious lung and liver problems when used in formulas, though it's typically short-term. Licorice should be avoided in pregnancy because of potential harm; skullcap and bupleurum also lack enough safety data for pregnancy and are best avoided.

None of these ingredients have adequate breastfeeding data.

Chinese Ginseng root extract20 drug types · 1,130 drugs

Anticoagulant/Antiplatelet Drugs

Although Panax ginseng has shown antiplatelet effects in the laboratory, it is unlikely to increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that ginsenoside constituents in Panax ginseng might decrease platelet aggregation. However, research in humans suggests that ginseng does not affect platelet aggregation. Animal research indicates low oral bioavailability of Rb1 and rapid elimination of Rg1, which might explain the discrepancy between in vitro and human research. Until more is known, use with caution in patients concurrently taking anticoagulant or antiplatelet drugs.

Likelihood Unlikely Evidence B
Antidiabetes Drugs

Theoretically, taking Panax ginseng with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research suggests that Panax ginseng might decrease blood glucose levels. Monitor blood glucose levels closely.

Likelihood Probable Evidence B
Caffeine

Theoretically, taking Panax ginseng with caffeine might increase the risk of adverse stimulant effects.
Panax ginseng has been shown to have stimulant effects. Theoretically, caffeine might have an additive effect on the stimulant effects of Panax ginseng.

Likelihood Probable Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, Panax ginseng might increase levels of drugs metabolized by CYP2D6. However, research is conflicting.
There is some evidence that Panax ginseng can inhibit the CYP2D6 enzyme by approximately 6%. In addition, in animal research, Panax ginseng inhibits the metabolism of dextromethorphan, a drug metabolized by CYP2D6, by a small amount. However, contradictory research suggests Panax ginseng might not inhibit CYP2D6. Until more is known, use Panax ginseng cautiously in patients taking drugs metabolized by these enzymes.

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

Theoretically, Panax ginseng might increase or decrease levels of drugs metabolized by CYP3A4.
Panax ginseng may affect the clearance of drugs metabolized by CYP3A4. One such drug is imatinib. Inhibition of CYP3A4 was believed to be responsible for a case of imatinib-induced hepatotoxicity. In contrast, Panax ginseng has been shown to increase the clearance of midazolam, another drug metabolized by CYP3A4. Clinical research shows that Panax ginseng can reduce midazolam area under the curve by 44%, maximum plasma concentration by 26%, and time to reach maximum plasma concentration by 29%. Midazolam metabolism was also increased in animals given Panax ginseng. Until more is known, use Panax ginseng cautiously in combination with CYP3A4 substrates.

Likelihood Possible Evidence B
Estrogens

Theoretically, concomitant use of large amounts of Panax ginseng might interfere with hormone replacement therapy.
Laboratory research and some case reports suggest that Panax ginseng can have estrogenic effects due to competition for estrogen receptors. The estrogenic activity is attributed to the ginsenoside constituents of Panax ginseng.

Likelihood Possible Evidence D
Furosemide (Lasix)

Theoretically, Panax ginseng might reduce the effects of furosemide.
There is some concern that Panax ginseng might contribute to furosemide resistance. There is one case of resistance to furosemide diuresis in a patient taking a germanium-containing ginseng product.

Likelihood Possible Evidence D
Imatinib (Gleevec)

Theoretically, Panax ginseng might increase the effects and adverse effects of imatinib.
A case of imatinib-induced hepatotoxicity has been reported for a 26-year-old male with chronic myelogenous leukemia stabilized on imatinib for 7 years. The patient took imatinib 400 mg along with a Panax ginseng-containing energy drink daily for 3 months. Since imatinib-associated hepatotoxicity typically occurs within 2 years of initiating therapy, it is believed that Panax ginseng affected imatinib toxicity though inhibition of cytochrome P450 3A4. CYP3A4 is the primary enzyme involved in imatinib metabolism.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, Panax ginseng use might interfere with immunosuppressive therapy.
Panax ginseng might have immune system stimulating properties.

Likelihood Possible Evidence B
Insulin

Theoretically, taking Panax ginseng with insulin might increase the risk of hypoglycemia.
Clinical research suggests that Panax ginseng might decrease blood glucose levels. Insulin dose adjustments might be necessary in patients taking Panax ginseng; use with caution.

Likelihood Probable Evidence B
Midazolam (Versed)

Theoretically, Panax ginseng may increase the clearance of midazolam.
Midazolam is metabolized by cytochrome P450 3A4 (CYP3A4). Clinical research suggests that Panax ginseng can reduce midazolam area under the curve by 44%, maximum plasma concentration by 26%, and time to reach maximum plasma concentration by 29%. Midazolam metabolism was also increased in animals given Panax ginseng.

