HelloPharmacist Scorecard of Regeneration by Health Concerns

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
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 11 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (750 mg) without saying how much of each component you get.

Regeneration contains 11 ingredients in a proprietary blend. The active ones are Tang Kuei (Dong Quai), Moutan, Scute (Baikal Skullcap), White Peony, Gentiana, Sparganium, Persica, Tienchi, Kirin Ginseng, Zedoaria, and Qin Jiao — traditional Chinese herbs used in formulas for various purposes.

The product also contains inactive ingredients: vegetable gum, silicon dioxide, stearic acid, and cellulose, which serve as binders and capsule materials.

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

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: Angina — rated "Possibly Effective" (Panax Notoginseng) (Natural Medicines).
  • On file: Intracranial hemorrhage — rated "Possibly Effective" (Panax Notoginseng) (Natural Medicines).
  • On file: Stroke — rated "Possibly Effective" (Panax Notoginseng) (Natural Medicines).

The evidence supporting Regeneration's ingredients is not established in the data we hold. Tang Kuei, Baikal Skullcap, White Peony, Gentiana, and Zedoary have all been studied for various health purposes — iron deficiency anemia, anxiety, migraine, blood sugar control, wound healing, and others — but the evidence in each case is rated as insufficient to make a reliable recommendation.

If you're considering this product for a specific health goal, your pharmacist or doctor can help you weigh what's known and what's still uncertain.

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 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these herbs are generally well-tolerated when taken by mouth. The most common side effects are digestive — burping, flatulence, abdominal pain, nausea, diarrhea, and constipation.

Tang Kuei can increase sun sensitivity and may increase bleeding risk; Baikal Skullcap can cause abdominal pain and nausea; and White Peony may cause diarrhea (reported in about 5% of people in one study). Baikal Skullcap has rare reports of liver injury and lung inflammation linked to a specific product.

Tang Kuei contains compounds that are potentially cancer-causing, but whether they're present in amounts high enough to matter with supplement doses is unknown. Pregnancy and breastfeeding: Tang Kuei should be avoided during pregnancy because it may stimulate the uterus and affect bleeding, and there isn't enough safety data for breastfeeding.

Baikal Skullcap and White Peony lack enough safety data for both pregnancy and breastfeeding — talk with your doctor or pharmacist for personalized guidance. Zedoary is considered likely unsafe in pregnancy because it may affect the uterus, and there isn't enough data for breastfeeding.

Gentiana and the other ingredients we could not check do not have pregnancy/lactation data on file — discuss with your healthcare provider if you're pregnant, planning to become pregnant, or breastfeeding.

Why this rating?
  • 6 of the 6 matched ingredients can interact with medications — Peony, Zedoary, Gentian, Baikal Skullcap, Panax Notoginseng, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 1,255 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.

Blood thinners (anticoagulants) like warfarin — Tang Kuei carries a Major interaction that can increase bleeding. Blood pressure medications, diabetes drugs, psychiatric medications (especially clozapine), hormone replacement therapy, birth control pills, thyroid-suppressing drugs, lithium, and drugs metabolized by the liver enzyme CYP3A4 all have documented Moderate interactions.

Each ingredient & the kinds of drugs it affects

For each ingredient in Regeneration 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.

Scute12 drug types · 946 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, Baikal skullcap might increase the risk of bleeding when used concomitantly with anticoagulant and antiplatelet drugs.
Preliminary clinical research suggests that taking capsules containing a combination of astragalus, goldthread, and Baikal skullcap daily for 4 weeks inhibits platelet aggregation; the effect seems to be similar to that of aspirin 50 mg daily. It is unclear if this effect is due to Baikal skullcap, other ingredients, or the combination.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of Baikal skullcap with antidiabetes drugs might enhance blood glucose lowering effects.
Baicalein, a constituent of Baikal skullcap, has alpha-glucosidase inhibitory activity in vitro. Animal research also suggests that Baikal skullcap enhances the antidiabetic effects of metformin. However, in a small human study, taking Baikal skullcap extract did not enhance the antidiabetic effects of metformin, although it did modestly lower glucose levels during an oral glucose tolerance test (OGTT). Until more is known, use cautiously.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, concomitant use of Baikal skullcap with antihypertensive drugs might have additive effects and increase the risk of hypotension.
Animal research suggests that baicalein, a constituent of Baikal skullcap, might lower blood pressure.

Likelihood Possible Evidence D
Antithyroid Drugs

Theoretically, concomitant use of Baikal skullcap and antithyroid drugs may result in additive activity and increase the risk of hypothyroidism.
In an animal hyperthyroid model, Baikal skullcap improved levels of triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH). The clinical significance of this effect is unclear.

