HelloPharmacist Scorecard of Jing 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
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 10 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.

Jing contains 10 ingredients, of which most are herbal extracts sourced from traditional Chinese medicine. The active ingredients are astragalus root extract, codonopsis root extract, rehmannia root extract (both processed and raw forms), eucommia bark extract, cornus fruit extract, phellodendron bark extract, Chinese asparagus root extract, ophiopogon tuber extract, and dendrobium extract.

There's also a proprietary extract blend listed as a separate ingredient. The product is filled out with inactive ingredients—pullulan polysaccharide (the capsule material), rice powder, bamboo extract powder, and rice extract blend—which serve as binders and fillers.

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: Chronic kidney disease (CKD) — rated "Possibly Effective" (Rehmannia) (Natural Medicines).

The evidence supporting Jing's ingredients is limited. Rehmannia root (in both its processed and raw forms) is rated possibly effective for chronic kidney disease; that's the strongest claim we can make from the data we hold.

For most of the other ingredients and traditional uses listed—astragalus for allergic rhinitis, asthma, anemia, and angina; codonopsis for asthma, cancer, respiratory infections, digestive upset, and cholesterol; rehmannia for diabetes, diabetic kidney damage, bone health, and atopic conditions; phellodendron for acne, prostate health, diabetes, weight, arthritis, and ulcers; dendrobium for any condition—the evidence is insufficient to establish whether they work. The product is marketed as a traditional tonic, but modern clinical support for its overall formula isn't established in the data available to us.

The evidence, ingredient by ingredient Astragalus Codonopsis Rehmannia American Dogwood Phellodendron Dendrobium

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 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.

Astragalus and codonopsis are generally well tolerated in the short term in healthy adults, though human safety data are limited for both. Codonopsis at very high doses (30–60 grams) has been reported to cause chest pain, arrhythmia, and throat pain or voice loss; it can also trigger allergic reactions including anaphylaxis in sensitive individuals.

Astragalus has been associated with dizziness and, in one trial, with a type of chest pain called lacunar angina, though a causal link isn't certain. Rehmannia (both forms) and phellodendron are generally used in traditional medicine but with limited modern safety data.

Phellodendron-containing products have been linked to sexual dysfunction, shaking hands, numbness around the mouth, fatigue, headache, and heartburn in a combination product, though a causal relationship is unclear. Dendrobium has not been thoroughly evaluated for safety, and one adverse event report involved a combination product later found to contain amphetamine-like ingredients, making it unclear what dendrobium itself contributes.

We hold very limited or no human safety data for cornus fruit, eucommia bark, Chinese asparagus root, and ophiopogon tuber.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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

Why this rating?
  • 5 of the 6 matched ingredients can interact with medications — Codonopsis, Astragalus, Phellodendron, Rehmannia, Dendrobium.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; seizure medications; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,440 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 start Jing, check with your doctor or pharmacist about any medications you take in these categories: drugs that lower seizure threshold or anticonvulsants (due to dendrobium), any drug metabolized by the CYP3A4 liver enzyme (phellodendron), blood thinners (anticoagulants and antiplatelets, from phellodendron and codonopsis), blood pressure drugs (phellodendron, rehmannia, and dendrobium), diabetes medications (astragalus, codonopsis, rehmannia, and phellodendron), sleeping pills and other CNS depressants (phellodendron), lithium (astragalus), cyclophosphamide (astragalus), abiraterone (codonopsis), drugs metabolized by CYP2D6 or CYP2C9 (phellodendron), and metformin (phellodendron). The most serious risk is from phellodendron's effect on CYP3A4 drug metabolism.

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.

Jing is a multi-ingredient herbal formula with significant documented interactions across a large range of medications—especially those metabolized by liver enzymes, blood thinners, blood pressure drugs, diabetes drugs, and seizure medications. The effectiveness evidence for its ingredients is sparse; only rehmannia for chronic kidney disease reaches a "possibly effective" rating.

If you take any prescription medications, especially for blood pressure, diabetes, seizures, blood clotting, or heart rhythm, run them through this page's medication checker before adding Jing. Discuss the results and whether this product makes sense for you with your own doctor or pharmacist.

Phellodendron bark extract14 drug types · 1,160 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, phellodendron might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Phellodendron contains berberine. In vitro and in vivo research suggest that berberine can inhibit platelet aggregation. Theoretically, phellodendron might also inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, phellodendron may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Phellodendron contains berberine. Clinical research shows that berberine may lower blood glucose levels. Theoretically, phellodendron might also lower blood glucose levels.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, phellodendron might have additive effects with antihypertensive drugs.
Phellodendron contains berberine. Animal research suggests that berberine can have hypotensive effects. Also, a clinical study suggests that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone. Theoretically, phellodendron might also reduce blood pressure.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, phellodendron might increase the sedative effects of CNS depressants.
Phellodendron contains berberine. Animal research suggests that berberine may have sedative effects. Theoretically, phellodendron might also have CNS depressants effects.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, phellodendron might increase blood levels of cyclosporine.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can reduce metabolism of cyclosporine and increase serum levels, likely through inhibition of cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine. Theoretically, phellodendron might also reduce the metabolism of cyclosporine.

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

Theoretically, phellodendron might increase serum levels of drugs metabolized by CYP2C9.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can inhibit CYP2C9. Theoretically, phellodendron might also inhibit CYP2C9.

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

Theoretically, phellodendron might increase serum levels of drugs metabolized by CYP2D6.
Phellodendron contains berberine. In vitro research and preliminary clinical evidence show that berberine can inhibit CYP2D6. Theoretically, phellodendron might also inhibit CYP2D6.