Likelihood Probable Evidence B
Monoamine Oxidase Inhibitors (Maois)

Theoretically, Panax ginseng can interfere with MAOI therapy.
Concomitant use of Panax ginseng with phenelzine (Nardil) is associated with insomnia, headache, tremors, and hypomania.

Likelihood Probable Evidence D
Nifedipine (Procardia)

Theoretically, taking Panax ginseng with nifedipine might increase serum levels of nifedipine and the risk of hypotension.
Preliminary clinical research shows that concomitant use can increase serum levels of nifedipine in healthy volunteers. This might cause the blood pressure lowering effects of nifedipine to be increased when taken concomitantly with Panax ginseng.

Likelihood Possible Evidence B
Qt Interval-Prolonging Drugs

Theoretically, Panax ginseng has an additive effect with drugs that prolong the QT interval and potentially increase the risk of ventricular arrhythmias. However, research is conflicting.
Clinical research shows that short-term use of Panax ginseng can increase the QT interval. However, no changes in QT interval have been identified with prolonged use.

Likelihood Possible Evidence B
Raltegravir (Isentress)

Theoretically, taking Panax ginseng with raltegravir might increase the risk of liver toxicity.
A case report suggests that concomitant use of Panax ginseng with raltegravir can increase serum levels of raltegravir, resulting in elevated liver enzymes levels.

Likelihood Possible Evidence D
Selegiline (Eldepryl)

Theoretically, Panax ginseng might increase or decrease levels of selegiline, possibly altering the effects and side effects of selegiline.
Animal research shows that taking selegiline with a low dose of Panax ginseng extract (1 gram/kg) reduces selegiline bioavailability, while taking a high dose of Panax ginseng extract (3 grams/kg) increases selegiline bioavailability. More research is needed to confirm these effects.

Likelihood Possible Evidence D
Stimulant Drugs

Theoretically, taking Panax ginseng with stimulant drugs might increase the risk of adverse stimulant effects.
Panax ginseng has been shown to have stimulant effects.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Panax ginseng might affect the clearance of warfarin. However, this interaction appears to be unlikely.
There has been a single case report of decreased effectiveness of warfarin in a patient who also took Panax ginseng. However, it is questionable whether Panax ginseng was the cause of this decrease in warfarin effectiveness. Some research in humans and animals suggests that Panax ginseng does not affect the pharmacokinetics of warfarin. However, other research in humans suggests that Panax ginseng might modestly increase the clearance of the S-warfarin isomer. More evidence is needed to determine whether Panax ginseng causes a significant interaction with warfarin.

Likelihood Unlikely Evidence B
Fexofenadine (Allegra)

Theoretically, Panax ginseng might decrease blood levels of oral or intravenous fexofenadine.
Animal research suggests that taking Panax ginseng in combination with oral or intravenous fexofenadine may reduce the bioavailability of fexofenadine. Some scientists have attributed this effect to the ability of Panax ginseng to increase the expression of P-glycoprotein.

Likelihood Possible Evidence D
Lopinavir/Ritonavir (Kaletra)

Although Panax ginseng has demonstrated variable effects on cytochrome P450 3A4 (CYP3A4), which metabolizes lopinavir, Panax ginseng is unlikely to alter levels of lopinavir/ritonavir.
Lopinavir is metabolized by CYP3A4 and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Panax ginseng has shown variable effects on CYP3A4 activity in humans. However, taking Panax ginseng (Vitamer Laboratories) 500 mg twice daily for 14 days did not alter the pharmacokinetics of lopinavir/ritonavir in 12 healthy volunteers.

Likelihood Unlikely Evidence B
Chinese Ginseng root extract full monograph & interactions

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.

Ginger Rhizome Extract, Fresh14 drug types · 1,007 drugs

Anticoagulant/Antiplatelet Drugs

Ginger may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Laboratory research suggests that ginger inhibits thromboxane synthetase and decreases platelet aggregation. However, this has not been demonstrated unequivocally in humans, with mixed results from clinical trials. Theoretically, excessive amounts of ginger might increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking ginger with antidiabetes drugs might increase the risk of hypoglycemia.
Animal and human research suggests that ginger might increase insulin levels and/or decrease blood glucose levels.

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

Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Losartan (Cozaar)

Theoretically, ginger might increase levels of losartan and the risk of hypotension.
In animal research, ginger increased the levels and hypotensive effects of a single dose of losartan. It is not clear if ginger alters the concentration or effects of losartan when taken continuously. Additionally, this interaction has not been shown in humans.

Likelihood Possible Evidence D
Nifedipine (Procardia)

Ginger may have antiplatelet effects and increase the risk of bleeding if used with nifedipine.
Clinical research shows that combined treatment with ginger 1 gram plus nifedipine 10 mg significantly inhibits platelet aggregation when compared to nifedipine or ginger alone.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Ginger might increase the absorption and blood levels of P-glycoprotein (P-gp) substrates.
In vitro research and case reports suggest that ginger inhibits drug efflux by P-gp, potentially increasing absorption and serum levels of P-gp substrates. Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are P-gp substrates (trametinib, crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.