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

Theoretically, Baikal skullcap may increase levels of drugs metabolized by CYP1A2 enzymes.
In vitro evidence suggests that constituents of Baikal skullcap inhibit the activity of CYP1A2. This effect has not been reported in humans.

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

Theoretically, Baikal skullcap might increase levels of drugs metabolized by CYP2C19 enzymes.
In vitro evidence suggest that wogonin, a constituent of Baikal skullcap, modestly inhibits the activity of CYP2C19 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of large amounts of Baikal skullcap might interfere with hormone replacement therapy, due to competition for estrogen receptors.
In vitro evidence suggests that Baikal skullcap has estrogenic activity.

Likelihood Possible Evidence D
Lithium

Theoretically, Baikal skullcap might reduce lithium excretion and increase serum levels of lithium.
Baikal skullcap is thought to have diuretic properties, which may reduce lithium excretion. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Alcohol (Ethanol)

Theoretically, Baikal skullcap might potentiate the sedative effects of alcohol.
In vitro and animal research suggests that Baikal skullcap binds to GABA-A receptors and causes sedation. Theoretically, Baikal skullcap might potentiate the sedative effects of alcohol. Preliminary clinical research has not identified clinically relevant sedation after use of Baikal skullcap; however, a thorough evaluation of safety outcomes has not been conducted.

Likelihood Unlikely Evidence D
Cns Depressants

Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties.
In vitro and animal research suggests that Baikal skullcap binds to GABA-A receptors and causes sedation. Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties. Preliminary clinical research has not identified clinically relevant sedation after use of Baikal skullcap; however, a thorough evaluation of safety outcomes has not been conducted.

Likelihood Unlikely Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, Baikal skullcap might alter the levels and clinical effects of OATP substrates.
Some pharmacokinetic research shows that baicalin, a constituent of Baikal skullcap, can decrease plasma levels of rosuvastatin. The mechanism is thought to involve stimulation of the activity of the organic anion-transporting polypeptide 1B1 (OATP1B1), which transports rosuvastatin into the liver. This decreases plasma levels of the drug, but increases levels at the site of action in the liver. The degree to which rosuvastatin levels are affected depends on the OATP1B1 haplotype of the individual. Baikal skullcap might also affect other OATP1B1 substrates.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Theoretically, Baikal skullcap might increase levels of drugs transported by P-glycoprotein.
In vitro and animal research suggests that baicalein, oroxylin A, and wogonin, constituents of Baikal skullcap, can inhibit P-glycoprotein. This effect has not been reported in humans.

Moutan7 drug types · 811 drugs

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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Tienchi4 drug types · 207 drugs

Aspirin

Theoretically, taking Panax notoginseng concomitantly with aspirin may increase the risk of adverse effects from both products.
Animal research shows that taking Panax notoginseng extract with aspirin increases blood levels of salicylic acid by approximately 50% and blood levels of Panax notoginseng by 75% to 196%. This effect may be due to increased absorption of both products.

Likelihood Possible Evidence D
Caffeine

Theoretically, taking Panax notoginseng may decrease the levels and clinical effects of caffeine.
Animal research shows that administering Panax notoginseng intravenously for 7 days before intraperitoneal injection of caffeine can decrease maximal blood levels of caffeine by 37%. This interaction is attributed to the ability of Panax notoginseng to increase the activity of cytochrome P450 1A2 (CYP1A2) enzymes.

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

Theoretically, taking Panax notoginseng might reduce the levels and clinical effects of CYP1A2 substrates.
Animal research shows that administering Panax notoginseng intravenously for 7 days before intraperitoneal injection of caffeine can decrease maximal blood levels of caffeine by 37%. This interaction was attributed to the ability of Panax notoginseng to increase the activity of CYP1A2.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, taking Panax notoginseng concomitantly with warfarin may increase the risk of bleeding.
Animal research shows that taking Panax notoginseng concomitantly with warfarin increases plasma warfarin levels, prothrombin time, and international normalized ratio when compared with control. In vitro research also suggests that Panax notoginseng may downregulate expression of cytochrome P450 3A4 enzymes, which may affect warfarin metabolism.

Warfarin (Coumadin)

Dong quai may increase the risk of bleeding when used with warfarin.
Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding. In one case, after 4 weeks of taking dong quai 565 mg once or twice daily, the international normalized ratio (INR) increased to 4.9. The INR normalized 4 weeks after discontinuation of dong quai.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components. Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin. However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding. Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.

Likelihood Possible Evidence D
Estrogens

Theoretically, dong quai may reduce the effects of estrogens.
Dong quai has estrogenic effects. Theoretically, concomitant use of large amounts of dong quai might interfere with hormone replacement therapy due to competition for estrogen receptors.