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

Theoretically, phellodendron might increase serum levels of drugs metabolized by CYP3A4.
Phellodendron contains berberine. In vitro research and preliminary clinical research show that berberine moderately inhibits CYP3A4. Theoretically, phellodendron might also inhibit CYP3A4.

Likelihood Possible Evidence D
Dextromethorphan (Robitussin Dm, Others)

Theoretically, phellodendron may increase serum levels of dextromethorphan.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan. Theoretically, phellodendron may also inhibit the metabolism of dextromethorphan.

Likelihood Possible Evidence D
Losartan (Cozaar)

Theoretically, phellodendron might reduce the therapeutic effects of losartan by decreasing its conversion to its active form.
Phellodendron contains berberine. Preliminary clinical research suggests that berberine can inhibit cytochrome P450 2C9 (CYP2C9) activity and reduce metabolism of losartan. Theoretically, phellodendron might also inhibit the metabolism of losartan.

Likelihood Possible Evidence D
Metformin (Glucophage)

Theoretically, phellodendron might increase the therapeutic and adverse effects of metformin.
Phellodendron contains berberine. In vitro and animal studies show that berberine can increase the systemic exposure and half-life of metformin, potentially increasing metformin's effects and side effects. This interaction seems to be most apparent when berberine is administered 2 hours prior to metformin. Taking berberine and metformin at the same time does not appear to increase systemic exposure to metformin. It is unclear if phellodendron might have this same effect.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, phellodendron might reduce metabolism of midazolam, which might increase the risk of severe adverse effects.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can inhibit cytochrome P450 3A4 (CYP3A4) activity and reduce metabolism of midazolam. Theoretically, phellodendron might also inhibit the metabolism of midazolam.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, phellodendron might increase the sedative effect of pentobarbital.
Phellodendron contains berberine. Animal research shows that berberine can prolong pentobarbital-induced sleeping time. Theoretically, phellodendron might increase the sedative effects of pentobarbital.

Likelihood Possible Evidence D
Tacrolimus (Prograf)

Theoretically, phellodendron might increase blood levels of tacrolimus.
Phellodendron 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 the tacrolimus dose to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL. It is unclear if phellodendron might have this same effect.

Likelihood Possible Evidence D
Phellodendron bark extract full monograph & interactions

Dendrobium extract3 drug types · 609 drugs

Anticonvulsants

Likelihood Possible Evidence D
Rehmannia Root Extract full monograph & interactions

Codonopsis root extract3 drug types · 211 drugs

Abiraterone (Zytiga)

Theoretically, taking codonopsis root with abiraterone might reduce the levels and therapeutic effects of abiraterone.
Animal research in rats shows that intragastric administration of codonopsis root along with abiraterone every 2 days for 2 weeks seems to increase the clearance of abiraterone and reduce the overall exposure and time to maximum concentration. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, codonopsis liquor might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
A small clinical study in adults with coronary heart disease shows that consuming Codonopsis pilosula liquor for 4 weeks inhibits platelet aggregation but does not affect tissue-type plasminogen activator (t-PA) or plasminogen activator inhibitor (PAI).

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, codonopsis might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Laboratory and animal research suggest that codonopsis has antidiabetic effects.

Likelihood Probable Evidence A
Cyclophosphamide

Theoretically, astragalus might interfere with cyclophosphamide therapy.
Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression. However, other animal research shows no effect.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, astragalus might interfere with immunosuppressive therapy.
Astragalus seems to stimulate immune function. Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, astragalus might increase levels and adverse effects of lithium.
Animal research suggests that astragalus has diuretic properties. Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.

Jing by Ron Teeguarden's Dragon Herbs: Common Questions

Does Jing by Ron Teeguarden's Dragon Herbs interact with any medications?
Yes. Based on its ingredients, Jing has a known interaction with 1,439 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Jing contains 10 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 Jing while pregnant or breastfeeding?
No. Several of the ingredients—astragalus, codonopsis, rehmannia, and dendrobium—are best avoided during pregnancy due to insufficient safety data. Phellodendron is considered likely unsafe in pregnancy. While breastfeeding, most of these ingredients should also be avoided because there isn't enough safety information, and phellodendron's berberine may pass to your infant. Talk with your doctor or pharmacist before taking Jing if you're pregnant, nursing, or planning either.
What is Jing supposed to do?
Jing is marketed as a traditional tonic formula from Chinese herbal medicine. The product facts don't specify a single intended use; the formula blends multiple ingredients historically used in that tradition. However, the modern clinical evidence supporting any of these ingredients is limited—only rehmannia is rated possibly effective, for chronic kidney disease.
Could Jing interact with my blood pressure medication?
Yes, potentially. Rehmannia (in both forms), phellodendron, and dendrobium all carry Moderate or Minor risks of lowering blood pressure beyond intended levels when combined with blood pressure drugs. Before starting Jing, check with your doctor or pharmacist about your specific medication.
Does Jing have side effects?
Most side effects reported are rare or from combination products, so it's unclear which ingredient caused them. That said, codonopsis at very high doses can cause chest pain and throat issues, and it can trigger allergic reactions including severe ones in sensitive people. Astragalus has been linked to dizziness in some reports. Overall, human safety data for these ingredients are limited.
What if I'm taking diabetes medication?
Multiple ingredients in Jing—astragalus, codonopsis, rehmannia, and phellodendron—may increase the risk of low blood sugar (hypoglycemia) when combined with diabetes drugs. Additionally, phellodendron may amplify metformin's effects and side effects. Check your specific medications with your doctor or pharmacist before starting.
Can Jing interact with blood thinners?
Yes. Both codonopsis and phellodendron carry Moderate risks of increased bleeding when combined with blood thinners (anticoagulants or antiplatelets). If you take a blood thinner, discuss this product with your doctor or pharmacist first.