Likelihood Possible Evidence D
Phenprocoumon (Marcoumar, Others)

Ginger might increase the risk of bleeding with phenprocoumon.
Phenprocoumon, a warfarin-related anticoagulant, might increase the international normalized ratio (INR) when taken with ginger. There is one case report of a 76-year-old woman with a stable INR on phenprocoumon that increased to greater than 10 when she began consuming dried ginger and ginger tea.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Ginger might increase the risk of bleeding with warfarin.
Laboratory research suggests that ginger might inhibit thromboxane synthetase and decrease platelet aggregation. In one case report, ginger increased the INR when taken with phenprocoumon, which has similar pharmacological effects as warfarin. In another case report, ginger increased the INR when taken with a combination of warfarin, hydrochlorothiazide, and acetaminophen. A longitudinal analysis suggests that taking ginger increases the risk of bleeding in patients taking warfarin for at least 4 months. However, research in healthy people suggests that ginger has no effect on INR, or the pharmacokinetics or pharmacodynamics of warfarin. Until more is known, monitor INRs closely in patients taking large amounts of ginger.

Likelihood Possible Evidence B
Calcium Channel Blockers

Theoretically, taking ginger with calcium channel blockers might increase the risk of hypotension.
Some animal and in vitro research suggests that ginger has hypotensive and calcium channel-blocking effects. Another animal study shows that concomitant administration of ginger and the calcium channel blocker amlodipine leads to greater reductions in blood pressure when compared with amlodipine alone.

Likelihood Unlikely Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, when taken prior to cyclosporine, ginger might decrease cyclosporine levels.
In an animal model, ginger juice taken 2 hours prior to cyclosporine administration reduced the maximum concentration and area under the curve of cyclosporine by 51% and 40%, respectively. This effect was not observed when ginger juice and cyclosporine were administered at the same time.

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

Theoretically, ginger might increase the levels of CYP1A2 substrates.
In vitro research shows that ginger inhibits CYP1A2 activity. However, this interaction has not been reported in humans.

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

Theoretically, ginger might increase the levels of CYP2B6 substrates.
In vitro research shows that ginger inhibits CYP2B6 activity. However, this interaction has not been reported in humans.

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

Theoretically, ginger might increase the levels of CYP2C9 substrates.
In vitro research shows that ginger inhibits CYP2C9 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Metronidazole (Flagyl)

Theoretically, ginger might increase levels of metronidazole.
In an animal model, ginger increased the absorption and plasma half-life of metronidazole. In addition, the elimination rate and clearance of metronidazole was significantly reduced.

Anticoagulant/Antiplatelet Drugs

Theoretically, bupleurum might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research suggests that saikosaponins, constituents of bupleurum, can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, bupleurum might decrease the effects of antidiabetes drugs.
Animal research suggests that saikosaponins, constituents of bupleurum, can increase blood glucose.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, bupleurum might decrease the effects of immunosuppressants.
In vitro and animal research suggests that bupleurum might stimulate immune function.

The Great Regulator by Ron Teeguarden's Dragon Herbs: Common Questions

Does The Great Regulator by Ron Teeguarden's Dragon Herbs interact with any medications?
Yes. Based on its ingredients, The Great Regulator has a known interaction with 1,454 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
The Great Regulator contains 7 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.
Is it safe to take this while I'm pregnant?
The data advises against it. Licorice, bupleurum, and skullcap should all be avoided in pregnancy because there isn't enough safety information or because they've been linked to potential harm. Ginger is often used for morning sickness, but you should check with your doctor first and keep the amount moderate. Talk to your doctor or pharmacist about whether this product is right for you.
What does ginger do in this formula?
Ginger is possibly effective for pregnancy-related nausea and vomiting, menstrual cramps, and osteoarthritis. In this blend, it's likely included for digestive or anti-inflammatory support, though the overall effectiveness of the formula depends on all its ingredients working together.
Can ginger in this product cause side effects?
Yes. The most common ones are heartburn, abdominal discomfort, diarrhea, burping, and a peppery irritation in your mouth or throat. These are usually mild and more likely at doses above 5 grams per day. Taking it as an encapsulated supplement may help reduce these.
What is licorice in here for, and is it safe?
Licorice is possibly effective for atopic dermatitis (eczema) and canker sores. It's fine in small food amounts, but high doses or long-term use can cause serious problems—headache, nausea, and vomiting are common side effects. Because this is a supplement blend, ask your pharmacist about the total licorice dose you're getting.
Why does skullcap matter if it has so little evidence?
Skullcap is traditionally used for stress and seizures, but the evidence is insufficient to rate it for these uses. What matters more here is that it can cause sedation and cognitive impairment, especially at higher doses, and it shouldn't be mixed with sleep aids or other sedative medications.
